Description

Technical Field

[0001] The invention relates to a warehouse closing device, in particular to a novel track type warehouse closing device. Background Art

[0002] At present, most of the grain storage closing work in my country is done manually, which is not only slow, labor-intensive, but also difficult to ensure the quality of closing. Especially for grain piles with large height differences, a closing machine is needed to achieve closing.

[0003] A Chinese patent with application number 2019113011647 discloses a grain flattening machine, including two tracks installed on both sides of the inner wall of a granary and a bottom plate located on the inner side of the track, track wheels are installed on both sides of the bottom plate, a motor driving the track wheels to rotate along the track is installed on the bottom plate, and a flattening plate is provided at the lower end of the bottom plate. The flattening operation is realized by driving the flattening plate to move along the length direction of the granary by the bottom plate moving along the track, and the flattening plate can be driven by a hydraulic rod to move up and down relative to the track to adjust the flattening height. In this prior art document, in order to avoid the flattening device being difficult to move due to insufficient friction, a threaded rod and a propulsion motor are also provided between the bottom plate and one end wall in the length direction of the granary to provide additional power for the base to move.

[0004] The above-mentioned shortcomings of the prior art are: first, the width of the granary is relatively large, and the flattening plate that is consistent with the width of the granary is subject to very large resistance during the actual flattening process; second, when the grain surface height in the granary changes with the rotation of seasons and the different types of stored grains, when the flattening plate extends downward too long, the overhang length of the flattening plate is relatively large, and the overturning moment of the bottom plate is relatively large, which can easily cause the bottom plate to flip over and cause an accident; third, the threaded rod can only rotate along its own axis, but cannot be translated to the corners of the granary. The threaded rod placed in the middle of the granary divides the internal space of the granary in the length direction. The work of grain storage, grain out of the warehouse, aisle plate placement and grain surface processing will be blocked by the threaded rod, which is very inconvenient; fourth, the granary is relatively long, and the processing and design of the threaded rod also has difficulties.

[0015] Furthermore, the floating connection structure is located in the middle of the chassis; three sides of the anti-slip section are provided with grooves for the corresponding parts of the elastic pad to be embedded; and a tension spring is provided between the chassis and the vehicle body.

[0016] Furthermore, the trolley is a tracked trolley, and two groups of front and rear rollers are arranged at the lower end of the chassis. The driving motor is used to drive one group of rollers to rotate, and a track for transmitting power is arranged between the two groups of rollers.

[0017] Furthermore, grooves 1 are provided on both sides of the base frame, and transverse track wheels are installed on both sides of the scraper seat, and the transverse track wheels are embedded in the grooves 1.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] 1. In the present invention, a second track is arranged above the first track. When the height of the grain surface in the granary changes, the chassis moves up and down as a whole to maintain the height between the scraper seat and the grain surface substantially unchanged. Then, the first track, the second track, and the third track are connected as a whole using side sliders. The force of the scraper seat will be evenly transmitted to the first track, the second track, and the third track. The height of the chassis across the full width of the granary changes as a whole. Compared with the case where only the scraper is raised and lowered, the overturning moment of the chassis is smaller. In addition, the force of the chassis is evenly transmitted to the first track and the second track, which makes the safety factor of the present invention higher and the structure more stable.

[0021] 2. The trolley is only used to push or pull the scraper seat and provide auxiliary power for the movement of the scraper seat. The position of the warehouse closing is adjusted by the lateral and longitudinal movement of the scraper seat along the track. It can not only ensure that there is no dead angle in the warehouse closing work in the granary, but also provide sufficient walking power for the movement of the scraper seat to avoid the scraper seat being unable to move due to insufficient power. At the same time, the trolley that is only used to provide auxiliary power has a simpler structure, smaller size and weight, and leaves shallow rutting marks when walking along the grain surface. Because it does not need to turn, it also avoids leaving deep turning marks on the grain surface.

[0022] 3. The trolley moves along the track. When it is not necessary to level the silo, the scraper seat can be pushed to a corner of the silo, and the trolley will also move to the corner of the silo, occupying less space. The ball joint between the trolley and the scraper seat can also be removed. Therefore, the present invention also has the effect of not hindering the storage and unloading of grain, the placement of the walkway board and the grain surface processing.

[0023] 4. When the trolley moves along the grain surface, the body of the trolley floats relative to the chassis. Therefore, when the trolley moves on the uneven grain surface, the power of the trolley can still be transmitted to the scraper seat through the ball joint, without affecting its function of providing auxiliary power.

[0024] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] Embodiments of the present invention are described in detail below, 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 be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Embodiment 1 of a novel track-type warehouse closing device of the present invention:

[0038] The specific structure of a novel track type warehouse unwinding device of the present invention is as follows: Figures 1 to 7As shown, it includes a first track 2 extending along the length direction of the granary 1, a bottom slider 3 that can slide along the first track 2 is provided, a third track 4 that can move up and down is installed on the bottom slider 3, a surface slider 5 that can slide along the third track 4 is provided, and a bottom frame 7 is installed between the surface sliders 5 on both sides of the granary 1, and a scraper seat 9 that can move along the bottom frame 7 is provided. A new type of track-type flattening device of the present invention also includes a crawler trolley 6 that can travel along the grain surface. The crawler trolley 6 is connected to the scraper seat 9 for force transmission. The first driving unit drives the bottom slider 3 to slide along the first guide rail 2 to adjust the position of the scraper seat 9 in the length direction of the granary, and the first driving unit is the main power mechanism for driving the bottom frame 7 to move. The second driving unit drives the scraper seat 9 to move along the bottom frame 7 to adjust the position of the scraper seat 9 in the width direction of the granary 1, and the second driving unit plays a role in adjusting the flattening width range. The third driving unit is used to drive the surface slider 5 to move along the third track 4 to adjust the overall height of the bottom frame 7 when the height of the third track 4 remains unchanged. When it is necessary to carry out a flattening operation, a flattening scraper is installed on the scraper seat 9 to carry out the operation. The crawler trolley 6 provides additional power for the movement of the scraper seat 9, and the scraper seat 9 guides the crawler trolley 6.

[0039] In this embodiment, grooves 71 are provided on both sides of the base frame 7, and transverse track wheels 91 are installed on both sides of the scraper seat 9, and the transverse track wheels 91 are embedded in the grooves 71. In this form, the scraper seat 9 is suspended below the base frame 7, and there is a guiding matching relationship between the scraper seat 9 and the base frame 7.

[0040] A second track 8 is also provided along the length direction of the granary 1. The height of the first track 2 is consistent with the grain loading line of the granary 1 to ensure that the first track 2 will not be buried by the grain. The second track 8 is located above the first track 2 to assist in fixing. The second track 8 is provided with side sliders 10 that can slide along it. Each second track 8 is provided with two sets of side sliders 10 and the two sets of side sliders 10 are respectively located on both sides of the bottom slider 3. The side sliders 10 are used to clamp the third track 4 to connect the first track 2, the second track 8 and the third track 4 as a whole. In other embodiments, the side sliders 10 can also be provided on the first track 2 and the second track 8 at the same time to further increase the structural strength.

[0041] In this embodiment, a dovetail groove 1 41 is provided on the third rail 4, and the surface slider 5 is clamped in the dovetail groove 1 41. A dovetail groove 2 81 is provided on the inner side of the second rail 8, and the side slider 10 is clamped in the dovetail groove 2 81 through a clamping block 101 and can move therewith. The two side sliders 10 clamp the third rail 4 from both sides to evenly transfer the force of the third rail 4 to the first rail 2 and the second rail 8, thereby ensuring the stability of the overall structure.

[0042] To ensure that the two side sliders 10 can clamp the third rail 4, ridges 42 are provided on both side surfaces of the third rail 4. The side slider 10 includes a clamping block 102 protruding outward from the clamping block 101. The clamping block 102 is also provided with a clamping groove 103 that matches the shape of the ridge 42 on the side facing the surface slider 5. When the side slider 10 clamps the third rail 4 from both sides, the ridges 42 on both sides of the third rail 4 are all inserted into the corresponding clamping grooves 103 to limit the freedom of the third rail 4 and the side slider 10 in cooperation with each other in a direction perpendicular to the wall of the granary 1.

[0043] Bolt holes are provided at the bottom of the slot 103 and on the ridge 42. After the ridge 42 is inserted into the slot 103, bolts are passed through the two bolt holes to connect the side slider 10 and the third track 4. It should be emphasized that a sink groove is provided at the inner side of the third track 4 at the opening of the bolt hole, and the head of the bolt is completely sunk into the sink groove, so the installation of the bolt will not affect the sliding of the surface slider 5 in the third track 4.

[0044] Ball bearings are embedded on both upper and lower side surfaces of the side slider 10 to reduce the friction resistance when the side slider 10 moves along the second track 8 .

[0045] The third track 4 further includes a limit end 43 at the lower end, and the limit end 43 can limit the extreme position of the surface slider 5 sliding downward to prevent the surface slider 5 from separating from the third track 4.

[0046] In this embodiment, groove 2 is provided on the lower end surface of the first track 2 and the upper end surface of the second track 8. The bottom slider 3 is relatively long, and the two claws 31 at its upper and lower ends extend into the corresponding groove 2. This form is conducive to increasing the bonding strength of the bottom slider 3, the first track 2, and the second track 8. A roller is installed on the claw 31. When the bottom slider 3 moves along the first track 2, the roller rolls in the groove 2 to reduce the friction resistance of walking. A common driving motor is used as the first driving part to drive the roller to rotate in the groove 21, and the bottom slider 3 is driven to move along the first track 2 and the second track 8 through the rotation of the roller. Under this structural form, the power transmitted by the crawler trolley 6 will push the scraper seat 9 and the base frame 7 to translate, and the scraper seat 9 will not flip or twist.

[0047] The purpose of the third track 4 being able to move up and down is to meet the need for closing the warehouse when the grain surface is low, and at the same time to prevent the grain from burying the third track 4 when the grain surface is high, making it difficult for the bottom frame 7 to slide along the length direction of the granary 1. The up and down movement of the third track 4 relative to the bottom slider 3 is driven by a cylinder or an electric push rod. After being adjusted in place, the relative position between the third track 4 and the bottom slider 3 is locked to prevent the third track 4 from accidentally sliding down. After the third track 4 is adjusted in place, the side slider 10 is connected to the third track 4 with bolts, which further enhances the stability of the third track 4 to maintain a constant height and makes the overall structure more reliable.

[0048] A dovetail groove 3 is provided on the outer side of the bottom slider 3, and a dovetail-shaped block of a matching shape is provided on the back of the third track 4. The third track 4 is guided and moved relative to the bottom slider 3 through the dovetail-shaped guiding matching structure. In this embodiment, a toothed structure 32 is provided at the bottom of the dovetail groove 3 on the bottom slider 3, and a lock tongue 14 is provided on the back of the dovetail-shaped block on the third track 4. The lock tongue 14 can be inserted into the toothed structure 32 to prevent the third track 4 from sliding uncontrolled relative to the bottom slider 3. In this application, the lock tongue 14 is an electromagnetic lock tongue, which retracts into the third track 4 when powered on so as not to affect the lifting and lowering of the third track 4 relative to the bottom slider 3, and extends out of the third track 4 when powered off to get stuck between two adjacent teeth of the toothed structure 32. The mechanism of extending out when powered off enables the lock tongue of the present invention to maintain a locked state when the power is accidentally cut off without causing the third track 4 to accidentally fall.

[0049] To ensure safety, a plurality of locking tongues 14 are provided on the back of the third track 14, and the plurality of locking tongues 14 are all located in the middle of the locking tongue 14, so when the third track 14 rises to the upper limit position and falls to the lower limit position, the plurality of locking tongues 14 can be inserted into the corresponding teeth to play a locking role. In other embodiments, a bolt structure can also be used to replace the locking structure composed of the locking tongue 14 and the toothed structure 32.

[0050] In this embodiment, there is no locking mechanism between the surface slider 5 and the third rail 4 that can lock the positions of the two. Instead, the height of the surface slider 5 is maintained by the holding capacity of the third driving mechanism. This is because, under normal circumstances, when the height of the bottom frame 7 needs to be adjusted, it is achieved by adjusting the height of the third rail 4. During this process, the lower end of the surface slider 5 is always supported by the limit end 43. Only in the early stage of closing the warehouse, when the height difference of the grain surface is particularly large, it is necessary to lift the surface slider 5 and the bottom frame 7 through the third driving mechanism to ensure that the bottom frame 7 can smoothly exceed the high point of the grain surface to reach the other end of the grain silo to connect with the crawler trolley 6 located at the other end of the grain silo.

[0051] In this embodiment, the third driving mechanism is a hydraulic cylinder or an electric push rod, whose linear displacement output end is fixed on the surface slider 5, and the housing part is fixed on the upper end of the third track 4. In this embodiment, in order to clearly illustrate the shape and structure of the third track 4, this part is not shown.

[0052] The crawler trolley 6 is connected to the scraper seat 9 through a ball joint 11. The ball shell of the ball joint 11 is fixed to the front end of the vehicle body, and the ball head rod is hinged to the scraper seat 9. Therefore, the crawler trolley 6 can push the scraper seat 9 and pull the scraper seat 9. When the angle between the vehicle body and the scraper seat 9 changes, power can be transmitted smoothly.

[0053] The crawler trolley 6 includes a chassis 61, a body 62, rollers 63, a drive motor 64 and a crawler track 65, wherein the rollers 63 are rotatably mounted below the chassis 61, the body 62 is floatingly arranged above the chassis 61, the crawler track 65 is wound between the front and rear groups of rollers 63 to increase the contact area between the crawler trolley 6 and the grain surface, and the drive motor 64 is used to drive the rollers 63 to rotate. The drive motor 64 transmits power to the rollers 63 through a gear structure (not shown in the figure). The ball shell part of the ball joint 11 is fixed to the front end of the body 62, and the ball head rod is hinged on the scraper seat 9. It should be emphasized that when adjusting the height of the chassis 7, the ball joint 11 between the body 62 and the scraper seat 9 needs to be disassembled first, so the ball shell part and the body 62 are detachably connected or the ball head rod and the scraper seat 9 are detachably connected. The form of realizing the detachable connection can be a bolt connection or other detachable connection forms in the prior art.

[0054] A floating connection structure 13 is provided between the chassis 61 and the vehicle body 62. The floating connection structure 13 includes a guide rod 131 fixed above the chassis 61 and a guide column 132 fixed below the vehicle body 62. The guide rod 131 is inserted into the guide column 132 along the axis. A protruding section 133 protrudes outward from the upper end of the guide rod 131. The guide column 132 includes an anti-slip section 134. When the vehicle body 62 rises relative to the chassis 61, the anti-slip section 134 can cooperate with the protruding section 133 to prevent the vehicle body 62 from being separated from the chassis 61. An elastic pad 135 is sleeved on the inner circumference of the anti-slip section 134. The three sides of the anti-slip section 134 are provided with grooves 136 for the corresponding parts of the elastic pad 135 to be embedded to increase the bonding strength between the elastic pad 135 and the anti-slip section 134.

[0055] In this embodiment, the guide rod 131 and the guide column 132 are both fixed to the corresponding base body by bolts and flange structures.

[0056] The inner diameter of the elastic pad 135 matches the size of the guide rod 131, but the elastic pad 135 itself has a certain deformation capacity, so the guide rod 131 can slide up and down in the guide column 132 and can rotate slightly. When the chassis 61 moves along an uneven grain surface, the body 62 does not float straight up and down relative to the chassis 61, but can swing slightly within a certain range, so that the body 62 can float smoothly without getting stuck.

[0057] In this embodiment, only two groups of rollers 63 are provided. On the one hand, this is because the direction of the trolley is controlled by the bottom plate 4 and the trolley does not need to turn independently. On the other hand, this structure can increase the contact area between the rollers 63 and the grain surface.

[0058] It is understandable that the crawler 65 in the crawler trolley 6 can increase the contact area with the grain surface, which is conducive to increasing the friction. In other embodiments, the crawler trolley 6 can also be replaced by a conventional roller trolley without crawlers.

[0059] In other embodiments, the scraper may also be arranged on the body of the crawler vehicle 6 .

[0060] Embodiment 2 of a novel track-type warehouse closing device of the present invention:

[0061] The difference between the second embodiment and the first embodiment is that:

[0062] The third rail 4 is fixed on the bottom slider 3, and the lower end surface of the third rail 4 is always kept flush with the lower end of the first rail 2 or higher than the lower end surface of the first rail 2 to ensure that the lower end of the third rail 4 will not be buried by grain during storage. Figure 8 In the state shown, the chassis 7 is fixed on the vertical section 52 extending downwardly from the surface slider 5. The horizontal section 51 of the surface slider 5 is a dovetail-shaped claw that matches the dovetail groove 1 41.

[0063] Embodiment 3 of a novel track-type warehouse closing device of the present invention:

[0064] The difference between the third embodiment and the first embodiment is that:

[0065] A tension spring is arranged between the chassis 61 and the body 62. When the chassis 61 reaches the concave section of the grain surface, the body 62 floats relative to the chassis 61 and stretches the tension spring; when the chassis 61 reaches the convex section of the grain surface, the tension spring is reset and drives the body 62 to reset.

[0066] It should be emphasized that in order to ensure the force consistency of various parts of the vehicle body 62, multiple groups of tension springs are symmetrically arranged on the periphery of the floating connection structure 7 with the floating connection structure 7 as the center position.
