Description

Four row semi-automatic potato fertilizer planter

technical field

The utility model belongs to the technical field of potato sowing machinery, in particular to a four-row semi-automatic potato fertilizing planter.

Background technique

The planting area of potatoes in China accounts for 1/4 of the world's planting area, and the output accounts for about 1/5 of the world's output. It is China's fourth largest grain and vegetable crop. After establishing the status of potato as a staple food, the planting area of potato in China will be further expanded. But at present, the mechanization level of potato planting is low, and potato planting in some areas is still dominated by manual sowing. The labor intensity of farmers is high, and the operation efficiency is low. Can not meet the agronomic requirements of potato cultivation. And the existing potato planters generally have problems such as high reseeding rate, high missed sowing rate, and low qualified rate of sowing plant distance. It can be seen that the existing potato planters cannot fully meet the requirements of our country for potato planting.

Utility model content

The purpose of this utility model is to provide a potato fertilization planter with high operation efficiency, good operation quality and large fertilizer discharge capacity in view of the above-mentioned problems.

In order to achieve the above object, the utility model adopts the following technical scheme: the four-row semi-automatic potato fertilizing planter of the utility model comprises a frame and a left marking device installed on the frame, a right marking device, a transmission system, Fertilizer box assembly, seeding unit, long soil cover device, short soil cover device, suppressor and guard plate; fertilizer tank assembly is composed of fertilizer box, fertilizer box seat plate, spiral fertilizer discharger, transmission shaft tube and fertilizer retaining plate, installed At the front of the frame; the sowing unit is composed of a sowing frame, a fertilizing shovel installed on the sowing frame, a ditching shoe head, a sowing disc tray, a seeding disc, a baffle and a seed box, and is installed on the fertilizer box assembly At the rear of the machine, the fertilizing shovel corresponds to the fertilizer outlet of the spiral fertilizer device of the fertilizer box assembly; the ground wheel is used as a power source to provide the power required for the operation of the fertilizer box assembly and the seeding unit.

As a preferred solution of the present utility model, the sowing unit is composed of a sowing rack, a fertilizing shovel installed on the sowing rack, a ditching shoe head, a sowing disc pallet, a seeding disc, a baffle and a seed box. The fertilizing shovel and The ditching shoe heads are respectively installed under the seeding frame, the sowing disc pallet is fixedly mounted above the sowing frame, and two seeding discs are rotatably installed above the sowing disc pallet. Corresponding to the rectangular holes on the supporting plate, the two seeding discs are relatively arranged, and a baffle plate is inserted between each seeding disc and the sowing disc pallet, and the seed box is fixedly mounted on the top of the seeding disc.

As a preferred solution of the present utility model, the fertilizer box assembly is composed of a fertilizer box, a fertilizer box seat plate, a spiral fertilizer discharge device, a transmission shaft tube and a fertilizer retaining plate; the two fertilizer boxes are respectively fixed on the front of the frame On the left and right sides, one end of the seat plate of the fertilizer box is hinged on the fertilizer box, and two screw fertilizer devices are fixed under each fertilizer box. The screw fertilizer device is mainly composed of a sleeve and a screw, and the screw is rotatably installed on the sleeve. Inside, a fertilizer blocking plate is inserted between the fertilizer inlet and the fertilizer box above the spiral fertilizer discharger, and the fertilizer outlet below corresponds to the fertilization shovel, and the two spiral fertilizer dischargers are connected by a transmission shaft tube.

Due to the above-mentioned technical scheme, the four-row semi-automatic potato fertilizing planter provided by the utility model has the following beneficial effects compared with the prior art:

Since the potato fertilization planter arranges two seeding discs in each row, the two seeding discs can alternately cast seeds. When the planting distance is constant, the lower speed of the seeding discs can meet the requirements of the sowing operation. It is beneficial to improve the operation quality, the operation speed of the seeder and the operation efficiency; the fertilizer box assembly adopts the spiral fertilizer discharge device, which has a larger fertilizer discharge capacity than the commonly used outer groove wheel type fertilizer discharge device at present, and the fertilizer discharge capacity is as high as that of the two spirals. The spacing of the fertilizer discharger can be adjusted, which not only meets the requirements of potato planting on the amount of fertilizer, but also improves the adaptability of the machine tool to different sowing row spacing. The shape of the fertilizer box is designed as a seat, and the seat and the fertilizer box are combined into one First, it saves space and simplifies the structure. The seat plate of the fertilizer box can be opened to facilitate the cleaning of residual fertilizer. The operation quality, operation efficiency and fertilizer discharge capacity of the potato fertilizing planter are improved through the above method.
