Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, and in particular to a rapid grain and weed sorting device. Background Technology

[0002] During the harvesting and subsequent processing of grain, impurities such as weeds, bran, and dust inevitably get mixed in. These impurities not only affect the quality and storage period of the grain, but also cause wear and tear on subsequent processing equipment. Therefore, efficient sorting is a key step in grain processing.

[0003] Currently, the sorting of weeds in grains mainly uses single screening or air separation technology. Single screening technology can only separate small dust particles, and its screening effect is limited for weeds and straws that are similar in size to grain particles and have irregular shapes. As for single air separation equipment, it generally blows impurities up to separate them from the grain, which generates a lot of dust during the sorting process.

[0004] Therefore, based on the above situation, we designed a rapid grain and weed sorting device to solve the above problems. Utility Model Content

[0005] This invention provides a rapid grain and weed sorting device to solve the problems in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A rapid grain and weed sorting device includes a support frame, a screening component, and a dust cover. The support frame has a first guide groove and a second guide groove. The screening component is slidably connected to the first guide groove. The support frame is provided with a first driving component, which drives the screening component to reciprocate along the first guide groove to screen impurities inside the grain. The dust cover is slidably connected to the second guide groove. The interior of the dust cover is provided with a blower mechanism for blowing up impurities on the surface of the grain and a suction mechanism for collecting the impurities blown up by the blower mechanism. The support frame is provided with a second driving component for driving the dust cover to reciprocate along the second guide groove.

[0008] Preferably, the blower assembly includes a blower, an air supply duct connected to the output end of the blower, and an air outlet connected to the air supply duct. The air outlet faces the screening component and is set at an angle to the plane of the screening component.

[0009] Preferably, the ventilation mechanism includes a ventilation fan, a ventilation duct connected to the input end of the ventilation fan, and a ventilation hood connected to the ventilation duct.

[0010] Preferably, the dust cover is provided with a flexible curtain.

[0011] Preferably, the output end of the exhaust fan is connected to a collection box for collecting impurities via a feeding pipe, and the inner bottom surface of the collection box is an inclined surface that gradually slopes towards the outlet of the collection box.

[0012] Preferably, the screening component is detachably connected to a discharge plate.

[0013] The beneficial effects of this utility model are as follows: by placing grain on the screening component, the first driving component moves the screening component to reciprocate, thereby screening out particles, dust and other impurities inside the grain. At the same time, bran, weeds and other impurities float above the grain. The blower mechanism blows up the weeds and other impurities, and the exhaust mechanism then directly removes them. The efficient collaboration between the various components improves the efficiency of impurity removal and the sorting speed. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] Reference Figures 1-5 As shown, a rapid grain and weed sorting device includes a support frame 1, which supports the entire device. The support frame 1 has a first guide groove 2 and a second guide groove 3. A screening component 4 is slidably connected inside the first guide groove 2. Grain to be sorted is placed inside the screening component 4. A first driving component 5 is provided on the support frame 1. When the first driving component 5 is activated, it drives the screening component 4 to reciprocate along the first guide groove 2. The reciprocating motion of the screening component 4 causes the grain inside to shake, gradually screening out dust and small particles to the bottom of the screening component 4. Meanwhile, impurities such as weeds, bran, and straw gradually float to the surface of the grain. The first driving component 5 can be an electric telescopic rod, a hydraulic telescopic rod, etc., and can be equipped with a controller to adjust the speed of its reciprocating motion. When the screening component 4 processes grains of different particle sizes, such as wheat and corn, the controller adjusts the reciprocating frequency of the first driving component 5 in real time to match the screening rhythm with the grain flow speed, so as to avoid impurity residue or grain loss due to fixed speed. In addition, the size of the screening mesh of the screening component 4 is not limited. In actual use, the appropriate screening mesh can be selected according to different grains.

[0023] During the grain screening process driven by the first drive component 5 and the screening component 4, a dust cover 7 is slidably connected in the second guide groove 3 to remove weeds, bran, straw, etc. floating on the grain surface. The dust cover 7 is equipped with a blower mechanism 8 and an exhaust mechanism 9. When in use, the second drive component 6 on the support frame 1 drives the dust cover 7 to reciprocate along the second guide groove 3. At the same time, the exhaust mechanism 9 and the blower mechanism 8 are turned on. When the blower mechanism 8 blows up the impurities on the grain surface, the dust cover 7 blocks the floating impurities to prevent them from spreading. At the same time, the exhaust mechanism 9 extracts the impurities to remove them. The second drive component 6 can be an electric telescopic rod, a hydraulic telescopic rod, etc. The reciprocating frequency of the second drive component 6 can be adjusted by the controller to blow up and remove impurities at different positions. It works in synergy with the screening process driven by the first drive component 5 to improve the impurity removal efficiency and sorting speed.

[0024] Reference Figure 5As shown, the blower assembly 8 further includes a blower 81, an air supply duct 82 connected to the output end of the blower 81, and an air outlet 83 connected to the air supply duct 82. The blower 81 can be a centrifugal fan, an axial flow fan, or other equipment. By starting the blower 81, the blower 81 supplies air into the air supply duct 82 and blows it out through the air outlet 83. The air outlet 83 can be flat. The flat air outlet 83 can transform the circular airflow output by the blower 81 into a flat "air curtain". The flat air curtain can form a consistent wind speed distribution along the width of the grain layer, ensuring that impurities in all areas of the grain layer surface are blown up with equal force. At the same time, the air outlet 83 faces the screening component 4 and is set at an angle to the plane where the screening component 4 is located. The vibration generated by the reciprocating motion of the screening component 4 will loosen the grain particles. The angled airflow takes the opportunity to penetrate into the gaps between the particles and blow up the dust and light impurities hidden in the grain pile.

[0025] Reference Figure 3 , Figure 5 As shown, the exhaust mechanism 9 further includes an exhaust fan 91, an exhaust duct 92 connected to the input end of the exhaust fan 91, and an exhaust hood 93 connected to the exhaust duct 92. The exhaust fan 91 can be a centrifugal exhaust fan 91, an axial flow exhaust fan 91, etc. By turning on the exhaust fan 91, a negative pressure is generated in the exhaust duct 92, and the impurities blown by the blower mechanism 8 are drawn away through the exhaust hood 93. In addition, the parameters of the exhaust fan 91 can be set by the controller to prevent its suction from being too strong and sucking away the grain.

[0026] The output end of the exhaust fan 91 is connected to a collection box 12 for collecting impurities via a feeding pipe 11. The sucked-out impurities are collected into the inside of the collection box 12. When the inside of the collection box 12 is full of impurities, the opening of the collection box 12 is opened to facilitate the removal of impurities. Then the impurities move along the inclined inner bottom of the collection box 12 outlet to the outlet, thus facilitating the removal of impurities.

[0027] Reference Figure 1 As shown, a flexible curtain 10 is further provided on the dust cover 7. The flexible curtain 10 can be made of materials such as rubber and silicone. When the air outlet 83 blows the screening surface and causes dust to be raised, the flexible curtain 10 can form a "soft barrier" at the opening of the cover to further prevent the dust from overflowing directly and complete the collection in conjunction with the exhaust fan 91.

[0028] Reference Figure 2 , Figure 5As shown, after the grain screening is completed, the grain needs to be removed from the screening component 4. A discharge plate 13 is detachably connected to the screening component 4. The discharge plate 13 can be detachably connected to the screening component 4 by means of snap-fit ​​or locking. When in use, the discharge plate 13 is installed on the screening component 4, forming an integral screening structure with the screening component 4. When it is necessary to remove the grain from the screening component 4, the discharge plate 13 is removed, and the grain falls out from the hole at the position of the discharge plate 13. The grain can be manually gathered, or the screening component 4 can be shaken by turning on the first drive component 5 to improve the collection efficiency.
