Problems solved by technology

In the actual sowing process, due to the unevenness of the planting ground, the sowing device shakes a lot, which causes two problems. One is that the lifting distance of the seeds is long during the lifting process, and the seeds are easily shaken off from the seed picking spoon, causing leakage. broadcast
At present, in order to solve this problem, it is necessary to set up special personnel on many seeding devices to monitor the seed picking spoon. When the seeds on the seed picking spoon are found to be shaken behind, the seeds are replanted manually, resulting in high labor intensity and poor safety.
The second is that when the seeds fall in the sowing tube, due to the collision between the vibrating seeds in the sowing tube and the inner wall of the sowing tube, the falling time is prolonged and the sowing spacing is uneven. The maximum difference between the two is more than 80mm

Embodiment 1

[0020] Such as figure 1 , 2 , 4, 5, and 6 show that a kind of box 6 is installed on the frame 5, and a seed drop pipe 4 is installed on the lower end face. The road wheel 1 is fixedly installed at the end, and the main sprocket wheel 12 is installed on the road wheel fixed shaft.

[0021] A reduction box 10 is installed on the right side of the frame. In order to change the horizontal rotation into a vertical rotation, the reduction box adopts a bevel gear reducer or a worm gear reducer, and a sprocket 11 is installed on the input shaft in the reducer. The main sprocket and The sprockets are connected by a chain. An eccentric wheel 9 is installed on the output shaft in the reducer, the left end of the connecting rod 8 is hinged with the seed plate 3, and the right end of the connecting rod is hinged with the eccentric wheel, and the seed hole 7 is arranged on the seed plate.

[0022] On the frame of the seed pipe lower end, a fixed plate 13 is installed, and the seed pipe 1...

Embodiment 2

[0027] On the basis of Embodiment 1, the device is installed on a tractor, and the reduction box 10 is driven to rotate through the tractor's power output end and transmission chain, thereby realizing the cycle of taking seeds and sowing. That is to remove the fixed shaft of the road wheel, the main sprocket, and the road wheel, directly install the driving sprocket at the power output end of the tractor, and drive the eccentric wheel to rotate through the chain and the sprocket installed on the input shaft of the reduction box to realize the above-mentioned seed picking, Sowing cycle process.

Embodiment 3

[0029] On the basis of embodiment 1 or 2, change the device that drives the seed-taking plate to move left and right into oil cylinder or cylinder 16, utilize the high-pressure oil on the tractor or the piston rod in the gas cylinder to promote oil cylinder or cylinder to move left and right. In order to realize the above-mentioned working process of left and right movement, an electromagnetic control valve is installed on the pipeline connecting the tractor with the oil cylinder or the two inlets of the cylinder. The electromagnetic control valve is connected with the electrical control device, and the left and right movement speed of the piston rod is controlled by the electrical control device. Realize the left and right movement of the seed picking plate, and complete the cycle process of seed picking and sowing.

Abstract

The invention relates to agricultural machinery, particularly to a potato seeder. The device comprises a frame and a seed box mounted on the frame, and is characterized in that a seed falling pipe is mounted on the lower end face of the seed box, wherein a fixed plate is mounted on the frame at the lower end of the seed falling pipe; another seed falling pipe is mounted on the fixed plate; a seed fetching plate is mounted between the seed falling pipe and the fixed plate; seed fetching holes are formed in the seed fetching plate; a power device capable of driving the seed fetching plate to move left and right is mounted at one end of the seed fetching plate. According to the technical scheme disclosed by the invention, the potato seeder is novel in structure, convenient to fetch seeds, simple in structure, and low in production cost; the left and right reciprocating motion speed of the seed fetching plate can be changed conveniently, so as to adjust the row spacing.

Description

Technical field [0001] The present invention relates to an agricultural machine, especially a potato planter. Background technique [0002] At present, the seeding principle of the potato seeding device all adopts the seed scoop installed on the chain, after the potato seeds in the seed box are taken out by the seed scoop, after being lifted vertically to the highest point, it is thrown to the seed drop pipe for sowing. From the walking mode of the potato planting device, it is divided into two types: trailer type and self-propelled type. The trailer type is a way in which the potato planting device is pulled by a tractor. In this way, the seed picking chain in the seed picking device is driven to rotate by a sprocket wheel and a chain installed on the fixed shaft of the walking wheel. The self-propelled potato sowing device has its own power. Generally, the potato sowing device is directly installed on the tractor. The rotation of the seeding chain in the potato sowing dev...
