Abstract

The invention discloses a novel vertical all-in-one machine for dry and wet feed smashing and mixing. To prevent a feeding port from being jammed by wet feed (fermented feed) and a feeding stirring shaft from being locked, pre-stirring shaft components with support are designed for performing added feed pre-stirring, so that the dry and wet feed and additive can smoothly enter on side of a threaded stirring shaft through a feeding stirring shaft; the feed is vertically conveyed upwards by the threaded stirring shaft, is thrown out when conveyed to the end of the threaded stirring shaft, slides downwards along the inner wall of a cylinder and a cone part of a shell, flows to the bottom, and is lifted upwards and thrown by the vertical threaded stirring shaft again; and the circulation is repeated, and evenly mixed feed can be acquired. A set of the pre-stirring shaft components with support is arranged in a main feeding chute; a workbench with adjustable height and convenience in operation and a safe screen preventing a feeding woven bag from entering the pre-stirring shaft are added; and the application range of vertical mixing machines is expanded.

Description

A new vertical dry and wet feed grinding and mixing machine

technical field

The invention belongs to the field of feed processing machinery, and in particular relates to a novel vertical dry and wet feed crushing and mixing machine which can not only crush corn, but also uniformly mix dry feed, wet feed (fermented feed) and additives.

Background technique

With the rapid development of my country's animal husbandry and the continuous improvement of the scientific and technological level of the breeding industry, higher requirements are put forward for the feed. The raw materials of the original feed factory can no longer meet the different requirements of each household at the same time. In order to further improve the quality of breeding, farmers need to adjust the feed by themselves, so that the vertical mixer with small footprint and low manufacturing cost that can meet the requirements of farmers will quickly sell well in the market, but the existing ones used in the market Vertical mixers are limited to mixing dry feed. In order to further expand the use function of the existing vertical mixer, improve its mixing quality, and increase its function of mixing wet feed and fermented feed, we have developed and produced a new type of vertical dry and wet feed grinding and mixing machine, which realizes a It is suitable for crushing corn and stirring various feeds (especially fermented wet feeds) to achieve the purpose of increasing mixing uniformity, reducing feed costs, saving energy, reducing environmental pollution from waste materials, and improving economic benefits.

Contents of the invention

The purpose of the present invention is to provide a new type of vertical dry and wet feed crushing and mixing integrated machine which is simple and reasonable in structure, small in floor space, light in labor intensity, convenient in operation and maintenance, sturdy and durable, and suitable for users.

The technical solution to achieve the above invention is: a new vertical dry and wet feed grinding and mixing machine, including a geared motor, a spiral stirring shaft, a main frame, a mixed feed inner and outer cylinder, an auxiliary frame, a corn crushing mechanism, a main feeding It is composed of hopper, auxiliary feeding hopper, pre-stirring shaft assembly with support, feeding stirring shaft assembly and height-adjustable operating platform. The spiral stirring shaft is vertically arranged in the middle of the inner and outer cylinders of the mixed feed, the upper shaft head of the stirring shaft is installed on the top cover through a bearing with a seat, and is connected with the reduction motor through a belt, and the lower shaft head of the stirring shaft is passed through a bearing with a seat Installed on the bottom cover, it drives the feeding stirring shaft in the main and auxiliary feeding hoppers to rotate through the belt. The auxiliary frame is provided with a corn crushing mechanism driven by an asynchronous motor. The crushing mechanism includes a suction pipe, a hammer, and a screen, and the discharge port communicates with the outer cylinder of the mixed feed through the auxiliary feeding hopper. When the new vertical dry and wet feed crushing and mixing machine is working, the operator pours the measured dry and wet feed and additives into the main feeding hopper on one side through the height-adjustable workbench in turn, and the pre-stirring shaft Stir, and be brought into the bottom of the screw shaft auger through the feeding agitator shaft; at the same time, the corn on the other side enters the crushing chamber through the suction pipe, and the corn is gradually crushed under the impact of the high-speed rotating hammer and the friction of the sieve plate , and under the action of centrifugal force and airflow, it is discharged through the discharge port, enters the auxiliary feed hopper, and is brought into the bottom of the spiral stirring shaft by the feeding stirring shaft; the feed fed on both sides is vertically upward by the spiral stirring shaft It is transported, thrown out after reaching the end of the spiral stirring shaft, then slides down the inner wall of the shell cylinder and the cone, flows to the bottom, and is lifted upward by the vertical spiral stirring shaft again, so that after repeated cycles , to obtain evenly mixed feed. After stirring, open the discharge valve to discharge the mixture.

In order to prevent the wet feed (fermented feed) from easily blocking the feed inlet and causing the feed stirring shaft to be stuck, a pre-stirring shaft assembly with support is designed to pre-stir the pre-mixed feed, so that both dry and wet feed can pass through smoothly The feed agitator shaft finally enters the helical agitator shaft, so as to complete the uniform mixing of various dry and wet feeds and additives, and the pre-stirrer shaft assembly can be adjusted and replaced according to actual structural requirements.

The invention installs a height-adjustable workbench at the main feeding hopper which is convenient for operators to feed materials and a safety net to prevent the woven bag from entering the pre-stirring shaft by mistake, thereby expanding the application range of the vertical mixer.

The present invention optimizes the parameter design of the spiral stirring shaft, and conducts dynamic simulation of the assembly relationship between the spiral stirring shaft and the inner cylinder of the mixed feed, finds out the best matching size, thereby increasing the convective mixing and shearing of the mixed feed Mixing, so that its mixing uniformity is improved and the mixing time is reduced.

Beneficial effects of the present invention: the present invention has the advantages of reasonable structure, small floor space, labor and time saving, less dust, good sealing performance, simple adjustment and maintenance, strong and durable, and the like. This new type of vertical dry and wet feed grinding and mixing machine can realize a machine suitable for crushing corn and mixing various feeds (especially fermented wet feeds) and additives, so as to increase mixing uniformity, reduce feed costs, save energy, and reduce waste materials. Environmental pollution, the purpose of improving economic efficiency. It is especially suitable for rural farmers, small farms and small and medium-sized compound feed factories.
