Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse vegetable conveying equipment, in particular to an automatic greenhouse vegetable conveying device, which is used for conveying vegetables picked in the greenhouse to outside the greenhouse. Background Art

[0002] The greenhouse is composed of cement poles, light steel pipes or pipes as the skeleton, columns, pull rods, arch rods and pressure rods, covered with plastic film to form an arched material shed. The greenhouse was originally a special equipment for vegetable cultivation. With the development of modern agriculture, the application of greenhouses has become more and more extensive. At present, greenhouse vegetable cultivation has become the main source of income for many farmers, but in the current greenhouses, the transportation of vegetables mainly relies on manual handling, which is labor-intensive and inefficient, and cannot meet the needs of rapid production in modern agriculture.

[0003] CN205397319U discloses a greenhouse vegetable hanging conveyor, which uses a storage platform to place baskets filled with vegetables, and transports the vegetables by moving the storage platform. Although the transportation method of the storage platform has good stability, the overall volume and weight are large, the transportation capacity is limited, and when in use, the telescopic rod needs to be pulled down to lower the storage platform and keep it for a certain period of time so that the vegetable basket can be placed on the storage platform. When using it, at least two people are required to cooperate, which also increases the labor cost invisibly. Utility Model Content

[0004] In view of the above problems, the inventor provides an automatic conveying device for greenhouse vegetables, which uses a hanging method to transport baskets full of vegetables, so as to improve the work efficiency of vegetable transportation in the greenhouse and reduce labor intensity.

[0005] Specifically, the utility model is achieved as follows:

[0006] An automatic conveying device for greenhouse vegetables comprises: a track suspended on an arched shed frame of the greenhouse and a suspension mechanism arranged on the track, wherein the track is a track, and the suspension mechanism comprises:

[0007] There are multiple pulleys, and the multiple pulleys are slidably connected to the track, and the multiple pulleys are connected to form a pulley group;

[0008] A pulley driving device, connected to any pulley, for driving the pulley assembly to move on the track;

[0009] The hanging device is arranged below the pulley and is used for hanging the container for storing vegetables.

[0010] Furthermore, the pulley comprises:

[0011] The mounting base is L-shaped as a whole;

[0012] A first roller is vertically arranged inside the mounting seat and in contact with the track; an output shaft of the pulley driving device is connected to the first roller;

[0013] The second roller is horizontally arranged inside the mounting seat and in contact with the track; the first roller and the second roller are respectively located on both sides of the track.

[0014] Furthermore, a traction steel rope installation hole is provided on the mounting seat, and two adjacent pulleys are connected by a traction steel rope, and the traction steel rope is fixedly connected to the mounting seat through the traction steel rope installation hole.

[0015] Furthermore, the hanging device comprises:

[0016] A winding reel is arranged at the bottom of the mounting seat, and is provided with a hanging rope, and a hook is provided at the end of the hanging rope;

[0017] A ratchet wheel is arranged outside the cable reel and is coaxial with the cable reel;

[0018] The ratchet is arranged on the outside of the cable reel and is matched with the ratchet wheel. The ratchet wheel and the ratchet cooperate with each other to limit the unwinding of the cable reel so as to lock the height of the hook.

[0019] Furthermore, the cable reel is an automatic retractable cable reel with a built-in coil spring.

[0020] Furthermore, the hanging device also includes: a protective shell, the winding reel, ratchet and ratchet are arranged in the protective shell, the lower part of the protective shell is provided with a hanging rope outlet, and the outer side of the end of the protective shell close to the ratchet is provided with an adjusting button, the adjusting button is connected to the ratchet, and is used to rotate the ratchet to limit the rotation of the ratchet or release the restriction on the rotation of the ratchet.

[0021] Furthermore, two of the first roller and two of the second roller are provided.

[0022] Furthermore, the pulley comprises:

[0023] At least two concave rollers are placed on the track and slide along the track, and the two concave rollers are connected by a mounting plate.

[0024] Working principle:

[0025] For the method in which the height is not adjustable: the pulley driving device 3 drives the concave roller to move along the track 1, and under the rigidity of the traction steel rope 5, the entire pulley assembly is driven to move along the track, and the vegetable basket is hung on the hook 41 of the pulley 2, so that the vegetable basket can be automatically transported.

[0026] For the non-adjustable height method: before use, first rotate the ratchet 46 to release the restriction on the ratchet 45, then pull the hook 41, and the winding drum 43 will release the line. After the hook 41 reaches the appropriate position, reset the ratchet 46 to maintain the restriction on the ratchet 45, thereby limiting the rotation of the winding drum 43 and keeping the hook 41 at this height.

[0027] After the heights of all hooks 41 are adjusted appropriately, the pulley drive device 3 drives the first roller 22 to move along the track, and synchronously drives the second roller 23 to rotate during the movement to ensure the stability of the movement. After two adjacent pulleys 2 are connected by the traction steel rope 5, when one of the pulleys 2 starts to move, it will drive all the pulleys 2 to move synchronously, so that the entire pulley group can move along the circular track 1. When the driven pulley 2 stops, all the pulleys 2 will also stop synchronously under the rigidity of the traction steel rope 5. During the actual transportation process, the pulley group keeps moving slowly so that the pickers can hang the baskets full of vegetables on the hooks 41.

When running in the forward direction, the head active pulley is driven and the rear active pulley is stopped to drag the heavy vegetable basket out of the greenhouse; when running in the reverse direction, the head active pulley is stopped and the rear active pulley is driven to drag the empty vegetable basket into the greenhouse.

[0031] (3) The hanging method makes the volume smaller, and one person can complete the "loading" operation. Moreover, under the action of the gravity of the vegetables, the transportation can still be relatively stable.

[0032] (4) The hook is height-adjustable and can be retracted to a high position when vegetables are not being picked and transported, thereby reducing the space occupied in the greenhouse and preventing the hook from interfering with people in the greenhouse. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0045] Example 1

[0046] like Figure 1-2 As shown, the utility model provides an automatic conveying device for greenhouse vegetables, comprising: a track 1 suspended on an arched trellis of the greenhouse and a suspension mechanism arranged on the track 1, wherein the track 1 is a ring track made of C-shaped steel or I-shaped steel, thereby forming a closed-loop continuous automatic assembly line in the greenhouse, replacing manual carrying.

[0047] Specifically, the suspension mechanism includes: a pulley drive device 3 (servo motor), a plurality of pulleys 2 slidably connected to the track 1, and a hanging device 4 fixedly connected to the pulley 2. The plurality of pulleys 1 are fixedly connected by a connecting rod or a rope with a certain rigidity. In this embodiment, a traction steel rope 5 is used for connection to form a pulley group connected end to end. The pulley drive device 3 is connected to any pulley 2 to drive the pulley 2 to slide on the track 1, thereby driving all pulleys 2 to move. It should be understood that the number and spacing of the pulleys 2 can be combined at will according to the size of the planting greenhouse area. The greenhouse vegetable automatic conveying device is suspended and installed on the roof of the planting greenhouse. The conveying system has a simple structure, low energy consumption, does not occupy the planting ground, does not hinder labor, occupies a small space, can realize continuous transportation, and greatly reduces labor costs.

[0048] Furthermore, if Figure 3-4 As shown, the pulley 2 includes: a mounting seat 21, a first roller 22 and a second roller 23. The mounting seat 21 is L-shaped, and the axes of the first roller 22 and the second roller 23 are perpendicular to each other. The first roller 22 and the second roller 23 are both provided with two, which not only ensures that the pulley 2 can move along the track 1, but also ensures the stability of the operation and reduces the risk of derailment. Among them, the first roller 22 is vertically arranged on the inner side of the mounting seat 21, and the second roller 23 is horizontally arranged on the inner bottom surface of the mounting seat 21. The first roller 22 and the second roller 23 are respectively located on both sides of the track 1, and the first roller 22 contacts the bottom of the track 1, and the second roller 23 contacts the side wall of the track 1, so that the first roller 22 and the second roller 23 are located in the steel groove, thereby ensuring the stability of the pulley 2 during operation.

[0049] The output shaft of the pulley driving device 3 is connected to any first roller 22 of any pulley 2, and the first roller 22 is driven to roll by the rotation of the output shaft. A traction steel rope mounting hole 24 is provided on the mounting seat 21, and the traction steel rope 5 is fixedly connected to the mounting seat 24 through the traction steel rope mounting hole 24, so that all pulleys 2 are connected in series to form an overall unified pulley group. After two adjacent pulleys 2 are connected by the traction steel rope 5, when one of the pulleys 2 starts to move, it will drive all the pulleys 2 to move synchronously, so that the entire pulley group can move along the track 1. When the driven pulley 2 stops, all the pulleys 2 will also stop synchronously under the rigidity of the traction steel rope 5. In the actual transportation process, the pulley group keeps a slow moving state so that the pickers can hang the basket full of vegetables on the hook 41 or place the vegetables in the basket on the hook 41.

[0050] Furthermore, the hanging device 4 includes: a protective shell 42, a cable reel 43, a ratchet 45, a ratchet 46 and a hook 41. The protective shell 42 is arranged at the bottom of the mounting seat 21, and a hanging rope outlet is arranged at the bottom. The cable reel 43 is an automatic retractable cable reel with a built-in coil spring 43, which is arranged in the protective shell 42, and a hanging rope 44 is stored thereon. The end of the hanging rope 44 extends out of the hanging rope outlet, and the hook 41 is arranged at the end of the hanging rope 44. A ratchet 45 and a ratchet 46 are arranged on the outside of the cable reel 43. The ratchet 45 is coaxial with the cable reel 43. An adjustment button 47 is arranged on the outside of one end of the protective shell 42 close to the ratchet 46. The adjustment button 47 is connected to the ratchet 46 and is used to rotate the ratchet 46 to limit the rotation of the ratchet 45 or release the restriction on the rotation of the ratchet 45. When the ratchet 46 abuts against the ratchet 45, the cable reel 43 is restricted from rotating in the unwinding direction, thereby preventing the hook 41 from continuously falling under the influence of gravity after the vegetable basket is hung. After the vegetable transportation is completed, the ratchet 46 is opened to release the restriction on the winding drum 43, and the winding spring 43 is used to reel the hanging rope 44 around the winding drum 43, and the hook 41 is retracted to a high position to prevent the hook 41 from interfering with the personnel in the greenhouse.

[0051] The hook 41 is adjustable, so that the hanging height of the vegetable basket can be adjusted. The height can be adjusted in combination with the growth height of various vegetables and the comfort of human-machine operation, so that the vegetable pickers can directly and conveniently put the vegetables into the conveying basket without getting them stained with dirt. In addition, considering the convenience of loading vegetables, a light, rigid, and side-railed dish-shaped vegetable basket can be selected. The smooth surface will not damage the vegetables, and it is also convenient for preliminary sorting and testing. If a dish-shaped conveying basket is selected, the vegetables can be evenly spread in the dish, and the state of the vegetables is dynamically presented, which is very conducive to sorting and testing, and it is convenient for workers to quickly and directly pick out unqualified vegetables.

The pulley group is composed of a plurality of pulleys 2, and the first and last pulleys 2 are provided with pulley driving devices 3, and the two pulley driving devices 3 are respectively used to control the pulley group to move in two directions along the track 1.

[0054] like Fig. 9As shown, the pulley 2 is composed of two concave rollers 25, which are connected by a mounting plate 26, and two adjacent pulleys 2 are connected by a traction steel rope 5, which is connected to the mounting plate 26, so that the pulleys 2 form a linear pulley group. A hook 41 is set below the mounting plate 26, and each pulley 2 corresponds to two hooks 41, which together hang a vegetable basket 6. Preferably, the middle groove depth of the concave roller 25 is greater than the radius of the circular tube track 1, so that the track 1 is sufficiently in contact with the concave roller 25, and the stability during the movement is ensured by the two concave rollers 25 and the hook 41.
