[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] As attached Figure 1-6 A vegetable packing and stacking device shown in the figure includes a conveying device 1 and a lifting device 2, wherein the conveying device 1 includes a main frame 10, a driving motor 11 is arranged on the surface of the main frame 10, and a motor chain 12 is meshed with a sprocket at the output end of the driving motor 11, and a plurality of driving rollers 13 are arranged inside the main frame 10, both ends of the driving roller 13 extend to the inside of the main frame 10, and two conveying chains 14 are arranged on the top of the main frame 10, the connection between the motor chain 12 and the driving roller 13 is meshed with each other by a sprocket, and the two conveying chains 14 on the top of the main frame 10 are connected to the driving roller 13 through a sprocket, and two groups of stop plates 3 are arranged at the end of the main frame 10 to which the conveying device 1 belongs, and an in-place inspection photoelectric device 4 is arranged between the two groups of stop plates 3.

[0021] Specifically, in this structure, the function of the conveying device 1 is to convey the pallets for vegetable packing. Specifically, first, the driving motor 11 inside the main frame 10 drives the sprocket wheel (not shown in the figure) to rotate so that the meshing motor chain 12 can be operated, and the motor chain 12 drives multiple driving rollers 13 to rotate inside the main frame 10 through the sprocket wheel (not shown in the figure). During the rotation of the multiple driving rollers 13 inside the main frame 10, the corresponding sprocket wheels are used again to drive the two conveying chains 14 on the top of the main frame 10 to operate, and the pallets for vegetable packing are placed on the two conveying chains 14. The operation of the two conveying chains 14 drives the pallets to move, thereby realizing the transportation of the pallets.

[0022] Specifically, when the pallet is transported to the position of the lifting device 2, it will accidentally hit the stop plate 3 and trigger the in-place inspection photoelectric device 4. At this time, after the in-place inspection photoelectric device 4 detects the signal that the pallet has arrived, the drive motor 11 stops running, so that the pallet can accurately reach the position of the lifting device 2.

[0023] In a specific embodiment, as shown in the attached Figure 1 As shown, guide plates 5 are symmetrically installed on both sides of the main frame 10 to which the conveying device 1 belongs by bolts, and the two guide plates 5 are in a horizontal state with the corresponding conveying chains 14.

[0024] Specifically, in this structure, in order to ensure that the pallet does not have the risk of falling during transportation, two symmetrically arranged guide plates 5 are installed at the main frame 10, which can guide the pallet during transportation and ensure that the pallet can be transported stably.

[0025] In this embodiment, specifically, the lifting device 2 includes two fixed frames 20, which are mounted on the corresponding main frame 10 by bolts, two vertical rails 21 are arranged inside the fixed frame 20, and a lifting frame 22 is arranged between the two vertical rails 21, and a telescopic device 23 is installed on the lifting frame 22, a lifting motor 24 is arranged inside the main frame 10 and on a side away from the driving motor 11, and a lifting chain 25 is meshed with the output end of the lifting motor 24 through a sprocket, and a plurality of crankshaft assemblies are arranged inside the main frame 10. Part 26, two guide wheels 6 are provided at both ends of the jacking frame 22, and the two ends of the jacking frame 22 are slidably connected inside the two vertical guide rails through the guide wheels 6. The number of telescopic devices 23 is set to two groups, and the two groups of telescopic devices 23 are respectively installed on the corresponding jacking frames 22, and the number of each group of telescopic devices 23 is set to two, and the two groups of telescopic devices 23 are symmetrically distributed. The jacking chain 25 and the crankshaft assembly 26 are meshed with each other through a sprocket, and one end of the crankshaft assembly 26 is inside the fixed frame 20 and at the bottom of the jacking frame 22.

[0026] Specifically, in this structure, the lifting device 2 is mainly used to lift the transported pallet by clamping. The specific principle is that when the pallet is transported by the conveying device 1 and reaches the position of the lifting device 2, the two sets of symmetrically distributed telescopic devices 23 are first extended and located at the bottom of the vegetable box pallet to clamp the vegetable box pallet, so as to facilitate the later lifting of the vegetable box pallet.

[0027] The lifting motor 24 is running, and the output end of the lifting motor 24 drives the sprocket wheel (not shown) to rotate, and makes the lifting chain 25 run, and the lifting chain 25 drives the crankshafts of multiple crankshaft assemblies 26 (not shown) to rotate through the sprocket wheel, and the rotation of the crankshaft drives the crank block to rise and lift the lifting frame 22, so that the two ends of the lifting frame 22 are guided upward by sliding inside the vertical track 21 through the guide wheel 6, and the two sets of telescopic devices 23 are installed on the lifting frame 22, and then the lifting frame 22 can drive the pallet to extend upward during the process of lifting upward, so that the pallet is lifted;

[0028] Specifically, in this structure, the telescopic device 23 is specifically composed of a cylinder and a clamping plate, wherein the output end of the cylinder is fixedly connected to the clamping plate, and the clamping plate can be driven to telescope through the cylinder;

[0029] The crankshaft assembly 26 is composed of a crankshaft and a crank block component. The crankshaft is connected to the crank block. When the crankshaft rotates, it can drive the crank block to rotate, thereby jacking up the jacking frame 22.

[0030] Working principle of this utility model:

[0031] When the above structure is used, the initial state is as shown in the attached Figure 1 As shown, when the tray is transported, the vegetable box tray is first placed on two conveyor chains 14 for transport. Figure 2 As shown, when the tray is transported, the driving motor 11 drives the motor chain 12 to operate, and drives the multiple driving rollers 13 to rotate inside the main frame 10, and the multiple driving rollers 13 drive the conveying chain 14 to operate, so that the vegetable box tray moves, thereby realizing the transportation of the tray;

[0032] When the pallet is transported to the position of the lifting device 2, it will accidentally hit the stop plate 3 and trigger the in-place inspection photoelectric 4. At this time, after the in-place inspection photoelectric 4 detects the signal that the pallet has arrived, the drive motor 11 stops running, so that the pallet can accurately reach the position of the lifting device 2. At the same time, during the transportation process, the two symmetrically arranged guide plates 5 can ensure the stability of the pallet during transportation and avoid the risk of the pallet falling during transportation.

[0033] When the vegetable box tray is transported to the position of the lifting device 2, the two sets of symmetrically distributed telescopic devices 23 are first extended and located at the bottom of the vegetable box tray to clamp the vegetable box tray, and the lifting motor 24 causes the lifting chain 25 to operate, and the lifting chain 25 drives the crankshafts of the multiple crankshaft assemblies 26 to rotate, and the rotation of the crankshaft drives the crank block to rise and lift the lifting frame 22, so that the two ends of the lifting frame 22 are guided upward by sliding inside the vertical track 21 through the guide wheels 6, and the two sets of telescopic devices 23 are installed on the lifting frame 22, and then the lifting frame 22 can drive the tray to extend upward during the process of lifting it upward, so that the tray is lifted;

[0034] In this way, the conveying device 1 conveys the next vegetable box tray to the jacking position, and the state is as shown in the attached figure. Figure 5 As shown, the lifting motor 24 continues to rotate, the vegetable box tray falls down and lands on the next vegetable box tray, the telescopic device 23 quickly retracts, the lifting motor 24 continues to rotate, the crankshaft block reaches the lowest position and stops, so that the two vegetable box trays are stacked together. This state is shown in the attached figure. Figure 6 shown.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
