Description

Technical Field

[0001] This utility model belongs to the field of color sorting machine technology, and in particular relates to a grain color sorting machine. Background Technology

[0002] Color sorters are devices that automatically separate discolored particles from granular materials based on differences in their optical properties using photoelectric detection technology. They are commonly used for screening grains.

[0003] Existing grain color sorters may mis-sort or miss grains due to dust and impurities on the grain surface, affecting the sorting effect. In view of this, we propose a new grain color sorter. Utility Model Content

[0004] The purpose of this invention is to provide a grain color sorter to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a grain color sorter, comprising:

[0006] The base has two fixed plates fixedly installed on its top surface. A screening machine is arranged between the two fixed plates. The bottom surface of the screening machine is fixedly connected to the top surface of the base. A first mounting plate is fixedly installed on the top surface of the two fixed plates. A fixing frame is fixedly installed on the top surface of the first mounting plate. A feed pipe is fixedly installed on the top surface of the fixing frame. A guide pipe is fixedly installed on the bottom surface of the feed pipe. A guide plate is arranged below the guide pipe. The outer side wall of the guide plate is slidably connected to the inner side wall of the fixing frame.

[0007] The second mounting plate is fixedly installed on the top surface of the first mounting plate. A fixing rod is fixedly installed on the top surface of the second mounting plate. A sliding block is slidably installed on the outer side wall of the fixing rod. The top surface of the sliding block is fixedly connected to the bottom surface of the guide plate. Two discharge pipes are fixedly installed on the top surface of the base. The top surfaces of the two discharge pipes are fixedly connected to the outer side wall of the screening machine.

[0008] A sliding plate is provided below the guide pipe. The bottom surface of the sliding plate is fixedly connected to the outer wall of the screening machine, and the outer wall of the sliding plate is fixedly connected to the inner wall of the first mounting plate.

[0009] A drive assembly is disposed on a second mounting plate and is used to drive the guide plate to vibrate;

[0010] A feeding assembly is disposed below the base.

[0011] In the above technical solution, the driving component further includes a fixed block, which is fixedly installed on the outer side wall of the sliding block. A movable block is rotatably installed inside the fixed block. A first disc is fixedly installed on one side of the movable block. A mounting frame is fixedly installed on the top surface of the second mounting plate. A rotating rod is rotatably installed inside the mounting frame. A second disc is fixedly installed on one side of the rotating rod. The same connecting rod is fixedly installed between the second disc and the first disc.

[0012] In this technical solution, when the second disc rotates, the first disc is pulled to swing by the connecting rod, which causes the sliding block to slide up and down on the fixed rod, driving the guide plate to vibrate. Due to the high-frequency vibration of the guide plate, the grain on the guide plate can be evenly spread to prevent the accumulation and blockage.

[0013] In the above technical solution, the drive assembly further includes a first gear, which is fixedly installed on the outer side wall of the rotating rod. A first motor is fixedly installed on the top surface of the second mounting plate, and a second gear is fixedly installed at one end of the output shaft of the first motor. The second gear meshes with the first gear.

[0014] In this technical solution, the first motor is started, which drives the second gear to rotate. The second gear meshes with the first gear, thereby driving the rotating rod to rotate, ensuring the stability of the grain color sorter's operation.

[0015] In the above technical solution, the feeding assembly further includes a feeding box, which is fixedly installed on one side of the bottom surface of the base. The feeding box is connected to one of the discharge pipes. A first feeding auger is rotatably installed inside the feeding box. A support plate is fixedly installed on one side of the feeding box. A second motor is fixedly installed on the top surface of the support plate. One end of the output shaft of the second motor passes through one side of the feeding box and is fixedly connected to one end of the first feeding auger. A connecting pipe is fixedly installed on the other side of the feeding box.

[0016] In this technical solution, substandard grains will enter another discharge pipe through the screening machine and fall into the feeding box through the other discharge pipe. At this time, the second motor is started, which drives the first feeding auger to rotate, transporting the substandard grains to the first installation pipe through the connecting pipe.

[0017] In the above technical solution, the feeding assembly further includes a first mounting tube, which is fixedly mounted on the base and connected to a connecting tube. A second feeding auger is rotatably mounted inside the first mounting tube. A support frame is fixedly mounted on the bottom surface of the base. A third motor is fixedly mounted on the top surface inside the support frame. The top end of the output shaft of the third motor passes through the bottom end of the first mounting tube and is fixedly connected to the bottom end of the second feeding auger. A discharge port is opened on the outer wall of the sliding plate, and the top end of the first mounting tube is connected to the discharge port.

[0018] In this technical solution, the third motor is started, which drives the second feeding auger to rotate. The second feeding auger transfers the grain in the connecting pipe to the discharge port and back to the sliding plate. The grain then enters the screening machine again through the sliding plate for a second round of screening. This process is repeated multiple times to prevent mis-selection or omission.

[0019] In the above technical solution, further, an installation box is fixedly installed on the bottom surface of the base. The installation box is located below another discharge pipe. A collection box is slidably installed inside the installation box. The collection box is connected to another discharge pipe. A handle is fixedly installed on one side of the collection box. A retaining sleeve is fixedly installed on one side of the collection box. A limit hole is opened on one side of the installation box. The same limit rod is movably connected between the retaining sleeve and the limit hole.

[0020] In this technical solution, qualified grains will fall into the collection box through one of the discharge pipes. After the collection box is full, the worker will pull out the limit rod to release the limit on the collection box, pull the handle to pull out the collection box, and reset it after emptying the collection box.

[0021] In the above technical solution, furthermore, multiple support legs are fixedly installed on the bottom surface of the base.

[0022] This technical solution provides more reliable support for the overall equipment.

[0023] The beneficial effects of this utility model are:

[0024] 1. In use, the grain color sorter involves the worker first pouring grain into the feed pipe. The grain flows into the guide plate through the guide pipe below the feed pipe. At this time, the first motor is started, driving the second gear to rotate. The second gear meshes with the first gear, thereby driving the rotating rod to rotate. When the second disc rotates, it pulls the first disc to swing through the connecting rod, causing the sliding block to slide up and down on the fixed rod, which in turn causes the guide plate to vibrate. Due to the high-frequency vibration of the guide plate, the grain on the guide plate can be evenly spread out to prevent accumulation and blockage. The grain falls onto the sliding plate with the vibration and finally enters the screening machine for screening.

[0025] 2. In this grain color sorter, after screening, qualified grains fall into a collection box through one of the discharge pipes. Once the collection box is full, the worker pulls out the limit rod to release the limit on the collection box, pulls the handle to pull out the collection box, and resets it after emptying it. Unqualified grains enter the screening machine through another discharge pipe and fall into a feeding box. At this time, the second motor is started, which drives the first feeding auger to rotate, transporting the unqualified grains through the connecting pipe to the first installation pipe. Then, the third motor is started, which drives the second feeding auger to rotate, transferring the grains in the connecting pipe to the discharge port and back to the sliding plate. The grains then re-enter the screening machine through the sliding plate for a second round of screening. This process is repeated multiple times to prevent mis-screening or missed screening. After multiple screenings, the screening machine is turned off, and the worker uses the feeding mechanism to transport the unqualified grains to the collection box for processing.
