DETAILED DESCRIPTION
[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0026] A safflower threshing device, such as Figures 1-6 As shown, the threshing machine includes a threshing machine body 1, an air collection box 2, and a baffle plate 3 installed on one side of the air collection box 2; a collection box 4 is movably installed inside the air collection box 2; the collection box 4 is inserted into the air collection box 2, and a top plate 404 is installed above the two side plates 401 located outside the air collection box 2; a screen 408 is installed obliquely inside the collection box 4; a ventilation slot 407 matching the air outlet of the threshing machine body 1 is opened on one side plate 401 of the collection box 4; slots are opened on the inner walls of the two side plates 401 of the collection box 4, and insert plates 413 are movably installed in the slots, with a gap between the lower end of the insert plate 413 and the upper surface of the screen 408.
[0027] Compared to existing devices, a larger collection box 4 is designed, with one part of the collection box 4 inserted into the air collecting box 2 with an open top, and the other part outside the air collecting box 2, equipped with a top plate 404, and an insert plate 413 inserted into the inner cavity of the collection box 4. When the threshing machine body 1 is working, the blown air enters the air collecting box 2, and is discharged from the rear side by the obstruction of the baffle plate 3 and the insert plate 413. The airflow blows the crushed straw and other debris to the rear side; the grains fall onto the screen 408 below and move along the surface of the screen 408 to one end of the inner cavity of the collection box 4. In addition, the screen 408 can also filter out immature small grains and fine powder. This utility model can solve the problem of the original collection box being too small and requiring frequent removal without damaging the existing device, simply by replacing the original collection box with the newly designed collection box 4. It can improve work efficiency and effectively filter immature small grains and fine powder. The threshing machine body 1 is an existing purchased device, specifically the DR-2 type threshing machine sold by Zhengzhou Deren Electronic Technology Co., Ltd.
[0028] To facilitate the assembly and disassembly of the screen 408, a support block 409 for supporting the screen 408 is fixedly connected to the back plate 402 of the collection box 4; one end of the screen 408 is mounted on the support block 409, and the other end rests against the bottom plate 403 of the collection box 4.
[0029] A vibrator 414 is installed at the bottom of the screen 408. The vibrator 414 can be a miniature electric motor or a pneumatic vibrator. When the vibrator 414 is turned on during operation, it can drive the screen 408 to vibrate, which can accelerate the movement of the grains and promote the falling of fine grains or straw.
[0030] The fixed plate 415 is fixed in the collecting box 4; the fixed plate 415 is located directly below the plug plate 413, and the top of the fixed plate 415 is in abutment with the bottom of the screen 408. The fixed plate 415 supports the screen 408 and blocks the airflow to the extension of the collecting box 4.
[0031] The upper limiting block 5 and the lower limiting block 6 are fixed on the inner wall of the two sides of the air collecting box 2; the cross section of the upper limiting block 5 is in the shape of “L”; during operation, the back plate 402 of the collecting box 4 is in abutment with the upper limiting block 5 and the lower limiting block 6, and the upper edge of the back plate 402 is in contact with the inner wall of the upper limiting block 5, as shown in the figure. The upper limiting block 5 and the lower limiting block 6 limit the position of the collecting box 4, preventing the position from being improper when the collecting box 4 is pushed into the air collecting box 2, so that the ventilation groove 407 cannot be aligned with the ventilation opening on the air collecting box 2. Figure 3
[0032] In order to facilitate the collection of the grains, the movable plate 405 is rotatably installed between the lower parts of the two side plates 401 through a pin shaft; the movable plate 405 is fixed with the baffle 406 at both ends; the limiting holes 412 are formed in the corresponding positions of the two baffles 406 and the side plates 401; the position of the movable plate 405 in the closed state can be locked by inserting the limiting rod into the limiting hole 412. When the collected grains need to be taken out, the movable plate 405 can be opened after the top plate 404 is removed.
[0033] In order to enable the movable plate 405 to rotate to the same inclination angle as the screen 408, the two side plates 401 of the collecting box 4 are extended to beyond the bottom plate 403; the triangular limiting block 410 is fixed on the inner wall bottom of the two side plates 401 of the collecting box 4; when the movable plate 405 is in the open state, the movable plate 405 is in contact with the triangular limiting block 410. The triangular limiting block 410 can prevent the movable plate 405 from rotating completely downward to the vertical state under the action of the weight.
[0034] The bottom outer edge of the movable plate 405 is provided with a round corner; the upper surface of the bottom plate 403 located below the movable plate 405 is provided with an avoiding groove; when the movable plate 405 is in the closed state, the lower end of the movable plate 405 is in contact with the top surface of the avoiding groove.
[0035] The fixed frame 8 is installed on the top of the back of the air collecting box 2. The clamp 7 is installed on the top and the outer side of the air collecting box 2. During operation, the net bag is sleeved on the fixed frame 8, and the bag opening of the net bag is clamped by the clamp 7.
[0036] In order to facilitate the disassembly and assembly of the top plate 404, the T-shaped groove is formed on the upper surface of the two side plates 401 of the air collecting box 2; the T-shaped sliding block is fixed on the lower surface of the two ends of the top plate 404 and is in sliding connection with the T-shaped groove.
[0037] In another embodiment, the two side plates 401 of the wind collecting box 2 are fixed with fixing blocks on the inner wall of the upper part; the top plate 404 is detachably installed on the side plate by screws.
[0038] The working principle of the utility model is as follows:
[0039] When working, the mesh bag is sleeved outside the fixing frame 8, and the bag opening is clamped by the clamp 7. The threshing machine body 1 is opened. When the threshing machine body 1 works, the wind is blown into the wind collecting box 2, and the crushed straw and other sundries are blown out to the rear side; the seeds are dropped on the lower screen 408 and moved to the inner cavity end of the collecting box 4 along the screen 408 surface. In addition, the screen 408 can also filter out small seeds and fine powder. When the collecting is completed, the collecting container is placed at a proper position. The threshing machine body 1 is closed, the top plate 404 is removed, the limiting rod inserted in the limiting hole 412 is pulled out, the movable plate 405 is pulled to rotate until the movable plate 405 is rotated to be loaded on the triangular limiting block 410. At this time, the collected seeds can continue to move downward along the screen 408 and the movable plate 405 and fall into the collecting container. After the seeds are taken out, the screen 408 can be taken out according to the situation, and the small seeds and fine sundries filtered out are cleaned.
[0040] The utility model can replace the original collecting box with the newly designed collecting box 4 without damaging the existing device, solve the problem that the original collecting box is too small and needs to be frequently taken out, improve the work efficiency, and filter out small seeds and fine powder.
[0041] The embodiments of the utility model are described in detail in combination with the drawings, but the utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the utility model, and still fall within the protection scope of the utility model.
