DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 6 The present invention provides the following technical solutions: Embodiment 1 of greenhouse picking auxiliary lifting trolley: By setting a stopper 10 to block the feeding port 9, the normal use of the vehicle body 1 is facilitated. Figure 1 and Figure 2 As shown: it includes a vehicle body 1, which is a structure that is wide at the top and narrow at the bottom, and handles 2 are fixedly connected to both ends of the right side of the vehicle body 1, and the handles 2 are inverted "L" structures when viewed from the side, and connecting shafts 3 are rotatably arranged between adjacent handles 2. It also includes a lap block 6, a cross bar 7, a stopper 10 and a vertical plate 11. The lap block 6 is fixedly connected to the lower surface of the vehicle body 1, and a long pin 4 is rotatably arranged inside the lap block 6, and rollers 5 are fixedly connected to the ends of both sides of the long pin 4. The cross bar 7 is fixedly connected to the inner wall of the vehicle body 1, and a column 8 is fixedly connected to the lower surface of the cross bar 7, and a feed opening 9 is opened on the lower surface of the vehicle body 1. The stopper 10 is sleeved and connected to the surface of the column 8. The vertical plate 11 is fixedly connected to the lower surface of the vehicle body 1, and a fixed block 14 is slidably provided on the surface of the vehicle body 1, and the end of the fixed block 14 is fixedly connected to a support block 12, the support block 12 is a triangular structure when viewed from the front, and the upper surface of the support block 12 is in contact with the lower surface of the stop block 10, and the stop block 10 passes through the interior of the vehicle body 1.

[0023] When in use, the operator pushes the vehicle body 1 through the handle 2 and the connecting shaft 3, and the vehicle body 1 moves forward and backward under the action of the long pin 4, the overlap block 6 and the roller 5. During use, the stopper 10 inside the vehicle body 1 is supported by the support block 12, so that the feed port 9 is blocked and the fruit will not leak out.

[0024] Embodiment 2: Different from Embodiment 1, the lifting structure can be used to open the feeding port 9 to facilitate the discharge of fruits from the vehicle body 1. Figure 3-Figure 5As shown: a traction rope 16 is fixedly connected to the right surface of the support block 12, and the surface of the traction rope 16 fits with the surface of the connecting shaft 3, and a gravity ball 17 is fixedly connected to the end of the traction rope 16, the fixed block 14 is symmetrically distributed about the center of the support block 12, the surface of the vertical plate 11 is concave, and a limit rod 13 corresponding to the fixed block 14 is fixedly connected to the inner wall of the vertical plate 11.

[0025] When it is necessary to discharge the fruits inside the vehicle body 1, the operator can directly pull the gravity ball 17, so that the gravity ball 17 drives the support block 12 to slide to the right through the traction rope 16, and then the block 10 drops in the vertical direction under the action of its own gravity and the column 8, and then the discharge port 9 is opened. At this time, the fruits are discharged from the lower side of the vehicle body 1, and when the support block 12 is pulled and slid by the traction rope 16, the support block 12 will drive the fixed block 14 to slide inside the vertical plate 11, and the limit rod 13 makes the fixed block 14 and the support block 12 slide only in the horizontal direction, ensuring stability.

[0026] Embodiment 3: Different from Embodiment 2, the reset spring 15 can make the support block 12 and the stopper 10 return to their original positions quickly, which is convenient for subsequent use.

[0027] When the stopper 10 descends, the stopper 10 will eventually contact the support rod 18. The support rod 18 limits the final descending distance of the stopper 10, so that the stopper 10 will not fall, thereby ensuring the working stability of the stopper 10. When the fixed block 14 slides, the reset spring 15 will be squeezed. When it is necessary to return the stopper 10 to its original position and block the discharge port 9 again, the gravity ball 17 can be released. At this time, the support block 12 and the fixed block 14 will return to their original positions under the action of the reset spring 15, and then the stopper 10 will be pushed back to its original position by the support block 12, which is convenient for subsequent use.
