Technical Field
[0001] This utility model relates to the field of rice processing technology, specifically to a dual gravity rice separator for rice processing that can prevent external force impact. Background Technology
[0002] The gravity paddy rice separator is a device that separates paddy rice by utilizing the differences in specific gravity, particle size, and surface friction coefficient between them, and by using a bi-directionally inclined, reciprocating working plate to automatically classify and separate the paddy rice. The dual-gravity paddy rice separator is an upgraded version of the gravity paddy rice separator.
[0003] For example, the public document with application number 202121786011.9 discloses a dual-gravity rice separator for rice processing that can prevent external impact. This utility model is equipped with a base, a protective plate, a dust collection box, a stepper motor, a screw, a dual-gravity rice separator body, an external pipe, a dust suction head, a feeding hopper, a spring, a buffer plate, a waste discharge pipe, a discharge pipe, a screw block, a dust collector, a hose, and a second pipe. It solves the problems of poor protection effect of traditional dual-gravity rice separators, inability to prevent external impact, and inconvenience in dust removal during operation. However, when protecting the machine body, this device only uses a single spring for buffering. After the spring is hit, although it can use its own elastic contraction force to buffer the impact to a certain extent, the spring itself is not stable, resulting in reciprocating vibration. This causes the entire buffer plate to swing back and forth, which not only makes it difficult to effectively buffer and weaken the impact, but also aggravates the shaking and vibration of the entire machine body, thus making it difficult to effectively protect against external impact.
[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a dual gravity rice separator for rice processing that can prevent external force impact. Utility Model Content
[0005] The purpose of this invention is to provide a dual-gravity rice separator for rice processing that can prevent external impact, in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a dual-gravity rice separator for rice processing that can prevent impact from external forces, comprising a machine body, a feeding port installed on the upper surface of the machine body, a discharge port installed on the lower surface of the machine body, damping spring rods evenly distributed and fixedly installed around the surface of the machine body, the damping spring rods being composed of a damper and a telescopic spring, the end of the damping spring rods on the same side of the machine body away from the machine body being fixedly installed with the same protective plate, and grooves evenly distributed around the surface of the machine body, each groove containing an auxiliary buffer mechanism.
[0007] Preferably, the auxiliary buffer mechanism includes a guide rod fixedly installed on the inner surface of the groove, and damping sliders are slidably sleeved on both the upper and lower sides of the guide rod. Thrust springs are fixedly installed on the opposite side of the surface of the damping sliders, and the end of the thrust spring away from the damping slider is fixedly connected to the inner surface of the groove.
[0008] Preferably, the auxiliary buffer mechanism further includes a movable rod rotatably connected to the side of the damping slider surface near the groove opening, and the end of the movable rod away from the damping slider is rotatably connected to the protective plate via the same pivot seat.
[0009] Preferably, the interior of the protective plate is hollow, and an air intake box is fixedly installed on the lower side of the inner surface of the protective plate.
[0010] Preferably, a sealing frame is inserted into the upper side of the inner surface of the protective plate, and the periphery of the sealing frame is tightly fitted to the inner surface of the protective plate.
[0011] Preferably, an air groove is formed in the middle of the surface of the sealing frame, and a filter element is fixedly installed on the lower surface of the sealing frame.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model, through the arrangement of a damping spring rod, a protective plate, a groove, an auxiliary buffer mechanism, a guide rod, a damping slider, a thrust spring, and a movable rod, allows the protective plate to contact the impacting object first when the machine body is subjected to a collision. The resulting impact force causes the protective plate to move to one side of the machine body, which in turn squeezes the damping spring rod. The characteristics of the damper are used to buffer the collision. At the same time, as the protective plate moves, the movable rod pushes the damping slider to move up and down along the guide rod. During the movement of the damping slider, the thrust spring is also squeezed and contracted, thereby generating a reverse elastic force in the thrust spring. Under the buffering effect of the sliding damping effect of the damping slider and the reverse elastic force of the thrust spring, the collision can be buffered a second time. When the entire machine body is subjected to a collision, it can effectively buffer and weaken the impact generated by the collision, thereby greatly reducing the damage caused by external impact forces to the machine body, enabling the machine body to work more stably and be used more safely.
[0014] 2. This utility model, through the arrangement of an air suction box, a sealing frame, an air groove, and a filter element, activates the air suction box when rice is added. The air suction box draws air from around the feeding port through the air groove, causing the surrounding air to move downwards through the air groove and into the protective plate. At this time, the air carrying dust will be filtered by the filter element, intercepting all the dust and then expelling clean air. The dust will adhere to the filter element, and the filter element can be directly pulled out for replacement using the sealing frame, thereby greatly avoiding dust pollution generated during the feeding process.

[0019] 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.
[0020] like Figures 1-3 As shown, a dual-gravity rice separator for rice processing that can prevent impact from external forces includes a body 1. A feeding port 2 is installed on the upper surface of the body 1, and a discharge port 3 is installed on the lower surface of the body 1. Damping spring rods 4 are evenly distributed and fixedly installed around the surface of the body 1. The damping spring rods 4 are composed of a damper and a telescopic spring. The end of the damping spring rods 4 on the same side of the body 1 away from the body 1 is fixedly installed with the same protective plate 5. Grooves 6 are evenly distributed around the surface of the body 1, and auxiliary buffer mechanisms 7 are set inside the grooves 6.
[0021] By adopting the above technical solution, when the body 1 is hit by a collision, the protective plate 5 will make priority contact with the collision object, thereby avoiding direct collision damage to the body 1.
[0022] The impact force will cause the protective plate 5 to move towards the body 1, and the protective plate 5 will squeeze the damping spring rod 4, using the characteristics of the damper to buffer the collision.
[0023] Furthermore, the auxiliary buffer mechanism 7 includes a guide rod 701 fixedly installed on the inner surface of the groove 6. A damping slider 702 is slidably sleeved on both the upper and lower sides of the surface of the guide rod 701. A thrust spring 703 is fixedly installed on the opposite side of the surface of the damping slider 702. The end of the thrust spring 703 away from the damping slider 702 is fixedly connected to the inner surface of the groove 6.
[0024] The auxiliary buffer mechanism 7 also includes a movable rod 704 that is rotatably connected to the side of the surface of the damping slider 702 near the opening of the groove 6. The end of the movable rod 704 away from the damping slider 702 is rotatably connected to the protective plate 5 via the same pivot seat.
[0025] By adopting the above technical solution, when the protective plate 5 moves, the movable rod 704 will also push the damping slider 702 to move up and down along the guide rod 701. During the movement of the damping slider 702, the thrust spring 703 will be compressed and contracted, thereby generating a reverse elastic force in the thrust spring 703. Under the buffering effect of the sliding damping of the damping slider 702 and the reverse elastic force of the thrust spring 703, the collision can be buffered a second time.
[0026] Furthermore, the interior of the protective plate 5 is hollow, and an air intake box 8 is fixedly installed on the lower side of the inner surface of the protective plate 5.
[0027] By adopting the above technical solution, the suction box 8 can form a downward airflow around the entire feeding port 2, so that the dust generated during feeding will settle downward.
[0028] Furthermore, a sealing frame 9 is inserted into the upper side of the inner surface of the protective plate 5, and the periphery of the surface of the sealing frame 9 is tightly fitted with the inner surface of the protective plate 5.
[0029] An air groove 10 is provided in the middle of the surface of the sealing frame 9, and a filter element 11 is fixedly installed on the lower surface of the sealing frame 9.
[0030] By adopting the above technical solution, the air suction box 8 draws air from the surrounding area of the feeding port 2 through the air groove 10, so that the surrounding air moves downward through the air groove 10 into the interior of the protective plate 5. At this time, the air carrying dust will be filtered by the filter element 11, which will intercept all the dust and then discharge the clean air. The dust will stick to the filter element 11, and the filter element 11 can be directly pulled out for replacement using the sealing frame 9, thereby greatly avoiding dust pollution generated during the feeding process.
[0031] The sealing frame 9 ensures a tight fit with the protective plate 5 on all sides, preventing dust leakage from the seams.
[0032] Working Principle: When using this dual-gravity rice separator designed to prevent external impacts, the suction box 8 is activated when material is added through the feeding port 2. The suction box 8 draws air from around the feeding port 2 through the air groove 10, causing the surrounding air to move downwards through the air groove 10 and into the protective plate 5. At this time, the dust-laden air is filtered by the filter element 11, intercepting all the dust and allowing clean air to be discharged. The dust adheres to the filter element 11, preventing dust from flying and polluting the working area. The filter element 11, after prolonged use, can be directly removed and replaced through the sealing frame 9. When the machine body 1 is impacted, the protective plate 5 is the first to contact the impacting object. The resulting impact force causes the protective plate 5 to move to one side of the machine body 1. When the protective plate 5 moves, it will squeeze the damping spring rod 4, using the characteristics of the damper to buffer the collision. At the same time, when the protective plate 5 moves, it will also use the movable rod 704 to push the damping slider 702 to move up and down along the guide rod 701. During the movement of the damping slider 702, it will also squeeze the thrust spring 703 to contract, thereby causing the thrust spring 703 to generate a reverse elastic force. Under the buffering effect of the sliding damping of the damping slider 702 and the reverse elastic force of the thrust spring 703, the collision can be buffered a second time. When the entire machine body 1 is subjected to a collision, it can effectively buffer and weaken the impact generated by the collision, thereby greatly reducing the damage caused by the external impact force to the machine body 1. This is the working principle of the dual gravity rice separator for rice processing that can prevent the impact of external forces.
