Description

Technical Field

[0001] This utility model relates to the field of grain deawning technology, specifically a small deawning machine. Background Technology

[0002] The main impact of awn removal machines in barley or rice experiments lies in improving sample purity, ensuring experimental accuracy, and increasing detection efficiency. By removing awns from barley or branches, impurities, and broken grains from rice, awn removal machines ensure that the samples used have high representativeness and consistency, avoiding interference from impurities in the determination of indicators such as germination rate, thousand-grain weight, and hulling rate in rice. The presence of impurities can not only lead to weight deviations but also affect the repeatability and reliability of experiments, and even damage detection equipment, affecting the normal progress of experiments. The use of awn removal machines can save time and effort in manual screening, enabling rapid processing of large numbers of samples, thereby greatly improving work efficiency. In addition, removing impurities can reduce experimental errors, improve data accuracy, and make experimental results more scientific and comparable. During use, operators need to check the equipment in advance and adjust the parameters to adapt to different varieties and humidity levels of barley or rice to ensure optimal awn removal. During operation, rice grains should be fed evenly into the machine, and parameters should be adjusted after the machine starts running to ensure thorough awn removal without breaking the barley or rice. After processing, the equipment should be cleaned and maintained in a timely manner to ensure its normal operation.

[0003] As disclosed in the patent announcement CN221046647U, a novel rice seed deawning machine includes a processing box. Support legs are fixedly connected to the left and right sides of the processing box, and a feed inlet is fixedly connected to the top of the processing box. An awning removal mechanism is installed inside the processing box, and a material distribution mechanism is installed inside the support legs. The awning removal mechanism includes a stirring assembly and a screening assembly. The stirring assembly and the screening assembly are both located inside the processing box. The stirring assembly continuously stirs the rice, and the stirring rods move and collide between the rice grains, effectively removing the awns. The rice and awns are separated, and then the separated rice and awns are screened out through a set screening plate. However, in the above technical solution, the stirring component, screening component and distributing mechanism each require a motor to drive them. The whole machine is large, and each motor needs to be purchased separately. In particular, high-quality, high-power motors are expensive. Therefore, the total cost of purchasing multiple motors is significantly higher than the solution of using a few motors or centralized drive. Moreover, the high purchase and maintenance costs limit the popularization and promotion of awn removal machines in barley experiments, especially in some areas with limited economic conditions, making it difficult for users to afford. Utility Model Content

[0004] The purpose of this invention is to provide a small deawning machine. A motor drives an adjustable kneading feeding assembly in the feeding box to break up the grain raw material. At the same time, part of the rotational power of the motor is also transmitted to the gathering and deawning assembly in the feeding box through the adjustable kneading feeding assembly and the sprocket transmission structure. This allows the awns of the grain raw material to be removed before entering the deawning box and the gathering and deawning assembly. After being processed by the adjustable kneading feeding assembly and the gathering and deawning assembly, the grain raw material falls into the distribution frame. The driven blower assembly blows away the awns, dust and other impurities in the grain. The deawned grain raw material is discharged through the distribution frame, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a small deawning machine, comprising a frame, a deawning box fixed inside the frame, a feeding box installed at the top of the deawning box, and an adjustable kneading feeding assembly installed inside the feeding box. A gathering-type deawning assembly is installed inside the deawning box, and a sprocket drive structure for power transmission is installed between the gathering-type deawning assembly and the adjustable kneading feeding assembly. A material distribution frame is installed at the lower opening of the deawning box. A driven blower assembly for supplying airflow into the material distribution frame is installed on one outer wall of the frame. The driven blower assembly and the gathering-type deawning assembly are connected by a power source. A motor for driving the adjustable kneading feeding assembly is installed on one outer wall of the feeding box. A control panel electrically connected to the motor input is installed on one side of the frame surface.

[0006] Preferably, inclined guide plates are fixed on both inner walls of the top opening of the feeding box. The adjustable kneading feeding assembly includes a cylinder installed on the inner wall of the feeding box below the inclined guide plates, a C-shaped frame fixed to the top of the cylinder piston rod, and an auxiliary grinding roller rotatably installed on one side of the C-shaped frame. A main grinding roller is rotatably installed inside the feeding box on one side of the auxiliary grinding roller. One end of the main grinding roller is fixedly connected to the top of the drive shaft of the feeding box through a coupling. Hollowed-out portions are provided on both the front and rear inner walls of the C-shaped frame. The other end of the main grinding roller drives the shaping and de-awning assembly to work through a sprocket transmission structure.

[0007] Preferably, the awn removal assembly includes a drive shaft rotatably installed inside the awn removal box, a plurality of protruding arms installed in a ring at equal intervals on the outer wall of the drive shaft, and a rubber plate fixed between two adjacent protruding arms in the Y-axis direction. One end of the drive shaft extends to the outside of the awn removal box and is poweredly connected to the main roller through a sprocket transmission structure.

[0008] Preferably, a number of steel columns are installed in a ring-shaped, equally spaced array on the inner wall of the awn box outside the drive shaft.

[0009] Preferably, the driven blower assembly includes a centrifugal fan mounted on the outer wall of one side of the distribution frame and a belt speed-increasing transmission structure installed between the centrifugal fan drive shaft and the transmission shaft to maintain power transmission.

[0010] Preferably, an air inlet duct is installed on the side of the material distribution frame near the centrifugal fan, a discharge duct is provided inside the material distribution frame below the air inlet duct, and an upwardly extending waste discharge duct is provided on the other side of the material distribution frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This small deawning machine uses a motor to drive the adjustable kneading feeding assembly in the feeding box to start working, so as to break up the grain raw material. At the same time, part of the rotational power of the motor is also transmitted to the gathering and deawning assembly in the feeding box through the adjustable kneading feeding assembly and the sprocket transmission structure. This allows the awns of the grain raw material to be removed before entering the deawning box and the gathering and deawning assembly. After being processed by the adjustable kneading feeding assembly and the gathering and deawning assembly, the grain raw material falls into the distribution frame. The driven blower assembly blows away the awns, dust and other impurities in the grain. The deawned grain raw material is discharged through the distribution frame. The gathering and deawning assembly, the adjustable kneading feeding assembly and the driven blower assembly share the rotational power of a single motor, thereby reducing the number of motors required for the deawning machine and the purchase and operating costs, making it easier to popularize and promote in barley experiments. The rotational power of the motor is used to drive the grain raw material through the sprocket transmission structure. The force is transmitted to the adjustable kneading feeding assembly in the feeding box to achieve pretreatment of the grains. The advantage of this step is that the grains are kneaded and adjusted before entering the deawning box, which helps to loosen the grains, reduce adhesion and accumulation, and ensure the smooth progress of the subsequent deawning process. The gathering deawning assembly in the deawning box can effectively break up the grain raw materials and remove the awns. When the grains are mechanically processed, the awns are peeled off from the surface of the grains, thereby reducing the awn residue rate and improving the deawning efficiency. Furthermore, the processed grains fall into the distribution frame, and with the use of the driven blower assembly, the awns, dust and other impurities in the grains can be effectively blown away. The introduction of the wind blowing mechanism enhances the thoroughness and cleanliness of deawning. By combining mechanical breaking and wind blowing, the quality and efficiency of deawning are greatly improved. It is easy to operate, highly efficient, and can quickly process a large number of samples, making it convenient for users to conduct germination tests, thousand-grain weight, hulling rate and other determinations.

[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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] Please see Figure 1-6 This utility model provides an embodiment of a small deawning machine, including a frame 1, a deawning box 2 fixed inside the frame 1, a feeding box 3 installed at the top of the deawning box 2, and an adjustable kneading feeding assembly 4 installed inside the feeding box 3. A gathering deawning assembly 9 is installed inside the deawning box 2. A sprocket drive structure 406 for power transmission is installed between the gathering deawning assembly 9 and the adjustable kneading feeding assembly 4. A material distribution frame 6 is installed at the lower opening of the deawning box 2. A driven blower assembly 7 for feeding air into the material distribution frame 6 is installed on one side of the outer wall of the frame 1. The driven blower assembly 7 and the gathering deawning assembly 9 are connected by power. A motor 5 for driving the adjustable kneading feeding assembly 4 is installed on one side of the outer wall of the feeding box 3. A control panel 8 electrically connected to the input terminal of the motor 5 is installed on one side of the surface of the frame 1. The control panel 8 controls the motor 5 to work according to the set direction, speed, angle, and response time.

[0021] Inclined guide plates 301 are fixed on both inner walls of the top opening of the feed box 3. The adjustable kneading feeding assembly 4 includes a cylinder 402 installed on the inner wall of the feed box 3 below the inclined guide plates 301, a C-shaped frame 403 fixed to the top of the piston rod of the cylinder 402, and an auxiliary grinding roller 404 rotatably installed on one side inside the C-shaped frame 403. A main grinding roller 401 is rotatably installed inside the feed box 3 on one side of the auxiliary grinding roller 404. One end of the main grinding roller 401 is fixed to the top of the drive shaft of the feed box 3 by a coupling. The C-shaped frame 403 has a hollowed-out part 405 on both the front and rear inner walls. The hollowed-out part 405 provides the C-shaped frame 403 with a movement margin, so as to avoid the main grinding roller 401 from hindering the movement of the C-shaped frame 403 and the auxiliary grinding roller 404. The other end of the main grinding roller 401 drives the awn-removing assembly 9 to work through the sprocket transmission structure 406. The kneading of the grain raw material by the main grinding roller 401 and the auxiliary grinding roller 404 can effectively break up the sticky awns, making them easier to detach from the grain surface and reducing the difficulty of subsequent awn removal.

[0022] The operator activates cylinder 402 via control panel 8. Cylinder 402 pulls C-port frame 403 and auxiliary roller 404 closer to or further away from main roller 401 to adjust the distance between main roller 401 and auxiliary roller 404. This allows the operator to adjust the kneading intensity according to the moisture content, particle size, and burr condition of the raw material.

[0023] Example 2, based on Example 1, is... Figure 2 , Figure 4 , Figure 5 and Figure 6 The awn removal assembly 9 includes a drive shaft 901 rotatably installed inside the awn removal box 2, a number of protruding arms 902 installed in a ring at equal intervals on the outer wall of the drive shaft 901, and a rubber plate 903 fixed between two adjacent protruding arms 902 in the Y-axis direction. One end of the drive shaft 901 extends to the outside of the awn removal box 2 and is powered by the main roller 401 through the sprocket transmission structure 406. A number of steel columns 904 are installed in a ring at equal intervals on the inner wall of the awn removal box 2 outside the drive shaft 901.

[0024] The drive shaft of the feed box 3 drives the main grinding roller 401 to rotate. The main grinding roller 401 drives the drive shaft 901 to rotate through the sprocket transmission structure 406. Then, the convex arm 902 and the rubber plate 903 rotate around the drive shaft 901. The rubber plate 903 continuously beats the grain raw material falling between the main grinding roller 401 and the auxiliary grinding roller 404. The deawned raw material passes between two adjacent steel columns 904 and enters the distribution frame 6. The remaining awns are completely removed by mechanical peeling, which improves the thoroughness of deawn removal.

[0025] The driven blower assembly 7 includes a centrifugal fan 701 mounted on the outer wall of one side of the distribution frame 6 and a belt speed-increasing transmission structure 702 installed between the drive shaft and transmission shaft 901 of the centrifugal fan 701 to maintain power transmission. An air inlet duct 601 is installed on the side of the distribution frame 6 near the centrifugal fan 701. A discharge duct 602 is provided inside the distribution frame 6 below the air inlet duct 601. An upwardly extending waste discharge duct 603 is provided on the other side inside the distribution frame 6.

[0026] The drive shaft 901 drives the centrifugal fan 701 through the belt speed-increasing transmission structure 702. The air force generated by the centrifugal fan 701 enters the distribution frame 6 through the air inlet duct 601. The strong airflow blows away impurities such as awns and dust from the grain. At this time, the impurities are discharged through the waste discharge duct 603, while the clean grain falls freely and is discharged through the discharge duct 602. The discharged grain can be used by the staff to conduct germination tests, rice thousand-grain weight, hulling rate and other measurements.

[0027] In this embodiment of the application, the power connection is first checked to ensure it is normal, and the motor 5 and control panel 8 are in good condition. It is confirmed that key components such as the feeding box 3, adjustable kneading feed assembly 4, deawn box 2, awn-gathering assembly 9, and driven blower assembly 7 are free from abnormal vibration or damage. Finally, the lubrication of each transmission part is checked to ensure that the sprocket drive structure 406 is adequately lubricated to avoid jamming or abnormal noise during operation. The operator pours the grain raw materials to be processed and used in the experiment into the feeding box 3 and starts the motor 5 through the control panel 8. The motor 5 first drives the adjustable kneading feed assembly 4, which in turn drives the awn-gathering assembly 9 through the sprocket drive structure 406. During this process, the operator can adjust the parameters of the adjustable kneading feed assembly 4 according to the type and moisture content of the grain to effectively break up the grain, remove surface adhesion, and reduce awn adhesion. The grain passes through the adjustable kneading feed assembly 4... The adjusting and kneading feeding assembly 4 evenly feeds the grain into the deawning box 2. During this process, the gathering and deawning assembly 9 starts working, mechanically breaking up and peeling off the awns, gradually removing them from the surface of the grain. After deawning, the grain falls into the distribution frame 6 after passing through the gathering and deawning assembly 9. The driven blower assembly 7 generates a strong airflow to blow away the awns, dust, and other impurities from the grain. The wind force of the driven blower assembly 7 is proportional to the rotation speed of the feeding box 3 and can be adjusted according to actual needs to ensure that impurities are effectively blown away without causing grain loss. The blown-away impurities are carried away by the airflow, while the clean grain raw material, being heavier, falls directly and is discharged through the distribution frame 6. The discharged grain raw material can be used to measure indicators such as germination rate, thousand-grain weight, and hulling rate. After deawning is completed, the machine is stopped. After stopping, the equipment is cleaned to remove residual impurities and grain debris, and the wear of each component is checked to prepare for the next operation.
