When the conveying device needs to be used, the device is placed on the designated workstation through the supporting feet 86 provided at the four corners of the bottom surface of the bottom support seat 82. At this time, the external oil pump can be regulated, the telescopic cylinder 84 is operated, and the telescopic end of the telescopic cylinder 84 is extended and retracted, thereby driving the conveying frame 1 to change its angle with the center of the left rotating block 81 as the axis, thereby changing the direction of the right side of the conveying frame 1, and then changing the discharge direction of the discharge hopper 7;

[0026] Stable conveying mechanism 2: It includes a middle fixed frame 21, a large-angle U-shaped frame 22, a rear fixed plate 23, a front fixed plate 24, a middle roller 25, a side roller 26 and a driving roller 27. The middle fixed frame 21 is fixedly connected between the front and rear inner walls of the conveying frame 1. The upper and lower surfaces of the middle fixed frame 21 are provided with evenly distributed large-angle U-shaped frames 22. The rear side of the upper surface of the large-angle U-shaped frame 22 is provided with a rear fixed plate 23.

The front and rear inner walls of the conveyor frame 1 are symmetrically rotatably connected to the driving rollers 27. The two driving rollers 27 are connected by the conveyor belt 3. The outer arc surfaces of all the side rollers 26 and the driving rollers 27 are in contact with the inner surface of the conveyor belt 3. The control switch 6 is also included. The control switch 6 is set on the front side of the conveyor frame 1. The input end of the control switch 6 is electrically connected to the external power supply. The drive motor 5 is also included. The driving motor 5 is arranged on the left side of the front side of the conveying frame 1, and the output shaft of the driving motor 5 is fixedly connected to the front end of the driving roller 27 on the left side. The input end of the driving motor 5 is electrically connected to the output end of the control switch 6. The outer surface of the conveyor belt 3 is provided with evenly distributed isolation ridges. At this time, the control switch 6 is adjusted to drive the driving motor 5 to run, and the output shaft of the driving motor 5 rotates, thereby driving the driving roller 27 on the left side to rotate, and then rotating the driving roller 27 on the right side of the conveyor belt 3. At this time, the cow dung that is preliminarily processed can be put into the left side of the upper surface of the conveyor belt 3 through the feed hopper 4 through the external feeding equipment. At this time, the conveyor belt 3 is fed to the right. When delivering cow dung, when the cow dung is transported to the right, it leaves the conveyor belt 3 along the discharge hopper 7. When the conveyor belt 3 rotates, the trapezoidal scraper will scrape off the stubborn cow dung lumps to prevent them from affecting the subsequent conveying operations. During this period, when the inner surface of the conveyor belt 3 is always in contact with the middle roller 25 and the side rollers 26, after the conveying angle changes, when the conveyor belt 3 transports heavier cow dung, the pressure will be dispersed to the middle roller 25 and the side rollers 26 in real time to prevent the cow dung on the conveyor belt 3 from being too heavy, which will affect the transmission force of the driving roller 27. The multi-point conveying method can also effectively prevent the conveyor belt 3 from being stretched and broken due to excessive pressure.

[0027] The working principle of the cow dung fertilizer fermentation conveyor provided by the present invention is as follows: when the conveying device is needed, the device is placed on the designated work station through the support legs 86 provided at the four corners of the bottom surface of the bottom support seat 82. At this time, the external oil pump can be regulated to operate the telescopic cylinder 84, and the telescopic end of the telescopic cylinder 84 is extended and contracted, thereby driving the conveying frame 1 to change the angle with the center of the left rotating block 81 as the axis, thereby changing the direction of the right side of the conveying frame 1, and then changing the discharge direction of the discharge hopper 7. At this time, the control switch 6 is regulated to operate the drive motor 5, and the output shaft of the drive motor 5 is rotated, thereby driving the driving roller 27 on the left to rotate, and then rotating the driving roller 27 on the right side of the conveyor belt 3. At this time, the external feeding equipment can be used to The initially processed cow dung is put into the left side of the upper surface of the conveyor belt 3 through the feed hopper 4. At this time, the conveyor belt 3 transports the cow dung to the right. When the cow dung is transported to the right, it leaves the conveyor belt 3 along the discharge hopper 7. When the conveyor belt 3 rotates, the trapezoidal scraper will scrape off the stubborn cow dung lumps to prevent them from affecting the subsequent conveying operations. During this period, when the inner surface of the conveyor belt 3 is always in contact with the middle roller 25 and the side rollers 26, after the conveying angle changes, when the conveyor belt 3 transports cow dung of greater weight, the pressure will be dispersed to the middle roller 25 and the side rollers 26 in real time to prevent the cow dung on the conveyor belt 3 from being too heavy, which will affect the transmission force of the driving roller 27. The multi-point conveying method can also effectively prevent the conveyor belt 3 from being stretched and broken due to excessive pressure.

[0028] It is worth noting that the drive motor 5 and the telescopic cylinder 84 disclosed in the above embodiment can be freely configured according to the actual application scenario. It is recommended to use the AMV450-5500-11~30 large vertical gear reduction motor for the drive motor 5, and the telescopic cylinder 84 is recommended to use the 4TG-E150*830ZJ model hydraulic cylinder. The control switch 6 is provided with a control button corresponding to the drive motor 5 and used to control its switch.
