Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a wide-narrow row monomer assembly. Background Art

[0002] In the process of modern agricultural mechanization, the development and application of soybean planters are crucial for improving agricultural production efficiency, optimizing crop layout, and increasing yields. Traditional soybean planters, often using fixed row spacing, struggle to meet the diverse demands for row spacing in different regions and soil conditions. This limitation is particularly pronounced when implementing wide- and narrow-row planting patterns, making it difficult to precisely control row spacing, which in turn affects the crop's growth environment and ultimate yield.

[0003] To address these issues, soybean planters with adjustable row spacing have gradually emerged on the market. However, these devices often suffer from complex structures, difficult adjustments, and poor stability. Especially for wide- and narrow-row planting patterns, how to quickly and accurately adjust row spacing while ensuring the planter's overall stability and operating efficiency has become a pressing technical challenge. Utility Model Content

[0004] The purpose of the utility model is to provide a wide and narrow row monomer assembly that can provide narrow row sowing and has accurately adjustable sowing row spacing in order to solve the above problems.

[0005] In order to achieve the above-mentioned purpose, the utility model discloses a wide and narrow row single body assembly of a soybean seeder, comprising a long frame installed at the rear of a frame, a sowing device installed at the rear of the long frame, and its structural features are: a short frame is installed at the rear of the frame, the short frame is located on the side of the long frame, a slider is installed at the front end of the short frame, an adjustment seat is fixedly installed at the rear of the frame, the slider is slidably installed in the adjustment seat and can move left and right, a screw is rotatably installed on the adjustment seat, the screw passes through the slider and cooperates with the slider thread, and a handwheel for rotating the screw is installed on the screw.

[0006] A short frame is installed at the rear of the vehicle frame and is designed to move left and right. The sliding fit of the slider in the adjustment seat and the threaded transmission between the lead screw and the slider enable precise adjustment of the seeding row spacing. This allows for flexible adjustment of the seeding row spacing, meeting the needs of wide and narrow row planting patterns.

[0007] A connecting beam is fixed to the front end of the short frame. This square tubular beam extends vertically, and a slider is mounted within it. The slider's left and right movement within the adjustment base allows for flexible adjustment of the seeding row spacing, enhancing the planter's adaptability and flexibility. This allows the planter to easily adjust the seeding row spacing to suit different planting needs, improving operational efficiency and planting results.

[0008] The adjustment base consists of a rear plate with curved, rearward-extending side panels at each end. A connecting beam is located between the two side panels. The square tubular connecting beam provides excellent structural strength while facilitating the installation and sliding of the slider. The adjustment base ensures stability and accuracy during movement.

[0009] A guide rod is fixed between the two side panels, parallel to the lead screw and mounted on a connecting beam. The connecting beam and the guide rod slide together, further enhancing the guidance and stability of the slider's movement. This prevents the slider from drifting or shaking during movement, ensuring accurate adjustment of the seeding row spacing.

[0010] Regarding the installation structure of the lead screw, the lead screw is rotatably installed on the two side plates, and the slider can be controlled to move precisely in the lateral direction by rotating the lead screw.

[0011] The lead screw passes through one of the side panels and protrudes outward, and the handwheel is installed at the end of the side panel where the lead screw protrudes. This allows the operator to easily turn the lead screw to control the movement of the slider, improving the convenience and efficiency of operation while also enhancing the user experience.

[0012] Regarding the components of the sowing device, the sowing device includes a seed box, a seed shovel and a suppression mechanism.

[0013] The short frame is shorter from front to back than the long frame, and the seeding devices on the short and long frames are staggered front to back. Because the seed boxes and suppression mechanisms occupy a larger lateral width, this staggered arrangement results in a more compact structure and shortens the seeding spacing. This allows the seeder to better cover the soil during operation, reducing missed seeds, improving seeding quality, and reducing seeding spacing, thereby increasing plant yields.

[0014] Regarding the structure of the long frame, a connecting beam is fixedly installed at the front end of the long frame, and a rear plate is fixedly installed at the front end of the connecting beam.

[0015] The rear plate is fixed to the frame by long bolts, ensuring that the long frame will not loosen or fall off due to vibration or impact during the seeding operation, thereby ensuring the overall stability and safety of the seed drill.

[0016] To sum up, the beneficial effects of the present invention are: a short frame is installed at the rear of the frame, and the short frame is designed to be movable left and right. The sliding fit of the slider in the adjustment seat and the threaded transmission of the lead screw and the slider are utilized to achieve precise adjustment of the sowing row spacing, meeting the needs of wide and narrow row planting modes.

[0027] A soybean planter with wide and narrow rows is provided with a single assembly, comprising a long frame 6 mounted at the rear of the frame, a sowing device mounted at the rear of the long frame 6, and the structural features of the same are as follows: a short frame 1 is mounted at the rear of the frame, the short frame 1 is located on the side of the long frame 6, a slider 4 is mounted at the front end of the short frame 1, an adjustment seat 3 is fixedly mounted at the rear of the frame, the slider 4 is slidably mounted in the adjustment seat 3 and can move left and right, a screw 5 is rotatably mounted on the adjustment seat 3, the screw 5 passes through the slider 4 and is threadedly engaged with the slider 4, and a handwheel 7 for rotating the screw 5 is mounted on the screw 5. Figure 1 A short frame 1 is installed at the rear of the vehicle frame and is designed to be movable left and right. The sliding fit of the slider 4 in the adjustment seat 3 and the threaded transmission of the lead screw 5 and the slider 4 enable precise adjustment of the sowing row spacing. This allows for flexible adjustment of the sowing row spacing, meeting the needs of wide and narrow row planting patterns.

[0028] Refer to the attached Figure 2 The front end of the short frame 1 is fixedly mounted with a connecting beam 2. The connecting beam 2 is in the shape of a square tube and extends vertically. The slider 4 is installed in the connecting beam 2. By moving the slider 4 left and right in the adjustment seat 3, the sowing row spacing can be flexibly adjusted, thereby improving the adaptability and flexibility of the seeder. This allows the seeder to easily adjust the sowing row spacing according to different planting needs, thereby improving operating efficiency and planting results. The adjustment seat 3 includes a rear plate 11, and the left and right ends of the rear plate 11 are provided with side plates 12 that are bent and extend backward. The connecting beam 2 is located between the two side plates 12. The square tube-shaped connecting beam 2 provides good structural strength and facilitates the installation and sliding of the slider 4. The adjustment seat 3 ensures the stability and accuracy of the slider 4 during movement. A guide rod 13 is fixedly mounted between the two side plates 12. The guide rod 13 is parallel to the screw 5 and is inserted into the connecting beam 2. The connecting beam 2 and the guide rod 13 slide in cooperation. This further enhances the guidance and stability of the movement of the slider 4. This prevents the slider 4 from deflecting or shaking during movement, thereby ensuring the accuracy of sowing row spacing adjustment.

[0029] Refer to the attached Figure 2 , Attachment Figure 3 Regarding the mounting structure of the lead screw 5, it is rotatably mounted on the two side panels 12. Rotating the lead screw 5 precisely controls the lateral movement of the slider 4. The lead screw 5 passes through one of the side panels 12 and protrudes outward. The handwheel 7 is mounted on the end of the lead screw 5 protruding from the side panel 12. This allows the operator to easily rotate the lead screw 5 to control the movement of the slider 4, improving operational convenience and efficiency while also enhancing the user experience.

[0030] Refer to the attached Figure 2 , Attachment Figure 4Regarding the components of the sowing device, the sowing device includes a seed box 8, a seed shovel 10, and a suppression mechanism 9. The short frame 1 is shorter than the long frame 6 in front-to-back length, and the sowing devices on the short frame 1 and the long frame 6 are staggered in front and back. Due to the large lateral width occupied by the seed box 8 and the suppression mechanism 9, the staggered arrangement can make the structure more compact and reduce the sowing spacing. This allows the seeder to better cover the soil during operation, reduce missed sowing, improve sowing quality, reduce the sowing spacing, and increase the planting yield.

[0031] Refer to the attached Figure 1 Regarding the structure of the long frame 6, a connecting beam 2 is fixedly mounted at the front end of the long frame 6, and a rear plate 11 is fixedly mounted at the front end of the connecting beam 2. The rear plate 11 is fixedly connected to the frame by long bolts 14, ensuring that the long frame 6 will not loosen or fall off due to vibration or impact during the sowing operation, ensuring the overall stability and safety of the seeder.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention.
