Description

Technical Field

[0001] This utility model belongs to the field of rice processing technology, specifically an angle buffer. Background Technology

[0002] In the rice processing industry, rice quality is a key factor influencing its market value. Whole, plump rice grains significantly increase the selling price and market competitiveness of rice, while excessive broken rice not only reduces the milling yield but also deteriorates the appearance and taste of the rice, leading to a substantial price reduction. Therefore, reducing the rice breakage rate remains a crucial issue that urgently needs to be addressed in rice processing.

[0003] Meanwhile, the patent specification with publication number CN209109229U discloses a feed inlet buffer, "including a feed cylinder; a feed inlet is provided at the top of the feed cylinder; a first buffer mechanism, a second buffer mechanism, and a third buffer mechanism are provided sequentially from top to bottom on the upper part of the feed cylinder; a dispersion umbrella is provided below the third buffer mechanism; the upper surface of the dispersion umbrella is connected to the lower surface of the buffer plate of the third buffer mechanism through support rods; a collection hopper is provided at the bottom of the dispersion umbrella; the inclination angle of one side wall of the collection hopper is greater than the inclination angle of the other side wall; an inclined guide plate is provided below the collection hopper; the higher end of the guide plate is close to the discharge port of the collection hopper, and the lower end is connected to the outlet of the feed cylinder";

[0004] Existing buffer feeding devices have the problem that the buffer angle of rice cannot be adjusted during use. When the rice flow rate or characteristics change, the buffering force cannot be adjusted in time, resulting in poor buffering effect. Secondly, the diversion structure of traditional devices is simple, and the impact force is concentrated when the rice falls, which can easily cause pipe blockage. In addition, the flow guiding components lack buffer protection, and wear and tear is serious after long-term use, resulting in high maintenance costs.

[0005] Therefore, an angle buffer is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an angle buffer, which has the advantages of flexibly adjusting the rice buffering force according to actual working conditions, improving the applicability of the device, not only achieving efficient diversion and buffering of rice and reducing the risk of blockage, but also extending the service life of the flow guiding components and reducing maintenance costs.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an angle buffer, comprising a feed pipe, wherein a flow divider is installed on both inner walls of the feed pipe, and an angle adjustment mechanism is installed on the inner surface of the feed pipe. The angle adjustment mechanism includes two racks, which are slidably connected to the feed pipe. A crossbar is fixedly connected to both racks. A cylinder is fixedly connected to one end of the feed pipe, and the output end of the cylinder is fixedly connected to the crossbar. Three gears are meshed with one end of each of the two racks. A connecting rod is fixedly connected to one end of each of the six gears. One end of each of the six connecting rods passes through the feed pipe and is rotatably connected to one inner wall of the feed pipe. A guide plate is fixedly connected to each of the six connecting rods on the outer surface of the feed pipe.

[0008] Preferably, the flow divider is arc-shaped and located above the six guide vanes.

[0009] Preferably, one end of the feeding tube is provided with an observation window, and the observation window is made of quartz glass.

[0010] Preferably, all six guide vanes are inclined, and the three guide vanes on the same vertical side are staggered with the three guide vanes on the other vertical side.

[0011] Preferably, one end of each of the two racks is provided with a guide groove, and one end of the feed tube is fixedly connected with a guide strip that works in conjunction with the two guide grooves.

[0012] Preferably, a buffer pad is installed at the top of the guide plate, and a plurality of guide grooves are formed at the top of the buffer pad.

[0013] Preferably, the cushioning pad is made of food-grade silicone.

[0014] Preferably, the cross-section of each of the several guide channels is U-shaped, and the inner surface of each of the several guide channels is provided with a lubricating layer.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting an angle adjustment mechanism, uses components such as cylinder, rack, gear and connecting rod to drive the crossbar to move, so that the rack slides and drives the gear to rotate. This allows for precise adjustment of the tilt angle of the guide plate, thereby flexibly adjusting the rice buffering force according to the actual working conditions and improving the applicability of the device.

[0017] 2. This utility model uses an arc-shaped diverting plate and staggered guide plates with buffer pads and guide grooves. The diverting plate initially disperses the rice, and the guide plates provide multi-layer buffering. The buffer pads absorb the impact force, and the guide grooves reduce the friction of the rice. This not only achieves efficient diversion and buffering of rice and reduces the risk of blockage, but also extends the service life of the guide components and reduces maintenance costs.

[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] like Figures 1 to 5 As shown, this utility model provides an angle buffer, including a feed pipe 1, with a diversion plate 41 installed on both inner walls of the feed pipe 1, and an angle adjustment mechanism 4 installed on the inner surface of the feed pipe 1.

[0026] The angle adjustment mechanism 4 includes two racks 44, which are slidably connected to the feeding pipe 1. A crossbar 43 is fixedly connected to both racks 44. A cylinder 42 is fixedly connected to one end of the feeding pipe 1, and the output end of the cylinder 42 is fixedly connected to the crossbar 43. Three gears 45 are meshed with one end of each of the two racks 44. A connecting rod 47 is fixedly connected to one end of each of the six gears 45. One end of each of the six connecting rods 47 passes through the feeding pipe 1 and is rotatably connected to the inner wall of one side of the feeding pipe 1. A guide plate 3 is fixedly connected to the outer surface of each of the six connecting rods 47. The output end of the cylinder 42 drives the crossbar 43 to move, causing the racks 44 to slide and drive the gears 45 to rotate. This allows for precise adjustment of the tilt angle of the guide plate 3, thus flexibly adjusting the rice buffering force according to actual working conditions and improving the applicability of the device.

[0027] Specifically, the diverter plate 41 is arc-shaped and located above the six guide plates 3. The arc-shaped diverter plate 41 can evenly distribute the concentrated falling rice to each guide plate 3, avoiding excessive local impact and extending the service life of the equipment.

[0028] like Figures 1 to 5 As shown, one end of the feed pipe 1 is provided with an observation window 2, which is made of quartz glass. The quartz glass observation window 2 is resistant to high temperature and corrosion and has high transparency, making it easy to observe the rice conveying status in real time and detect abnormalities such as blockages in a timely manner.

[0029] Furthermore, all six guide vanes 3 are inclined, and the three guide vanes 3 on the same vertical side are staggered with the three guide vanes 3 on the other vertical side. The staggered inclined guide vanes 3 form a multi-level buffer structure, which significantly reduces the falling speed of the rice and reduces the impact and wear on the pipeline and downstream equipment.

[0030] like Figures 1 to 5 As shown, each of the two racks 44 has a guide groove 461 at one end, and a guide strip 46 that works with the two guide grooves 461 is fixedly connected to one end of the feed tube 1. The cooperation structure between the guide strip 46 and the guide groove 461 ensures the linear motion accuracy of the rack 44, prevents meshing deviation of the gear 45 and rack 44, and improves the stability and reliability of the angle adjustment mechanism 4.

[0031] It is worth noting that a buffer pad 31 is installed at the top of the deflector plate 3. Several deflector grooves 32 are opened at the top of the buffer pad 31. The buffer pad 31 further absorbs the impact energy of the rice, and the deflector grooves 32 guide the flow of the rice, reducing rice accumulation and splashing, and improving the conveying efficiency.

[0032] like Figures 1 to 5 As shown, the cushioning pad 31 is made of food-grade silicone. Food-grade silicone is safe, non-toxic, elastic, and wear-resistant, and is suitable for the food, pharmaceutical, and other industries, meeting hygiene standards.

[0033] It is worth emphasizing that the cross-section of several guide channels 32 is U-shaped, and the inner surface of several guide channels 32 is provided with a lubricating layer. The U-shaped guide channels 32, together with the lubricating layer, reduce the flow resistance of rice, reduce frictional heat generation, prevent rice from sticking, and ensure the stability of the conveying process.

[0034] The cylinder 42 is existing technology and will not be described in detail. This invention also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this invention is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0035] Working principle and process: Rice enters from the top of the feed pipe 1 and is first dispersed to both sides by the arc-shaped diverter plate 41. When it is necessary to adjust the angle of the guide plate 3, the cylinder 42 is activated first. The cylinder 42 drives the crossbar 43 to drive the two racks 44 to slide linearly along the guide bar 46. The racks 44 rotate the connecting rod 47 through the meshing gear 45, thereby synchronously adjusting the tilt angle of the six guide plates 3. The rice falls with multi-stage buffering on the staggered guide plates 3. The buffer pads 31 and the guide grooves 32 further reduce the impact and guide the flow of rice, ultimately achieving a controllable speed. The rice conveying system, with its adjustable angle, allows for real-time monitoring of the internal conveying status through the observation window 2. The stroke of cylinder 42 is adjusted as needed to change the angle of the guide plate 3, adapting to different rice characteristics and process requirements. For long-grain rice, due to its large length and low surface friction coefficient, it rolls easily; the angle of the guide plate 3 is automatically adjusted to a smaller value to increase the contact time between the rice and the guide plate 3, preventing breakage due to excessive rolling speed. For short-grain rice, due to its short, round shape and high surface friction coefficient, it accumulates easily; the angle of the guide plate 3 is automatically adjusted to a larger value to reduce the rice's residence time and avoid blockage.
