Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice milling machine technology, and more specifically, to a feeding hopper for a rice milling machine. Background Technology
[0002] A rice milling machine is a mechanical device that removes the husk from rice, processing brown rice into white rice while simultaneously separating rice, bran, and broken rice. The feed hopper is the device in a rice milling machine used to guide the rice into the mill. Currently, the feed hopper in commercially available rice milling machines mainly includes a feed hopper body, an upper gate, a lower gate, a first drive assembly, and a second drive assembly. The upper and lower gates are inserted into the feed hopper body at intervals and can both move left and right relative to the feed hopper body. Both the first and second drive assemblies are connected to the feed hopper body. The first drive assembly is used to drive the upper gate to move left and right relative to the main body of the feeding hopper, and the second drive assembly is used to drive the lower gate to move left and right relative to the main body of the feeding hopper. In the above feeding hopper structure, since the first drive assembly and the second drive assembly are used to independently drive the upper gate and the lower gate to move relative to the main body of the feeding hopper, and the movement stroke of the upper gate is not limited by the lower gate, when the opening of the upper gate relative to the main body of the feeding hopper is large and the opening of the lower gate relative to the main body of the feeding hopper is small, rice will accumulate in the main body of the feeding hopper and cause blockage of the main body of the feeding hopper. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a feeding hopper for a rice milling machine, which can prevent rice from accumulating in the main body of the feeding hopper and causing blockage of the main body of the feeding hopper when rice is being fed.
[0004] This utility model provides a feeding hopper for a rice milling machine, including a feeding hopper body, an upper gate, a lower gate, a first drive assembly, and a second drive assembly. The upper and lower gates are inserted into the feeding hopper body at an interval and can move left and right relative to the feeding hopper body. The first drive assembly and the second drive assembly are both connected to the feeding hopper body. The first drive assembly drives the upper gate to move left and right relative to the feeding hopper body, and the second drive assembly drives the lower gate to move left and right relative to the feeding hopper body. A first limiting part is provided on the outer end of the upper gate, and a second limiting part is provided on the lower gate. The first limiting part abuts against the second limiting part to limit the movement stroke of the upper gate.
[0005] By adopting the above structure, under the action of the first limiting part and the second limiting part, during the process of the upper gate moving back and forth relative to the main body of the feeding hopper driven by the first driving component, the first limiting part can abut against the second limiting part to limit the movement stroke of the upper gate, so that the movement stroke of the upper gate is limited by the lower gate, or in other words, the opening of the upper gate relative to the main body of the feeding hopper is always less than or equal to the opening of the lower gate relative to the main body of the feeding hopper, thereby preventing rice from accumulating in the main body of the feeding hopper and causing blockage of the main body of the feeding hopper when rice is being fed.
[0006] In one possible implementation, the first drive assembly includes two cylinders fixed symmetrically to the feed hopper body, with the piston rods of both cylinders fixed to the first limiting part.
[0007] In one possible implementation, the second drive assembly includes a servo motor, a lead screw, and a nut; the servo motor is fixed on the main body of the feed hopper, one end of the lead screw is coaxially fixed to the output shaft of the servo motor via a coupling, the nut is fixed on the second limiting part, and the lead screw passes through the nut and is threadedly connected to the nut.
[0008] In one possible implementation, an electronic ruler is fixed to the main body of the feed hopper, and the probe of the electronic ruler is fixed to the second limiting part.
[0009] In one possible implementation, a buffer block is fixed on the second limiting part, and the buffer block is used to abut against the first limiting part.
[0010] In one possible implementation, the first limiting part is formed by bending the outer end of the upper gate plate, and the second limiting part is formed by bending the outer end of the lower gate plate. Attached Figure Description

Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.
[0013] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. 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. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.
[0014] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0015] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0016] See Figure 1 As shown in the figure, this application discloses a feeding hopper for a rice milling machine, including a feeding hopper body 1, an upper gate plate 2, a lower gate plate 3, a first drive assembly, and a second drive assembly. The upper gate plate 2 and the lower gate plate 3 are inserted into the feeding hopper body 1 at an interval between the upper and lower parts and can move left and right relative to the feeding hopper body 1. The first drive assembly and the second drive assembly are both connected to the feeding hopper body 1. The first drive assembly is used to drive the upper gate plate 2 to move left and right relative to the feeding hopper body 1, and the second drive assembly is used to drive the lower gate plate 3 to move left and right relative to the feeding hopper body 1. A first limiting part 21 is provided on the outer end of the upper gate plate 2, and a second limiting part 31 is provided on the lower gate plate 3. The first limiting part 21 is used to abut against the second limiting part 31 to limit the movement stroke of the upper gate plate 2.
[0017] The first drive assembly includes two cylinders 4 fixed symmetrically to the feed hopper body 1. The piston rods of both cylinders 4 are fixed to the first limiting part 21. By adopting this first drive assembly, when the piston rods of the cylinders extend or retract, they can drive the upper gate to move left or right relative to the feed hopper body, thereby adjusting the opening of the upper gate relative to the feed hopper body. Since there are two cylinders, which are symmetrically arranged, the upper gate can be smoothly driven to move left or right relative to the feed hopper body.
[0018] The second drive assembly includes a servo motor 51, a lead screw 52, and a nut 53. The servo motor 51 is fixed on the feed hopper body 1. One end of the lead screw 52 is coaxially fixed to the output shaft of the servo motor 51 via a coupling 54. The nut 53 is fixed on the second limiting part 31. The lead screw 52 passes through the nut 53 and is threadedly connected to the nut 53. By adopting this second drive assembly, when the servo motor drives the lead screw to rotate, the lower gate can be driven to move left and right relative to the feed hopper body under the cooperation of the lead screw and the nut. This allows adjustment of the opening degree of the lower gate relative to the feed hopper body. When the servo motor stops driving the lead screw to rotate, the position of the lower gate relative to the feed hopper body can be locked under the cooperation of the lead screw and the nut.
[0019] An electronic ruler 6 is fixed on the main body 1 of the feeding hopper. The probe of the electronic ruler 6 is fixed to the second limiting part 31. With the setting of the electronic ruler, when the lower gate moves relative to the main body of the feeding hopper, the electronic ruler can detect the displacement and transmit the displacement to the controller. This allows the controller to obtain the displacement of the lower gate in real time. The controller can also dynamically control the first drive component and the second drive component based on the displacement to adjust the feed flow of the rice milling machine and control the output of the entire production line.
[0020] A buffer block 7 is fixed on the second limiting part 31. The buffer block 7 is used to abut against the first limiting part 21. By setting the buffer block, the buffer block can buffer the abutment process of the first limiting part and the second limiting part, thereby avoiding the impact damage to the first limiting part and the second limiting part.
[0021] The first limiting part 21 is formed by bending the outer end of the upper gate plate 2, and the second limiting part 31 is formed by bending the outer end of the lower gate plate 3. By adopting this structure, it has the advantages of easy formation of the first limiting part and good integrity with the upper gate plate, and also has the advantage of high connection strength between the first limiting part and the upper gate plate. Similarly, it has the advantages of easy formation of the second limiting part and good integrity with the lower gate plate, and also has the advantage of high connection strength between the second limiting part and the lower gate plate.
[0022] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
