Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, specifically to a wheeled leveling machine. Background Technology

[0002] The uneven surface of grain after it is stored in warehouses has always been a troublesome problem. When grain is mechanically dumped into warehouses, it creates uneven piles of grain, requiring a lot of manpower to level the grain surface. Otherwise, it will have a significant impact on the daily maintenance of the grain.

[0003] Existing methods for leveling grain surfaces mostly involve manual leveling or mechanically driven leveling boards. These two methods are inefficient and labor-intensive, not only time-consuming and labor-intensive but also difficult to guarantee the quality of grain surface leveling. To address this, Chinese Patent Publication No. CN 219216867 U provides an automated and rapid grain surface leveling device, including a traction frame and a leveling beam. The traction frame is placed on the grain pile, and a winch and counterweight are installed on the traction frame. The winch is connected to the leveling beam through a winding steel wire, and the winch pulls the leveling beam to move and drag it across the grain pile to level the grain.

[0004] The aforementioned device uses a winch to pull a leveling beam across the grain pile to level the grain. This equipment is quite heavy and bulky, taking up a lot of space. The installation process using the leveling beam is rather complicated, and continuously pulling the heavy-load leveling beam requires a high-power motor, resulting in high long-term operating costs. Utility Model Content

[0005] This utility model provides a wheeled flattening machine to solve the shortcomings of existing devices, such as large space occupation, complicated installation steps and high operating costs.

[0006] The present invention adopts the following technical solution:

[0007] A wheeled grain leveling machine includes a drive unit and a grain leveling plate. The drive unit includes a base, a turntable, and a drive motor. The inner side of the top edge of the base is provided with several positioning holes. The turntable is rotatably mounted on the top surface of the base, and the edge of the turntable is provided with a handle. The handle has a through hole, which corresponds to the positioning hole as the turntable rotates. The drive unit also includes a movable positioning pin. When the turntable rotates to the target angle, the movable positioning pin passes through the through hole of the handle and the corresponding positioning hole in sequence. The drive motor is mounted on the turntable, and its output shaft is connected to a winch. A steel wire rope is wound on the winch, and the free end of the steel wire rope is connected to the grain leveling plate.

[0008] Furthermore, two winches are connected to the output shaft of the drive motor, each winch is wound with a steel wire rope, and the free end of each steel wire rope is connected to a flat plate.

[0009] Furthermore, the handle has a straight-line structure, and the axis of its through hole coincides with the axis of the positioning hole of the base.

[0010] Furthermore, the movable positioning pin is either a manual latch or a spring-loaded self-locking pin.

[0011] Furthermore, the flat grain plate is equipped with a connecting buckle, and the end of the wire rope is equipped with a hook that can be detachably connected to the connecting buckle.

[0012] 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:

[0013] 1. This utility model includes a drive device and a grain leveling plate. The drive device includes a base, a turntable, a drive motor, and a movable positioning pin. The drive motor is mounted on the base via the turntable, and its output shaft is connected to a winch and a wire rope. The drive motor controls the winch to tighten or release the wire rope, thereby pulling the grain leveling plate to achieve the purpose of leveling the grain. This grain leveling machine has a simple structure, small size, is easy to move, and has a low cost.

[0014] 2. This utility model first adjusts the angle and direction of the winch by rotating the turntable, and then fixes the turntable by passing the movable positioning pin through the through hole on the handle and the positioning hole on the base, which can realize multi-angle traction of the grain plate and improve the flexibility of equipment use.

[0015] 3. This utility model makes the drive device more stable through the interaction force of the two steel wire ropes on the double winch, and also improves the efficiency of leveling grain; at the same time, the detachable design of the steel wire ropes and the grain leveling plate facilitates operation and maintenance.

[0018] Figure 3 This is a schematic diagram of the structure of the flat grain board of this utility model. Detailed Implementation

[0019] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of this utility model; however, those skilled in the art can implement this utility model without these details. Well-known components, methods, and processes will not be described in detail below.

[0020] This embodiment provides a wheeled warehouse leveling machine, as shown in the following reference. Figure 1The system includes a drive unit 10 and two leveling plates 20. The drive unit 10 includes a base 101, a turntable 102, and a drive motor 103. The base 101 has several positioning holes 104. The turntable 102 is rotatably mounted on the base 101, and the edge of the turntable 102 has a handle 105. The handle 105 has a through hole 106, and the turntable 102 has a movable positioning pin 107. The handle 105 has a straight-line structure, and the axis of its through hole 106 coincides with the axis of the positioning hole 104 of the base 101.

[0021] Reference Figure 2 When the turntable 102 rotates to the target angle, the movable positioning pin 107 passes through the through hole 106 of the handle 105 and is embedded in the corresponding positioning hole 104 of the base 101 to fix the position of the turntable 102. The drive motor 103 is installed on the turntable 102, and its output shaft is connected to the winch 108. Two steel wire ropes 109 are wound on the winch 108. The free end of each steel wire rope 109 is connected to two flat grain plates 20 and moves in opposite directions.

[0022] The aforementioned drive motor 103 controls the winch 108 to tighten or release the wire rope 109, thereby pulling the grain leveling plate 20 to achieve the purpose of leveling the grain. This grain leveling machine not only occupies a small area and is easy to move, but also has a low cost. At the same time, rotating the turntable allows for adjustment of the winch angle and direction. Then, the turntable is fixed by a movable positioning pin passing through the through hole on the handle and the positioning hole on the base, which can realize multi-angle traction of the grain leveling plate and improve the flexibility of equipment use.

[0023] The aforementioned drive motor 103 is adjusted for forward and reverse rotation via a controller. Specifically, the drive motor 103 can rotate in both directions. When rotating forward, the wire rope 103 is tightened to pull the grain leveling plate 20 towards the drive device 10. When rotating in reverse, the wire rope 103 is released to continue operation. The free ends of the two wire ropes 109 are connected to the two grain leveling plates 20 respectively and move in opposite directions. Under the interaction force, the drive device 10 becomes more stable, improving the overall stability and also increasing the efficiency of leveling grain.

[0024] Continue to refer to Figure 2 The movable positioning pin 107 is preferably a manual pin or a spring self-locking pin. The movable positioning pin 107 is used to fix the turntable and prevent the turntable from moving.

[0025] Reference Figure 3 The flat grain plate 20 is equipped with a connecting buckle 201, and the end of the wire rope is equipped with a hook for detachable connection with the connecting buckle on the flat grain plate 20. The detachable design of the wire rope 109 and the flat grain plate 20 facilitates operation and maintenance.

[0026] A method for using a wheeled warehouse leveling machine includes the following steps:

[0027] S1. Place the drive unit 10 in a low-lying area of ​​the grain surface, adjust the turntable 102 to the target angle, and then insert the movable positioning pin 107 to fix it.

[0028] S2. Start the drive motor 103 to reverse, release the wire rope 109 on the winch 108 to the position of the leveling plate 20 and connect it to the leveling plate 20;

[0029] S3. The drive motor 103 rotates in the forward direction, and by tightening the two steel wire ropes 109, it pulls the two opposite grain leveling plates 20 to move towards the drive device 10, thereby leveling the grain surface.

[0030] 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.
