Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, and in particular relates to an integrated screen removal machine for agricultural use. Background Technology

[0002] In agricultural production, threshing and screening of crops are crucial post-harvest processing procedures. Traditional agricultural operations typically employ a step-by-step process, first using a threshing machine to thresh the crops, and then using a cleaning screen or air separator to screen them. This segmented approach suffers from problems such as large equipment footprint, cumbersome procedures, low production efficiency, and high energy consumption, making it difficult to meet the demands of modern agricultural production for efficient and integrated operations.

[0003] Existing seed screening equipment still faces a series of pressing technical problems in practical applications: The existing seed screening frames are typically fixed, making disassembly and cleaning extremely inconvenient during crop replacement or equipment maintenance, severely impacting continuous operation efficiency and hygiene; simultaneously, the fixed sieve openings of the screening device cannot be flexibly adjusted, making it difficult to meet the screening needs of different types and sizes of seeds, resulting in inaccurate screening, limited applicability, and affecting the final seed purity and quality. Therefore, we provide an integrated agricultural seed screening machine to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated screening and desieving machine for agricultural use to solve the above-mentioned problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an integrated threshing and screening machine for agricultural use, including a machine body and a seed threshing frame installed at the upper port of the machine body; the seed threshing frame is equipped with an auxiliary frame with both ends rotating through the side walls of the seed threshing frame; the upper and lower parts of the auxiliary frame are bolted to a seed screening frame; a seed threshing roller is located between the two sets of seed screening frames; the two ends of the seed threshing roller rotate through the sleeves at both ends of the auxiliary frame; a counterweight is fixed to one end of the seed screening frame outside the seed threshing frame and sleeved on the shaft of the seed threshing roller; a human-shaped flow divider is installed inside the machine body; a movable screen with both ends passing through the side wall of the machine body is set on one side of the human-shaped flow divider; a positioning screen is set at the lower end of the movable screen; and a suction fan is fixed on the side wall of the machine body on the other side of the human-shaped flow divider.

[0007] The present invention is further configured such that the upper and lower sets of seed screening frames are arranged in a cylindrical structure, and the left and right openings of the two sets of seed screening frames are respectively set as the feeding part and the discharging part. A conveyor installed on the side wall of the machine body is provided at the feeding part, and an inclined plate installed on the seed threshing frame is provided at the discharging part.

[0008] The present invention is further configured such that a rotating groove is provided on the upper part of the outer wall of the seed threshing frame, a rotating cover is provided inside the rotating groove, an anti-detachment cover is fixed on the surface wall of the seed threshing frame above the feeding section, and an anti-splash cover is fixed on the surface wall of the seed threshing frame above the discharging section.

[0009] The present invention is further configured such that a converging frame is bolted inside the body above the human-shaped diverter plate, and the lower end of the converging frame is located directly above the movable screen.

[0010] The present invention is further configured such that a reduction motor connected to the seed threshing roller is fixed on the outer wall of the machine body located below the conveyor, and a universal wheel frame is installed on the lower end face of the machine body.

[0011] The present invention is further configured such that the bifurcated parts at the lower end of the human-shaped diverter plate pass through the openings on the side wall of the machine body, and the two ends of the movable screen and the positioning screen pass through the openings on the side wall of the machine body.

[0027] Example

[0028] Please see Figures 1 to 6This utility model is an integrated threshing and screening machine for agriculture, including a body 1 and a seed threshing frame 3 installed at the upper port of the body 1. The body 1 serves as the main structure of the entire equipment, supporting and accommodating other components and providing a stable working environment. The seed threshing frame 3, installed at the upper port of the body 1, is used for threshing and preliminary screening of crops. Inside the seed threshing frame 3, there is an auxiliary frame 37 that rotates through both sides of the frame. The auxiliary frame 37 supports the seed screening mesh frame 38 and the seed threshing roller 39, enabling them to rotate and ensuring the stability of threshing and screening. The upper and lower parts of the auxiliary frame 37 are bolted to the seed screening mesh frame 38. The two sets of seed screening mesh frames 38 are used to screen seeds during the threshing process, separating the straw from the seeds. The seed threshing roller 39 is positioned between the two sets of seed screening mesh frames 38. As the seed threshing roller 39 rotates between the two sets of seed screening mesh frames 38, it separates the seeds from the crops, thus achieving seed threshing. The two ends of the roller 39 rotate through the sleeve positions at both ends of the auxiliary frame 37. One end of the seed sieve frame 38, located outside the seed threshing frame 3, is fixed with a counterweight 304 sleeved on the shaft of the seed threshing roller 39. The counterweight 304 is used to provide a balancing torque to prevent the auxiliary frame 37 from unexpectedly following the rotation of the seed threshing roller 39. A human-shaped diverter plate 13 is installed inside the machine body 1 to divert the seeds entering the machine body 1, causing the threshed seeds to fall off. At the upper end of the movable sieve 6, a movable sieve 6 is provided on one side of the human-shaped diverter plate 13, with both ends passing through the side wall of the body 1. A positioning sieve 61 is provided at the lower end of the movable sieve 6. The use of the movable sieve 6 and the positioning sieve 61 can adjust the size of the mesh between them. A suction fan 2 is fixed on the side wall of the body 1 on the other side of the human-shaped diverter plate 13. The suction fan 2 can suck away light impurities and purify the seeds. A suction fan 2 is fixed on the side wall of the body 1 on the other side of the human-shaped diverter plate 13.

[0029] It should be noted that the suction fan 2 adopts a frequency conversion structure, which can adjust the airflow of the suction fan 2 according to the type of crop being screened. At the same time, a filter screen is installed at the air intake of the suction fan 2 to block the entry of impurities.

[0030] The two sets of seed sieve frames 38 are cylindrical in structure. The left and right openings of the two sets of seed sieve frames 38 are respectively set as the feeding section and the discharging section. The feeding section is equipped with a conveyor 4 installed on the side wall of the machine body 1. The conveyor 4 is used to transport the crop into the seed threshing frame 3, reducing the burden of manual feeding. The discharging section is equipped with an inclined plate 36 installed on the seed threshing frame 3. When the seed threshing roller 39 is working, it will rotate the straw to the top position of the space inside the auxiliary frame 37 and discharge it from the discharging section. The inclined plate 36 is used to guide the straw out of the seed threshing frame 3. The upper part of the outer wall of the seed threshing frame 3 has an opening. The rotating trough 35 has a rotating cover 33 inside. Rotating the rotating cover 33 in the position of the rotating trough 35 opens the top position of the seed threshing frame 3, thereby allowing the auxiliary frame 37 to be rotated and the seed screening frame 38 to be rotated to the position of the rotating trough 35, which facilitates the disassembly of the seed screening frame 38. The seed threshing frame 3 above the feeding section has an anti-drop cover 31 fixed to its surface wall to prevent the crop from falling off or overflowing during feeding. The seed threshing frame 3 above the discharging section has a splash guard 32 fixed to its surface wall to prevent the material from splashing during discharging and to keep the working environment clean.

[0031] Specifically, a converging frame 11 is bolted inside the body 1 above the human-shaped diverter plate 13. The converging frame 11 gathers the seeds screened by the seed sieve frame 38, causing the seeds to fall onto the upper end of the movable sieve 6. The lower end of the converging frame 11 is directly above the movable sieve 6. A reduction motor 5 is fixed on the outer wall of the body 1 below the conveyor 4 and is connected to the seed threshing roller 39. When the reduction motor 5 is working, it will drive the seed threshing roller 39 to rotate in the auxiliary frame 37.

[0032] The bifurcated portions at the lower end of the humanoid diverter plate 13 all pass through openings on the side wall of the machine body 1. The two ends of the movable screen 6 and the positioning screen 61 also pass through openings on the side wall of the machine body 1. Two sets of vibrating frames 62, connected to the inner wall of the machine body 1 and the outer wall of the humanoid diverter plate 13, are installed at the lower end of the positioning screen 61 that protrudes from the machine body 1. An eccentric unit 64, mounted on the outer wall of the machine body 1, is located below one end of the positioning screen 61 that protrudes from the machine body 1. The eccentric unit 64 includes an eccentric motor, an eccentric wheel, and guide bars. The eccentric unit 64 drives the positioning screen 61 to vibrate, achieving high... For effective screening, locking bolts 63 are provided on the upper end of the movable screen 6 on the same side as the eccentric unit 64. The locking bolts 63 are screwed on so that they abut against the positioning screen 61, making the movable screen 6 unable to move on the positioning screen 61. The locking bolts 63 abut against the upper end face of the positioning screen 61. A side inclined plate 14 installed on the outer wall of the machine body 1 is provided at the lower position of the other end of the positioning screen 61 that passes through the machine body 1. Larger impurities at the upper end of the movable screen 6 are guided to fall onto the side inclined plate 14 and are recycled.

[0033] Furthermore, a caster frame 12 is installed on the lower end face of the machine body 1. The caster frame 12 facilitates the movement and positioning of the equipment and enhances its flexibility.

[0034] The operation process of this embodiment is as follows: First, the crop is fed into the feeding section of the seed threshing frame 3 through the conveyor 4. The seed threshing roller 39 rotates under the drive of the reduction motor 5 to thresh the crop, so that the seeds and straw are separated. The threshed seeds fall through the mesh of the seed sieve frame 38, while the straw is rotated to the discharge section and discharged by the inclined plate 36. The fallen seeds are collected by the collection frame 11 and fall onto the movable screen 6.

[0035] Subsequently, the eccentric unit 64 drives the positioning screen 61 to vibrate, which in turn drives the movable screen 6 to vibrate synchronously. By adjusting the locking bolt 63, the relative positions of the movable screen 6 and the positioning screen 61 can be fixed, and the size of the screen holes can be controlled to achieve graded screening of seeds of different particle sizes. At the same time, the suction fan 2 is started to suck away light impurities, improve the purity of the seeds, and as the movable screen 6 works, the larger impurities at the top of the movable screen 6 are discharged along the side inclined plate 14, while the light impurities sucked away by the suction fan 2 are discharged from the other side of the human-shaped diversion plate 13. After the movable screen 6 and the positioning screen 61 screen the seeds, the seeds will be discharged from the human-shaped diversion plate 13 directly below.
