A product transfer assembly includes separate transfer segments mounted in a vending machine such that they are disposed in spaced relationship above one another. Each transfer segment has a ramp of helical shape with an exit end and an entrance end spaced above the exit end such that the ramps of the transfer segments together define a path of travel taken by a product item down and in contact with the ramps which includes spaced apart portions helical in shape and reversing the direction of travel of the product item, relative to a generally vertical reference axis, going from one portion to the next portion of the path. Entrance and exit ends of each ramp are angularly displaced from corresponding ends of an adjacent ramp such that the object free-falls out of contact with any ramp between the exit and entrances ends of adjacent ramps.

The invention discloses a pomelo picking equipment, which comprises a supporting platform, a standing platform, a vertical guardrail and a folding plate. A standing platform is installed on the upper end of the supporting platform, and a ladder fixing part is welded on the outer side of the standing platform. The ladder fixing part There are four, ladders are welded between the ladder fixing parts, the upper end of the support platform is connected with a horizontal guardrail through a vertical guardrail, and a guardrail door is installed on one side of the upper end of the standing platform, and a latch is installed on the guardrail door. , the bolt is inserted into the bolt hole through the bolt fixing part, the bolt hole is welded on the vertical guardrail on the side close to the bolt, the side of the guardrail door away from the bolt is equipped with a folding plate through a rivet, and the side away from the bolt is vertical Folding panels are attached to the guardrail via rivets. The invention can conveniently pick high-altitude pomelo, and after picking, the pomelo can be conveniently moved to the ground through a spiral slide, which is convenient for transportation, reduces damage caused by free falling of the pomelo, improves work efficiency, and is safe and reliable.

The invention discloses a teaching apparatus for comparing oblique projectile with motion of free falling body, which comprises a push rod motor fixed at the top part of a base; an output shaft of thepush rod motor is fixed with an installing plate, and the top part of the installing plate is fixed with a guide rod; a front face of the guide rod is provided with a T-shaped chute in height direction, and a T-shaped slide block is glidingly sleeved in the T-shaped chute; the bottom part of the T-shaped slide block is provided with a cutter, and the top part of the T-shaped slide block is connected with a first spring fixed on the inner wall of the top part of the guide rod. Through cooperative use of a pull line, an adjusting screw, a guide plate, a second spring, a connecting sleeve, a guide pillar, a T-shaped push block, an oblique projectile ball, and other structures, the oblique projectile ball can obliquely throw in the dip angle direction of the guide plate, so as to simulate theoblique projectile movement; the oblique projectile angle can be adjusted as required, the teaching apparatus is flexible in use, simple in whole structure, low in manufacturing cost, simple and easyto operate, and can deepen study impression.

The present invention relates to an oblique projectile motion and free-fall motion contrast teaching instrument. The instrument comprises a first board, a wire, an electromagnet, a battery pack, a switch, a small ball, a stainless steel pipe, a bare conductor and a transparent adhesive tape. The first board is horizontally arranged and is vertically connected with a second board, a third board and a fourth board through nails; the stainless steel pipe is arranged on the second board, the third board and the fourth board; the small ball is arranged at the entrance in the stainless steel pipe; the electromagnet, the battery pack, the switch and the stainless steel pipe are connected through the wire in order; the bare conductor is pasted at two sides of the stainless steel pipe through the transparent adhesive tape; and a coin is absorbed at the bottom portion of the electromagnet, and the tangent line of the stainless steel pipe passes through the center of the coin. According to the oblique projectile motion and free-fall motion contrast teaching instrument, all the devices are stored in a toolset through pulling put nails when the oblique projectile motion and free-fall motion contrast teaching instrument is not used, and the oblique projectile motion and free-fall motion contrast teaching instrument is ingenious in design, low in manufacturing cost and convenient to carry, etc.
