Bunch-planting type synchronous sowing and fertilizing machine

Abstract

The present invention provides a bunch-planting synchronous sowing and fertilizing machine which solves the technical problems that an current sowing and fertilizing machine cannot synchronously apply a fertilizer according to sowing positions, is serious in fertilizer waste, is complex in structure and large in size. According to the technical scheme, the key point is that a sowing device and a fertilizing device are an integrated type sowing and fertilizing device as follows: a roller-shaped bunch-planting wheel is fixed on a main shaft, wherein left and right chambers are arranged in the bunch-planting wheel; the bunch-planting wheel is provided with a duckbill-shaped soil opener which communicates with the two chambers respectively; the two chambers are respectively provided with a seeding unit assembly and a fertilizing unit assembly; a seed guide slot plate is arranged in the seeding unit assembly; a fertilizer guide slot plate is arranged in the fertilizing unit assembly; the fertilizer guide slot plate is in the shape of a circular slot with a radial fertilizer guide partition plate; a seed tank communicates with the seeding unit assembly; and a fertilizer tank communicates with the fertilizing unit assembly. According to the bunch-planting synchronous sowing and fertilizing machine, the length of the entire machine is shortened, operational flexibility is increased, accurate bunch planting is performed by synchronously implementing seeding and fertilizing, seeding and fertilizing intervals are maintained consistent, the fertilizer waste is reduced, and a fertilizer utilization rate is ensured.

Description

technical field [0001] The invention relates to an agricultural mechanical device, in particular to a hole sowing synchronous sowing and fertilizing machine. Background technique [0002] At present, sowing and fertilizing machinery has been widely used in agricultural production. The key to measuring the performance of sowing and fertilizing machinery lies in the precise control of the amount of sowing, the control of the amount of fertilization, the complexity of the whole machine structure and the cost of construction, etc. For peanuts, corn and soybeans Seed grains that require a higher depth of sowing are usually sown by hole sowing. Existing hole sowing type seeding and fertilizing machines are as follows: the announcement number is CN103597936A, and the name is called "Fertilization Laying Belt Film Multifunctional Planter". Including the frame, seeding device, fertilizing device and film covering device, etc., the traditional row seeding fertilization is adopted, the...

Problems solved by technology

[0003] The purpose of the present invention is to provide a hole-sowing synchronous sowing and fertilizing machine, which solves the technical problems that the existing sowing and fertilizing machines cannot synchronously fertilize according to the position of the seed hole, serious waste of fertilizer, complex structure, large volume, and poor bearing capacity. Sowing and fertilization are carried out simultaneously, and fertilization is accurately close to the seed hole to save fertilizer. The structure is simple, compact, flexible and has a large carrying capacity.
