Description

An automatic compacting and retrieving device for silage

technical field

The utility model relates to an agricultural biomass silage device, in particular to an automatic compacting and retrieving device in silage feed storage equipment.

Background technique

Silage is the basic feed for ruminants in animal husbandry. Silage can well retain the nutritional quality of straw, forage or other agricultural biomass raw materials, and its nutritional value is higher than that of dry feed, and high-quality silage has good palatability, so it can ensure feed intake and digestibility. The principle of silage is to discharge the air in the silage raw material, make the facultative anaerobic lactic acid bacteria multiply and produce lactic acid, reduce the pH value of the raw material, make the storage system reach a stable state, and effectively preserve the feed.

The anaerobic environment required to manufacture silage is a key factor for storage success. In order to achieve anaerobic conditions, raw materials often need to be cut and crushed first. Taking corn stalks and commonly used forage as examples, the crushed particle size is generally 3 to 5 cm. Since the grass raw material is relatively soft and easy to compact, the particle size of cutting or crushing can be 5 to 10 cm. In the process of charging, the raw materials are subjected to repeated compaction treatment, and the air in the system is evacuated to the greatest extent.

The retrieving process is the most likely link to cause silage pollution. In the simple silage system, the feed port is also used as the discharge port. During the retrieving process, the part close to the discharge port will be in contact with the air. If the retrieving is improper or the opening time is too long, it will easily cause the reproduction of aerobic microorganisms. The silage is polluted and the quality of the feed is reduced.

In order to solve the problem of silage raw material compaction and reclaiming pollution, silage facilities have been developed to a certain extent, and various automatic devices with different functions have been introduced, such as feeding port crushing device, additive mixing device, pressing device and reclaiming excavation device etc. However, these automatic devices still have room for improvement. The feed cannot be effectively compacted after feeding, the accumulation of compacted feed is difficult for manual retrieving, and the anaerobic environment is seriously damaged after mechanical retrieving. Problems need to be further resolved. Based on the above deficiencies, it is necessary to design a silage working device with a simpler structure and more efficient use, to improve the degree of compaction of raw materials, storage sealing, and to ensure that the quality of silage during the retrieving process is not affected.

Contents of the invention

The purpose of this utility model is to improve the deficiencies in the prior art, provide a simple structure, easy to operate automatic silage compaction and retrieving device, improve the feeding efficiency and compaction degree of silage, and prevent the feed Deterioration due to exposure to air.

The technical scheme adopted in the utility model is as follows:

An automatic silage compaction and reclaiming device is composed of a feeding tower and a silage box, and the feeding tower is installed on the top of the silage box. The interior of the conveying tower is composed of a feed channeling device, a screw booster propulsion device, a material channeling device and a discharge pipe. There is a hydraulic lift at the bottom of the silage box, and a pressure sensor is set on the surface of the platform.

There is a circular feeding bin door at the center of the top of the conveying tower, and a bin cover is set outside the bin door, which can be sealed or opened by rotating the buckle lock. One end of the discharge pipe is provided with a circular retrieving bin door whose diameter is consistent with the outer diameter of the discharge pipe, and a bin cover is provided outside the bin door, which is sealed or opened by rotating the buckle lock.

The screw booster propulsion device is composed of a propeller motor and multiple sets of helical blades, which can rotate forward or reverse. The inside diameters match.

The feed guide device and the discharge guide device are bar-shaped devices with an isosceles triangle cross section, which are respectively located at the upper and lower parts of the screw booster propulsion device and are perpendicular to it, and fit with the largest screw blade at the corresponding position.

The pressure sensor on the hydraulic lift platform is connected to the pressure monitoring screen, and the platform of the hydraulic lift is attached to the inner wall of the side of the silage tank. When feeding and retrieving materials, the lifting speed and distance of the hydraulic lift are controlled according to the pressure data.

When feeding, the cover of the feed bin is open and the cover of the discharge bin is closed. The screw booster propulsion device rotates from the propeller motor to the opposite direction of the discharge bin door, and the raw material is diverted to the screw booster through the feed dredging device. The middle and rear parts of the propulsion device enter the silage box after being compressed. When the raw material is filled to a position higher than the feeding guide device, adjust the rotation direction of the screw booster propulsion device so that it rotates from the propeller motor to the direction of the discharge bin door, and at the same time Continue feeding, when the raw material reaches the door of the feeding bin, close and tighten the lid of the feeding bin, open the hydraulic elevator to compress the raw material, and close the screw booster propulsion device and hydraulic elevator after the raw material is compacted. The compactness of raw materials can be read through the data displayed on the pressure monitoring screen, and the lifting height can be adjusted according to the physical properties of the filled materials.

When retrieving material, the feed bin cover is closed and the retrieving bin cover is open. Start the screw booster propulsion device, and the propeller motor will rotate to the direction of the discharge bin door. At this time, the position of the hydraulic lift is lifted to push the silage upward. The silage material is introduced into the blades of the screw booster propulsion device from the discharge channeling device, and the material is continuously pushed into the discharge pipe and then pushed out of the retrieving bin door. After retrieving, turn off the propeller motor, close the retrieving bin cover and tighten it.
