Description

Technical Field

[0001] The utility model relates to the technical field of seed drills, in particular to wheat planting equipment with adjustable seeding spacing. Background Art

[0002] Wheat planting requires the use of a seeder. The sowing equipment of an existing seeder is usually connected to an independent wheel that rolls in contact with the soil. The rotation of the wheel drives the movement of a feeding structure on the seeder to achieve quantitative seeding. Alternatively, a linkage structure is set between the feeding structure and the wheel of the seeder, and the forward movement of the seeder drives the feeding structure to rotate to achieve quantitative seeding. However, the growth space required for wheat is different under different terrain and nutrient conditions. The existing equipment is not convenient for adjusting the sowing spacing, which is not conducive to the scientific growth of wheat.

[0003] To solve the above problems, we proposed a wheat planting equipment with adjustable sowing spacing. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 4 , a wheat planting equipment with adjustable sowing spacing comprises a storage barrel 1, the lower end of the storage barrel 1 is provided with an opening, the inner bottom wall of the storage barrel 1 is inclined, the storage barrel 1 is fixedly connected to the seeder, the storage barrel 1 is used to centrally store wheat seeds, the outer wall of the storage barrel 1 is fixedly connected with a guide shell 2 surrounding the lower end of the storage barrel 1, a feeding roller 3 that fits the opening of the lower end of the storage barrel 1 is movably inserted in the guide shell 2, and a feeding trough is provided on the outer wall of the feeding roller 3, the feeding trough can accommodate the volume of wheat seeds required for one sowing, and a discharge port 4 is provided on the lower side wall of the guide shell 2, a transmission shaft 5 is fixedly inserted in the middle of the feeding roller 3, and the left end of the transmission shaft 5 extends out of the outside of the storage barrel 1, when the transmission shaft 5 drives the feeding roller 3 to rotate one circle, the feeding trough obtains wheat seeds from the storage barrel 1 once and sends the wheat seeds out from the discharge port 4.

[0021] The left and right outer walls of the storage barrel 1 are symmetrically provided with a support rod 16 and a support rod 27 located in front of the support rod 16. The support rod 16 and the support rod 27 are fixedly connected with a guide groove 18 located at the lower side of the storage barrel 1. The guide groove 18 is tilted. A drop opening 9 is opened on the bottom wall of the guide groove 8. The drop opening 9 is located in front of the discharge port 4 in the horizontal direction, so that the wheat seeds fall onto the guide groove 18 and then fall out from the drop opening 9. The lower side wall of the guide groove 8 is symmetrically provided with a support seat 10 located at the rear side of the drop opening 9. The support seat 10 A baffle 11 corresponding to the blanking port 9 is rotatably provided on the upper side, a linkage shaft 12 is movably inserted at the lower end of the support rod 7, and a cam 13 located on the lower side of the baffle 11 is fixedly sleeved on the outer wall of the linkage shaft 12. The cam 13 is semi-cylindrical. When the convex surface of the cam 13 contacts the lower side wall of the baffle 11, the baffle 11 is lifted to close the blanking port 9. When the convex surface separates from the baffle 11, the baffle 11 immediately falls down to close the blanking port 9, and the baffle 11 is in a closed state half of the time for every rotation of the cam 13.

[0022] The left end fixed sleeve of the linkage shaft 12 is provided with a pulley 14, the left end fixed sleeve of the transmission shaft 5 is provided with a pulley 2 15 and a pulley 3 17, a belt 16 is sleeved between the pulley 2 15 and the pulley 1 14, the pulley 3 17 is connected to the motor for transmission, the outer side wall of the guide trough 1 8 is symmetrically provided with guide rails 18, the guide rails 18 are slidingly sleeved with a guide trough 2 19 located at the lower side of the guide trough 1 8, the lower side wall of the guide trough 2 19 is vertically inserted with a fastening bolt, the end of the fastening bolt is fixedly provided with a knob 20, the position of the guide trough 2 19 is adjusted to make the guide trough 2 19 extend forward.

[0023] The circumference ratio of the pulley 2 15 to the pulley 1 14 is 3:2. When the pulley 2 15 rotates two circles, the pulley 1 14 rotates three circles. Initially, the material trough is downward and the material drop port 9 is closed. When the pulley 2 15 drives the material roller 3 to rotate one circle, the material trough takes out wheat seeds from the storage barrel 1 once, and the wheat seeds fall onto the guide trough 1 8. At this time, since the pulley 2 15 rotates one circle, the pulley 1 14 will rotate one and a half circles. Under the rotation of the cam 13, the baffle 11 goes down, up, and down again, and the material drop port 9 opens, and the wheat seeds are discharged. The seeds fall from the feeding port 9 to the ground, completing a sowing operation. When the pulley 2 15 rotates one more circle to make the wheat seeds fall from the discharge port 4 to the guide trough 8, the pulley 14 rotates one and a half circles again, and the cam 13 also rotates one and a half circles, causing the baffle 11 to rise, fall, and then rise again. The feeding port 9 is closed, and the wheat seeds fall from the guide trough 1 8 to the guide trough 2 19, and then fall to the ground from the end of the guide trough 2 19, completing a sowing operation. The cycle continues in sequence, causing the wheat seeds to fall alternately between the feeding port 9 and the guide trough 2 19.

[0024] Reference Figure 5 , a represents the sowing spacing after the wheat seeds alternately fall out between the drop port 9 and the guide trough 19, b represents the sowing spacing after the wheat seeds fall out of the drop port 9 twice. When the driving speed of the seeder and the motor speed remain unchanged, the distance b remains constant, and the sowing spacing needs to be kept relatively uniform, that is, Figure 5 In the schematic diagram on the upper middle side, b is equal to twice a, or in the schematic diagram on the lower side, a is equal to twice b. By moving the guide trough 19 and adjusting the distance between the end of the guide trough 19 and the blanking port 9, b can be equal to twice a or a can be equal to twice b.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
