[0017] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0018] In the related technology, air dryers are commonly used equipment for drying poultry manure. The common steel plate manure air dryers on the market have high production costs and insufficient market competitiveness. In addition, when laying materials, the existing air dryers feed intermittently at the feed point and the feed amount is not constant. Therefore, how to achieve the continuity of laying materials with the air dryer is a technical problem that needs to be urgently solved by technical personnel in this field.

[0019] The material laying mechanism of the existing air dryer mostly uses a power device to drive the feeding mechanism to swing left and right to achieve material laying. The material laid by this structure is wavy and has uneven thickness. Moreover, the thickness is usually adjusted by adjusting the speed of the conveyor belt, resulting in the inability to accurately control the thickness and large deviation.

[0020] The present embodiment provides a belt-type manure air-drying device for drying poultry manure, which can ensure uniform thickness during continuous laying.

[0021] See also Figure 1-Figure 9In this embodiment, a belt-type manure drying device includes a frame 10, a storage bin 20, a material leveling device 30 and a weighing device 40, wherein a plurality of layers of conveyor belts 11 are provided on the frame 10, and the running directions of the upper and lower adjacent layers of conveyor belts 11 are opposite, and the conveyor belts 11 are used to convey poultry manure; the storage bin 20, the material leveling device 30 and the weighing device 40 are all installed on the frame 10, specifically, the storage bin 20 and the material leveling device 30 are arranged above the conveyor belt 11 on the top layer of the frame 10, the storage bin 20 is used to store poultry manure, the storage bin 20 includes a height-adjustable discharge port 21 arranged along the width direction of the conveyor belt 11, and the poultry manure inside the storage bin 20 is directly stacked on the conveyor belt 11 below it, under the action of friction The poultry manure in the storage bin 20 is brought out from the discharge port 21 by the conveyor belt 11; the leveling device 30 is arranged adjacent to the storage bin 20, and the leveling device 30 includes a leveling roller 31 arranged along the width direction of the conveyor belt 11 and with adjustable height, the leveling roller 31 has two sections of spiral blades with opposite rotation directions, and the overall axial length of the leveling roller 31 is greater than the length of the discharge port 21. When the poultry manure passes under the leveling roller 31 driven by the conveyor belt 11, the rotation of the leveling roller 31 will drive the two spiral blades thereon to rotate synchronously, and the poultry manure can be spread toward both sides along the width direction of the conveyor belt 11, thereby reducing the thickness of the poultry manure flowing out of the storage bin 20, so as to increase the spreading area and uniformity of the manure, thereby improving the air drying efficiency.

[0022] By adopting the technical solution of this embodiment, the manure in the storage bin 20 flows out continuously from the discharge port 21 along the conveyor belt 11, and is evenly spread along the width direction by the leveling roller 31 during the conveying process, ensuring the uniformity of thickness during continuous spreading.

[0023] See also Figure 1-Figure 4 In this embodiment, the conveyor belt 11 is distributed in multiple layers on the frame 10 along the vertical direction, and a head component 12 and a tail component 13 are provided at both ends of the frame 10. In order to allow large pieces of material to be quickly and effectively air-dried, a crushing device 14 is also provided on the head component 12. The crushing device 14 is used to break up large pieces of material so that the moisture inside can be easily air-dried, which can improve the air-drying effect.

[0024] See also Figure 5-Figure 6The storage bin 20 is formed into a rectangular frame by two horizontal plates 25 and two vertical plates 26. The two horizontal plates 25 are fixed between the two opposite side guard plates of the frame 10. The two horizontal plates 25 are arranged along the width direction of the conveyor belt 11. The two vertical plates 26 are fixed between the two horizontal plates 25. The two vertical plates 26 are arranged along the running direction of the conveyor belt 11. There is a certain gap between the lower end of one of the horizontal plates 25 and the conveyor belt 11. The gap forms a discharge port 21. A baffle 22 is provided on the horizontal plate 25 at the discharge port 21. The baffle 22 is arranged along the width direction of the conveyor belt 11 and is arranged vertically with the conveyor belt 11. Two support rods 23 are fixedly connected to the top of the baffle 22, and the two support rods 23 are symmetrically arranged on the top of the baffle 22. The support rods 23 pass through the flange at the top of the cross plate 25, and positioning nuts 24 are screwed on the support rods 23. The positioning nuts 24 are arranged on the upper and lower sides of the aforementioned flange. The two positioning nuts 24 clamp the aforementioned flange to fix the position of the baffle 22. By adjusting the position of the positioning nuts 24 on the support rods 23, the installation height of the baffle 22 above the conveyor belt 11 can be changed, thereby changing the height of the discharge port 21, and then changing the thickness of the feces when it flows out of the storage unit 20.

[0025] See also Figure 5 , Figure 6 and Fig. 9 A weighing device 40 is arranged under the conveyor belt 11 below the storage bin 20, wherein the weighing device 40 is used to weigh the poultry manure in the storage bin 20 to obtain the initial weight entering the air-drying device, and the weighing device 40 includes a weighing module 41, a roller assembly 42 and a lap rod 43, wherein the weighing module 41 is installed on the frame 10, the weighing module 41 is a prior art, and can adopt, for example, a German HBMZ6FD1 / 100kg weighing sensor, the roller assembly 42 includes a plurality of rollers arranged in parallel, each roller abuts against the lower surface of the conveyor belt 11, the lap rod 43 is arranged on both sides of the roller assembly 42, and the end of the lap rod 43 is lapped on the weighing module 41, and the weight of the poultry manure in the storage bin 20 directly acts on the conveyor belt 11, is transmitted to the roller assembly 42 through the conveyor belt 11, and is then transmitted to the weighing module 41 through the lap rod 43.

[0026] See also Figure 7-Figure 8 The material leveling device 30 as a whole includes two parallel arranged material leveling rollers 31. The material leveling roller 31 includes a roller shaft and spiral blades fixed on the roller shaft. The spiral blades are distributed in a spiral shape along the axial direction of the roller shaft, and two sections of spiral blades with opposite rotation directions are provided on the roller shaft to ensure that the feces can be synchronously transported to both sides of the width direction of the conveyor belt.

[0027] In this embodiment, a slide rail 15 for placing a material scrambling device 30 is fixedly connected to the top of the frame 10. The material scrambling device 30 also includes a side plate 32 for installing a material scrambling roller 31. The side plate 32 can be slidably clamped between the two slide rails 15. A support plate 16 is also fixedly connected to the top of the frame 10. A support beam 33 is rotatably penetrated between the two support plates 16. The support beam 33 is parallel to the material scrambling roller 31 and is located above the material scrambling roller 31. The support beam 33 is hinged between the side plates 32 with a basket bolt 34 to support The rotation of the beam 33 can drive the side plate 32 to move up and down, thereby changing the distance between the material leveling roller 31 and the conveyor belt 11, that is, adjusting the paving thickness; a positioning plate 35 corresponding to the support plate 16 is also fixedly connected to the support beam 33, and a detachable positioning column 36 is passed through the positioning plate 35. The positioning column 36 is correspondingly plugged into the positioning hole on the support plate 16, thereby connecting the positioning plate 35 and the support plate 16 as a whole to limit the rotation of the support beam 33. In order to facilitate rotation, a handle 37 is also fixedly connected to one end of the support beam 33.

[0028] It should be noted that this embodiment ensures the continuity of material laying through the cooperation of the storage bin and the weighing unit; the initial weight entering the air-drying device is calculated by the weighing unit, which is convenient for data comparison and calculation with the material after later air-drying; the spiral spreading and leveling of the material on the leveling device can improve the uniformity of the thickness; the height adjustment of the leveling roller on the leveling device can solve the uniformity and adjustability of the material thickness; the crushing device crushes large pieces of material, which can make the manure more evenly dried.

[0029] It should be understood that, in this embodiment, the overall thickness of the manure when it flows out through the discharge port is first controlled by adjusting the height of the baffle plate, and then the manure is spread along the width direction of the conveyor belt by using the leveling roller. Since the length of the discharge port is smaller than the length of the leveling roller, that is, when the manure flows out from the discharge port, its length along the width direction of the conveyor belt is smaller than its length along the width direction of the conveyor belt after being spread by the leveling roller, the thickness of the manure is reduced, while ensuring the uniformity of the spreading.

[0030] During operation, the manure and sewage transported from the outside falls into the storage bin and is weighed by the weighing module. When the set weight is reached, the first conveyor belt will drive the manure and sewage to be transported, and after reaching the end, it will fall into the second conveyor belt. Similarly, the manure and sewage will circulate back and forth and fall into the third conveyor belt, the fourth conveyor belt, the fifth conveyor belt, and finally be discharged at the active end P point of the sixth conveyor belt.

[0031] The manure coming out of the storage bin is evenly spread on the first layer of conveyor belt by the spreading roller when passing through the spreading device. The thickness of the spread manure can be adjusted by pressing the handle to drive the spreading roller up and down.

[0032] It should be noted that the bottom conveyor belt is a residue conveyor belt, which is used to collect the residue falling from the upper conveyor belt and transport it to point P for discharge. In this embodiment, the residue conveyor belt is a non-porous conveyor belt, and the conveyor belts above the residue conveyor belt are all conveyor belts with holes, so as to allow wind to pass through the manure and improve the air drying efficiency.

[0033] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
