Description

Technical Field

[0001] This utility model relates to the field of grain storage leveling technology, specifically a grain surface leveling device inside a storage facility. Background Technology

[0002] In grain storage, leveling the grain silo is a necessary process. As grain is put into and taken out of the silo, after the grain intake is completed, high grain piles and deep grain pits will appear on the grain surface. In order to improve the space utilization of the grain silo, it is necessary to level the grain surface.

[0003] Currently, leveling operations inside grain warehouses are generally carried out manually or using leveling equipment. Manual handling is time-consuming, labor-intensive, inefficient, increases the workload and labor costs for workers, and is not conducive to energy conservation and emission reduction. While leveling equipment is used, its application is limited; it can only level relatively low grain piles and shallow grain pits. It cannot level high grain piles that have just been unloaded or deep depressions formed on the grain surface after leaving the warehouse, ultimately requiring manual handling for filling and leveling. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of time-consuming and labor-intensive manual handling during leveling operations in grain warehouses, and the inability of leveling equipment to level high grain piles and deep depressions formed on the grain surface after grain is removed from the warehouse.

[0005] The present invention adopts the following technical solution: A grain surface leveling device for warehouses includes a grain transport frame, on which a grain cart is provided that can move back and forth along the length of the grain transport frame, and the legs of the grain transport frame are provided with a first support plate for placing the grain transport frame on the grain surface inside the warehouse.

[0006] Furthermore, the top surface of the grain transport rack is provided with a running track for the movement of the grain vehicle, and the bottom surface of the grain vehicle is provided with rollers that cooperate with the running track.

[0007] Furthermore, one end of the grain transport rack is provided with several telescopic frames along its length, and the traveling track extends to the top surface of the telescopic frames.

[0008] Furthermore, the travel track is a track with a U-shaped groove in cross-section.

[0009] Furthermore, the two ends of the walking track are provided with stops.

[0010] Furthermore, the support leg is a plurality of detachable first support columns, the upper end of the first support column being detachably connected to the bottom surface of the grain transport rack, and the lower end being detachably connected to the first support plate.

[0011] Furthermore, the bottom surface of the telescopic frame is detachably provided with a plurality of second support columns, and the lower end of the second support frame is detachably connected to a second support plate.

[0012] Furthermore, the first support plate and the second support plate are arc-shaped plates.

[0013] Furthermore, the grain truck has unloading ports on its left and right side panels, and the unloading ports are hinged with flip-up flaps.

[0014] Furthermore, the lifting plate is provided with a pin, and the side plate of the grain cart is provided with a pin hole seat that matches the pin.

[0015] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: 1. Compared with existing leveling equipment, this utility model can level tall grain piles and deep grain pits formed after grain discharge, without consuming electricity; it only requires workers to pull the cart back and forth. Compared with manual handling, workers only need to push the grain cart to complete the transport, greatly reducing the workload and handling time. This utility model has the advantages of simple operation, low cost, flexible mobility, fast and efficient operation, and good adaptability.

[0016] 2. The grain transport frame of this utility model is equipped with several telescopic frames, which can freely adjust the transport length of the grain transport frame and is suitable for the distance between different grain piles and grain surface depressions.

[0017] 3. The grain cart, grain transport rack, first support column, second support column, first support plate and second support plate of this utility model are detachably connected, so that the staff can disassemble and transport this utility model to the grain surface in the warehouse for assembly and use. It is easy to transport and store.

[0018] 4. This utility model increases the contact area between the device and the grain surface in the warehouse by using the first support plate and the second support plate, so that the device will not sink into the grain surface due to excessive pressure from the grain truck when transporting grain; at the same time, the first support plate and the second support plate are both arc-shaped plates, which makes it easy to push the device to the working position on the grain surface in the warehouse.

[0023] Figure 5 This is a schematic diagram illustrating the application scenario of this utility model.

[0024] The components in the diagram are labeled as follows: grain transport frame 10, traveling track 11, stop block 111, grain car 20, lifting plate 21, pin 211, pin hole seat 212, first support column 30, first support plate 40, telescopic frame 50, second support column 60, and second support plate 70. Detailed Implementation

[0025] The specific implementation of the present invention will now be described with reference to the accompanying drawings.

[0026] Reference Figure 1 and Figure 2 A grain surface leveling device for a grain storage facility includes a grain transport frame 10 made of aluminum alloy. The support legs of the grain transport frame 10 are several detachable first support columns 30. Both ends of each first support column 30 have grooves. The upper groove engages with a corresponding protrusion on the bottom surface of the grain transport frame 10, and the lower groove engages with a corresponding protrusion on a first support plate 40. The first support plate 40 is an arc-shaped plate to prevent excessive pressure from the grain cart 20 moving along the track 11 on the grain transport frame 10, which could cause the entire device to sink into the grain surface. Simultaneously, the arc-shaped structure reduces the friction between the bottom surface of the arc-shaped plate and the grain surface inside the storage facility during dragging, allowing storage facility workers to move the entire device more easily.

[0027] The grain transport frame 10 has several telescopic frame sections 50 at one end along its length. Each telescopic frame section 50 has several detachable second support columns 60 connected to its bottom end at the telescopic end. Both ends of the second support column 60 have grooves; the upper groove engages with the corresponding protrusion at the telescopic end of the telescopic frame 50, and the lower groove engages with the corresponding protrusion of the second support plate 70. The second support plate 70 is an arc-shaped plate to prevent excessive pressure from causing the telescopic frame 50 to sink into the grain surface when the grain cart 20 moves along the track 11 on the grain transport frame 10.

[0028] Reference Figure 4 The top surface of the grain transport rack 10 is provided with two traveling tracks 11 for the movement of the grain cart 20. The traveling tracks 11 are designed as U-shaped grooves in cross-section. The traveling tracks 11 extend from the grain transport rack 10 to the top surface of the telescopic frame 50. Stops 111 are welded to both ends of the traveling tracks 11 to prevent the grain cart 20 from leaving the track at the end of the traveling track 11 when moving.

[0029] Reference Figure 1and Figure 3 The grain cart 20 is placed on the top surface of the grain transport rack 10, and the bottom of the grain cart 20 is equipped with rollers that are compatible with the travel track 11, so that the grain cart 20 can move back and forth along the length of the grain transport rack 10. A handle is welded in the middle of the front and rear side plates of the grain cart 20 in the direction of movement, which is used to pull the grain cart 20 back and forth on the travel track 11.

[0030] The grain truck 20 has unloading ports (not shown in the figure) on its left and right side plates along its direction of movement. A hinged, upward-opening flap 21 is attached to each unloading port for unloading. A handle is welded to the bottom of the flap 21 for flipping it upwards during unloading. Two rotatable pins 211 are installed on both sides of the bottom of the flap 21. Pin holes 212, compatible with the pins 211, are installed on the side plates to prevent the flap 21 from opening under force during loading and movement of the grain truck 20, thus preventing grain from leaking out of the unloading ports.

[0031] The length and width of the opening at the top of the grain car 20 are slightly larger than the bottom surface. The grain car 20 as a whole is an inverted ladder with an opening at the top, which increases the grain loading capacity of the grain car 20.

[0032] Specifically, refer to Figures 1 to 5 This embodiment describes a grain surface leveling device for a grain warehouse. During operation, workers first disassemble the device into parts, transport them to the grain surface in the warehouse, and then assemble them one by one into a complete device. Then, referring to... Figure 5 The grain transport rack 10 is placed on one side of the grain pile on the grain surface inside the warehouse, with the telescopic frame 50 of the grain transport rack 10 facing and extending to the recessed area on the grain surface inside the warehouse.

[0033] The grain cart 20 is placed on the travel track 11 on the top surface of the grain transport rack 10. The pin 211 on the lifting plate 21 is inserted into the pin hole seat 212 on the side plate of the grain cart 20 to ensure that the lifting plate 21 will not open under force when loading grain and pulling the grain cart 20. The staff loads the grain into the grain cart 20. After the grain in the grain cart 20 is loaded into the predetermined position, the grain cart 20 is pulled to the side of the recess on the grain surface in the silo. The pin 211 is opened and the lifting plate 21 is flipped upward. The grain in the grain cart 20 will fall into the recess on the grain surface from the unloading port.

[0034] After the grain in the grain cart 20 is unloaded, it is pulled back to the grain pile to continue the next operation until the entire grain pile is moved into the recessed area of ​​the grain surface inside the silo. If there are multiple grain piles in the silo, after moving one grain pile, the second support column and the second support plate can be disassembled, the telescopic frame 50 can be retracted, and the entire device can be manually pushed to the next grain pile to continue the operation. Because the first support plate 40 is an arc-shaped plate, the staff can easily push the entire device, making it flexible, time-saving, and labor-saving.

[0035] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
