Abstract

The invention relates to agriculture and provides increased operational reliability when transporting manure of various consistencies. The device comprises a housing 1. In the housing 1 a rod with pivotally mounted scrapers is placed, making reciprocating movements. In front of the casing of the blower 5 is located the discharge valve 6. The actuator pusher 4 provides the operation of the discharge valve 6. On the output part of the housing 1 there is a U-shaped protective casing 10. The lift limiter of the check valve 12 is made in the form of a plate 13 with a pointed edge 14. At during the operation of the pusher 4 and the closed discharge valve 6, the manure with its pressure opens the non-return valve 12. When the non-return valve 12 interacts with the pointed edge 14 of the plate 13, the inclusion of the long stem bedding and fodder The cuts are cut and do not prevent the full opening of the check valve 12 and the unloading of manure. 3 il.

Description

The invention relates to agriculture, in particular, to devices for transporting manure from livestock buildings, and is an improvement of the known device for unloading manure by ed. St. No. 1435217.

The purpose of the invention is to increase the operational reliability when transporting manure of various consistency.

FIG. 1 shows a device for removing manure, a longitudinal section; in fig. 2 - the same, a device fragment with a check valve; in fig. 3 is a view A of FIG. 2

The manure unloading device has a housing 1 with a lid 2, above which a guide 3 of the pusher 4 is located. In the front part of the devices there is a casing of the blower 5 equipped with a pressure valve 6 connected to the pusher 4. In the case 1 there is a rod 7 with scrapers 8, during operation, reciprocating. The pusher 4 and the rod 7 are driven by the actuator 9.

The device is equipped with a U-shaped protective casing 10, which is mounted on the output part of the housing 1. The protective housing 10 is made covering the housing 1 from the bottom and from the sides.

At the end of the cover 2 of the housing 1 by means of a hinge 11 a check valve 12 is installed. The side walls and the bottom of the protective casing 10 surround the check valve 12 from three sides. On both sides of the protective casing 10, in the front part of it, there is a check valve lift-up stop - at 12, preventing it from tilting and restricting its upward movement.

Limiter lift check valve is made in the form of a plate 13 with a pointed edge 14.

The manure moves along channel 15, ending in manure storage 16.

The process of unloading manure is carried out as follows.

Manure from the cattle-breeding premises along the channel 15 is scraped by 8, mounted on the rod 7, fed to the casing of the supercharger 5. At the return of the pusher 4 the casing of the supercharger

moves backwards, with the valve 6 of the supercharger open. During the working stroke of the pusher 4, the discharge valve 6 is closed and moves the manure to the manure storage 16, while the check valve 12 opens under the influence of the pressure of the manure mass created by moving the pusher 4 with the discharge valve 6 closed. As a result, the check valve 12 raises the manure mass cuts over it, and cuts through the inclusions of long stem litter and fodder debris, preventing its full opening. During the return stroke of the pusher 4, the check valve 12 closes under its own weight and the pressure of the slurry in the manure store.

Since the zone of movement of the check valve is closed on three sides, from the sides and bottom, with a protective cover 10, liquid or semi-liquid manure back into the housing can flow only from the front, and as the check valve closes, the flow area decreases all the time. Thus, the presence of a protective casing 10 at the end of the casing with closing the check valve 12 on three sides limits the return of manure to the casing, which increases the efficiency of the device, since with the same number of pusher strokes, more manure is transferred to the storage outside the barn, especially when transporting liquid and semi-liquid manure. The presence of the pointed edges of the check valve lift limiter ensures the cutting of the long-stem fraction of the manure, preventing the check valve from jamming.
