Description

Technical Field

[0001] This invention relates to the field of planting equipment technology, specifically to a wheat seeder with adjustable depth. Background Technology

[0002] Wheat is one of the three major grains. With the advancement of technology, existing wheat cultivation uses mechanical sowing to improve sowing efficiency. However, due to different soil environments, different sowing depths are required. In the process of using existing sowing equipment, the height of the sowing tray and the plow blade are fixed and cannot be adjusted, resulting in a low germination rate after wheat sowing and affecting wheat yield. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a wheat seeder with a simple structure, reasonable design, and convenient use that can adjust the sowing depth according to different soil conditions, thereby improving wheat germination and thus increasing wheat planting efficiency.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it includes a bracket, traveling wheels, a furrow cutter, and a cover plate. A material box is provided on the upper side of the bracket, and traveling wheels are arranged opposite each other on the lower side of the bracket. A furrow cutter is provided between the two traveling wheels. A discharge rack is provided on the left side of the furrow cutter. The discharge rack is connected to the material box, and a cover plate is provided on the left side of the discharge rack.

[0005] It also includes:

[0006] The fixing blocks are two in number, fixed to the bottom of the bracket in a front-to-back manner, and the furrow cutter is disposed between the two fixing blocks.

[0007] A connecting frame is provided between two fixed blocks and is located on the upper side of the furrow cutter. A support shaft is inserted and fixed inside the connecting frame, and the front and rear ends of the support shaft are respectively screwed into the corresponding fixed blocks by bearings.

[0008] A guide frame, wherein the guide frame is inserted into the bottom end of the discharge frame;

[0009] A drive assembly is disposed between the discharge rack and the connecting rack;

[0010] Through the above technical solution design, the drive component changes the cutting angle of the furrow blade, thereby changing its cutting depth. At the same time as the furrow blade changes, the drive component synchronously drives the guide frame, so that the guide frame can be adjusted in coordination with the furrow blade to protect the wheat seeds being discharged.

[0011] As a further improvement of the present invention, the driving component includes:

[0012] The drive motor is fixed to the right side wall of the feed rack and is connected to an external power source.

[0019] With the above technical solution design, the drive motor starts, and through the cooperation of the bevel gear assembly, the transverse threaded rod and the longitudinal threaded rod rotate synchronously. When the transverse threaded rod rotates, it drives the drive block to move through the thread drive, and through the sliding cooperation of the guide shaft, it causes the connecting frame to rotate around the screw joint of the support shaft, thus rotating the furrow blade. When the longitudinal threaded rod rotates, it drives the drive tube to move the guide frame through the thread, thus guiding the seeds.

[0020] As a further improvement of the present invention, the bevel gear assembly is composed of a transverse bevel gear and a longitudinal bevel gear. The transverse bevel gear is sleeved and fixed on the output shaft of the drive motor, and the longitudinal bevel gear is sleeved and fixed on the upper end of the support shaft. The longitudinal bevel gear and the transverse bevel gear are meshed together.

The annular grooves are located on the outer side of the connecting sleeve, a lower limit frame is provided on the lower side of the annular groove, an upper limit frame is provided on the upper side of the annular groove, and the upper limit frame is in contact with the lower limit frame. The upper limit frame and the lower limit frame are both in contact with the outer side of the connecting sleeve, and the front and rear contact ends of the upper limit frame and the lower limit frame are connected by bolts.

[0026] The above technical solution is used to install, disassemble, and replace the furrow cutter.

[0027] With the above structure, the beneficial effects of the present invention are as follows:

[0028] 1. Only one driving element, namely the drive motor, is needed. The transverse threaded rod and the longitudinal threaded rod can be driven synchronously through the cooperation of the bevel gear assembly.
