Description

Technical Field

[0001] This utility model relates to a leveling device, specifically a track-type leveling device. Background Technology

[0002] Currently, most of the leveling work in my country's grain storage facilities is done manually. This is not only slow and wasteful of labor, but also labor-intensive. Moreover, it is difficult to guarantee the quality of leveling. In particular, for grain piles with large height differences, leveling machines are needed to achieve leveling.

[0003] Chinese patent application number 2019113011647 discloses a grain leveling machine, including two tracks installed on both sides of the inner wall of a grain silo and a base plate located inside the tracks. Track wheels are installed on both sides of the base plate, and a motor is installed on the base plate to drive the track wheels to rotate along the tracks. A leveling plate is provided at the lower end of the base plate. The leveling plate moves along the tracks, causing the base plate to move along the length of the grain silo. A threaded rod and a propulsion motor are also provided between the base plate and one end wall of the grain silo along its length to provide additional power for the movement of the base and prevent insufficient friction from hindering the movement of the leveling device.

[0004] The shortcomings of the existing technology are as follows: the threaded rod can only rotate along its own axis, but cannot be moved to the corners of the grain silo. The threaded rod placed in the middle of the grain silo divides the internal space of the silo along its length, which will obstruct the work of grain storage, storage, aisle board placement, and grain surface treatment, which is very inconvenient. At the same time, the processing and design of the threaded rod also presents challenges when the grain silo is long. Utility Model Content

[0005] The purpose of this utility model is to provide a track-type leveling device to solve the technical problems of existing track-type leveling devices affecting grain storage, warehousing, and grain surface treatment.

[0006] Therefore, the track-type leveling device of this utility model adopts the following technical solution:

[0007] A track-type leveling device includes two longitudinal rails installed on both sides of the inner wall of a grain silo and a transverse rail located on the longitudinal rails. The transverse rail can travel along the longitudinal rails. It also includes a trolley. A base plate is provided on the transverse rail so that it can travel along it. The trolley includes a chassis and a body that can float up and down relative to the chassis. The chassis is provided with rollers that can roll along the grain surface. A drive motor for driving the rollers to rotate is also provided on the chassis. The body and the base plate are connected by a ball joint to transmit power.

[0008] Furthermore, a floating connection structure is provided between the chassis and the vehicle body. The floating connection structure includes a guide rod and a guide column. The guide rod is fixed on one of the chassis and the vehicle body, and the guide column is fixed on the other. The guide rod is inserted into the guide column.

[0009] Furthermore, the floating connection structure is located in the middle of the chassis.

[0010] Furthermore, the end of the guide rod is provided with a protrusion, and the corresponding end of the guide post is provided with an anti-detachment section to prevent the protrusion from detaching from the guide post. An elastic pad is provided on the inner circumference of the anti-detachment section, and the inner diameter of the elastic pad matches the size of the guide rod.

[0011] Furthermore, the anti-detachment section has grooves on three sides for the corresponding parts of the elastic pad to be inserted.

[0012] Furthermore, the vehicle is a tracked vehicle with two sets of rollers at the lower end of the chassis. The drive motor is used to drive one set of rollers to rotate, and a track is provided between the two sets of rollers to transmit power.

[0013] Furthermore, longitudinal guide wheels are provided at both ends of the horizontal rail, and a longitudinal drive motor for driving the longitudinal guide wheels to rotate is installed on the horizontal rail; grooves are provided on both sides of the horizontal rail, and transverse guide wheels are installed on both sides of the base plate, the transverse guide wheels are embedded in the grooves, and a transverse drive motor for driving the transverse guide wheels to rotate on the horizontal rail is also installed on the base plate.

[0014] Furthermore, a scraper for leveling the grain surface is installed on the base plate or the vehicle body.

[0015] Furthermore, a tension spring is provided between the chassis and the vehicle body.

[0016] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, the trolley is only used to push the base plate, providing auxiliary power for its movement. The leveling position is adjusted by moving the base plate laterally and longitudinally along the track. This ensures that there are no blind spots in the leveling work within the grain warehouse and provides sufficient power for the movement of the base plate, preventing the scraper from failing to move due to insufficient power.

[0018] 2. The trolley moves along the track. When leveling is not required, the base plate can be pushed to a corner of the grain silo, and the trolley will move accordingly, occupying little space. The ball joint between the trolley and the base plate can also be removed. Therefore, this invention also has the effect of not obstructing grain entry and exit, the placement of walkway panels, and grain surface treatment.

[0019] 3. When the trolley moves along the grain surface, the body floats relative to the chassis to ensure that the power of the body movement can be transmitted to the bottom plate through the ball joint.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] Embodiment 1 of a track-type leveling device of this utility model:

[0031] The specific structure of the track-type leveling device of this utility model is as follows: Figures 1 to 5 As shown, the silo includes two longitudinal rails 1 installed on both sides of the inner wall of the grain silo 3 and a transverse rail 2 located on the longitudinal rails 1, as well as a tracked trolley 6 that travels along the grain surface. The transverse rail 2 has longitudinal track wheels at both ends, and a longitudinal drive motor is installed on the transverse rail 2 to drive the longitudinal track wheels to rotate on the longitudinal rail 1. A base plate 4 is slidably mounted on the transverse rail 2, along which a transverse track wheel 41 is installed on both sides of the base plate 4, and a transverse drive motor is also installed on the base plate 4 to drive the transverse track wheels 41 to rotate on the track 1.

[0032] In this application, grooves 21 are provided on both sides of the horizontal rail 2, and horizontal movement track wheels 41 are installed on both sides of the base plate 4, with the horizontal movement track wheels 41 embedded in the grooves 21. In this configuration, the base plate 4 is suspended below the horizontal rail 2, and the scraper is fixed to the lower end of the base plate 4.

[0033] The tracked trolley 6 includes a chassis 61, a body 62, rollers 63, a drive motor 64, and tracks 65. The rollers 63 are rotatably mounted below the chassis 61, while the body 62 floats above it. The tracks 65 wrap between the front and rear sets of rollers 63 to increase the contact area between the tracked trolley 6 and the grain surface. The drive motor 64 drives the rollers 63 to rotate. The body 62 is fixed to the base plate 4, and a scraper is connected to the lower end of the base plate 4. The drive motor 64 transmits power to the rollers 63 via a gear structure (not shown). The front end of the body 62 is connected to the base plate 4 via a ball joint 8. The spherical shell of the ball joint 8 is fixed to the front end of the body 62, and the ball joint rod is hinged to the base plate 4. Therefore, the tracked trolley 6 can both push and pull the base plate 4, and power can be transmitted smoothly even when the angle between the body 62 and the base plate 4 changes.

[0034] A floating connection structure 7 is provided between the chassis 61 and the body 62. The floating connection structure 7 includes a guide rod 71 fixed above the chassis 61 and a guide post 72 fixed below the body 62. The guide rod 71 is inserted into the guide post 72 along the axis. The upper end of the guide rod 71 has a protruding section 73 protruding outward. The guide post 72 includes an anti-detachment section 74. When the body 62 is raised relative to the chassis 61, the anti-detachment section 74 can cooperate with the protruding section 73 to prevent the body 62 from detaching from the chassis 61. An elastic pad 75 is fitted on the inner circumferential surface of the anti-detachment section 74. The anti-detachment section 74 has grooves 76 on three sides for corresponding parts of the elastic pad 75 to be embedded to increase the bonding strength between the elastic pad 75 and the anti-detachment section 74.

[0035] In this embodiment, both the guide rod 71 and the guide post 72 are fixed to the corresponding base by bolts and flanges.

[0036] The inner diameter of the elastic pad 75 matches the size of the guide rod 71, but the elastic pad 75 itself has a certain deformation capacity. Therefore, the guide rod 71 can slide up and down within the guide post 72 and also rotate slightly. When the chassis 61 travels along an uneven grain surface, the floating of the vehicle body 62 relative to the chassis 61 is not straight up and down, but can swing slightly within a certain range, allowing the vehicle body 62 to float smoothly without getting stuck.

[0037] In this embodiment, only two sets of rollers 63 are provided. This is because the direction of the trolley is controlled by the base plate 4, and the trolley does not need to turn separately. On the other hand, this structure can increase the contact area between the rollers 63 and the grain surface.

[0038] Understandably, the tracks 65 in the tracked trolley 6 increase the contact area with the grain surface, which is beneficial for increasing friction. In other embodiments, the tracked trolley 6 can also be replaced by a conventional roller trolley without tracks.

[0039] In other embodiments, the scraper may also be mounted on the body of the tracked trolley 6.

[0040] Embodiment 2 of the track-type flattening device of this utility model:

[0041] The difference between Example 2 and Example 1 is that,

[0042] A tension spring is provided between the chassis 61 and the body 62. When the chassis 61 moves to 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 moves to the convex section of the grain surface, the tension spring returns to its original position and drives the body 62 to return to its original position.

[0043] It should be emphasized that, in order to ensure the consistency of force on all parts of the vehicle body 62, multiple sets of tension springs are symmetrically arranged around the floating connection structure 7 as the center.
