UA32270U - Mixer of fodders - Google Patents

Abstract

The utility model relates to the branch of agricultural machine building and can be used for mixing of materials, first of all - fodders.

Description

The utility model belongs to the field of agricultural engineering and can be used for mixing materials, primarily feed.

There are well-known portioned feed mixers (for example, VKO-1, 0-2, 0-7, C-12), which contain a hopper with a loading hatch, paddle mixers, an unloading auger and a neck (Revenko I.I., Shcherbak V.M.

Mechanization of animal husbandry. - K.; Higher education, 2004. - P.115-1171. These mixers do not provide high-quality mixing, as stagnant zones are created in the chute of the unloading auger and above it, into which a part of the feed that does not participate in mixing falls.

There is also a well-known feed mixer, which contains a case with a bottom in the form of troughs, in which blade agitators are placed, and an unloading auger is placed under them. A separating element in the form of a dihedral angle with curvilinear faces is installed under the agitators above the discharge auger, and the length of the edge of the angle is 0.6-0.7 of the length of the mixer body (a.s. USSR Me1822730, class A23M17/00, 1993).

This solution significantly reduces the size of the useful volume of the mixing chamber, in addition, stagnant zones are created near the side walls of the working chamber, which deteriorates the quality of mixing.

A useful model is the task of increasing the efficiency and quality indicators of the process of preparing fodder mixtures.

The task set by the utility model is achieved by the fact that in the feed mixer, which contains a hopper with an upper loading mouth, paddle agitators, a discharge auger and a mouth at the bottom of the hopper, according to the utility model, the discharge mouth is placed on the same side as the loading one, and the discharge auger is mounted in closed casing, which on the opposite side of the loading neck has an unloading window equipped with a latch.

Installing the unloading auger in a closed casing completely eliminates the possibility of removing unmixed components from the hopper. Placing the loading mouth and the unloading window on the auger casing at different ends of the hopper contributes to more intense (both in the cross-sectional area and in the longitudinal direction of the working chamber) mixing of the components and thus improves the quality of feed mixtures.

This is also facilitated by additional mixing with the unloading auger.

The feed mixer is schematically shown in Fig. 1, and its cross-section is shown in Fig. 2.

The feed mixer contains a hopper 1, in which paddle mixers 2 are mounted, and below them - an unloading auger 3. The hopper 1 is equipped with a loading 4 on top, and an unloading 5 on the bottom. Moreover, both mouths 4, 5 are located on one side of the hopper 1. The discharge auger C is installed in a closed casing b, which on the opposite side relative to the loading mouth 4 has a discharge window 7 equipped with a latch 8. The blades of the agitators 2 are arranged in a spiral pattern so as to ensure movement of feed in the process of their mixing from the loading neck 4 towards the unloading window 7 in the casing 6 of the auger 3.

Drives of the agitator, unloading auger and valve can be made according to known technical solutions.

A feed mixer works like this.

Pre-crushed fodder components are loaded through the receiving neck 4 into the hopper 1 with the valve 8 closed and mixed for 10-15 minutes with the help of paddle mixers 2. The loading level should not exceed 0.7-0.75 of the volume of the hopper 1.

In the case of simultaneous, uniform and continuous supply of initial components through the neck 4 into the hopper 1, the mixer can also work in flow mode. At the same time, the uniformity of the mixing of the components is regulated by the degree of opening of the latch 8 in the unloading window 7.

The finished fodder mixture is removed from the hopper 1 with the unloading auger C through the neck 5. For this, the drive of the auger C is turned on and the valve 8 is opened. During unloading, the fodder is additionally mixed with the auger 3.
