[0002] In dairy farming, cows produce 30kg of feces and 14kg of urine every day, which causes the growth environment of the cowshed to deteriorate, the ammonia concentration to be high, and mosquitoes and flies to breed. High-quality bedding and litter can increase the rest time of cows in the bedding, which is conducive to rumination. Bedding is made of cow dung as raw material and is made through aerobic fermentation.

[0003] The current horizontal fermentation tank is a common bedding fermentation equipment, and its main structure includes a bracket, a tank body, a driving device and a guide assembly.

This wear not only reduces the performance of the guide wheel, but also requires regular inspection and replacement of worn guide wheels. Due to the design of the fixed structure, the disassembly and assembly process of the guide wheel is usually complicated and time-consuming. This inconvenience leads to low efficiency in replacement and repair of the guide wheel during assembly and subsequent inspection and maintenance, which increases maintenance costs and downtime.

The guide wheel 7 is configured as a wheel member with an annular groove on the outer side. The annular groove is designed to accommodate and limit the guide part 22, and the two guide wheels 7 are respectively supported on both sides of the guide part 22.

[0033] In some embodiments, the driving device 3 in the utility model includes a gear rack 31 fixed on the bracket 1, and a gear 32 is rotatably connected to the inner side of the gear rack 31, and the gear 32 is meshed with the gear ring portion 21, wherein a motor 33 connected to the gear 32 is also fixed on the side of the gear rack 31, that is, the gear 32 is driven to rotate by the motor 33 during operation, so as to drive the ring gear portion 21 to rotate, thereby completing the rotation drive of the tank body 2.

In this way, the support of the tank body 1 and the driving stability are ensured by supporting the two sides of the two gear racks 31.

[0035] In addition, the lifting assembly 4 in the embodiment of the utility model includes a plurality of threaded columns 41 fixed on the bracket 1, and wing plates 51 are fixed on both sides of the bracket 5, and the wing plates 51 are penetrated by the threaded columns 41, wherein two nuts 42 are threadedly connected to the threaded columns 41, and the two nuts 42 are respectively clamped on both sides of the wing plates 51.

[0037] In this embodiment, two nuts 42 are used to adjust up and down to drive the entire bracket 5 to move up and down. During assembly, the entire bracket 5 can be adjusted to a horizontal position so that the guide wheels 7 on both sides can contact and support the guide part 22, thereby improving the convenience of assembly. Of course, after the guide wheel 7 is severely worn, the bracket 5 can be moved down to separate the guide wheel 7 from the guide part 22. Thereafter, the guide wheel 7 can be taken out and replaced for maintenance by opening the snap-fit ​​assembly 6, which greatly improves the convenience of subsequent use and maintenance.

After the rotating rod 64 is threadedly connected and fixed with the threaded tube 63, the fixing of the rotating seat 62 can be completed;

[0041] During maintenance and disassembly, the guide wheel 7 can be disassembled by reversing the above steps to improve the convenience of operation.

[0042] Furthermore, considering the need to stop and limit the two side edges of the guide portion 22 , the utility model further includes a stopper wheel assembly 8 disposed on the bracket 5 , and the stopper wheel assembly 8 is used to stop and limit the two side edges of the guide portion 22 .
