First of all, it should be noted that the longitudinal direction in the present application refers to the transportation direction of the grain box plate 60 (the extension direction of the frame 50), and the transverse direction refers to the width direction of the frame 50; which is different from the prior art that adopts an assembly line for welding process. During welding, the grain box plate 60 is often difficult to fix and deviates during operation, which affects transportation and requires adjustment of the deviation in the middle, which reduces production efficiency. In addition, due to the large size of the grain box plate 60, it is more troublesome to adjust. The present application solves the above-mentioned defects in the prior art by setting up a dryer grain box plate 60 clamp mechanism, as follows:

[0040] The tray 40 is movably connected to the frame 50 in the longitudinal direction, and the tray 40 includes a placement portion 410 and an adjustment portion 420 arranged side by side in the transverse direction, the placement portion 410 is used to place the grain box plate 60, and the tray 40 is recessed to form the adjustment portion 420 extending in the longitudinal direction; the first support assembly 20 is connected to one side of the placement portion 410, the second support assembly 30 is connected to the tray 40 and arranged in the adjustment portion 420, and the second support assembly 30 is movably arranged in the transverse direction; the clamping mechanism 10 includes a plurality of transverse clamping assemblies 110 and a longitudinal clamping assemblies 120, a plurality of the transverse clamping assemblies 110 are arranged on the first support assembly 20 and the second support assembly 30 at intervals in the longitudinal direction, and the first support assembly 20 and the second support assembly 30 are both rotatably arranged toward the grain box plate 60; a plurality of the longitudinal clamping assemblies 120 are arranged on the placement portion 410 at intervals in the transverse direction, and the longitudinal clamping assembly 120 is rotatably arranged toward the grain box plate 60.

[0042] The tray 40 includes a placement portion 410 and an adjustment portion 420 which are arranged side by side in a transverse direction. The placement portion 410 is used for placing the grain box plate 60, and the adjustment portion 420 is used for allowing the second support assembly 30 to move laterally to adjust the spacing distance between the first support assembly 20 and the second support assembly 30, so as to adapt to grain box plates 60 of different sizes and improve the applicability of the entire mechanism. In order to ensure convenient movement, the adjustment portion 420 is formed as a recessed portion of the tray 40; in this way, the first support assembly 20 is connected to the placement portion 410, and the second support assembly 30 is movably arranged in the adjustment portion 420 in the transverse direction.

[0043] Furthermore, the clamping mechanism 10 includes a plurality of transverse clamping assemblies 110 and longitudinal clamping assemblies 120. The transverse clamping assemblies 110 are used to clamp the grain tank plate 60 in the transverse direction. Therefore, the first support assembly 20 and the second support assembly 30 are both provided with the transverse clamping assemblies 110 to ensure the clamping strength. In order to facilitate the disassembly and assembly of the grain tank plate 60, the first support assembly 20 and the second support assembly 30 are both rotatably arranged toward the grain tank plate 60, so as to drive the transverse clamping assembly 110 to rotate toward the grain tank plate 60, and rotate to the position of clamping the grain tank plate 60 when clamping is required. When the grain tank plate 60 needs to be replaced, it is rotated away from the grain tank plate 60 to make the transverse clamping assembly 110 lose the clamping effect; the longitudinal clamping assembly 120 is used to clamp the grain tank plate 60 in the longitudinal direction, and the longitudinal clamping assemblies 120 are arranged at both ends in the longitudinal direction to ensure the longitudinal clamping strength, and similarly, in order to ensure the convenience of disassembly and assembly, the longitudinal clamping assembly 120 itself is also rotatably arranged toward the grain tank plate 60 to be rotated and adjusted according to the usage, so as to cooperate with the transverse clamping assembly 110 so that the four ends of the grain tank plate 60 can ensure the clamping effect and ensure stable clamping.

[0045] It should be noted that the first driving component 210 is used to drive the first rotating shaft 220 to rotate, and the first bearing seat 230 is used for rotatably installing the first rotating shaft 220. The first shaft is used for installing multiple transverse clamping components 110, so that the multiple transverse clamping components 110 are arranged at intervals along the longitudinal direction. In this way, the first driving component 210 drives the first rotating shaft 220 to rotate toward the grain box plate 60, so that the transverse clamping components 110 installed on the first rotating shaft 220 rotate synchronously.

[0049] It should be noted that, similar to the first supporting assembly 20, the second driving assembly 310 is used to drive the second rotating shaft 320 to rotate, and the second bearing seat 330 is used for the rotatable installation of the second rotating shaft 320, and the second shaft is used for the installation of multiple transverse clamping assemblies 110, so that the multiple transverse clamping assemblies 110 are arranged at intervals along the longitudinal direction, so that the second driving assembly 310 drives the second rotating shaft 320 to rotate toward the grain box plate 60, so that the transverse clamping assemblies 110 installed on the second rotating shaft 320 rotate synchronously; and the transverse adjustment mechanism 340 is used to adjust the position of the second supporting assembly 30 in the transverse direction, and a transverse adjustment mechanism 340 is provided at each end of the second supporting assembly 30 to facilitate synchronization adjustment, wherein each transverse The adjustment mechanism 340 includes a transverse telescopic component 341, a transverse guide rail 342 and a mounting bracket 343. The transverse telescopic component 341 can be a hydraulic cylinder, a telescopic motor, etc., and its driving end can be set to be telescopically arranged along the transverse direction. The mounting bracket 343 is used for the installation of the second bearing seat 330, and the transverse guide rail 342 is used for the installation of the mounting bracket 343 and at the same time provides a guide for the movement of the mounting bracket 343. In addition to being connected to the transverse guide rail 342, one end of the mounting bracket 343 also extends to be connected to the driving part of the transverse telescopic component 341, so that the driving end of the transverse telescopic component 341 can be telescoped to drive the entire mounting bracket 343 to be adjusted transversely, and at the same time drive the second support component 30 located on the mounting bracket 343 to be adjusted transversely.

[0050] As a preferred embodiment of the present invention, the clamping mechanism 10 further includes two installation longitudinal rods 130 spaced apart in the transverse direction, the second support assembly 30 further includes a support longitudinal rod 350, and each of the transverse clamping assemblies 110 includes a transverse push seat 111 and a transverse clamping claw 112; wherein,

[0051] The two ends of the supporting longitudinal rod 350 are respectively connected to the two mounting brackets 343, the placing portion 410 and the supporting longitudinal rod 350 are connected to the mounting longitudinal rod 130, the transverse push seat 111 is connected to the supporting longitudinal rod 350 and is used to abut against the outer side of the grain tank plate 60, the transverse clamp 112 is L-shaped, and a through hole is opened on the horizontal section of the transverse clamp 112 to connect to the first rotating shaft 220 and the second rotating shaft 320, and the vertical section of the transverse clamp 112 is used to abut against the inner side of the grain tank plate 60.

[0052] It is worth noting that the clamping needs to adopt the method of clamping the inside and the outside at the same time to achieve the best clamping effect. Therefore, each of the transverse clamping components 110 includes a transverse push seat 111 and a transverse clamping claw 112. The support longitudinal rod 350 is used to fill part of the recessed space in the adjustment portion 420, and its two ends are respectively connected to the two mounting brackets 343 to facilitate the installation of the mounting longitudinal rod 130, and the mounting longitudinal rod 130 is used for the installation of the transverse push seat 111; it can be understood that the transverse clamping component 110 is installed on the first support component 20 and the second support component 30, so the first support component 20 and the second support component 30 are respectively provided with a corresponding support longitudinal rod 350, that is, the A supporting longitudinal rod 350 is provided directly below the first rotating shaft 220 and the second rotating shaft 320 for the installation of the transverse push seat 111, so that the transverse push seat 111 can abut against the outer side of the grain tank plate 60 to apply an inward extrusion thrust to the grain tank plate 60; and the transverse clamp 112 is correspondingly arranged above the transverse push seat 111, which is L-shaped, and a through hole is opened on the horizontal section of the transverse clamp 112 to facilitate the passage of the first rotating shaft 220 and the second rotating shaft 320, and the two sides of the through hole are straight to prevent the rotating shaft from rotating in the through hole. When clamping, the vertical section of the transverse clamp 112 is used to abut against the inner side of the grain tank plate 60, thereby cooperating with the transverse push seat 111 to achieve the clamping effect.

[0053] As a preferred embodiment of the present invention, the longitudinal clamping assembly 120 includes a longitudinal push seat 121, a longitudinal clamping jaw 122 and a third driving assembly 123, the longitudinal push seat 121 and the third driving assembly 123 are both connected to the placement portion 410, the longitudinal push seat 121 is used to abut against the outer side of the grain tank plate 60, the driving end of the third driving assembly 123 is connected to the longitudinal clamping jaw 122 to drive the longitudinal clamping jaw 122 to be rotatably arranged toward the grain tank plate 60, and the longitudinal clamping jaw 122 is used to abut against the inner side of the grain tank plate 60.

[0054] It is worth noting that, similar to the transverse clamping assembly 110, the longitudinal clamping also needs to adopt the method of clamping the inside and the outside at the same time to achieve the best clamping effect. Therefore, it includes a longitudinal push seat 121, a longitudinal clamping jaw 122 and a third driving assembly 123. The third driving assembly 123 is used to drive the longitudinal clamping jaw 122 to rotate toward the grain tank plate 60. It is connected to the placement portion 410, and the longitudinal push seat 121 is arranged between the third driving assembly 123 and the grain tank plate 60, so as to abut against the outside of the grain tank plate 60 to apply an inward extrusion thrust to the grain tank plate 60; the longitudinal clamping jaw 122 is connected to the driving end of the third driving assembly 123. When clamping, the third driving assembly 123 drives the longitudinal clamping jaw 122 to rotate toward the grain tank plate 60 to abut against the inside of the grain tank plate 60, thereby cooperating with the longitudinal push seat 121 to achieve the clamping effect.

[0055] Furthermore, each of the transverse clamping assemblies 110 also includes a gasket 113, the vertical section of the transverse clamping jaw 112 is connected to the horizontal section of the transverse clamping jaw 112 by bolts, and the gasket 113 is connected between the vertical section of the transverse clamping jaw 112 and the horizontal section of the clamping jaw.

[0056] It should be noted that the vertical section of the transverse clamp 112 is connected to the horizontal section of the transverse clamp 112 by bolts to facilitate adjustment of the spacing between the transverse clamp 112 and the side plate of the grain box plate 60, thereby adapting to the thickness of the side plates of different grain box plates 60. When the vertical section of the transverse clamp 112 and the horizontal section of the clamp cannot be closed after adjustment, the gasket 113 can be added to achieve a stable connection. The number of gaskets 113 can be multiple, and technical personnel in this field can choose according to specific circumstances.

[0057] Furthermore, the horizontal section of the transverse clamp 112 includes an upper horizontal section and a lower horizontal section, the bottom end of the upper horizontal section is recessed to form an upper arc-shaped hole, the top end of the lower horizontal section is recessed to form a lower arc-shaped hole, the upper arc-shaped hole and the lower arc-shaped hole are surrounded to form the through hole, and the upper horizontal section and the lower horizontal section are connected by bolts.

[0058] It should be understood that the horizontal section of the transverse clamp 112 is connected by bolts with an upper horizontal section and a lower horizontal section, so that the transverse horizontal position of the entire transverse clamp 112 can be adjusted. It should be noted that since some grain box plates 60 have transverse ribs, in order to avoid the conflict between the positions of some transverse clamps 112 and the transverse ribs during installation, which leads to the phenomenon of being unable to clamp, the transverse clamp 112 can be manually adjusted at this time, and the connection between the upper horizontal section and the lower horizontal section can be loosened by bolts to perform longitudinal movement. After adjustment, the upper horizontal section and the lower horizontal section are fixed by bolts to enclose the through hole for the rotating shaft to pass through.

[0060] It should be noted that the transverse telescopic motor 211 has a driving end that can be telescopically moved in the transverse direction, and the transverse rack 212 is used to cooperate with the transmission gear 213. Since the transmission gear 213 is connected to the first rotating shaft 220 and the second rotating shaft 320, the transverse rack 212 installed on the driving end of the transverse telescopic motor 211 drives the transmission gear 213 to rotate through meshing transmission when it moves synchronously, thereby achieving the effect of rotating the first rotating shaft 220 and the second rotating shaft 320; it can be understood that when rotating, the rotation directions of the first transmission gear 213 and the second transmission gear 213 are relative, so as to achieve the purpose of rotating toward the grain box plate 60.

[0061] Furthermore, the third driving assembly 123 includes a vertical telescopic motor 1231 and a vertical rack 1232, and the longitudinal clamp 122 has a connecting gear 1221 at one end close to the vertical rack 1232, and the connecting gear 1221 is hinged to the vertical telescopic motor 1231 through a pin shaft, and the vertical rack 1232 is connected to the driving end of the vertical telescopic motor 1231, and the connecting gear 1221 is meshed with the vertical rack 1232.
