Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain leveling technology, and in particular to a roller-type grain surface fine harrowing device. Background Technology
[0002] During the storage process, grain will form small piles. Even after the grain is initially leveled after the warehouse is full, these small piles will still leave pits and uneven marks on the grain surface. This not only affects the overall appearance of the grain surface, but also affects the ventilation of the grain pile.
[0003] The existing device moves the leveling component by moving the moving device to achieve fine raking of the grain. However, the existing device only raks the surface of the grain. Although it can avoid the situation where some grains piled up high will block the ventilation of nearby grains and affect the ventilation of nearby lower grains, the grains at the bottom have poor ventilation due to the multiple layers of grains above them. This results in the grains at the bottom having higher moisture content and higher temperature, which is not conducive to the storage of the grains. Utility Model Content
[0004] To address the aforementioned problems, the purpose of this utility model is to provide a roller-type grain surface fine raking and leveling device, which can improve the ventilation effect of grain while enhancing the aesthetic appearance of the grain surface.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A roller-type grain surface leveling device includes a pair of parallel and spaced track assemblies, a mounting platform fixed between the two track assemblies, a tilting and filtering mechanism mounted on the front of the mounting platform, a leveling mechanism mounted on the rear of the mounting platform, and a control mechanism for controlling the movement of the track assemblies. The tilting and filtering mechanism includes a pair of symmetrically hinged mounting plates on the left and right sides of the front of the mounting platform, a first rotating shaft rotatably mounted between the two mounting plates, a first motor fixed to the outer wall of any one of the mounting plates, a plurality of tilting blades spaced around the first rotating shaft and fixed to the outer side of the first rotating shaft, and detachably mounted between the two mounting plates and surrounding the first rotating shaft. The first rotating shaft has a C-shaped filter assembly on its rear side; the output shaft of the first motor passes through the mounting plate on the corresponding side and is fixedly connected to the first rotating shaft; the leveling mechanism includes a mounting seat fixed laterally on the rear side wall of the mounting platform, a second rotating shaft rotatably mounted laterally in the mounting seat, a second motor fixed to either the left or right outer side wall of the mounting seat and whose output shaft passes through the side wall and is fixedly connected to the second rotating shaft, a pair of guide plates symmetrically arranged on both sides of the rear of the mounting seat and sliding along the height direction of the mounting seat, and a flat plate whose front end is fixed to the second rotating shaft and whose two ends abut against the two guide plates respectively; the two guide plates gradually tilt inward from front to back on opposite sides.
[0007] More preferably, the C-type filter assembly includes a filter screen and a pair of flexible fixing strips fixed on both sides of the filter screen and detachably disposed inside the corresponding mounting plate.
[0008] More preferably, each of the two mounting plates has a limiting groove adapted to the flexible fixing strip on the side close to each other. The limiting groove has a plurality of slots, and the flexible fixing strip has a corresponding locking block at each end that cooperates with the slot to achieve fixation.
[0009] More preferably, a plurality of telescopic rods are evenly distributed along the length of the mounting base between the mounting base and the plate, and each telescopic rod is hinged at both ends to the mounting base and the plate, respectively.
[0010] More preferably, the flipping blade is arc-shaped and its two ends abut against the two mounting plates respectively.
[0011] This utility model has the following beneficial effects:
[0012] 1. This utility model uses a first motor to drive a first rotating shaft to rotate, thereby driving multiple rotating blades to rotate the grain, so that the grain at the bottom can be rotated to the top for ventilation, thereby improving the ventilation effect of the grain in the grain warehouse, thereby reducing the moisture content of the grain and lowering the temperature inside the grain.
[0013] 2. In the process of this utility model, after the front flipping and filtering mechanism flips the grain, the rear leveling mechanism levels the grain. On the one hand, this can improve the aesthetic effect of grain storage, and on the other hand, it can also avoid the situation where some grains are piled up too high and block the nearby grains, thus affecting the ventilation of the nearby lower grains.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] A roller-type grain surface leveling device includes a pair of parallel and spaced track assemblies 1, a mounting platform 2 fixed between the two track assemblies 1, a tilting and filtering mechanism 3 mounted on the front of the mounting platform 2, a leveling mechanism 4 mounted on the rear of the mounting platform 2, and a control mechanism for controlling the movement of the track assemblies 1. The tilting and filtering mechanism 3 includes a pair of symmetrically hinged mounting plates 31 on the left and right sides of the front of the mounting platform 2, a first rotating shaft 32 rotatably mounted between the two mounting plates 31, a first motor 33 fixed to the outer wall of any one of the mounting plates 31, a plurality of tilting blades 34 spaced around the first rotating shaft 32 and fixed to the outside of the first rotating shaft 32, and detachably mounted between the two mounting plates 31 and surrounding the plurality of first rotating shafts 32. The C-shaped filter assembly 35 is located on the rear side of shaft 32; the output shaft of the first motor 33 passes through the mounting plate 31 on the corresponding side and is fixedly connected to the first rotating shaft 32; the leveling mechanism 4 includes a mounting base 41 horizontally fixed on the rear side wall of the mounting platform 2, a second rotating shaft 42 rotatably mounted horizontally in the mounting base 41, a second motor 43 fixed on either the left or right side wall of the mounting base 41 and whose output shaft passes through the side wall and is fixedly connected to the second rotating shaft 42, a pair of guide plates 44 symmetrically arranged on both sides of the rear of the mounting base 41 and sliding along the height direction of the mounting base 41, and a leveling plate 45 whose front end is fixed to the second rotating shaft 42 and whose two ends abut against the two guide plates 44 respectively; the two guide plates 44 gradually tilt inward from front to back on opposite sides.
[0021] The first motor 33 drives the first rotating shaft 32 to rotate, thereby causing multiple flipping blades 34 to flip the grain, allowing the grain at the bottom to be flipped to the top for ventilation, thus improving the ventilation effect of the grain in the grain silo, thereby reducing the moisture and temperature inside the grain. During the movement of this device, after the flipping and filtering mechanism 3 at the front flips the grain, the leveling mechanism 4 at the rear levels the grain. This not only improves the aesthetics of the grain during storage, but also avoids the situation where some grains piled up too high will block the ventilation of nearby grains. Two inclined guide plates 44 can level the two sides of the grain, improving the aesthetics of the grain during storage.
[0022] As a possible implementation of this solution, preferably, the C-type filter assembly 35 includes a filter screen 351 and a pair of flexible fixing strips 352 fixed on both sides of the filter screen 351 and detachably disposed on the inner side of the corresponding mounting plate 31; through the cooperation of the mounting plate 31, the flexible fixing strips 352 and the filter screen 351, the filter screen 351 with the corresponding screening diameter can be selected according to the type of grain, thereby improving the accuracy of screening impurities in the grain.
[0023] As a possible implementation of this solution, preferably, each of the two mounting plates 31 has a limiting groove 311 adapted to the flexible fixing strip 352 on the side close to each other. The limiting groove 311 has a plurality of slots 312. The flexible fixing strip 352 has corresponding slots at both ends for fixing with the slots 312. By setting the limiting groove 311, the stability of the connection between the flexible fixing strip 352 and the mounting plate 31 can be improved, thereby reducing the possibility of the flexible fixing strip 352 shaking in the two mounting plates 31.
[0024] As a possible implementation of this solution, preferably, a plurality of telescopic rods 46 are evenly distributed along the length of the mounting base 41 between the mounting base 41 and the flat plate 45, and each telescopic rod 46 is hinged to the mounting base 41 and the flat plate 45 at both ends respectively; the arrangement of multiple telescopic rods 46 can improve the stability of the flat plate 45 when leveling the device.
[0025] As a possible implementation of this solution, preferably, the flipping blade 34 is arc-shaped and its two ends abut against the two mounting plates 31 respectively.
[0026] The working principle of this device is as follows:
[0027] When leveling grain, the two track assemblies are located on both sides of the grain. The grain is first turned by the turning blades 34, and then enters the C-type filter assembly 35 for filtration. Finally, the grain is leveled by the leveling plate 45 and the guide plate 44. When leveling the grain, the second motor 43 can be activated according to the thickness of the grain, so that the second rotating shaft 42 drives the leveling plate 45 to rotate, thereby adjusting the height of the lowest point of the leveling plate 45 from the ground to achieve leveling of grain of different thicknesses. At the same time, the two mounting plates 31 can be rotated to adjust the position of the turning filter mechanism 3 so that when the turning blades 34 rotate to the bottom, they abut against the ground. In this device, the mounting plate 31 and the mounting platform 2 are interference fit.
[0028] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
