Description

Technical Field

[0001] The utility model relates to the technical field of grain detection instruments, in particular to a multi-grain feeding control system. Background Art

[0002] Grain detection instruments usually have a feeding module, which is directly related to the speed, position, quantity, shape and other parameters of grain feeding. These parameter information has a great impact on whether the subsequent grain can be detected normally, and even directly affects the final parameters. Therefore, the control of the grain feeding module is particularly important.

[0003] The feeding modules in existing grain detection instruments usually have the following problems:

[0004] (1) The capacity of a single test is limited.

[0005] The commonly used feeding mechanism uses a circular vibrator or a linear vibrator to feed the material. In grain testing instruments, the vibrator is usually not very large due to the size, convenience and other requirements of grain testing instruments. The size of the vibrator is directly related to the number of test samples. Therefore, when a large number of test samples are required, a larger grain testing instrument may be used, which increases the cost; or a solution of adding small amounts multiple times can be used, but it also requires continuous human involvement, which is time-consuming and labor-intensive.

[0006] (2) The feeding quantity is not controlled and the best feeding effect cannot be achieved.

[0007] The vibrator can store a certain amount of samples, and can achieve feeding within the maximum detection amount. However, there is an optimal detection amount or optimal detection range within the maximum detection and feeding range. In the current technical solution, it is difficult to accurately measure the feeding amount, and the feeding amount is added arbitrarily, which cannot achieve the best feeding effect, and the detection effect also fluctuates randomly and is difficult to evaluate. Utility Model Content

[0008] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the utility model is to propose a multi-grain feeding control system, which can store a large amount of grains to be tested at a time, can achieve accurate feeding according to the best feeding effect, can effectively improve the detection effect, and has low cost and high work efficiency.

[0009] The multi-grain feeding control system according to the embodiment of the utility model comprises:

[0010] A storage hopper, wherein the storage hopper is used to store grains;

[0011] A material distribution module, the material distribution module comprises a material distribution base, at least three paddles, a rotating shaft and a driving unit; the top and bottom of the material distribution base are respectively provided with a feed port and a discharge port, the material distribution base is arranged below the storage hopper and the feed port is connected to the lower end of the storage hopper; the material distribution base has a hollow cavity with a horizontally extending central axis, the rotating shaft is installed in the hollow cavity concentrically with the hollow cavity, at least three paddles are located in the hollow cavity and are evenly fixed on the rotating shaft along the circumferential direction of the rotating shaft; the driving unit is arranged outside the material distribution base and connected to the rotating shaft to drive the rotating shaft to rotate;

[0012] A discharge hopper, the discharge hopper is arranged below the material distribution module, and the upper end of the discharge hopper is connected to the discharge port;

[0013] A vibrating plate is arranged below the discharge hopper and is used to receive the grains sliding down the discharge hopper and convey the grains to the detection line in a single-layer and single-row discharge order.

[0014] The working process of the multi-grain feeding control system of the embodiment of the utility model is as follows: manually or automatically add the grains to be tested into the storage hopper, and since at least three of the paddles in the material distribution base can block the feed port and the discharge port of the material distribution base when they are at any angle, the feed port and the discharge port cannot be directly vertically connected, so that the grains remain in the storage hopper and can directly fall from the feed port into the fan-shaped space with the opening facing upward or the opening partially facing upward, but cannot directly fall vertically from between the feed port and the discharge port and pass through the discharge port. As the driving unit drives the paddle to rotate, the opening of the fan-shaped space receiving the grains rotates to the discharge port, and the grains flow out of the discharge port by gravity, and slide into the vibration plate through the discharge hopper. By controlling the start and pause of the driving unit, it can be ensured that the amount of grain in the vibration plate is always within the optimal detection amount or the optimal detection range. Under suitable vibration frequency and voltage conditions, the grain particles are arranged in a single layer on the spiral track, and the grain particles are introduced into the detection line in a single-layer and single-row order.

[0015] In summary, according to the multi-grain feeding control system of the embodiment of the utility model, by setting the storage hopper, a large amount of grains to be tested can be stored, the number of times of adding grains can be reduced, and the efficiency can be improved; by setting the material distribution module, on the one hand, the outlet at the lower end of the storage hopper can be actively closed to avoid leakage under abnormal conditions of the multi-grain feeding control system, and on the other hand, the discharge quantity and discharge speed can be accurately controlled, and intermittent feeding can be achieved to ensure that the amount of grains in the vibration disk is always in the optimal detection amount or the optimal detection range. The vibration disk vibrates under appropriate vibration frequency and voltage conditions, so that the grain particles are arranged in a single layer on the spiral track, and the grain particles are introduced into the detection line according to the single-layer single-row discharge order. As a result, the feeding control system of the embodiment of the utility model realizes the single storage of a large amount of grain samples to be tested, can realize accurate feeding according to the best feeding effect, can effectively improve the detection effect, and is suitable for a variety of grains such as corn, soybeans, wheat, etc. The multi-grain feeding control system of the embodiment of the utility model has low cost and high work efficiency.

[0016] In some embodiments, a detector is further included, wherein the detector is used to detect the amount of grain in the vibration plate to control the start and stop of the driving unit.

[0018] In some embodiments, the photoelectric sensor is mounted on the lower end of the discharge hopper.

[0019] In some embodiments, the hollow cavity is circular.

DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] Combine the following Figures 1 to 4 To describe the multi-grain feeding control system 1000 of an embodiment of the present utility model.

[0035] like Figures 1 to 4 As shown, the multi-grain feeding control system 1000 according to the embodiment of the utility model includes a storage hopper 1, a material distribution module 2, a discharge hopper 3 and a vibration plate 4.

[0036] The storage hopper 1 is used to store grains. The grains stored in the storage hopper 1 are generally grains to be tested, and the grains to be tested can be corn, soybeans, wheat, etc. When testing is required, the grains to be tested are added to the storage hopper 1. The storage hopper 1 can be made larger according to actual use requirements, and can store a larger amount of grains to be tested, reducing the number of times to add grains and improving efficiency.

[0037] The material distribution module 2 includes a material distribution base 201, at least three paddles 202 (such as Figure 1 The three paddles are shown in the figure. Figure 4 201, four paddles are shown), a rotating shaft 204 and a driving unit 205. The top and bottom of the material distribution base 201 are respectively provided with a feed inlet and a discharge inlet. The material distribution base 201 is arranged below the storage hopper 1 and the feed inlet is connected to the lower end of the storage hopper 1. In this way, the grains stored in the storage hopper 1 can directly and automatically fall into the material distribution base 201 from the lower end of the storage hopper 1 through the feed inlet. The material distribution base 201 has a hollow cavity with a central axis extending horizontally, and the rotating shaft 204 is installed in the hollow cavity concentrically with the hollow cavity, that is, the rotating shaft 204 is coaxial with the hollow mold part, and at least three paddles 202 are located in the hollow cavity and are evenly fixed on the rotating shaft 204 along the circumferential direction of the rotating shaft 204. In this way, a fan-shaped space is formed between two adjacent paddles 202, and at least three paddles 202 can form at least three fan-shaped spaces correspondingly. For example, three paddles 202 can form three fan-shaped spaces, and four paddles 202 can form four fan-shaped spaces. Since at least three paddles 202 are evenly distributed along the circumferential direction of the rotating shaft 204, at least three fan-shaped spaces are substantially the same, and when at least three paddles 202 rotate at any angle following the rotating shaft 204, they can block the feed port and the discharge port of the material distribution base 201, that is, the grains cannot fall directly vertically between the feed port and the discharge port, but can only fall from the feed port into the fan-shaped space with the opening facing upward or the opening partially facing upward. As the rotating shaft 204 rotates, the opening of the fan-shaped space receiving the grains rotates to the discharge port, and the grains flow out of the discharge port under the action of gravity. The driving unit 205 is arranged outside the material distribution base 201 and connected to the rotating shaft 204 to drive the rotating shaft 204 to rotate, so that at least three paddles 202 can rotate synchronously with the rotating shaft 204. By driving the rotating shaft 204 with the driving unit 205, the grains can be input from the feed port to the discharge port for discharge. Thus, the material dispensing module 2 can accurately control the discharging quantity and discharging speed, and can realize intermittent feeding. According to the grain size and feeding control accuracy, the number of paddles 202 can be increased, which is equivalent to reducing the minimum division value of measurement, and the measurement is more accurate.

[0038] The discharge hopper 3 is arranged below the material distribution module 2 , and the upper end of the discharge hopper 3 is connected to the discharge port; this ensures that the grains discharged from the material distribution module 2 can slide down along the discharge hopper 3 .

[0039] The vibration plate 4 is arranged below the discharge hopper 3, and is used to receive the grains sliding down the discharge hopper 3, and convey the grain particles to the detection line 6 in a single-layer single-row discharge order. It should be noted that the inner wall of the vibration plate 4 has a spiral track, and the vibration plate 4 vibrates and disperses the grain particles in the vibration plate 4 under appropriate vibration frequency and voltage conditions, so that the grain particles are fed along the spiral track in a single layer, and the grain particles are conveyed to the detection line 6 in a single-layer single-row discharge order to improve the detection effect. Since the above-mentioned material distribution module 2 can accurately control the discharge quantity and discharge speed, intermittent feeding can be achieved, therefore, it can be ensured that the amount of grain in the vibration plate 4 is always in the optimal detection amount or the optimal detection range, and the grain particles on the spiral track are always arranged in a single layer.

[0040] The working process of the multi-grain feeding control system 1000 of the embodiment of the utility model is as follows: manually or automatically add the grains to be tested into the storage hopper 1, because at least three paddles 202 in the material distribution base 201 can block the feed port and the discharge port of the material distribution base 201 when they are at any angle, so that the grains remain in the storage hopper 1 and can fall from the feed port into the fan-shaped space with the opening facing upward or the opening partially facing upward, and cannot fall directly vertically between the feed port and the discharge port. As the driving unit 205 drives the paddle 202 to rotate, the opening of the fan-shaped space receiving the grains rotates to the discharge port, and the grains flow out of the discharge port by gravity, and slide into the vibration plate 4 through the discharge hopper 3. By controlling the start and pause of the driving unit 205, it can be ensured that the amount of grain in the vibration plate 4 is always within the optimal detection amount or the optimal detection range. Under the appropriate vibration frequency and voltage conditions, the grain particles are arranged in a single layer on the spiral track, and the grain particles are introduced into the detection line 6 in a single-layer and single-row order.

[0041] In summary, according to the multi-grain feeding control system 1000 of the embodiment of the utility model, by setting the storage hopper 1, a large amount of grains to be tested can be stored, the number of times of adding grains can be reduced, and the efficiency can be improved; by setting the material distribution module 2, on the one hand, the outlet at the lower end of the storage hopper 1 can be actively closed to avoid the phenomenon of leakage under the abnormal condition of the multi-grain feeding control system 1000, and on the other hand, the discharge quantity and discharge speed can be accurately controlled, and intermittent feeding can be realized to ensure that the amount of grains in the vibration plate 4 is always in the optimal detection amount or the optimal detection range. The vibration plate 4 vibrates under the appropriate vibration frequency and voltage conditions, so that the grain particles are arranged in a single layer on the spiral track, and the grain particles are introduced into the detection line 6 according to the single-layer single-row discharge order. Therefore, the feeding control system of the embodiment of the utility model realizes the single storage of a large amount of grain samples to be tested, can realize accurate feeding according to the best feeding effect, can effectively improve the detection effect, and is suitable for a variety of grains such as corn, soybeans, wheat, etc. The multi-grain feeding control system 1000 of the embodiment of the utility model has low cost and high work efficiency.

[0042] In some embodiments, Figure 1 and Figure 4 As shown, a detector 5 is also included, and the detector 5 is used to detect the amount of grains in the vibration plate 4 to control the start and pause of the driving unit 205. That is, the detector 5 cooperates with the driving unit 205 to ensure that the amount of grains in the vibration plate 4 is the optimal detection amount, which is conducive to the grains in the vibration plate 4 being arranged in a single layer on the spiral track under the vibration of the vibration plate 4.

[0043] Specifically, the detector 5 detects the amount of grain in the vibration plate 4. When there is no grain or less grain in the vibration plate 4 (a material threshold a can be set in advance according to the actual situation, and the material is less than a at this time), the detector 5 is triggered and transmits a signal to the drive unit 205 of the material distribution module 2 (such as the motor 2051 of the drive unit 205), so the drive unit 205 starts and drives the paddle 202 to rotate. The grain in the material distribution module 2 is gradually discharged into the vibration plate 4. When the material on the vibration plate 4 gradually increases and reaches the material threshold a, the detector 5 stops sending information, the drive unit 205 pauses, and the material distribution module 2 stops unloading.

[0044] The vibration plate 4 is in working state throughout the whole process and has nothing to do with the signal of the detector 55. The materials in the vibration plate 4 are sent out in a single layer and a single row. When the amount of grain is less than a, the detector 5 is triggered, the material distribution module 2 is started, and grains are added to the vibration plate 4 until the amount of grains in the vibration plate 4 reaches a.

[0045] Therefore, by setting the start and stop thresholds of the detector 5, the amount of grain in the vibration plate 4 can be controlled to achieve the best vibration feeding state.

[0046] In some embodiments, the detector 5 is a photoelectric sensor or a distance sensor, which is suspended above the vibration plate 4. The photoelectric sensor can accurately detect the amount of grains in the vibration plate 4, and the photoelectric sensor cooperates with the driving unit 205 to achieve closed-loop control to adjust the amount of grains in the vibration plate 4 to be within the optimal detection range, which is conducive to making the grains in the vibration plate 4 distributed in a single layer on the spiral track under the vibration of the vibration plate 4.

[0047] In some embodiments, the photoelectric sensor is installed on the lower end of the discharge hopper 3. Therefore, the photoelectric sensor is easy to install and can accurately detect the amount of grains in the vibration plate 4.

[0048] In some embodiments, the hollow cavity is circular, has a reasonable design, and is easy to process.

[0049] In some embodiments, the material dispensing module 2 further includes a paddle seat 203, which is fixed on the rotating shaft 204. The paddle seat 203 has at least three paddle 202 mounting positions that are evenly spaced along the circumferential direction, and at least three paddles 202 are mounted one by one on the at least three paddle 202 mounting positions. By providing the paddle seat 203, at least three paddles 202 can be easily assembled with the rotating shaft 204.

[0050] In some embodiments, at least three paddles 202 are flexible paddles 202, that is, all paddles 202 are flexible paddles 202. The flexible paddles 202 themselves have a certain degree of flexibility. When there is material between the flexible paddles 202 and the material distribution base 201 during the rotation process, the rotating shaft 204 will continue to rotate due to the large torque, so the flexible paddles 202 will bend and deform to avoid squeezing the sample and causing damage to the grain particles to be tested.

[0051] In some embodiments, at least three radial outer edges of the paddles 202 are provided with sawtooth structures, which can further improve the flexibility of the paddles 202 and protect the grain samples to be tested. Specifically, the size of the sawtooth structure can be designed according to the size of the grain particles, which can further improve the flexibility of the paddles 202 and protect the grains to be tested.

[0052] In some embodiments, the maximum distance between the radial outer edges of two adjacent paddles 202 is less than or equal to the height of the material distribution base 201. In this way, when at least three paddles 202 rotate at any angle following the rotating shaft 204, they can block the feed port and the discharge port of the material distribution base 201.

[0053] In some embodiments, the driving unit 205 includes a motor 2051 and a transmission assembly 2052, wherein the transmission assembly 2052 is connected between the motor 2051 and the rotating shaft 204. When the motor 2051 rotates, the transmission assembly 2052 is driven to move, and the transmission assembly 2052 drives the rotating shaft 204 to rotate.

[0054] In some embodiments, the transmission assembly 2052 is a belt transmission assembly. Figure 2 As shown, the belt transmission assembly includes two pulleys 20521 and a belt 20522. The two pulleys 20521 are respectively mounted on the motor shaft and the rotating shaft 204, and the belt 20522 is wound around the two pulleys 20521. When the motor 2051 rotates, the belt 2052 transmission assembly 2052 is driven to rotate, thereby driving the rotating shaft 204 and the paddle 202 to rotate.
