[0032] Example 1

[0033] like Figures 1 to 8 As shown, a portable grain barrel provided by an embodiment of the utility model comprises a barrel body 1, a roller bracket 2 and a roller 3, wherein a mounting groove 4 is provided at the bottom of the barrel body 1, the roller bracket 2 is embedded in the mounting groove 4, an end of the roller bracket 2 away from the barrel body 1 is provided with an axis slot 20, the rotating shaft of the roller 3 is accommodated in the axis slot 20, and the size of the mounting groove 4 gradually decreases from the bottom of the barrel body 1 to the inside;

[0034] The mounting groove 4 and the roller bracket 2 are in interference fit, and the diameter of the rotating shaft is larger than the opening size of the shaft slot 20 .

[0035] The roller bracket 2 is a rectangular structure, made of a certain elastic material such as plastic, so that the opening of the shaft slot 20 can be deformed to a certain extent when subjected to force, so that the roller 3 can be smoothly installed and limited in the shaft slot 20. There is an arc transition between the mounting groove 4 and the side walls of the roller bracket 2. The mounting groove 4 and the roller bracket 2 are arranged in a structure that is narrow at the top and wide at the bottom. The roller bracket 2 and the mounting groove 4 are interference fit. When the roller bracket 2 is installed in the mounting groove 4, since the mounting groove 4 and the roller bracket 2 are fixed by extrusion, there is no need to use bolts to fix them.

[0036] The opening size of the shaft slot 20 is smaller than the rotating shaft of the roller 3. The roller 3 can be engaged in the shaft slot 20 by pressing the roller 3. When the barrel 1 is lifted, the shaft slot 20 can limit the roller 3. When the roller 3 needs to be replaced, the roller 3 can be pulled out to be separated from the shaft slot 20, which can realize the quick loading and unloading requirements.

[0037] The portable grain barrel provided by the utility model has a mounting groove 4 and a roller bracket 2 with a wide bottom and a narrow top. The roller bracket 2 and the mounting groove 4 are in an interference fit. When the roller bracket 2 is installed in the mounting groove 4, the roller bracket 2 is squeezed by the mounting groove 4 and fixed on the mounting groove 4. The firmness between the roller bracket 2 and the mounting groove 4 is strengthened by the weight of the barrel body 1 itself. The opening of the shaft slot 20 is smaller than the rotating shaft of the roller 3. After pressure is applied to the roller 3, the rotating shaft of the roller 3 enters the shaft slot 20 to achieve limiting. When using the portable grain barrel, the user can more conveniently perform the installation operation without the aid of any tools, thereby improving the flexibility of use, improving the efficiency of sales and stocking, and being highly convenient.

[0038] Furthermore, a plurality of ribs 40 are provided in the mounting groove 4 of the portable grain barrel, and the ribs 40 are in the same direction as the rotating shaft; the ribs 40 are provided in the mounting groove 4, and the ribs 40 are in the same direction as the rotating shaft, so as to improve the structural strength of the mounting groove 4 and avoid the risk of bending of the mounting groove 4 due to force when the barrel body 1 is tilted.

[0039] In this embodiment, the bottom end surface of the barrel body 1 is recessed inward to form the installation groove 4; or, the groove wall of the installation groove 4 extends outward away from the barrel body 1 and protrudes from the bottom end surface of the barrel body 1. The installation grooves 4 can be distributed in the four corner areas of the bottom of the barrel body 1, the bottom of the barrel body 1 can be recessed outward to form the installation groove 4, or a long straight plate can be arranged on the bottom end surface of the barrel body 1, and the long straight plate encloses a rectangular flange 5, and a mounting cavity for placing the roller bracket 2 is formed in the flange 5.

[0040] The barrel body 1 can be made of metal or plastic, such as stainless steel, aluminum alloy, polypropylene and other materials with high structural strength. When the barrel body 1 is made of stainless steel, the mounting groove 4 can be fixed to the bottom of the barrel body 1 by bolts or welding, or the mounting groove 4 and the barrel body 1 can be integrally formed by a die-casting process. When the barrel body 1 is made of plastic, the mounting groove 4 and the barrel body 1 are integrally formed by injection molding, and the structural strength of the mounting groove 4 is strengthened by the ribs 40 to reduce the risk of bending and deformation of the mounting groove 4 during use.

[0041] Furthermore, the outer periphery of the roller bracket 2 of the portable grain barrel is further provided with a plurality of convex ribs 21 distributed along the axial direction, and the thickness of the convex ribs 21 gradually decreases from the bottom of the roller bracket 2 toward the top of the roller bracket 2.

[0042] Specifically, a convex rib 21 is provided on the outer circumferential surface of the roller bracket 2, and the convex rib 21 is fixed to the mounting cavity by extrusion. In addition, the downward force of the barrel body 1 presses the roller bracket 2, thereby improving the connection strength between the roller bracket 2 and the mounting groove 4, ensuring that the roller bracket 2 is not easy to fall off the barrel body 1.

[0043] Furthermore, the top of the roller bracket 2 of the portable grain barrel is also provided with an avoidance groove 22, and the convex rib 21 forms a guide slope 23 with the top end surface of the roller bracket 2. After the roller 3 is installed on the roller bracket 2, the roller 3 will be slightly deformed when under pressure. In order to avoid the roller 3 rubbing against the roller bracket 2, an opening is opened at the top of the roller bracket 2 to avoid the roller 3, so that the roller 3 does not contact the roller bracket 2 during the rotation process, and the roller 3 is prevented from being stuck.

[0044] Furthermore, the barrel body 1 of the portable grain barrel and the mounting groove 4 are an integrally formed structure, and the roller bracket 2 and the roller 3 are made of plastic.

[0045] Further, an outwardly extending flange 5 is provided at the outer edge of the bottom end face of the barrel body 1 of the above-mentioned portable grain barrel, and the groove wall of the installation groove 4 is connected to the flange 5.
