[0022] In order to make the objectives, technical solutions and beneficial effects of the present invention more clear, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0023] like Figure 1-9As shown, the present invention provides a storage grain surface leveling device, which is installed on the top of a granary 4 and includes two door-shaped support frames 1, a leveling structure 2, and an automatic wooden board laying device 3; the two support frames 1 are respectively installed at the two ends of the top of the granary 4, and the leveling structure 2 and the automatic wooden board laying device 3 are respectively movably installed on a guide rod Ⅰ5 and a guide rod Ⅱ6 connected between the two support frames 1; the leveling structure 2 includes a mounting component Ⅰ21, a lifting mechanism Ⅰ22, and a leveling roller 23, both ends of the mounting component Ⅰ21 are slidably installed on the guide rod Ⅰ5, the lifting mechanism Ⅰ22 is installed at the bottom of the mounting component Ⅰ21, the leveling roller 23 is connected to the lifting end of the lifting mechanism Ⅰ22, and the mounting component Ⅰ21 is screwed The thread is installed on the screw rod Ⅰ7 installed between the two support frames 1, and the screw rod Ⅰ7 is connected to the motor Ⅰ71 installed on the support frame 1; the automatic wooden board laying device 3 includes an installation component Ⅱ31, a lifting mechanism Ⅱ32, and a wooden board delivery device 33; the two ends of the installation component Ⅱ31 are slidably installed on the guide rod Ⅱ6, and are threadedly connected to the screw rod Ⅱ8 installed between the two support frames 1, and the screw rod Ⅱ8 is connected to the motor Ⅱ81 installed on the support frame 1. The lifting mechanism Ⅱ32 is installed in a chute provided at the bottom of the installation component Ⅱ31 for horizontal movement, and the wooden board delivery device 33 is installed at the lifting end of the lifting mechanism Ⅱ32; the leveling roller 23 moves to scrape the grain surface flat, and the wooden boards are delivered onto the grain surface in sequence through the wooden board delivery device 33. After the grain is loaded into the granary 4, the motor Ⅰ71 is controlled to drive the screw rod Ⅰ7 to rotate, thereby pushing the installation component Ⅰ21 to slide on the guide rod Ⅰ5, so that the leveling roller 23 moves on the grain surface to scrape the grain surface flat. The lifting mechanism Ⅰ22 can be adjusted according to the height of the grain surface to gradually lower the leveling roller 23, so that the higher part of the grain surface is gradually scraped flat. The leveling roller 23 is controlled to move back and forth by controlling the square rotation of the motor Ⅰ71 to scrape the grain surface back and forth; after the grain surface is leveled, the leveling roller 23 is moved to the first layer of the granary 4, so as not to affect the laying of the wooden board. Motor Ⅱ81 drives screw rod Ⅱ8 to rotate, driving installation component Ⅱ31 to move on guide rod Ⅱ6. Lifting mechanism Ⅱ32 can adjust the height of wooden board delivery device 33 according to the height of grain surface. Wooden board delivery device 33 delivers a wooden board on grain surface, and then drives wooden board delivery device 33 forward for a distance through motor Ⅱ81, and then delivers the second wooden board, so that wooden boards are delivered in turn, forming a passage for easy walking. Lifting mechanism Ⅱ32 can move horizontally in the slide groove of installation component Ⅱ31, so that multiple wooden board passages can be laid on the grain surface.The present invention levels the grain surface by moving the leveling structure 2 back and forth on the grain surface, and the lifting mechanism Ⅰ22 is simultaneously arranged to adjust the height of the leveling roller 23, and can be flexibly adjusted according to the height of the grain surface, so as to level the grain surface. The grain surface is automatically leveled by the device, which improves the efficiency of leveling the grain surface and saves labor costs; the automatic wooden board laying device 3 can automatically lay the wooden board on the leveled grain surface, which is convenient for the staff to sample and inspect the grain on the wooden board, thereby avoiding the damage of the grain surface leveling again by manually laying the wooden board, and improving the quality of the grain surface leveling.

[0024] like Figure 2 As shown, the two ends of the leveling roller 23 are rotatably mounted on the two ends of the U-shaped fixed plate 231, and the middle part of the fixed plate 231 is connected to the lifting end of the lifting mechanism I 22. The leveling roller 23 is rotatably mounted on the fixed plate 231, so that the leveling roller 23 can roll when leveling the grain surface, which can reduce the friction of the leveling roller 23 on the rice, thereby reducing the damage to the rice.

[0025] like Figure 4 As shown, the plank placing device 33 comprises a mounting frame 331 with a U-shaped cross section and a plank placing structure 332. The top of the mounting frame 331 is connected to the lifting end of the lifting mechanism II 32. Two plank placing structures 332 are provided and are respectively installed on the side plates of the mounting frame 331. Both ends of multiple planks to be placed on the grain surface are placed on the plank placing structures 332, and then the planks are placed on the grain surface in sequence.

[0026] like Figure 4-6As shown, the wooden board placement structure 332 includes two rotating shafts 3321, two chains 3322, and a support plate 3323. The two rotating shafts 3321 are respectively installed in the strip holes opened on the lower end and the upper end of the side plate of the mounting frame 331. Two sprockets 3324 are arranged at both ends of the rotating shaft 3321. The two chains 3322 are respectively installed on the sprockets 3324 at both ends of the rotating shaft 3321. A plurality of support plates 3323 are evenly connected between the two chains 3322. The support plates 3323 are driven by the rotating shafts 3321 to move cyclically around the side plates of the mounting frame 331. The two ends of the wooden board are placed on the support plates 3323 of the two wooden board placement structures 332. When the planks are put in, the plank placement structure 332 is first moved to the top of the grain surface and to one side of the granary 4 through the lifting mechanism II32 and the screw rod II8, so that the planks can be laid from one side of the granary 4. When the planks are put in, the rotating shaft 3321 rotates, and the chain 3322 is driven to move through the sprocket 3324, thereby driving the support plate 3323 on the chain 3322 to move in a circular manner, and the rotating shaft 3321 on the two side plates of the mounting frame 331 rotates in the opposite direction, so that the support plates 3323 on both sides of the mounting frame 331 move downward at the same time, The wooden board is driven to move downward. When the support plate 3323 moves to the lower sprocket 3324 with the chain 3322, the support plate 3323 flips outward to the outside of the mounting frame 331, thereby automatically dropping the wooden board onto the grain surface. Then, the wooden board dropping device 33 is controlled by the screw rod Ⅱ8 to move a distance of the length of the wooden board, and the wooden boards are dropped onto the grain surface in turn, so that multiple wooden boards are connected into a walking channel, which is convenient for the staff to sample and test the grain on the wooden board channel, thereby improving the efficiency of wooden board laying and avoiding the damage to the grain surface caused by manual laying.

[0027] like Figure 7 As shown, the rear end of the mounting frame 331 is provided with a protective plate 333, and the protective plate 333 is provided with a double-axis motor 334. The two output shafts of the double-axis motor 334 are respectively connected to the rotating shafts 3321 of the two wooden board placement structures 332 through worm gear transmission. Before laying the wooden boards, the wooden boards need to be placed in the wooden board placement device 33 first, and multiple wooden boards are inserted into the support plates 3323 from one side of the mounting frame 331 in sequence, with the ends against the protective plate 333 at the rear end, so that the wooden boards are kept neat up and down, which is convenient for laying the wooden boards. The two ends of the wooden boards are respectively placed on the support plates 3323 at the two ends, and the rotating shaft 3321 is driven to rotate by the double-axis motor 334, so that the chain 3322 drives the support plate 3323 to move, and the wooden boards are placed and laid.

[0028] like Figure 7As shown, the worm screw directions on the two output shafts of the dual-axis motor 334 are opposite. The opposite worm screw directions on the two output shafts can make the rotating shafts 3321 on both sides of the mounting frame 331 rotate in opposite directions, thereby making the support plates 3323 at both ends of the support wooden board move in the same direction.

[0029] like Figure 8 As shown, the upper end of the lifting mechanism II32 is threadedly mounted on the screw rod III9 provided in the slideway; the screw rod III9 is ​​in transmission connection with the motor III91 provided at the end of the mounting component II31, and the lifting mechanism II32 moves transversely in the slideway under the drive of the screw rod III9. The wooden board delivery device 33 moves transversely on the mounting component II31, so that multiple wooden board channels can be laid on the grain surface, and the screw rod III9 is ​​driven to rotate by the motor III91, so that the lifting mechanism II32 drives the wooden board delivery device 33 to move transversely in the slideway.

[0030] like Fig. 9 As shown, the lifting mechanism I22 has the same structure as the lifting mechanism II32, including a fixed block 221, a square sleeve 222, a screw rod IV223, a square lifting rod 224, and a motor IV225. The fixed block 221 of the lifting mechanism I22 is fixedly connected to the bottom of the mounting component I21, and the fixed block 221 of the lifting mechanism II32 is threadedly mounted on the screw rod III9 set in the bottom slide groove of the mounting component II31. The square sleeve 222 is connected to the bottom of the fixed block 221; the screw rod IV223 is installed in the square sleeve 222 and is transmission-connected to the motor IV225. The motor IV225 is installed in the mounting hole 226 set on the fixed block 221. The square lifting rod 224 is sleeved in the square sleeve 222 and is threadedly connected to the screw rod IV223; the fixed plate 231 or the mounting frame 331 is connected to the lower end of the square lifting rod 224. Motor IV225 drives screw rod IV223 to rotate, and screw rod IV223 and square lifting rod 224 rotate threadedly, so that the square lifting rod moves up and down in the square sleeve 222 driven by screw rod IV223, thereby driving the leveling roller 23 or the wooden board delivery device 33 to move up and down, which is convenient for scraping the grain surface and laying the wooden boards.

[0031] Working process: After the grain is loaded into the granary 4, the motor Ⅰ71 is controlled to drive the screw rod Ⅰ7 to rotate, thereby pushing the installation component Ⅰ21 to slide on the guide rod Ⅰ5, so that the leveling roller 23 moves on the grain surface to scrape the grain surface flat. The lifting mechanism Ⅰ22 can be adjusted according to the height of the grain surface to gradually lower the leveling roller 23, so that the higher part of the grain surface is gradually scraped flat. The leveling roller 23 is controlled to move back and forth by controlling the square rotation of the motor Ⅰ71 to scrape the grain surface back and forth; after the grain surface is leveled, the leveling roller 23 is moved to the first layer of the granary 4, so as not to affect the laying of the wooden board. Motor Ⅱ81 drives screw rod Ⅱ8 to rotate, driving installation component Ⅱ31 to move on guide rod Ⅱ6. Lifting mechanism Ⅱ32 can adjust the height of wooden board delivery device 33 according to the height of grain surface. Wooden board delivery device 33 delivers a wooden board on grain surface, and then drives wooden board delivery device 33 forward for a distance through motor Ⅱ81, and then delivers the second wooden board, so that wooden boards are delivered in turn, forming a passage for easy walking. Lifting mechanism Ⅱ32 can move horizontally in the slide groove of installation component Ⅱ31, so that multiple wooden board passages can be laid on the grain surface.

[0032] When the planks are put in, the plank placement structure 332 is first moved to the top of the grain surface and to one side of the granary 4 through the lifting mechanism II32 and the screw rod II8, so that the planks can be laid from one side of the granary 4. When the planks are put in, the rotating shaft 3321 rotates, and the chain 3322 is driven to move through the sprocket 3324, thereby driving the support plate 3323 on the chain 3322 to move in a circular manner, and the rotating shaft 3321 on the two side plates of the mounting frame 331 rotates in the opposite direction, so that the support plates 3323 on both sides of the mounting frame 331 move downward at the same time, The wooden board is driven to move downward. When the support plate 3323 moves to the lower sprocket 3324 with the chain 3322, the support plate 3323 flips outward to the outside of the mounting frame 331, thereby automatically dropping the wooden board onto the grain surface. Then, the wooden board dropping device 33 is controlled by the screw rod Ⅱ8 to move a distance of the length of the wooden board, and the wooden boards are dropped onto the grain surface in turn, so that multiple wooden boards are connected into a walking channel, which is convenient for the staff to sample and test the grain on the wooden board channel, thereby improving the efficiency of wooden board laying and avoiding the damage to the grain surface caused by manual laying.
