Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a manure spreader, specifically a manure spreader suitable for spreading compost such as cow manure, slurry compost, pig manure, berg compost, etc. .

(Prior art) As a manu-spreader, the applicant has already
``Manyure Spretsuda'' was proposed in Japanese Patent Application Laid-Open No. 58-216608. Furthermore, another known example is “Zeta
System Matsuku Sprayder (ZETOR
SYSTEM MUCK SPREADER)” (November 1978)
A horizontal beater-type manure spretzer and a vertical beater-type manure spretzer are known, such as those described in Agricultural Mechanization Research Institute Product Information Room, April 17, 2013, accession number 05131).

The horizontal beater type manu-spreader described above consists of a loading frame, a floor conveyor installed in the loading frame, and a crushing beater installed above the rear of the floor conveyor so that its shaft is parallel to the surface of the floor conveyor. It consists of rotating blades installed at the lower rear of the floor conveyor and a guide plate installed at the rear of the upper part of the crushing beater.

(Problem to be Solved by the Invention) However, for example, in a horizontal beater type manual spreader, when spreading compost mainly mixed with straw such as wheat straw or rice straw, the spreading width becomes narrow and the spreading becomes uneven. There were issues that arose. Possible reasons for this are as follows. In other words, compost is transported by a floor conveyor, but if you try to spread this type of compost by simply rotating the blades, the compost will hit the blades at the right time and be blown away by the blades, and the compost will drop directly onto the ground through the gaps between the blades. Compost is formed, causing uneven distribution, and the compost becomes entangled with the shaft, making the shaft look like a dumpling. If a flat landing is provided on the cargo frame side at the bottom of the blade, no compost will drip directly onto the ground. however,
Compost that does not hit the blades directly remains on the landing, where it is caught by the blades and thrown away. Therefore, after the compost has been discharged by the beater, it is better to move the compost in a series of continuous motions without stopping, which makes it possible to move the compost evenly and over a wide area. First, the compost must be stopped on top of the landing and then blown away again using a blade.
Compost movement lacks continuity and smoothness, making uniform distribution difficult.

Therefore, the applicant filed Japanese Patent Application Laid-Open No. 58-216608 (Patent Application No. 57
-101079), "A loading frame, a floor conveyor installed in the loading frame, and a shaft installed above the rear of the floor conveyor so that it is parallel to the surface of the floor conveyor, and the rotation direction of the shaft is parallel to the floor conveyor. A crushing beater whose direction of rotation is the same as the rotation direction of the drive shaft, a flat part which is installed at the lower rear of the floor conveyor so that its surface takes a horizontal direction and rotates, a blade which rotates together with the flat part, and a crushing beater. ``Manual aspretsuda characterized by comprising a guide plate provided at the rear of the upper part.'' However, if a protective plate or landing is provided near the flat part and the lower part of the blade, and compost, especially compost containing mainly straw such as wheat straw or rice straw, is spread, the flat part and Compost gets between the blades and the protective plate and adheres to the rotating shaft. If the adhesion is left unattended, the adhering compost will grow and become lump-like, making it impossible to spread it sufficiently.

(Means for Solving the Problems) The present invention includes a cargo frame, a floor conveyor installed in the cargo frame, a crushing beater installed at the rear of the floor conveyor and having a crushing blade surrounding it, and a crushing blade installed below the crushing beater. A flat part that is installed and rotates in the horizontal direction, a blade that is rotated together with the flat part, a protection plate provided close to the flat part and the lower part of the blade, and a protruding part from the flat part or the blade in the direction of the protection plate. To provide a manure spretzer, characterized in that it consists of a removal material provided in a straight line.

(Function) Even if compost tries to get in between the protection plate provided close to the flat part and the lower part of the blade, and the flat plate or blade, the protection plate provided protruding from the flat part or blade in the direction of the protection plate prevents compost from entering between the flat plate or the blade. The removal material is removed by rotating together with the plane part or the like.

(Embodiment) An explanation will be given according to FIG. 1 showing the right side of the embodiment of the present invention, FIG. 2 showing the power transmission plane, FIG. 3 showing a partially enlarged left side, and FIG. 4 showing the partially enlarged plane. . Reference numeral 1 denotes a cargo frame, which is composed of a front wall 2, side frames 3, and a bottom plate 4, and a floor conveyor 5 is hung on the bottom plate 4. Reference numeral 6 denotes an index culm, which is connected to a tractor hitch (not shown) and also serves as a part of the frame forming the bottom of the cargo frame 1. Reference numeral 11 denotes a crushing beater, and as shown in FIG. 3, a crushing blade 21 is detachably attached to the crushing blade 21 via six horizontal plates stretched in the longitudinal direction around a first shaft 15, which is the axis of the crushing beater 11. It becomes stuck. The crushing blade 21 is the crushing beater 11
It is formed in a spiral shape as a whole around the outer periphery of. The crushing beater 11 is formed to have a large diameter as shown in FIG. 4, and its lower end is close to the upper surface of the floor conveyor 5.
The rear end of the crushing beater 11 substantially coincides with the rear end of the floor conveyor 5.

That is, the second shaft 16 which is the drive shaft of the floor conveyor 5
In contrast, the first shaft 8 is arranged slightly forward. The first shaft 8 of the crushing beater 11 rotates in the same direction as the second shaft 16 which is the floor conveyor drive shaft of the floor conveyor 5, and is supported by a support frame 13 extending over the rear part of the side frame 3 in a rear view. The support frame 13 has an apron hanging down at the front and a guide plate main body 9 at the rear.

The guide plate main body 9 hangs down forward from the center of the disk 15 of the dispersion section at an appropriate distance outside the crushing beater 7, and an extending rubber member 28 is fixed to the lower end.
The guide plate main body 9 can be adjusted with an adjustment member. In this embodiment, a plate-shaped elastic body 28 is provided at the lower end of the guide plate main body 9.
Attach an extension rubber and extend it to a position lower than the first shaft 15. Reference numeral 13 denotes a transmission box, which is horizontally installed at a lower rear end of the floor conveyor 5. The transmission box 13 is the third
The shaft 17 passes through the shaft 17 and projects upward through appropriate gears, and in this embodiment has two vertical shafts capable of rotating at high speeds in mutually opposite directions.

Reference numeral 10 denotes a flat section, which in this embodiment is composed of disks, and two disks are fitted onto two vertical shafts, respectively. Three blades 18 are formed on the upper surface of the flat part 10, but the positions of the blades 18 do not matter as long as the compost can be placed on the flat part 10.
The tips of the blades 18 protrude to the outside of the periphery of the flat part 10, and the rotation loci of the tips of the blades 18 are as follows:
Each plane part 10 has an overlapping part a.
The formation positions of the respective blades 18 are such that their tips do not come into contact with each other even during rotation.

A protection plate 24 is provided at the lower part of the flat part 10 so as to coincide with the upper surface of the transmission box 13 before and after the upper surface of the transmission box 13. As is clear from FIG. 4, the rear end of the protection plate 24 has a circular arc shape that substantially matches the rotation locus of the tip of the blade 18, and protrudes slightly larger than the rotation locus. Reference numeral 23 denotes a guide upright plate, which surrounds the front along the rotation locus of the blade 18 and is connected to an auxiliary upright plate 26 that stands up from the cargo frame 1 on the side of the plane portion 10. The end of the auxiliary standing plate 26 wraps around in the direction of the flat part 10, and the tip has an acute angle.

Reference numeral 25 denotes an auxiliary blade made of a rubber material, and the protective plate 2
4 It hangs down to a position close to the top surface. Reference numeral 27 denotes a removal material, which is fixed to the back surface of the flat part 10 so as to be inclined in a direction to prevent compost or the like from getting caught up therein. In FIG. 2 showing power transmission, 12 is a human power shaft, which is driven by a tractor PTO shaft (not shown) through a universal joint, and drives left and right counter shafts 14, 14' through a distribution box 19. do. The counter shaft 14 includes a first shaft 15 for driving the crushing beater 11 and a third shaft 17 for rotating the flat section 10.
is driven via a transmission belt. Counter axis 1
4' rotates a second shaft 16 for driving the floor conveyor 5 via the transmission box 8.

Next, the operation of the embodiment will be explained. The compost transferred by the floor conveyor 5 is appropriately loosened by the crushing blades 21 of the crushing beater 7 installed close to the floor conveyor, and long straw etc. are cut and raked upward. The raked up compost collides with the guide plate main body 9, falls downward, and falls inside the upper surface of the flat part 10.

In this embodiment, the lower end of the plate-like elastic body 28 attached to the tip of the guide plate main body 9 is located at a lower level than the first shaft and extends almost to the lower end of the tip trajectory of the crushing blade 10, so that the compost can be mixed with a suitable compost. It becomes possible to concentrate the fall on the falling position. The loosened and cut pieces of compost that have fallen inside the upper surface of the flat part 10 are uniformly scattered outward by the blades 18 of the flat part 10 that rotate at high speed.

In this embodiment, since the rotation loci of the tips of the blades 18 installed on adjacent disks have a mutually overlapping portion a, the protrusions of the blades 18 reduce the amount of compost that comes into direct contact with the protection plate 24, causing it to fall. Since the fluidized compost inside is guided by the blades 18, the phenomenon of dropping of scum is prevented. Since the protection plate 24 is formed slightly larger toward the rear along the tip rotation locus of the blade 18, the blade 18 of the flat part 10 does not directly collide with an obstacle when moving or turning.
The blade 18 and the flat part 10 collide directly with the protection plate 24.
It also prevents compost from falling off. Exclusion material 27 provided on the back surface of the flat part 10
This makes it possible to prevent the entry of foreign substances and the like, and to eliminate the wrapping of the flat portion 10 around the vertical axis of rotation. Further, since the tip of the auxiliary standing plate 26 is made at an acute angle and extends somewhat inward, it is possible to prevent compost from adhering and accumulating at the end of the side frame. Since the second shaft, which is the floor conveyor drive shaft, is arranged slightly forward of the first shaft, the flat section 10 is not installed too far back.

(Effects of the Invention) Therefore, in this invention, even if compost gets in between the flat plate and the protective plate provided close to the flat part and the lower part of the blade, and the flat plate or the blade, it is removed and the compost does not get entangled around the rotating shaft. becomes less.
