Adjustable discharging opening structure for charging box of multifunctional seed sowing and fertilizer throwing machine

Abstract

The invention discloses an adjustable discharging opening structure for a charging box of a multifunctional seed sowing and fertilizer throwing machine. The adjustable discharging opening structure comprises a box body, wherein weighing scales are distributed on the inner side surface of the box body from the opening part of the box body to the bottom part of the box body; corresponding kilogram numerical values are formed in the inner wall of the box body, and correspond to weighing scales; bisectrices are uniformly distributed among the weighing scales; the bottom of the box body is tapered; a plurality of discharging openings are formed in the bottom of the box body at intervals; limiting plates are arranged on the two sides of the discharging openings in the lower end surface of the box body; a moveable baffle is clamped between the limiting plates; adjusting holes matched with the discharging openings are formed in the baffle; one end of the baffle is fixed at the bottom end of the box body through a tension spring; the movement of the baffle is driven through a stay wire or a pull rod at the other end. According to the invention, the weight of the material can be directly estimated in material pouring, weighing is not needed in advance, time and labor are saved, the work efficiency is improved, through the adoption of manpower to drive the baffle to move, the opening and closing of the discharging openings and the discharging amount can be adjusted conveniently, and moreover the control is convenient.

Description

technical field [0001] The invention relates to the field of seeding and fertilizer throwing machine equipment, in particular to an adjustable outlet structure of a charging box of a multifunctional seeding and fertilizer throwing machine. Background technique [0002] With the development of science and technology, the mechanization of agriculture has been developed to a certain extent. In some areas, sowing and fertilization are all done through mechanization. In order to meet the needs of the market, it has become a basic , the fertilizing and seeding machine in the prior art includes a power walking device and a fertilizing and seeding device. In the fertilization or seeding process of small soil, it is impossible to directly judge the amount of material during the pouring process. If the material is too little, it will not be enough, and if it is too much, it needs to be filled out. Therefore, it needs to be weighed and estimated in advance, which is labor-intensive and...

Problems solved by technology

[0003] The purpose of the present invention is to make up for the deficiencies of the prior art, and to provide an adjustable outlet structure for the charging box of a multifunctional seeding and throwing fertilizer machine, which solves the problem that the existing charging box has a simple discharging structure and cannot be directly poured into the Judging the amount of materials in the process needs to be weighed and estimated in advance. The labor intensity is high, time-consuming and laborious, which affects work efficiency. At the same time, the closure of the discharge port and the discharge volume cannot be controlled at any time.
