Description

Technical Field

[0002] In the grain storage sector, the levelness of grain piles has a profound impact on grain storage quality, ventilation, and subsequent management. However, currently, grain pile leveling primarily relies on manual labor. Manual leveling is not only extremely inefficient, requiring a significant amount of time to complete, especially in large-scale grain depots, but also physically demanding, leading to worker fatigue and impacting work quality. Furthermore, manual operation makes it difficult to ensure a highly uniform grain surface; uneven surfaces can result in uneven ventilation, localized dampness, and ultimately affect the overall storage quality of the grain.

The two ends are connected to the forward screw 502 and the reverse screw 503 respectively through universal joint connectors of model SG32-20-85 (with an inner diameter of 20.5mm in this embodiment). The forward screw 502, the reverse screw 503 and the connecting rod 505 are fixed by set screws (with a diameter of M3 in this embodiment).

[0072] The synchronous gear 506 is model 5M-30 D25, and the diameter of the center hole in the embodiment is 16mm. It is fixed to the right end of the reversing screw 503 by a set screw.

[0073] The positive lead screw nut 507 is model 3205-M and is installed on the positive lead screw 502. It can drive the positive lead screw nut 507 to move from the outer end to the inner end when the positive lead screw 502 rotates.

[0074] See Figure 13 The limiting bracket 508 is a plate-like structural component, consisting of two identical support arms at the upper end and a mounting base. The mounting base consists of a top wall and a vertical arm. Both the support arms and the mounting base are rectangular plate-like structural components. The width of the two support arms is equal to that of the top wall of the mounting base. The two identical support arms are vertically fixed to the top wall of the mounting base at both ends. The upper ends of the two identical support arms are respectively provided with identical through holes. The through holes are right-angled, with an elliptical end for passing through a flexible rope. The other end is open for inserting the flexible rope. The vertical arm of the mounting base is provided with fixing holes for installation. The width of the vertical arm is equal to the length of the top wall, and the vertical arm is vertically fixed to one side of the top wall.

[0075] Two identical limiting brackets 508 are installed at the top of the forward lead screw nut 507 and the reverse lead screw nut 504. The flexible wire rope 4 is inserted into the through hole on the two identical support arms, which can limit the flexible wire rope 4. In the embodiment, the diameter of the two identical circular holes is 5.

[0076] The lead screw support 509 is model BF25. Its bottom is welded and fixed to the square tube base 501. The lead screw support 509 has a built-in bearing structure in the middle, which is used in conjunction with the forward lead screw 502 and the reverse lead screw 503 to provide support for the forward lead screw 502 and the reverse lead screw 503.

[0077] The forward-rotating screw 502 and the reverse-rotating screw 503 are each mounted on a rectangular tube in a square tube base 501 using two identical screw supports 509 at both ends. The axes of symmetry of the forward-rotating screw 502 and the reverse-rotating screw 503 are parallel and coplanar with the axis of symmetry of the rectangular tube in a vertical plane. A forward screw nut 507 and a reverse screw nut 504 are respectively fitted on the right end of the forward-rotating screw 502 and the left end of the reverse-rotating screw 503. The forward-rotating screw 502 and the reverse-rotating screw 503 are connected by a universal joint connector of model SG32-20-85, a connecting rod 505, and an M3 set screw. The axes of symmetry of the forward-rotating screw 502, the reverse-rotating screw 503, and the connecting rod 505 are collinear, ensuring that the forward-rotating screw 502 and the reverse-rotating screw 503 are collinear. The synchronous gear 506 is installed on the right side of the reverse screw 503 and is connected to the second synchronous gear 304 of the driven mechanism 3 via the synchronous belt 306. This enables the forward screw 502 and the reverse screw 503 to rotate synchronously when the winding rod 2 rotates, causing the forward screw nut 507 and the reverse screw nut 504 to move to both sides. A limit bracket 508 for a flexible wire rope 4 is installed on the top of each of the forward screw nut 507 and the reverse screw nut 504. The upper end of the limit bracket 508 is provided with two through holes of the same diameter. In this embodiment, the diameter of the through holes is 5mm. The flexible wire rope 4 passes through these two through holes, so that the flexible wire rope 4 can move to both sides at a uniform speed when the winding rod 2 rotates, ensuring that the flexible wire rope 4 does not overlap during the winding process on the winding rod 2, thereby ensuring the stability of pulling the leveling rod 7.

[0078] See Figure 9 and Figure 12 The forward lead screw nut 507 and the reverse lead screw nut 504 are embedded in the nut rotation limiting groove 510, which can make the forward lead screw nut 507 and the reverse lead screw nut 504 not rotate with the forward lead screw 502 and the reverse lead screw 503, but only move horizontally.

[0079] See Figure 10 The balance bar 6 is composed of square tube structural components, including one long balance square tube and two short balance square tubes with the same structure.

[0080] Two identical short square tubes are welded and fixed at both ends of a balanced long square tube. The central axis of symmetry of the two identical short square tubes is perpendicular and coplanar with the central axis of symmetry of the balanced long square tube. The sidewalls of the two identical short square tubes are coplanar with the two end faces of the balanced long square tube. The bottom face of the two identical short square tubes is parallel to the central axis of symmetry of the balanced long square tube.

[0081] The balance bar 6 is installed inside the short square tube of the bottom support 101 in the power mechanism 1 and the second short square tube of the second bottom support 301 in the driven mechanism 3. Together with the flexible rope travel limiting mechanism 5, it integrates the power mechanism 1 and the driven mechanism 3, ensuring structural stability during equipment operation. In this embodiment, the balance rectangular tube and the two identical balance short square tubes are all made of 40×40mm square tubing. The length of the balance rectangular tube is 2m, and the height of the two identical balance short square tubes is 40mm.

[0082] See Figure 1 The grain leveling rod 7 is a square tube structure. The grain leveling rod 7 is connected to the coil rod 2 by two identical flexible ropes 4. The rotation of the coil rod 2 drives the grain leveling rod 7 to move on the grain surface to achieve the effect of leveling the grain. In this embodiment, the grain leveling rod 7 is a square tube with a length of 3m and a cross-section of 40×40mm.

[0083] See Figures 1 to 3 The power mechanism 1 is located at the left end and is connected to the left end of the cylindrical winch 2 via a disc coupling 103. The winch 2 is placed horizontally and runs through the entire length of the equipment. A flexible silk rope 4 is wound around the winch 2, and one end of the flexible silk rope 4 is welded and fixed to the winch 2. The driven mechanism 3 is located at the right end and is connected to the right end of the winch 2 via a disc coupling 303, serving to support the winch 2. The flexible silk rope travel limiting mechanism 5 is installed in the short square tubes and short square tube 2 on the power mechanism 1 and the driven mechanism 3 via a square tube base 501, located at one end of the equipment in the direction of the flexible silk rope 4 being pulled out; the balance bar 6 is installed in the short square tubes and short square tube 2 on the power mechanism 1 and the driven mechanism 3, located at the other end of the equipment in the direction of the flexible silk rope being pulled out.

[0084] See Figure 1 The balance bar 6 and the flexible rope travel limiting mechanism 5 are located at the rear and front ends of the entire device, respectively. The front end is the side in the direction in which the flexible rope 4 is pulled out, and the rear end is the side away from the flexible rope 4.

[0085] See Figure 9 The right end of the flexible rope travel limiting mechanism 5 is equipped with a synchronous gear 506, which is connected to the No. 2 synchronous gear 304 on the driven mechanism 3 via a synchronous belt 306.

[0086] The working principle of the intelligent grain stack leveling machine is as follows:

[0087] The power mechanism 1 drives the coil lever 2 to rotate, and the coil lever 2 winds the flexible silk rope 4, which pulls the leveling rod 7 to move on the grain surface. The limit bracket 508 in the flexible silk rope travel limiting mechanism 5 has a 5mm diameter circular hole. After the flexible silk rope 4 passes through this hole, its horizontal travel can be controlled, thereby controlling the smooth movement of the leveling rod 7. The balance bar 6 ensures that the power mechanism 1 and the driven mechanism 3 remain parallel during operation, allowing the leveling rod 7 to evenly level the grain surface.
