Description

Technical Field

[0001] This utility model relates to the field of rice processing feeding technology, and in particular to a rice feeding device that can control the amount of rice processed. Background Technology

[0002] Rice, also known as paddy rice, is a food made from paddy rice through processes such as cleaning, hulling, milling, and finishing. Rice is a staple food for people in most parts of my country.

[0003] A known authorized patent with application number CN202021569691.4 discloses a feeding device for rice processing. Its background art addresses the problem that "currently used impurity removal equipment has a low horizontal movement frequency, slow speed, and low impurity removal efficiency; most importantly, it cannot effectively clean dust from rice." To address this problem, the technical solution is as follows: "It includes a housing; a feeding cylinder is fixedly connected inside the housing; a motor support plate is fixedly connected to the left side of the housing; a first motor is fixedly connected to the motor support plate; a roller is provided inside the feeding cylinder; a cutting roller is fixedly connected to the outside of the roller; a through hole is opened at the bottom of the feeding cylinder; a support plate is fixedly connected inside the housing; a slide rail is fixedly connected inside the support plate; and a screening box is slidably connected in the slide rail."

[0004] However, the following problems were found in the implementation of the above technical solution: Although the provided technical solution achieves the effect of rice screening and impurity removal, it is not convenient to prevent blockage at the feed inlet. Due to the uneven particle size and shape of rice, as well as the influence of humidity, there may be large particles or lumps. When rice is poured into the feed inlet, a large amount of rice and lumps can easily accumulate and block the feed inlet, causing blockage. It is also inconvenient to feed rice in a quantitative manner, which can easily cause accumulation during the rice impurity removal process, affecting the speed and effect of impurity removal, thereby reducing the feeding effect and processing efficiency of rice. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a rice feeding device that can control the amount of rice processed, thereby solving the problems of inconvenience in preventing blockage at the feed inlet and inconvenience in quantitatively feeding and processing rice in the prior art.

[0006] To achieve the above objectives, this utility model provides a rice feeding device capable of controlling the amount of rice processed, comprising: a processing box, wherein a cleaning mechanism is provided inside the processing box; a feeding hopper fixedly installed on the top of the processing box; a bracket fixedly installed inside the feeding hopper; a slidable rod traversing and slidingly connected to the bracket; a rotating mechanism disposed in the feeding hopper and connected to the slidable rod, wherein the slidable rod moves up and down on the bracket via the rotating mechanism; a baffle plate disposed in the feeding hopper, wherein a slot is provided on one side of the feeding hopper and the baffle plate is slidably connected inside the slot; and a transmission mechanism disposed on the feeding hopper and connected to the baffle plate, and cooperating and linked with the rotating mechanism, wherein the baffle plate moves laterally within the slot via the transmission mechanism.

[0007] Furthermore, the rotating mechanism includes a crank rod rotatably connected inside the feed hopper, a connecting rod rotatably connected to the surface of the crank rod via a bearing and movably connected to the unblocking rod, and a power motor fixedly installed on one side of the feed hopper. The output end of the power motor movably passes through the feed hopper and is connected to the crank rod, and one end of the crank rod movably extends to the outside of the feed hopper.

[0008] Furthermore, the transmission mechanism includes a bevel gear one fixedly connected to one end of the crank rod, a rotating shaft rod rotatably connected to one side of the feed hopper via a base plate, a bevel gear two fixedly connected to the top of the rotating shaft rod and meshing with the bevel gear one, a rotating plate one fixedly connected to the bottom end of the rotating shaft rod, and a rotating plate two movably connected to the bottom of one end of the rotating plate one, with one end of the rotating plate two movably connected to the baffle plate.

[0009] Furthermore, the impurity removal mechanism includes a feeding guide plate fixedly installed inside the processing box, a screen plate located below the feeding guide plate, springs mounted on both sides of the inner wall of the processing box via base blocks and located at the four corners of the bottom of the screen plate, pads fixedly connected to the top of the springs and connected to the screen plate, and two vibration motors symmetrically fixedly installed on the top of the screen plate.

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

[0014] This invention uses a motor to drive a crank to rotate, which in turn drives a connecting rod to slide up and down on a support. The moving rod disperses and breaks up clumps of rice, preventing blockages. This prevents the feeding hopper from becoming clogged, ensuring smooth and continuous feeding and effectively improving the rice feeding efficiency.

[0015] This invention utilizes a crank to synchronously drive a first bevel gear, which in turn drives a second bevel gear. This, in turn, causes a rotating shaft to rotate a first rotating plate. The first rotating plate, through the second rotating plate, moves a baffle plate laterally within the slot, allowing for intermittent opening and closing of the feed hopper. This ensures that rice is fed into the processing box in an orderly and quantitative manner, achieving the effect of quantitative rice feeding. This avoids the problem of excessive feeding affecting the subsequent impurity removal speed, effectively improving the rice processing efficiency.

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of this utility model are now described with reference to the accompanying drawings. However, the scope of protection of this utility model is not limited to the following description.

[0023] Example 1

[0024] Reference Figure 1-4 As shown, a rice feeding device that can control the amount of rice processed includes: a processing box 1, with a cleaning mechanism inside the processing box 1; a feeding hopper 2 fixedly installed on the top of the processing box 1; a support 3 fixedly installed inside the feeding hopper 2; a slidable rod 4 slidably connected to the support 3; a rotating mechanism located in the feeding hopper 2 and connected to the slidable rod 4, the slidable rod 4 moving up and down on the support 3 via the rotating mechanism; a baffle plate 5 located inside the feeding hopper 2, with a slot on one side of the feeding hopper 2, the baffle plate 5 slidably connected inside the slot; and a transmission mechanism located on the feeding hopper 2 and connected to the baffle plate 5, and cooperating with the rotating mechanism, the baffle plate 5 moving laterally within the slot via the transmission mechanism.

[0025] The rotating mechanism includes a crank rod 6 rotatably connected inside the feed hopper 2, a connecting rod 7 rotatably connected to the surface of the crank rod 6 via a bearing and movably connected to the unblocking rod 4, and a power motor 8 fixedly installed on one side of the feed hopper 2. The output end of the power motor 8 movably passes through the feed hopper 2 and is connected to the crank rod 6, and one end of the crank rod 6 movably extends to the outside of the feed hopper 2.

[0026] The transmission mechanism includes a bevel gear 9 fixedly connected to one end of the crank rod 6, a rotating shaft 10 rotatably connected to one side of the feed hopper 2 via a base plate, a bevel gear 11 fixedly connected to the top of the rotating shaft 10 and meshing with the bevel gear 9, a rotating plate 12 fixedly connected to the bottom of the rotating shaft 10, and a rotating plate 13 movably connected to the bottom of one end of the rotating plate 12. One end of the rotating plate 13 is movably connected to the baffle plate 5.

[0027] The technical solution provided in this embodiment is as follows: During use, rice is temporarily stored inside the feeding hopper 2. During processing and feeding, the power motor 8 drives the crank 6 to rotate, and in conjunction with the connecting rod 7, drives the unblocking rod 4 to slide up and down on the support 3. This allows the up-and-down moving unblocking rod 4 to unblock and disperse aggregated and lumpy rice, preventing material blockage and thus achieving the function of feeding and preventing blockage in the feeding hopper 2. Simultaneously, during the rotation of the crank 6, it synchronously drives the bevel gear 9 to rotate, which in turn drives the meshing bevel gear 11 to rotate. This causes the rotating shaft 10 to drive the rotating plate 12 to rotate, and the rotating plate 12, through the rotating plate 2, drives the baffle plate 5 to move laterally within the slot, so as to intermittently open and close the feed hopper 2 to feed rice into the processing box 1 in an orderly and quantitative manner, thereby achieving the effect of quantitative rice feeding. Thus, the effects of anti-blocking and quantitative feeding are achieved, avoiding the situation where the feed hopper 2 is blocked, affecting the feeding, or the feeding amount is too large, affecting the subsequent impurity removal speed. This ensures the smoothness and continuity of feeding, and effectively improves the rice feeding effect and processing efficiency.

[0028] Preferably, the impurity removal mechanism includes a feeding guide plate 14 fixedly installed inside the processing box 1, a screen plate 17 located below the feeding guide plate 14, springs 15 installed on both sides of the inner wall of the processing box 1 and located at the four bottom corners of the screen plate 17 via base blocks, pads 16 fixedly connected to the top of the springs 15 and connected to the screen plate 17, and two vibration motors 18 symmetrically fixedly installed on the top of the screen plate 17, wherein the feeding guide plate 14 and the screen plate 17 are both inclined.

[0029] A rice collection shell 19 is slidably connected to the inner bottom wall of the processing box 1. A drawer slot for pulling out the rice collection shell 19 is opened on one side of the processing box 1, and a waste discharge port is opened on one side of the processing box 1.

[0030] Specifically, when rice enters the processing box 1, it rolls along the inclined surface of the feeding guide plate 14 and falls onto the screen plate 17. Simultaneously, the vibrating motor 18, in conjunction with the spring 15, causes the screen plate 17 to vibrate, thereby performing vibration screening and impurity removal on the rice. The rice falls through the screen plate 17 into the rice collection shell 19, filtering out impurities. These impurities then roll along the surface of the screen plate 17 and are discharged from the impurity discharge port, thus achieving the purpose of removing impurities from the rice and improving the convenience of subsequent rice processing.

[0031] Example 2

[0032] Based on Embodiment 1, in this embodiment: a flow channel is provided on the other side of the processing box 1, and an inclined baffle 24 is fixedly installed in the flow channel. A dust removal mechanism for cleaning dust from rice is provided on the side of the processing box 1.

[0033] The dust removal mechanism includes a dust collection shell 20 fixedly installed on one side of the processing box 1 and corresponding to the flow channel, a fan 21 fixedly installed on one side of the dust collection shell 20, a filter screen 22 fixedly installed inside the dust collection shell 20, and a dust collection shell 23 slidably connected to the bottom wall inside the dust collection shell 20.

[0034] The technical solution provided in this embodiment is as follows: When rice rolls down the feeding guide plate 14 to the screen plate 17, the fan 21 can suck the dust and chaff in the rice into the dust collection shell 20 and collect them into the dust collection shell 23, which facilitates further improvement of the impurity cleaning effect. At the same time, when the screen plate 17 removes impurities, the floating dust can be sucked up and collected again. By setting the filter screen 22, the dust and chaff can be prevented from entering the fan 21. By setting the inclined baffle 24, the falling rice can be prevented from accidentally entering the flow channel and causing waste. The dust collection shell 23 can be disassembled by pulling it out for dust treatment.

[0035] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
