Description

The invention relates to an electric machine, which performs the chopping of coarse feed, used in animal feed, of small size and which is intended, in particular, for individual agricultural households.

Several types of chopping machines are known, for cutting coarse feeds, such as corn stalks, but most of them have large dimensions and high energy consumption, and their use in individual farms is not profitable.

It is known, from US 3578049, a chopper for processing coarse feed such as the stems of crop plants, which have a feeding table and a chopper made of groups of cutting discs, fixed on common shafts for each group. The distance between two neighboring shafts is smaller than the sum of the radii of the cutting discs, which are mounted offset on the shaft from the disks on a neighboring shaft, thus cooperating with each other during operation.

It is also known, from CN document 2523501 Y, a multifunctional chopper, which performs chopping of coarse vegetable material, such as maize stalks, the chopper having, as a chopping member, a blade blade, mounted on a shaft driven by an electric motor. The machine has an upper guard and another lower guard, which also has the role of evacuating the chopped plant material, and the feeding, with the material to be processed, is made through a feeding mouth.

The technical problem, which the invention aims to solve, consists in the creation of a machine intended for the cutting of coarse feeds, used in animal feed, of small size, with low energy consumption and safe operation.

The invention provides an electric machine for chopping coarse fodder, consisting of a drum on which a drill is mounted, in which the chopping of the plant material takes place, and a feeding table, which takes the plant material and transfers it to the drill, where a knife acts. chopper, whose knife-bearing shaft is driven by an electric motor, mounted on the bat, the chopping knife being composed of three elements of different sizes, welded to each other, of which one element represents the cutting element, having a first radius and a first width, and the other two elements are reinforcing elements, which have radii and width smaller than those of the cutter element, being placed behind the cutter element by 1 cm, five pairs of wings are provided on the cutter element, which ensures a uniform cut and eliminating the risk of damage to the active parts of the machine during operation.

The electric coarse grinding machine according to the invention has the following advantages:

- it has small dimensions and low energy consumption, being indicated for individual agricultural households;

- the vegetable material is evenly chopped;

- it has a simple construction and presents safety in operation, which can be used by an operator after a minimum period of technical training;

- Reduces the costs of providing food for domestic animals.

The following is an example of an embodiment of the invention in connection with FIG. 1 ... 5, which represents:

FIG. 1, perspective view of the chopping machine;

FIG. 2, top view of the chopping machine;

FIG. 3, kinematic diagram of the chopping machine;

FIG. 4, view of the chopping knife;

FIG. 5, view of the feeding table.

The electric machine for coarse forage, according to the invention, has a battery 1, made of 60 x 60 mm iron, on which all the machine's subassemblies are mounted.

RO 126358 Β1

The dimensions of the machine are as follows: the length of the shelf a = 102 cm, the width of the shelf b = 1 cm, the height of the shelf c = 89 cm, the height of the support legs d = 30 cm, the dimensions of the chopping machine being e = 59 cm, f = 24 cm, g = 48 cm. The machine has a chopping knife 3

2, made of 3 mm thick sheet metal. The chopping knife 2 is composed of three elements x, y, z (fig. 4), welded together, the element y being the cutting element, having a width of 5 5 cm, while the elements x and z are reinforcing elements, having, each, 4 cm wide.

The reinforcing elements are placed behind the cutting element y, by 1 cm (fig. 4). R 7 is the radius of the circle from which the chopping knife is cut, R 1 = 20 cm, R 2 = 29 cm, R 3 = 39 cm.

Chopping knife 2 is provided with five pairs of wings 8, for removing chopped material 9 from the drill. The wings are welded by the knife, and their dimensions are: m = 2, 5 cm, n = 2,5 cm, o =

I, 8 cm (fig. 4). 11

The cutting of the plant material is made inside a drum 3, made of 2 mm thick sheet, of circular shape. The radius R 4, of the drum 3, is 42 cm, and the thickness 13 i, of the drum 3, is 20 cm (Figs. 2 and 3). The drum is fixed on one side by the battery 1 and the other side, which represents the door of the drum, is screwed. 15

The feed table 4 is made of iron plate 2 cm thick, and its dimensions are as follows: 56 cm long, 30 cm wide and 17 cm high. The other dimensions are: h = 25 cm, I = 7.5 cm, p = 4 cm, r = 34 cm, s = 2 cm, t =

II, 5 cm, u = 10 cm, v = 15 cm, k = 22 cm, r and t being interior dimensions (fig. 5). The table of 19 feeds 4 is provided with a feed roller 7, made of iron pipe with a diameter of 11 cm, the length is 32, 2 cm, and the corners are rounded (fig. 2). Advance roll 7 moves freely, as needed, up and down. Its action is gravitational, having the role of fixing the plant material to be processed in the feed table 4. The feed table 23 4 is fixed, by the rod 1 and by the drum 3, by means of screws.

The knife-bearing shaft 5 is widened with bearings and makes it possible to transform the electric machine 25 for chopping coarse fodder into a straightener.

To perform a processing of the plant material to the desired parameters, the electric motor 27 and the feed table 4 are adjustable. between the shredder knife 2 and the feed table

4, a spacer 9 is provided, made of plywood 1 cm thick. The spacer 9 is 29, fixed from the outside, by the feed table 4, with screws and can be changed as needed (fig. 5). The support 11 has a width of 6 cm (fig. 2). 31

The operation of the machine for coarse fodder takes place in the following way. The coarse vegetable material, to be processed, is inserted into the feed table 4 and is pushed to the cutting knife 2. The chopping is done inside the drum, and the chopped vegetable material is collected by gravity (fig. 3). 35
