The manure transported from the manure hopper and the conveying chassis is rotated and spread out through the rotation of the two swinging plates, which has the advantages of uniform spreading, etc.

[0004] However, in actual use, it still has the following defects: 1) The power integration design of the manure spreader is not reasonable enough, and a hydraulic motor needs to be configured before it can be used; 2) Manure is easily accumulated and squeezed in the silo, resulting in a large pressure on the conveying chassis, and the material is not easy to be transported out. Although a buffer grid composed of criss-cross cross bars and a total bar is designed, the effect is poor and the buffer grid affects the material falling; 3) The conveying chassis used for conveying manure is combined with the structure of the manure spreading board. Due to the complex materials in the manure, the conveying chassis is easily stuck, resulting in frequent problems with the material conveying structure, and the material conveying structure is very inconvenient to install on the silo.

[0038] The manure spreader mainly comprises a frame 4, a silo 1, a chain-type feeding mechanism, a spreading mechanism and the like.

[0039] The frame 4 is a frame-type structure as a whole, the silo 1 is located and installed on the upper part of the frame 4, and the bottom of the silo 1 is a funnel-type structure. The frame 4 is used as the main supporting structure to install the parts of the manure spreader. The front end of the frame 4 is provided with a connecting seat 11, and the manure spreader can be installed on a tractor through the connecting seat 11. The chain feeding mechanism is provided at the lower part of the silo 1 for conveying manure backward. During the use process, the manure spreader is always installed on the vehicle through the frame 4, and the manure in the silo 1 is conveyed backward to the spreading mechanism through the chain feeding mechanism, and then the manure is thrown through the spreading mechanism.

[0040] In this embodiment, a compact and highly integrated power structure is designed. Specifically, a longitudinal main transmission shaft 5 is arranged in the middle of the frame 4 at the lower part of the silo 1. The front end of the longitudinal main transmission shaft 5 is used to connect the power shaft of the vehicle and can rotate under the drive of the power shaft. The axial direction of the longitudinal main transmission shaft 5 is parallel to the conveying direction of the manure. A first reversing gearbox 8 is arranged on one side of the longitudinal main transmission shaft 5. The input shaft of the first reversing gearbox 8 and the longitudinal main transmission shaft 5 are connected by a pulley 6 and a belt 7 to realize power transmission.

[0041] In this embodiment, the chain feed mechanism mainly includes two transverse feed transmission shafts 10, one of which is used as a power component, on which a first sprocket 15 is installed, and a second sprocket 9 is installed on the output shaft of the first reversing gearbox 8. The first sprocket 15 and the second sprocket 9 are connected by a chain. In this way, the power of the longitudinal main transmission shaft 5 can be transmitted to the chain feed mechanism through the first reversing gearbox 8.

[0042] The material spreading mechanism is arranged at the rear part of the silo 1, and mainly includes two material spreading plates 19 and a second reversing gearbox 17. The second reversing gearbox 17 is arranged directly behind the longitudinal main transmission shaft 5, and its input shaft is connected to the end of the longitudinal main transmission shaft 5. There is a third reversing gearbox 18 on each side thereof. An output shaft is arranged on each side of the second reversing gearbox 17 and is connected to the corresponding third reversing gearbox 18. A material spreading plate 19 is connected to the upper part of each third reversing gearbox 18 for transmitting power to the two material spreading plates 19, so that the power of the longitudinal main transmission shaft 5 is transmitted to the material spreading mechanism.

[0043] In this embodiment, a transverse auger shaft 23 is provided in the silo 1, and two groups of stirring blades 24 are provided on the transverse auger shaft 23, and the two groups of stirring blades 24 rotate in opposite directions to ensure the stirring effect. The axis of the transverse auger shaft 23 is parallel to the axis of the transverse feed transmission shaft 10, and a third sprocket 2 is installed at one end of the transverse auger shaft 23, one end of one of the transverse feed transmission shafts 10 is extended outward and is installed with a fourth sprocket 3, and the third sprocket 2 and the fourth sprocket 3 are connected by a chain, so that power can be transmitted to the transverse auger shaft 23.

[0044] Through the above structure of this embodiment, after the longitudinal main transmission shaft 5 is connected to the power of the tractor, the power can be transmitted to the feeding structure, the spreading structure and the stirring structure, with high power integration and smooth and reliable operation.

[0045] In this embodiment, bearing supports are provided at both ends of the longitudinal main transmission shaft 5, the transverse material feeding transmission shaft 10, and the transverse auger shaft 23 to ensure flexible movement.

[0046] In this embodiment, a baffle 20 is provided at the discharge port at the rear of the silo 1 , and the baffle 20 can be raised and lowered by a hand wheel 21 , so as to adjust the size of the discharge port. Example 2

[0047] This embodiment provides a chain feeding mechanism with good performance, stable operation, not prone to jamming and easy installation.

[0048] The chain feeding mechanism mainly includes two transverse feeding transmission shafts 10, two annular conveying chains 13, several push rods 22, two support plates 12 and a bottom plate 14. The chain feeding mechanism is an independent part set, mainly supported by two support plates 12. The two support plates 12 are respectively arranged on both sides of the silo 1 and are installed on the side wall of the silo 1 and the frame 4 by screws. The two ends of the bottom plate 14 are fixed on the two support plates 12 to close the bottom of the silo 1, and the bottom plate 14 is located inside the annular conveying chain 13. The conveying chain 13 adopts a special structure, which is mainly a ring chain conveying chain formed by connecting several metal rings. Several push rods 22 are connected to the metal rings of the conveying chain 13 after flattening the two ends of a rectangular steel pipe. At the same time, a corresponding runner 16 is installed on the transverse feeding transmission shaft 10 to drive the conveying chain 13 to move. The chain feeding mechanism of this structure can be assembled as a whole by first assembling the parts, and then assembled into a whole part set and then installed on the silo 1. The special conveying structure has good stability and is not easy to get stuck. During use, the movement of the conveying chain 13 drives the pushing rod 22 to move, so that the manure can be pushed out of the silo 1. Example 3

[0049] This embodiment provides another material spreading mechanism. Specifically, a material spreading plate 19 can be set directly behind the silo 1. In this case, there is no need to set the third reversing gearbox 18. The material spreading plate 19 can be directly driven to rotate by the second reversing gearbox 17. This structure is suitable for use in scenarios where the silo 1 is smaller in size.
