Description

Technical Field

[0001] The invention relates to the technical field of wheat breeding, and in particular to a multifunctional wheat seed screening and medicine mixing device. Background Art

[0002] Wheat seed treatment is a key link in agricultural production, directly affecting seed germination rate, disease resistance and crop yield. The traditional seed treatment process usually includes steps such as cleaning, grading, and seed dressing with pesticides. However, existing technologies still have significant deficiencies in screening efficiency, thoroughness of impurity removal, and uniformity of drug mixing. There is an urgent need for technology to improve treatment effects and production efficiency.

[0003] Traditional wheat screening mostly relies on static screens or single vibrating screens, which makes it difficult to efficiently separate wheat of different particle sizes or impurities (such as straw, dust, empty grains, etc.). Static screening is prone to clogging of the screen holes due to material accumulation, reducing processing speed. Although ordinary vibrating screens can improve fluidity, their structural design is simple and cannot achieve fast and uninterrupted processing.

[0004] Seed pesticide treatment requires ensuring that the drug is in full contact with the wheat to achieve disease prevention, insect repellent and other effects. Existing drug mixing devices mostly use single-axis stirring or simple spraying methods, which can easily cause uneven drug distribution: on the one hand, gravity causes the drug to tend to accumulate at the bottom of the equipment or in local areas; on the other hand, a single drug supply direction makes it difficult to cover all grain surfaces. In addition, insufficient mixing time or improper intensity of the drug and seed will also aggravate the uneven mixing problem, affecting the efficacy of the drug and increasing the cost of the drug.

[0005] Therefore, the present invention provides a multifunctional wheat seed screening and medicine mixing device to solve the above problems. Summary of the Invention

The stirring shaft 11 is located inside the medicine mixing chamber 3, as shown in the attached figure. Figure 5 As shown, a dosing component 8 is provided inside the mixing chamber 3, and a bidirectional screw 4 is rotatably connected inside the screening chamber 2. The bidirectional screw 4 is driven and connected to the mixing motor 9 through a transmission box 6. The transmission box 6 is located on the outer wall of the outer box 1, and the bidirectional screw 4 matches the screening plate 5. The screening plate 5 is hinged inside the screening chamber 2; the device can enable the screening plate 5 to screen the wheat on its outer wall through the cooperation of the screening plate 5 and the bidirectional screw. At the same time, the screening plate 5 performs reciprocating displacement to achieve vibration and extrusion screening to ensure the thoroughness of the screening. At the same time, it is convenient to mix the wheat during extrusion, and the screening is more convenient and thorough. The screened wheat can be automatically mixed with medicine, and under the action of the extrusion and stirring shaft 11, it can ensure that the wheat and the medicine are fully mixed. The dosing component 8 of the device can automatically feed up and down to ensure uniform dosing, avoid the accumulation of medicines, and prevent the phenomenon of excessive local medicine when the wheat is stirred and mixed.

[0044] As attached Figure 3 As shown, a right-angled threaded plate 401 is threadedly connected to the outer wall of the bidirectional screw 4, and the outer wall of the right-angled threaded plate 401 is against one end face of the screening plate 5, and a sealing rubber 501 is fixedly installed on one end face of the top of the screening plate 5, and the other end of the sealing rubber 501 is fixedly connected to the side wall of the screening chamber 2, and a return spring 502 is fixedly installed on the other end face of the bottom of the screening plate 5, and the other end of the return spring 502 is fixedly connected to one end face of the filter plate 7; in the initial state of the screening plate 5 of this device, the filter holes on the outer wall are in a sealed state, which can prevent wheat from falling through the holes and avoid the discharge of wheat when it is not screened, thereby ensuring smooth screening. When the screening is completed, impurities or large grains of wheat remain inside, which are discharged by opening the filter holes.

When screening is needed, the mixing motor 9 is started to drive the bidirectional screw 4 to rotate, and the right-angled threaded plate 401 performs reciprocating displacement. When the right-angled threaded plate 401 is displaced to the right end, the right-angled threaded plate 401 will hit the screening plate 5, causing the screening plate 5 to be squeezed and the angle to change. The wheat inside will pass through the filter plate 7 and enter the interior of the mixing chamber 3, and When the angle of the screening plate 5 changes, the driving tooth plate 503 will mesh with the driving gear 205. The width of the driving tooth plate 503 of the device is large.

The wheat accumulated at its bottom will be rolled over, and the telescopic plate 203 can always keep against the outer wall of the filter plate 7. When the right-angle threaded plate 401 is reset, the screening screw 201 rotates in the opposite direction. The tumbling plate 202 is displaced, and the screening plate 5 is reset under the action of the reset spring 502. The reciprocating action of the right-angle threaded plate 401 can drive the device to perform continuous extrusion filtration. At the same time, the tumbling plate 202 is continuously rolled to ensure the thoroughness of wheat screening. The wheat at the bottom is tumbled up and down for filtration to avoid accumulation in a certain area and inadequate filtration. At the same time, the extrusion filtration can be carried out continuously to ensure uninterrupted filtration, which can avoid inadequate screening and missed screening.
