Peanut planting requires seed selection, land preparation, hole digging, sowing, suppression, fertilization, film covering and weeding. When digging holes and sowing, reasonable density is required. Large peanuts are generally planted in 8,000-10,000 holes per mu, and small peanuts are generally planted in 10,000-12,000 holes per mu. It is appropriate to sow two to three seeds per hole. In the current technological development, sowing devices are often used for mechanical sowing of peanuts to improve sowing efficiency and sowing quality.

[0003] The existing peanut sowing device includes a sowing vehicle, a hole-opening mechanism is installed at the front end of the sowing vehicle, and the hole-opening mechanism opens sowing holes of suitable density in the soil. A pneumatic seed meter is installed at the end of the sowing vehicle, and the pneumatic seed meter intermittently discharges peanut seeds so that they fall into the sowing holes opened by the hole-opening mechanism.

[0004] According to the different sowing areas and the sizes of peanut seeds, the hole-opening mechanism and the pneumatic seed-metering device of the existing device need to appropriately change their respective working frequencies, and the hole-opening mechanism and the pneumatic seed-metering device are installed on the sowing vehicle front and back, which requires precise setting of the discharge frequency of the pneumatic seed-metering device to ensure that the peanut seeds fall accurately into the sowing holes opened on the hole-opening mechanism, which is not only time-consuming and labor-intensive, but also delays the sowing progress of the peanut seeds.

[0005] Therefore, in view of the above situation, it is urgent to develop a peanut sowing device to overcome the shortcomings in current practical applications. Summary of the invention

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] The reciprocating lifting mechanism drives the hole opener to reciprocate and lift, and the arc groove can drive the rotating member A to reciprocate by reciprocating and lifting with the hole opener and cooperating with the sliding member. The rotating member A drives the two sets of gears A to reciprocate at the same time, and the two sets of gears A drive their respective gears B to reciprocate. One set of gears B drives the blocking member A to reciprocate and lift through the first blocking mechanism, and the other set of gears B drives the blocking member B to reciprocate and rotate through the second blocking mechanism.

[0039] When the hole opener moves downward, the blocking piece A moves toward the bottom of the hole opener. At this time, the gap between the blocking piece A and the inner wall of the hole opener gradually decreases. The hole opener can open a sowing hole on the soil by cooperating with the blocking piece A. The blocking piece B can block the discharge pipe B by rotating and cooperating with the blocking piece C. During this process, the seed metering device transports the peanut seeds to the discharge pipe B through the discharge pipe A and the corrugated pipe and retains them in the discharge pipe B. The blocking piece B during the rotation process can gradually block the discharge port of the discharge pipe B. When the discharge pipe B can retain the peanut seeds, the seed metering device only needs to perform seeding within the stroke range of a single reciprocating rotation of the blocking piece B, thereby expanding the adjustment range of the seed metering device's seeding frequency and reducing the number of adjustments of the seed metering device.

[0040] When the hole opener moves upward, blocking piece A moves toward the inside of the hole opener and releases the blockage on the bottom of the hole opener. Blocking piece B can release the blockage on discharge pipe B by rotating, and the peanut seeds in discharge pipe B enter discharge pipe C and finally fall into the sowing hole from the gap between blocking piece A and the inner wall of the hole opener. The hole opener is located directly above the sowing hole, so that the device can accurately sow the peanut seeds and sow them accurately to the center of the sowing hole, avoiding the peanut seeds from being sown to the outside of the sowing hole, speeding up the sowing progress of the peanut seeds, and improving the sowing efficiency and sowing quality of the device.

The gear A931 is concentrically fixed at the upper and lower ends of the rotating member A91. The gear A931 is meshed with the gear B932 installed on the bracket 933. The two groups of the gears B932 are respectively connected to the first blocking mechanism 10 and the second blocking mechanism 11. The bracket 933 is symmetrically fixed on the outer wall of the discharge pipe C65 around the rotating member A91.
