Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a sampling detector for rice processing. Background Technique

[0002] The main detection items of rice are: detection of rice nutritional components, detection of heavy metals in rice, detection of cadmium in rice, detection of moisture in rice, detection of genetically modified rice, detection of rice quality, detection of organic rice, detection of rice freshness, detection of rice toxins, detection of rice mildew, detection of pesticide residues in rice. As people's daily staple food, detection items such as broken rice, imperfect grains, maximum limits of impurities, pesticide residues, moisture, yellow rice grains, admixture, cadmium, arsenic, lead, mercury, etc. are also important items for rice detection.

[0003] In the related technology, the Chinese patent document with the application number CN202322461294.5 proposed a sampling detector for rice processing. By starting the first motor, the output end of the first motor starts to rotate, so that the first motor drives the rotating rod inside the fixed plate to rotate, and the rotating rod drives the auger to rotate. When the rice passes through the limiting cylinder, it will enter the inside of the limiting cylinder from the rice inlet, so that the rice will be driven by the auger to move upward, so that the rice enters the rice inlet groove inside the fixed block, and the rice will move along the rice outlet groove to the storage groove of the storage box above the fixed rod. When the sampling detector needs to be lifted or lowered, through the control panel on the support frame, the two second motors can be operated. Starting the two second motors makes the threaded rods above the second motors rotate, so that the moving blocks can move on the outer surface of the threaded rods, and through the moving grooves, it can prevent the moving blocks from shifting when moving. The two moving blocks drive the lifting plate to move up and down, so as to achieve the purpose that the sampling detector can sample the rice and the sampling detector can be lifted and lowered.

[0004] In view of the above related technology, the inventor believes that there are the following defects: This device can only sample the rice at one position at a time. However, in fact, there will be slight differences in the quality of the rice in each part during the production of the whole batch of rice. Sampling only one group cannot represent the production quality of the whole batch of rice. In view of this, a sampling detector for rice processing is proposed to solve the above problems.

[0007] The adjusting mechanism includes a support frame. A support frame that can move left and right is slidably installed on the lifting plate. A gear is rotatably installed inside the support frame. A rack that meshes with the first gear is fixed on the lifting plate. A first motor for driving the gear to rotate is fixed on one side of the support frame.

[0008] Furthermore, the adjusting mechanism further includes through slots. Two through slots are opened on the lifting plate. A sliding rod is horizontally arranged inside the through slots. Through holes that are slidably matched with the sliding rod are opened on the support frame.

[0009] Furthermore, the lower end of the support frame is fixed to the conveying cylinder. The two through slots are located on both sides of the rack.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 3 and Figure 5 , A sampling detector for rice processing in this embodiment includes two support plates 1. A lifting mechanism 2 is arranged inside the support plates 1. The lifting mechanism 2 is used to lift the lifting plate 3 to facilitate the insertion of the conveying cylinder 7 into the rice. The lifting mechanism 2 can be provided with a rotatable threaded rod vertically arranged inside the two support plates 1, and one end is driven to rotate by an external motor. The two ends of the lifting plate 3 are in threaded cooperation with the two threaded rods, so that the lifting plate 3 can move up and down. A liftable lifting plate 3 is arranged between the two support plates 1. An adjusting mechanism 4 is arranged on the lifting plate 3. A conveying cylinder 7 is arranged on the adjusting mechanism 4. A discharge pipe 6 is fixed on one side of the conveying cylinder 7. A screw conveyor 8 is arranged inside the conveying cylinder 7. A loading mechanism 5 is arranged on the conveying cylinder 7.

[0024] The adjusting mechanism 4 includes a support frame 403. A support frame 403 that can move left and right is slidably installed on the lifting plate 3. A first gear 405 is rotatably installed inside the support frame 403. A rack 406 that meshes with the gear is fixed on the lifting plate 3. A first motor 404 for driving the gear to rotate is fixed on one side of the support frame 403.

[0025] The device starts the first motor 404, and the first motor 404 drives the first gear 405 to rotate. The first gear 405 meshes with the rack 406, causing the support frame 403 to move left and right on the lifting plate 3, thereby adjusting the position of the conveying cylinder 7 to extract rice at different positions.

[0026] Among them, the adjusting mechanism 4 further includes through slots 401. Two through slots 401 are provided on the lifting plate 3. A sliding rod 402 is horizontally arranged in the through slots 401. A through hole that slidably cooperates with the sliding rod 402 is provided on the support frame 403. The two through slots 401 are located on both sides of the rack 406, making the sliding of the sliding rod 402 more stable and avoiding shaking.

[0027] At the same time, the lower end of the support frame 403 is fixed to the conveying cylinder 7, facilitating driving the conveying cylinder 7 to move back and forth left and right.

[0028] Please refer to Figure 1 and Figure 4 In this embodiment, the loading mechanism 5 includes a circular ring 503 and a second motor 501. A circular ring 503 is rotatably installed on the conveying cylinder 7. An external gear ring 505 is fixed above the outer side of the circular ring 503. Connecting rods 506 are fixed to the lower side of the circular ring 503 at equal intervals. A loading box 504 is fixed to one end of the connecting rod 506.

[0029] A second motor 501 is fixed on the support frame 403. The output end of the second motor 501 is fixed with a second gear 502 that meshes with the external gear ring 505.

[0030] The device starts the second motor 501. The second motor 501 drives the second gear 502 to rotate. The second gear 502 meshes with the external gear ring 505. The external gear ring 505 drives the circular ring 503 to rotate, rotating the loaded loading box 504 so that another unloaded rice corresponds to the discharge pipe 6, facilitating the collection of rice at different positions.

[0031] Among them, the loading box 504 is located below the discharge pipe 6, facilitating the rice at the discharge pipe 6 to be discharged into the loading box 504. The second gear 502 is located above the connecting rod 506 to avoid interfering with the rotation of the loading box 504.

[0032] The working principle of the above embodiment is as follows:

[0033] When it is necessary to collect rice at different positions, the first motor 404 can be started to drive the first gear 405 to rotate. The first gear 405 meshes with the rack 406, so that the support frame 403 moves left and right on the lifting plate 3. When adjusted to the appropriate position, the lifting mechanism 2 can drive the lifting plate 3 to descend, so that the conveying cylinder 7 is inserted into the rice. At this time, the screw conveyor 8 is started, and the rice will be driven by the auger 18 to move upward and then discharged through the discharge pipe 6 into the receiving box 504, thus completing the collection.

[0034] Then, the lifting mechanism 2 drives the lifting plate 3 to rise, so that the conveying cylinder 7 is away from the rice. Then, the screw conveyor 8 idles for a while, so that the rice in the auger is completely pushed into the discharge pipe 6 and falls into the receiving box 504.

[0035] Subsequently, when the support frame 403 moves to different positions, the second motor 501 is started to drive the second gear 502 to rotate. The second gear 502 meshes with the external gear ring 505, and the external gear ring 505 drives the ring 503 to rotate, rotating the full receiving box 504 so that another empty rice is corresponding to the discharge pipe 6. Then, the above steps are repeated to extract the rice into the receiving box 504.

[0036] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.
