Description

Technical Field

[0001] This utility model relates to the field of rice conveying box technology, specifically a rice conveying box for a rice milling machine. Background Technology

[0002] A rice milling machine is a mechanical device used to process paddy rice into polished rice, while a rice conveyor is a component used in conjunction with the rice milling machine to temporarily store or transport the rice produced by the machine. The rice milling machine removes the husk and bran from the paddy rice, yielding polished rice. The rice conveyor receives this polished rice and transports it to subsequent packaging or other processing stages.

[0003] However, existing methods of conveying rice either use free fall for direct vertical transport or use spiral blades for horizontal or oblique transport. Both methods share the same drawback: the lack of a mechanism to stop the transport. When it is necessary to stop the transport, the upstream processing equipment can only be indirectly controlled to achieve this. In addition, free fall and spiral blades cause excessive compression and friction of the rice grains, which can easily lead to grain breakage and damage to the quality of the rice. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is: to provide a rice conveying box for a rice milling machine, including a box body, with limit baffles connected to the two sides of the lower part of the box body, a support plate connected below the two limit baffles, and a discharge port provided at the bottom of the box body between the two limit baffles. A movable conveying pipe is slidably arranged between the box body and the support plate; the movable conveying pipe includes a blocking slide plate and a through pipe connected to each other.

[0005] Preferably, the height of the movable conveying pipe is adapted to the distance between the bottom of the box and the support plate.

[0006] Preferably, the blocking slide includes a blocking part, and two limiting guide parts extend outward from one side of the blocking part. The space between the two limiting guide parts cooperates with the limiting baffle. The left side of the blocking part is provided with a through-hole that cooperates with the discharge port, and a through pipe is connected below the through-hole.

[0007] Preferably, a guide groove matching the limit baffle is provided on the limit guide near the limit guide portion.

[0008] Preferably, the conduit includes a first curved section, an inclined section, and a second curved section connected in sequence; the end of the inclined section connected to the first curved section is higher than the end connected to the second curved section.

[0009] Preferably, the top of the box has a feed inlet, and the box has a tapered structure that is wider at the top and narrower at the bottom.

[0010] Preferably, the feed inlet is provided with a guide edge; the guide edge is located above the discharge outlet, and is higher in the middle and lower on both sides.

[0011] Preferably, an agitator is connected below the guide.

[0012] Preferably, the agitation assembly includes a motor and an agitation rod driven by the motor; the motor is connected to the guide edge via a fixed frame, and the agitation rod is provided with several agitation branches.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model features a simple structure and ingenious design. By setting a limiting baffle and a support plate at the bottom of the box, a limiting space is formed, allowing the movable conveying pipe to slide within this space. By changing the positional relationship between the blocking slide plate and the through pipe of the movable conveying pipe and the discharge port of the box, the opening and closing of the discharge port can be achieved, controlling the conveying of rice grains and providing a stop function. Furthermore, this utility model avoids free fall and spiral blade conveying methods, reducing excessive compression and friction of rice grains and minimizing rice grain breakage.

Detailed Implementation

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 This embodiment provides a rice conveying box for a rice milling machine, including a box body 1. Limiting baffles 2 are connected to both sides of the lower part of the box body 1. A support plate 3 is connected below the two limiting baffles 2. A discharge port 4 is located at the bottom of the box body 1 between the two limiting baffles 2. A movable conveying pipe 5 is slidably arranged between the box body 1 and the support plate 3. The movable conveying pipe 5 includes a blocking slide plate 6 and a through pipe 7 connected to each other. In use, the movable conveying pipe 5 can slide within the limiting space, changing the positional relationship between the blocking slide plate 6, the through pipe 7, and the discharge port 4 of the box body 1, thereby opening and closing the discharge port 4 and controlling the conveying of rice grains. Specifically, by controlling the blocking slide plate 6, the movable conveying pipe 5 can slide left and right between the two limiting baffles 2. When the blocking slide plate 6 abuts against the discharge port 4, the discharge port 4 is closed, stopping the discharge; when the through pipe 7 is connected to the discharge port 4, the discharge port 4 is open, continuing the discharge.

[0026] As for the control of the main slide plate 6, it can be manually operated or connected to any existing linearly driven mechanism to achieve automatic control. The specific control method is not the inventive point of this application, and therefore will not be described in detail.

[0027] In one embodiment, the height of the movable delivery pipe 5 is adapted to the distance between the bottom of the box 1 and the support plate 3.

[0028] In one embodiment, please refer to Figure 3 The blocking slide plate 6 includes a blocking part 8. Two limiting guide parts 9 extend outward from one side of the blocking part 8. The space between the two limiting guide parts 9 cooperates with the limiting baffle 2. A through port 10 that cooperates with the discharge port 4 is provided on the left side of the blocking part 8. A through pipe 7 is connected below the through port 10.

[0029] Further, please refer to Figure 1A guide groove 11 is provided on the limit baffle 2 near the limit guide part 9. The limit guide part 9 can slide back and forth along the guide groove 11 to further ensure the stability of the movement of the movable conveying pipe 5.

[0030] To further enhance the stability of the moving conveyor pipe, the bottom surface of pipe 7 is a plane (see...). Figure 1 , Figure 4 The inner cross-section of the through pipe 7 can be circular (see...). Figure 4 Square, trapezoidal (see also) Figure 1 It can be any shape, such as a circle. Of course, when it is round, the inner wall of the tube 7 is smoother, which will cause less damage to the rice grains.

[0031] In one embodiment, please refer to Figure 4 Preferably, the inner cross-section of the through pipe 7 is circular. To prevent rice grains from accumulating inside the through pipe 7 during transport, the inner wall of the through pipe 7 is curved. Specifically, the through pipe 7 includes a first curved section 12, an inclined section 13, and a second curved section 14 connected in sequence. The first curved section 12 connects to the outlet 10 and is used to receive rice grains falling from the discharge port 4 of the box 1, preventing rice grains from being squeezed into corners and difficult to flow out. The end of the inclined section 13 connected to the first curved section 12 is higher than the end connected to the second curved section 14, providing an inclined angle, which allows the rice grains to slide along the inclined pipe wall while avoiding the impact of free fall. The second curved section 14 bends downwards, guiding the rice grains to the next stage of equipment. Simultaneously, the downward-curving pipe opening also reduces the possibility of rice grains contaminating the environment.

[0032] Please see Figure 2 In one embodiment, the top of the box 1 is provided with a feeding port 15, and the box 1 has a conical structure that is wider at the top and narrower at the bottom. This facilitates the control of rice grain feeding and discharging.

[0033] Furthermore, the feed inlet 15 is provided with a guide edge 16, which is located above the discharge outlet 4 and is higher in the middle and lower on both sides.

[0034] Please see Figure 5 To prevent excessive accumulation of rice grains in the rice feeding box, which could create adhesion and make the grains difficult to disperse, resulting in difficulty in discharging the rice, an agitator is connected below the guide rail 16 to disperse the rice grains. Specifically, the agitator includes a motor 17 and an agitator rod 18 driven by the motor 17. The motor 17 is connected to the guide rail 16 via a mounting bracket, and the agitator rod 18 has several agitation branches 19.

[0035] This utility model has a simple structure and ingenious design. By setting a limiting baffle 2 and a support plate 3 below the box body 1, a limiting space is formed, allowing the movable conveying pipe 5 to slide in the limiting space. By changing the positional relationship between the blocking slide plate 6 and the through pipe 7 of the movable conveying pipe 5 and the discharge port 4 of the box body 1, the opening and closing of the discharge port 4 can be realized, thereby controlling the conveying of rice grains.

[0036] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
