Technical Field

The invention relates to a horizontal distributor for biogas manure, and belongs to the technical field of agricultural machinery.

Background

Experiments prove that the use of the biogas manure plays a remarkable role in crop growth and yield increase, not only can reduce environmental pollution to a certain extent, but also can maximally utilize rural waste resources, however, with the increasing amount of biogas in China, how to efficiently treat the biogas manure becomes a difficult problem to be treated urgently.

At present, biogas fertilizers produced in domestic biogas engineering are mainly used for realizing solid-liquid dual purposes through solid-liquid separation of biogas residues and biogas slurry, wherein the separated biogas residues are usually treated as organic fertilizers and returned to fields; the biogas slurry is mainly used for irrigation by planting and raising in south China, but the biogas slurry has the defects of large number of scattered households and small scale in animal husbandry in China, so that certain limitation is brought to the use of the biogas slurry for irrigation; in the north, a biogas slurry spreading machine is adopted to directly transport biogas slurry to the field for spreading application, namely the biogas slurry in the tank body is sent to a distributor by combining environmental protection requirements, agricultural requirements and the like, and finally the biogas slurry is scattered by a hose which sends the biogas slurry to shallow trench earth.

The use of biogas slurry by irrigation is not only labor intensive, but also affects existing irrigation systems, and therefore mechanical distribution of biogas slurry has become a necessary trend, wherein the distributor is a core component of the biogas slurry distribution machine. However, in order to prevent the distributor from being blocked, the conventional biogas slurry spreading machine needs to perform solid-liquid separation on biogas manure in advance, otherwise, the distributor is blocked and is unevenly distributed in the biogas manure distribution process, and other problems are caused.

Detailed Description

Examples

The horizontal distributor for the biogas manure comprises a frame 1 and a cylindrical shell 6 which is installed on the frame 1 and horizontally arranged, wherein a manure inlet 5 which can be communicated with a manure storage tank body 2 is formed in the shell 6, a horizontally arranged transmission shaft 1 is installed at the center of the shell 6, end covers are arranged on the left side and the right side of the shell 6 and are in threaded connection with the shell 6, a plurality of biogas manure discharge holes are formed in the end covers, hoses 7 are arranged at the biogas manure discharge holes, and preferably, all the biogas manure discharge holes in the same end cover are located on a circumference which takes the intersection of the end cover and the central axis of the shell as the center of a circle.

As shown in fig. 1-4, a rotor 10 is fixedly connected to the transmission shaft 11, the rotor 10 extends along the length direction of the transmission shaft, a plurality of strip-shaped rotor blades 10-1 which are consistent with the length direction of the transmission shaft 11 are arranged on the rotor 10 along the circumferential direction of the rotor, cutting rings 8 (fixed through bolts and the like) are detachably mounted on the inner sides of the two ends of the shell 6, the cutting rings 8 are shaped as shown in fig. 5, through holes which are in one-to-one correspondence with biogas manure discharge ports are formed in the cutting rings 8, and end cutting knives 13 which are matched with the cutting rings 8 on the two ends of the shell 6 are respectively arranged at the two ends of. Preferably, the rotor 10 is detachably fixed to the transmission shaft 11, for example, by bolts or pins, and the end cutters 13 are detachably mounted at both ends of the rotor 10. When the cutting tool is used, the strip-shaped cutting blade 10-1, the end cutting knife 13 and the cutting ring 8 are easy to wear and lose efficacy, so that the detachable rotor and the detachable cutting ring are adopted, and convenience is brought to subsequent part replacement.
