Description

Technical Field

[0001] The utility model relates to the field of transportation or storage devices, in particular to a track-type flattening device. Background Art

[0002] When grain is stored in a warehouse, its surface becomes uneven. To facilitate storage and management and improve storage space utilization, the grain pile must be leveled—a process known as leveling. Currently, leveling is primarily done manually, which is time-consuming, labor-intensive, and inefficient. Furthermore, the large size of grain warehouses makes manual leveling ineffective. Furthermore, the leveling process generates excessive dust, which can harm workers' respiratory tracts.

[0003] Chinese patent application number 2019113011647 discloses a grain leveling machine, which includes tracks arranged horizontally along the inner walls of the two sides of the granary, with a bracket placed horizontally between the tracks. Track wheels that cooperate with the tracks are provided at both ends of the bracket, and at least one track wheel is driven by a motor. A leveling device that is slidably connected to the bracket is also provided on the bracket. The leveling device includes a leveling scraper and a hydraulic rod. The leveling scraper can be driven by the hydraulic rod to move up and down along the bracket to adjust the leveling height. This existing technology solves the practical problem of leveling grain during grain storage, but the above patent has the following problems when used: First, the width of the grain silo is relatively large, and the scraper that is consistent with the width of the grain silo encounters very large resistance during the actual leveling process. Unless an expensive, large-load motor is purchased, the scraper will be stuck and difficult to move; second, when the grain surface height in the granary changes with the rotation of the seasons and the type of stored grain, when the leveling scraper extends downward too long, the scraper overhang length is large, and the overturning moment of the bracket is large, which can easily cause the bracket to flip over and cause an accident. Therefore, this technology has not been promoted and applied in grain depots.

[0004] In summary, it is necessary to develop a higher strength leveling device that can meet the needs of grain storage. Utility Model Content

[0005] The purpose of the utility model is to provide a track-type leveling device which has high strength and can meet the leveling requirements of a grain depot.

[0006] To this end, a track-type flattening device of the present invention adopts the following technical solutions:

[0007] A rail-type leveling device comprises a first rail extending along the length direction of a granary, a base frame and a first driving part for driving the base frame to move along the first rail are provided between the first rails on both sides, a scraper seat and a second driving part for driving the scraper seat to slide are provided on the base frame, and a second rail is further provided on the granary, the second rail is parallel to the first rail and is located above the first rail, a bottom slider is slidably provided on the first rail, a third rail is fixed on the bottom slider, a surface slider is slidably provided in the third rail, the base frame is installed between the surface sliders on both sides, and a third driving part for driving the surface slider to slide along the third rail is provided;

[0008] Side sliders are slidably arranged on the second rails, and two groups of the side sliders are slidably arranged on each second rail. The side sliders include clamping parts, and the clamping parts are fixed together with the third rails through a detachable structure.

[0009] Furthermore, the cross-section of the surface slider is L-shaped, and it is movably installed in the third track through the guidance of the horizontal section, and the base frame is connected to its vertical section.

[0010] Furthermore, a dovetail groove 1 is provided on the third track, and the surface slider is clamped in the dovetail groove 1.

[0011] Furthermore, ridges are provided on both side surfaces of the third rail, and a slot having a shape matching that of the ridges is provided on the clamping portion, and the clamping portion is connected to the third rail via bolts.

[0012] Furthermore, bolt through holes are correspondingly provided on the bottom of the slot and the two side walls of the third track, and a recessed groove for completely embedding the bolt head is provided on the inner side of the third track around the bolt through holes.

[0013] Furthermore, the third driving part is an oil cylinder, the base portion of the oil cylinder is fixed on the third track, and the linear displacement output end is fixed on the surface slider.

[0014] Furthermore, the bottom slider is installed on the first track in a wrapped form from the outside, and grooves are provided on the upper and lower sides of the first track. The bottom slider includes claws that are adapted to the shape of the grooves to be clamped therein.

[0015] Furthermore, a roller is installed on the clamping claw, and when the bottom slider moves along the first track, the roller rolls in the groove.

[0016] Furthermore, a ball bearing is embedded on the side of the side slider that contacts the second track, and the ball bearing portion protrudes from the corresponding side of the side slider to roll along the second track.

[0017] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0018] When the height of the grain surface changes, the surface slider slides along the third track to adjust the height of the base frame, so that the height of the scraper seat installed on the base frame matches the height of the grain surface, thereby achieving the effect of leveling the grain bin. The overall height of the base frame across the entire width of the granary changes, and the overturning moment on the base frame is smaller than when only the scraper is raised or lowered. In addition, the upper end of the third track that bears the weight of the base frame is clamped and fixed by the side slider on the second track, and the lower end is fixed by the bottom slider on the first track. The force on the base frame will be evenly transmitted to the first track and the second track, making the leveling device of the utility model have a higher safety factor and a more stable structure.

DETAILED DESCRIPTION

[0027] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0029] Example 1 of a track-type warehouse unloading device of the utility model:

[0030] The specific structure of a track-type flattening device of the utility model is as follows Figures 1 to 5 As shown, the granary comprises a first rail 2 extending along the length of the granary 1. A bottom slider 3 is provided on the first rail 2, which can slide along the first rail. A third rail 4 is fixed to the bottom slider 3. A surface slider 6 is provided on the third rail 4, which can slide along the third rail. A base frame 7 is installed between the surface sliders 6 on both sides of the granary 1. A scraper seat 8 is provided on the base frame 7, which can be guided and moved along the third rail. When leveling operations are required, the leveling scraper is installed on the scraper seat 8 to perform the operations. The bottom slider 3 slides along the first guide rail via a first drive unit to adjust the position of the scraper in the length direction of the granary. The scraper seat 8 is guided and moved along the base frame 7 via a second drive unit to adjust the position of the scraper in the width direction of the granary 1. The surface slider 6 is guided and moved along the third rail 4 via a third drive unit to adjust the overall height of the base frame 7.

[0031] A second track 9 is provided along the length of the granary 1. The height of the first track 2 is consistent with the set grain loading line of the granary 1. The second track 9 is located above the first track 2. Side sliders 5 are provided on the second track 2 to slide along it. Each second track 2 is provided with two sets of side sliders 5, and the two sets of side sliders 5 are located on both sides of the bottom slider 3.

[0032] The first drive unit and the second drive unit are both drive motors. The way in which the drive motors drive the bottom slider 3 and the scraper seat 8 to move along a straight line is the same as the way in which the crane trolley and the trolley move in the prior art, and will not be described in detail in this application. The third drive unit is a hydraulic cylinder, the base of which is fixed to the upper end of the third rail 4 and the linear displacement output end is fixed to the surface slider 6. The hydraulic cylinder can not only adjust the height of the surface slider 6, but also lock the height of the surface slider 6 at the adjusted height during the liquidation operation. In order to achieve the fixation of the hydraulic cylinder, a base plate (not shown in the figure) is provided at the upper end of the third rail 4, and the base of the hydraulic cylinder is fixed to the base plate.

[0033] It is important to emphasize that the lower end of the third rail 4 is flush with the lower end of the first rail 2 to ensure that during normal grain storage, the third rail 4 is not buried by the grain, preventing surface corrosion and other defects. The surface slider 6 includes a horizontal section 61 and a vertical section 62. The horizontal section 61 is used to guide the movement of the third rail 4, and the vertical section 62 is used to connect to the base frame 7. The downward extension of the vertical section 62 allows the base frame 7 to be lowered to a position below the first rail 2 to meet the needs of closing the warehouse when the grain surface is low.

[0034] The first rail 2 has concave grooves 21 on both its upper and lower surfaces. The cross-sectional shape of the bottom slider 3 matches that of the first rail 2. The bottom slider 3 is clamped onto the first rail 2 from the outside, forming a wraparound shape. Two claws at the upper and lower ends of the bottom slider 3 extend into the grooves 21. This arrangement helps strengthen the connection between the bottom slider 3 and the first rail 2. Rollers are mounted on the claws. As the bottom slider 3 moves along the first rail 2, the rollers roll within the grooves 21, reducing frictional resistance. The rollers rotate within the grooves 21, driving the bottom slider 3 along the first rail 2.

[0035] The third rail 4 is provided with a dovetail groove 1 41, into which the surface slider 6 is mounted. The inner side of the second rail 9 is provided with a dovetail groove 2, into which the side slider 5 is engaged by a clamping block 51 and can move accordingly. The two side sliders 5 clamp the third rail 4 from both sides, evenly transferring the force applied to the third rail 4 to the first rail 2 and the second rail 9, ensuring the stability of the overall structure.

[0036] Specifically, ridges 42 are provided on both side surfaces of the third rail 4, and the side slider 5 includes a clamping block 52 protruding from the clamping block 51. The side of the clamping block 52 facing the surface slider 6 is also provided with a clamping groove 53 that matches the shape of the ridge 42. When the side slider 5 clamps the third rail 4 from both sides, the ridges 42 on both sides of the third rail 4 are both clamped into the corresponding clamping grooves 53 to limit the freedom of the third rail 4 and the side slider 6 in cooperation perpendicular to the wall of the granary 1.

[0037] Bolt holes are provided at the bottom of the slot 53 and on the ridge 42, corresponding to the holes provided. Once the ridge 42 is engaged with the slot 53, bolts are passed through the two holes to connect the side slider 5 to the third rail 4. It is important to note that a recessed groove 43 is provided on the inside of the third rail 4 at the opening of the bolt holes. The bolt heads are fully recessed in the recessed groove 43, so the installation of the bolts does not affect the sliding movement of the surface slider 6 within the third rail 4.

[0038] Ball bearings are embedded on both upper and lower sides of the side slider 5 to reduce the friction resistance when the side slider 5 moves along the first track 2 .

[0039] Embodiment 2 of a track-type warehouse unloading device of the present invention:

[0040] The difference between Example 2 and Example 1 is that, in the other embodiment, the bottom slider 3 and the first rail 2 are not provided with a cross-sectional engaging structure of an adaptive shape. Instead, only rollers are provided at the lower end of the bottom slider 3 to move along the upper surface of the first rail 2. The rigid base frame 7 connecting the bottom sliders 3 on both sides ensures that the bottom sliders 3 will move along the first rail 2 without derailing.
