A synchronous belt 220 sleeved on two synchronous wheels 210, two synchronous brackets 230 respectively connected to the top and bottom of the synchronous belt 220, and a guide shaft 240 parallel to the moving direction of the synchronous belt 220, both ends of the guide shaft 240 are respectively connected to the tray 110, the two synchronous brackets 230 are respectively connected to linear bearing seats 250 slidably sleeved on the guide shaft 240, and the two linear bearing seats 250 are respectively connected to the corresponding sides of the two sliding doors 140; buffer rings 260 are respectively sleeved on both ends of the guide shaft 240. A spring 270 is connected between the linear bearing seat 250 corresponding to a synchronization bracket 230 in each synchronization mechanism and the tray 110. The tray 110 is connected to a mounting seat 280 corresponding to the spring 270. The mounting seat 280 is threadedly connected to a spring adjustment screw 290 that can move axially. The spring 270 is connected to the corresponding spring adjustment screw 290. A locking nut 291 is connected to the spring adjustment screw 290 through a threaded sleeve. The spring 270 is used to make the two corresponding synchronization brackets 230 move in the opposite direction and reset after moving away from each other, so that the two sliding doors 140 move toward each other to close the bottom of the hopper 130.

[0035] The unloading assembly 300 includes an unloading bracket 310, a horizontal push cylinder 320 connected to the unloading bracket 310, a vertical push cylinder 330 connected to the cylinder rod of the horizontal push cylinder 320, and a hook 340 connected to the cylinder rod of the vertical push cylinder 330. The horizontal push cylinder 320 is used to drive the vertical push cylinder 330 to move toward or away from the handle 150, and the vertical push cylinder 330 is used to drive the hook 340 to pass through or escape from the handle 150.

[0036] The horizontal push cylinder 320 is connected to two first sensors 350 spaced apart along its length direction, and the vertical push cylinder 330 is connected to a first detection plate 360. When the cylinder rod of the horizontal push cylinder 320 is extended or retracted, the first detection plate 360 ​​is disengaged from or moved to the sensing range of each first sensor 350. The vertical push cylinder 330 is connected to two second sensors 370 spaced apart along the height direction, and the hook 340 is connected to a second detection plate 380. When the cylinder rod of the vertical push cylinder 330 is extended or retracted, the second detection plate 380 is disengaged from or moved to the sensing range of each second sensor 370. The top of the unloading bracket 310 is connected to two third sensors 400 located above the hopper 130 through a material unloading sensing bracket 390. The two third sensors 400 are spaced apart along the width direction of the pallet 110, and the third sensors 400 are used to detect the height of the material in the hopper 130. In this embodiment, the front end and the rear end of the pallet 110 refer to Figure 1 The left and right ends of the .

[0037] The working principle of the tray-type circulating conveying bucket device provided in the embodiment of the present application is: placing the material in the hopper 130 in the conveying bucket assembly 100 and supporting it with a pair of sliding doors 140, and using the tray 110 in the conveying bucket assembly 100 to support the hopper 130 and the material, using the conveying mechanism to convey the conveying bucket assembly 100 to support the material along a fixed moving track to the end point of the moving track, and fixing the unloading assembly 300 in advance on one side of the moving track end point of the conveying bucket assembly 100 to perform unloading operations;

[0038] When the conveying mechanism conveys the conveying bucket assembly 100 to the end point of the moving trajectory, the horizontal push cylinder 320 of the unloading assembly 300 is arranged opposite to the handle 150 of the conveying bucket assembly 100. At this time, the cylinder rod of the horizontal push cylinder 320 is controlled to extend, so that the vertical push cylinder 330 and the hook 340 connected to the cylinder rod of the horizontal push cylinder 320 are moved to above the handle 150 of the conveying bucket assembly 100. Then, the cylinder rod of the vertical push cylinder 330 is controlled to extend, so that the hook 340 connected to the cylinder rod of the vertical push cylinder 330 passes through the handle 150 from top to bottom, so that the cylinder rod of the horizontal push cylinder 320 can be controlled to contract and drive the cylinder rod of the vertical push cylinder 330 to move upward. The cylinder rod and the hook 340 move in opposite directions to drive the handle 150 to move, so that the handle 150 drives the correspondingly connected sliding door 140 to move in a direction away from the other sliding door 140. When the sliding door 140 moves, the other sliding door 140 is driven to move through the opening and closing follower assembly 200. Specifically, when the sliding door 140 connected to the handle 150 moves in a direction away from the other sliding door 140, the two linear bearing seats 250 and the synchronous brackets 230 correspondingly connected in the synchronous mechanism on both sides of the tray 110 are driven to move and stretch the two springs 270, so that the synchronous brackets 230 in the two synchronous mechanisms drive the two corresponding synchronous belts 220 to move in a synchronous manner. The synchronous belt 220 rotates clockwise, and then the synchronous bracket 230 and the linear bearing seat 250 corresponding to the two sides of the other sliding door 140 are driven to move through the clockwise rotating synchronous belt 220, thereby driving the other sliding door 140 to move, so that the two sliding doors 140 move synchronously in the direction away from each other to connect the hopper 130 and the discharge port 120, so that the material placed in the hopper 130 falls through the discharge port 120 provided in the middle of the tray 110 to complete the material conveying operation, and then the cylinder rod of the vertical push cylinder 330 can be controlled to contract to drive the hook 340 to move in the opposite direction and rise to separate from the handle 150. At this time, the two stretched springs 270 drive the two The correspondingly connected linear bearing seats 250 and synchronous brackets 230 in the synchronous mechanism move in the opposite direction and reset, so that the two synchronous brackets 230 respectively drive the synchronous belts 220 in the two synchronous mechanisms to rotate counterclockwise and reset, and then drive the two synchronous brackets 230 respectively connected to the top and bottom of the synchronous belt 220 to move toward each other, so that the linear bearing seats 250 and the two sliding doors 140 connected to the two synchronous brackets 230 move toward each other to the bottom of the closed hopper 130, and the conveying mechanism can be used to convey the conveying bucket assembly 100 to the starting point of the moving trajectory to re-accommodate and support the material for the next material conveying.

[0039] Among them, the top front end and the rear end of the tray 110 are respectively provided with sliding limit frames 180 for limiting the sliding routes of the two sliding doors 140, and the sliding limit frames 180 are provided with sliding holes 190 for the sliding doors 140 to pass through. When the two sliding doors 140 move in the direction of moving away from each other, they respectively pass through the sliding holes 190 on the sliding limit frames 180 at the top front end and the rear end of the tray 110, so that the positions of the two sliding doors 140 are limited by the sliding holes 190 on the two sliding limit frames 180 to ensure that the two sliding doors 140 stably move in the direction of moving away from or approaching each other.

[0040] Buffer rings 260 are respectively sleeved on both ends of the guide shaft 240, and the buffer rings 260 sleeved on both ends of the guide shaft 240 can be used to buffer and block the two linear bearing seats 250 moving along the guide shaft 240. The tray 110 is connected to a mounting seat 280 corresponding to the spring 270, and the mounting seat 280 is threadedly connected to a spring adjustment screw 290 that can move axially. The spring 270 is connected to the corresponding spring adjustment screw 290, and a locking nut 291 is threadedly sleeved on the spring adjustment screw 290, which can facilitate the operator to rotate the spring adjustment screw 290 to move it axially to adjust the distance from the linear bearing seat 250, thereby adjusting the tension of the spring 270 to ensure the stable reset of the stretched and moving linear bearing seat 250.

[0041] The transverse pushing cylinder 320 is connected to two first sensors 350 arranged at intervals along its length direction, and the vertical pushing cylinder 330 is connected to a first detection plate 360. When the cylinder rod of the transverse pushing cylinder 320 is extended or retracted, the first detection plate 360 ​​is disengaged or moved to the sensing range of each first sensor 350, so that the first sensor 350 is used to detect the position of the first detection plate 360 ​​that moves with the vertical pushing cylinder 330 to confirm that the cylinder rod of the transverse pushing cylinder 320 pushes the vertical pushing cylinder 330 to extend and retract to the preset position above the handle 150.

[0042] The vertical push cylinder 330 is connected to two second sensors 370 arranged at intervals along the height direction, and the hook hand 340 is connected to a second detection plate 380. When the cylinder rod of the vertical push cylinder 330 is extended or retracted, the second detection plate 380 is disengaged or moved to the sensing range of each second sensor 370, so that the second sensor 370 is used to detect the position of the second detection plate 380 that moves with the hook hand 340 to confirm that the cylinder rod of the vertical push cylinder 330 pushes the hook hand 340 to extend and retract to pass through the handle 150.

[0043] The top of the unloading bracket 310 is connected to two third sensors 400 located above the hopper 130 through the unloading sensing bracket 390. The two third sensors 400 are arranged at intervals along the width direction of the tray 110. The third sensor 400 is used to detect the height of the material in the hopper 130, so as to use the third sensor 400 to detect whether the material in the hopper 130 falls through the unloading port 120 provided in the middle of the tray 110 to complete the material conveying operation.

[0044] In other optional embodiments, the spring 270 may not be provided, and the handle 150 may be made annular. In this case, when the cylinder rod of the vertical push cylinder 330 is extended, the hook 340 is lowered and passes through the handle 150, and the cylinder rod of the horizontal push cylinder 320 is extended and retracted to drive the cylinder rod of the vertical push cylinder 330 and the hook 340 to move back and forth, driving the handle 150 and the corresponding sliding door 140 to move, and through the opening and closing follower assembly 200, it is ensured that the two sliding doors 140 stably move synchronously in the direction of moving away from or approaching each other to open or close the bottom of the hopper 130.

[0045] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
