Abstract

The present invention provides a fermentation device specially used for straw bio-feed, which belongs to the field of bio-feed processing equipment technology, and mainly covers key components such as side mixing troughs, middle mixing chambers, inner lifting cabin plates, and liquid spraying turntables. Specifically, the tail of the side mixing trough is interconnected and firmly connected with the upper part of the middle mixing chamber, and an inner lifting cabin plate that can slide along the vertical axis is provided in the inner middle part of the middle mixing chamber, and a rotatable liquid spraying turntable is installed above the middle mixing chamber. A central rotating shaft that can rotate in a circumferential direction is provided at the center of the inner lifting cabin plate, and an upper scraper is fixed to the lower outer side of the central rotating shaft in a circular array, and an outer scraper strip is also fixed to the upper outer side in a circular array, and an outer connecting frame is also fixed to the outer side of the inner lifting cabin plate. In actual operation, the side mixing troughs located on both sides of the middle mixing chamber play an important role in transporting the crushed straw and feed to the middle mixing chamber, so that the straw and feed can be transported to the middle mixing chamber simultaneously for mixing operations. This effectively solves the cumbersome process in the past where the rear straw must be moved under the feed before the feed can be put in, avoids the complicated operating procedures caused by the need for manual intermittent start-up, and greatly improves production efficiency.

Description

Technical Field

[0001] The invention relates to the technical field of biological feed processing equipment, and in particular to a straw biological feed fermentation equipment. Background Art

[0002] Straw bio-feed fermentation is actually the process of converting crop straw into bio-feed suitable for animal consumption with the help of microbial fermentation technology. In this process, the cellulose and lignin in the straw will be degraded, the protein content and digestibility will be improved, and the nutritional value and digestibility of the straw itself will be significantly improved. It also has many advantages such as low cost, easy operation, and long storage time. The fermentation process of straw bio-feed usually involves mixing the crushed straw, concentrate, and bacteria, and then sealing and packaging them to ferment in a sealed state.

[0003] In the actual material transportation and mixing process, two conveyor belts are generally used, which are responsible for transporting straw and feed to the same spiral conveyor trough, so as to achieve mixing operations while transporting. However, the two conveyor belts are arranged at intervals, so that there is a certain distance between the straw and feed they transport. When the equipment is just started, the straw and feed in this distance cannot be mixed immediately, or during the start-up phase of the conveyor belt, because it needs to be opened intermittently, it is easy for the straw on the rear side to move forward to the predetermined position before the feed is put in, resulting in the feed being piled directly on top of the straw. In this situation, it is necessary to rely on manual intermittent control, which undoubtedly adds additional operating procedures and processes and reduces overall production efficiency.

The middle connecting tension spring 403 pulls the head end of the movable frame 402 to slide and fit with the eccentric turntable 102. The eccentric turntable 102 drives the movable frame 402 to move back and forth horizontally. The movable frame 402 pulls the liquid spraying turntable 4 to reciprocate through the upper connecting pull rod 401.

[0034] A straw biological feed fermentation method: two side mixing troughs 1 on both sides of a middle mixing cabin 2 correspond to the conveyor belts of crushed straw and feed respectively, and the side mixing troughs 1 on both sides of the middle mixing cabin 2 convey the crushed straw and feed respectively, and the side driving motor 103 drives the inner spiral feeding teeth 101 and the eccentric turntable 102 to rotate, and the inner spiral feeding teeth 101 rotate while performing the horizontal axial conveying operation of the crushed straw or feed, and the straw and feed in the side mixing troughs 1 on both sides are simultaneously transported to the middle mixing cabin 2 for mixing, so as to avoid the straw and feed being in the same side mixing trough 1, and the conveyor belts of the straw and feed are arranged at intervals to convey the straw and feed to the side mixing troughs 1. The feed trough 1 and the side mixing trough 1 move horizontally to transport the straw and feed. When the straw and feed are mixed at the same time, the straw and feed are set at intervals.
