[0002] Large-scale mechanized poultry farms all face an important problem, that is, how to deal with poultry manure. According to statistics, a mechanized poultry farm that raises 300,000 poultry can discharge up to 30 tons of wet poultry manure every day. A large amount of wet poultry manure not only provides a breeding ground for the growth of pathogens and maggots, but also emits a foul odor, resulting in a decrease in the egg production rate of poultry. Traditional poultry manure is generally used as fertilizer, and its utilization rate is relatively low, resulting in little interest from poultry farm owners, so many poultry farms will have poultry manure accumulation. Poultry manure generally contains up to 80% of a large amount of water, so in the process of collecting poultry manure, the mixing and crushing components often stick to a large amount of wet manure.

The stirring and crushing rods 2 are of an arc-shaped structure, and one end of the stirring and crushing rod 2 connected to the middle rod 1 is provided with a detachable device, which plays the role of replacing, maintaining the stirring and crushing rod 2 and adjusting the stirring and crushing angle of the stirring and crushing rod 2 for poultry manure. In the utility model, the stirring and crushing rods 2 are two groups with the same curvature, and adopt an arc-shaped design, which effectively solves the problem of sticking manure compared with the old straight rod design; the arc-shaped stirring and crushing rod is an arc-shaped with R as the radius, and the center angle β is selected within the angle range of 0°<β<90°. After repeated use in actual production, when the center angle β is selected at an angle of 60°≤β≤80°, the effect of the arc-shaped stirring and crushing rod not sticking manure is more prominent.

[0028] like Figure 2As shown, in this embodiment, in order to improve the stirring effect of poultry manure and improve the crushing efficiency, a spring 3 is provided on the side of the stirring and crushing rod 2 close to the detachable device, and the spring 3 separates the stirring and crushing rod 2 into a stirring portion 23 and a connecting portion 24 with a detachable device, and the two ends of the spring 3 are respectively fixedly connected to the stirring portion 23 and the connecting portion 24. During operation, the middle rod 1 is driven to rotate by the transmission shaft, and since the connecting portion 24 of the stirring and crushing rod 2 is fixedly connected to the middle rod 1, the stirring and crushing rod 2 rotates accordingly. At this time, the spring 3 causes the arc-shaped stirring portion 23 to produce elastic swing under the action of the circumferential force, which plays a role in changing the stirring and crushing angle of the stirring portion 23 of the stirring and crushing rod 2, and at the same time produces a pumping effect on the wet manure, further improving the crushing efficiency.

[0029] In this embodiment, the connecting portion 24 provided with a detachable device is cylindrical, and the stirring portion 23 is an arc-shaped plate, with R as the radius, and the center angle β is selected within the angle range of greater than 0°<β<90° according to design requirements. After repeated use in actual production, when the center angle β is selected within the angle range of 60°≤β≤80°, the effect of the arc-shaped stirring and crushing rod not sticking to feces is more prominent. The stirring portions 23 of the two groups of stirring and crushing rods 2 are symmetrically arranged at the two ends of the middle rod 1 in opposite directions of the arc, and the two are connected by a connecting portion 24, so that the entire stirring and crushing rod device is S-shaped.

[0030] like Figure 3 , Figure 4 As shown, in this embodiment, the detachable device is a second thread 21 provided on the connecting portion 24 of the arc-shaped stirring and crushing rod 2, and the ends of both ends of the middle rod 1 are provided with connecting holes in the axial direction, and the side walls of the connecting holes are provided with first threads 11, and the connecting portion 24 is screwed into the connecting hole of the middle rod 1. The first thread 11 and the second thread 21 are screwed together so that the stirring and crushing rod 2 is fixedly connected to the middle rod 1. When the stirring and crushing rod 2 needs to be replaced or maintained, the first and second threads can be loosened to screw out the stirring and crushing rod 2.

[0031] Example 2

When pressure is applied to the elastic positioning ball 22, the elastic positioning ball 22 can be retracted into the outer surface of the connecting portion 24, and when the external pressure is eliminated, the elastic positioning ball 22 rebounds and protrudes from the outer surface of the connecting portion 24.

[0033] Positioning holes 12 are provided on the side walls of the connecting holes at both ends of the middle rod 1 , and the axes of the positioning holes 12 are perpendicular to the axes of the connecting holes at both ends of the middle rod 1 , so that the positioning holes 12 vertically pass through the connecting holes at both ends of the middle rod 1 .

[0034] In this embodiment, the positioning through hole 12 can be provided with one or more positioning through holes 12. The multiple positioning through holes 12 are evenly arranged on the side walls at both ends of the middle rod 1. The effect is best when 3-6 positioning through holes are arranged. The angle γ between the holes is set within the range of 0°-90°. When multiple positioning through holes 12 are provided, the connecting portion 24 can be clamped at different positions, so that the stirring and crushing angle of the arc-shaped stirring portion 23 can be adjusted.

[0035] The angle γ between the positioning through holes 12 on the side wall of the middle rod 1 is 15°, 30°, 45°, 60° or 90°. One elastic positioning ball 22 can be provided on the connecting portion 24, or two elastic positioning balls 22 can be provided at opposite positions.

[0036] When in use, the connecting part 24 is inserted into the connecting hole of the middle rod 1, and the elastic positioning ball 22 is engaged with the positioning through hole 12. When disassembly is required, the connecting part 24 is pulled out forcefully to separate the arc-shaped stirring and crushing rod 2 from the middle rod 1, or a pin is inserted into the positioning through hole 12 to push the elastic positioning ball 22 to retract it into the outer surface of the connecting part 24, and the connecting part 24 can be easily pulled out to separate the arc-shaped stirring and crushing rod 2 from the middle rod 1.

[0037] Due to the use of a detachable device in the utility model, the stirring and crushing rod device can replace different stirring parts 23 according to actual conditions, and the stirring and crushing angle of the stirring part 23 can be adjusted according to needs. At the same time, maintenance and cleaning are more convenient, which greatly improves production efficiency.

[0038] The preferred specific implementation modes and embodiments of the present invention are described in detail in conjunction with the accompanying drawings, but the present invention is not limited to the above implementation modes and embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the concept of the present invention.
