Description

[Detailed explanation of the idea] The present invention relates to improvement of an earth crusher.

The soil used for raising seedlings is collected from fields or fields and is crushed to a specified particle size using a soil crusher. To provide a crusher that can smoothly load lump soil into a soil and crush it effectively.

To explain the details of the embodiment with reference to the drawings, legs 1a, lb
Side frames 3a and 3b are provided at the left and right ends of the pedestal 2, which is tiltedly supported by the pedestal 2, and a cylindrical body with a large number of holes 4 made of a material such as a wire mesh or a punch plate between the two sides 3at and 3b. 5 is mounted horizontally at an angle so as to be rotatable at low speed.

Reinforcement rings 6a and 6b are provided at both ends of this cylindrical body 5, and these parts are supported by at least three wheels 7 provided on the side frames 3a and 3b.

Further, as is clear from FIG. 1, the reinforcing ring 6a,
6b, one end of an arm 8 which is inclined in the direction of soil movement and provided radially around the center of the cylinder 5 is fixed, and a bearing is attached to the gathering point of the other end of each arm 8. 9, and between both bearing parts 9, both ends of a polygonal rotating shaft 10 as shown in FIG. The bearing part 9 at the end of the rotary shaft 10 on the soil input side is located inside the cylinder 5 so that the arm 8 does not get in the way when loading the clod.

In this embodiment, one end of the arm 8 is fixed to reinforcing rings 6a and 6b provided at both ends of the cylindrical body 5.
Since the same effect can be obtained even if one end of the arm 8 is fixed to the side frame of the pedestal 2, the mounting position of the one end of the arm 8 is not limited to that of the embodiment.

Furthermore, this rotary shaft 10 is provided with crushed earth bodies 11 which alternately delay the phase by 90 degrees at appropriate intervals and are made of a thin plate-like elastic body such as a plate spring material.

A polygonal hole that fits the cross-sectional shape of the rotating shaft 10 is provided in the center of the crushed earth body 11, and this hole is inserted into the rotating shaft 10.
0, the crushed earth body 11 is installed so that the plate surface of the crushed earth body 11 is orthogonal to the axial direction of the rotating shaft 10.

12 is a partition pipe between each crushed earth body 11, 13 is a rotating shaft 10
A tightening nut is used to tighten and fix each crushed earth body 11 and partition pipe 12 against each other.

A base plate 14 is bridged between the legs 1b on the inclined lower edge side of the pedestal 2, and a motor 15 is provided on the base plate 14.

A pulley 17 is attached to the end of the drive shaft 16 of the motor 15, and the pulley 17 and the pulley 18 provided at the end of the rotating shaft 10 are connected by a belt 19. A large-diameter sprocket wheel 21 provided at one end of a shaft 20 mounted on the frame 3b, and the rotating shaft 10
The small diameter sprocket wheel 22 installed on the chain 2
It is connected at 3.

The above-mentioned roller 7 is loosely fitted to the other end of the shaft 20, and a small diameter gear 2 is fitted to the other end of the shaft 20.
4, the gear 24 meshes with a gear 25 provided on the outer periphery of one side of the cylinder 5, and when the cylinder 5 rotates at a low speed,
Moreover, it is configured to rotate in the opposite direction to the rotating shaft 10 having the crushed earth body 11.

The gear 25 provided on the cylindrical body 5 includes the reinforcing ring 6b.
It may be formed separately or may be provided separately.

26 is a hopper for supplying buried soil, which is located on the sloped upper end side 3 of the pedestal 2.
a, its supply port is open and communicated with the slanted upper end of the cylinder 5, and the slanted lower end of the cylinder 5 includes:
A chute 27 for discharging and guiding foreign matter such as solid soil of a specified granularity or larger, stones, and grass roots is provided, and the chute 27 is provided at the lower part of the side frame 3b.

The belt 19 is inserted through a hole 28 provided in the chute 27, and a belt cover 28 having a chevron-shaped planar shape is provided on the chute so that foreign matter to be discharged does not come into contact with the belt 19.

Further, as shown in FIG. 2, a shaft 29 is bridged between the tops of the side frames 3a and 3b, and the upper edges of the left and right safety covers 30 are pivotally supported on the shaft 29 in a hinged manner. 30 is fixed to the side frames 3a, 3b with screws 31.

In the figure, reference numeral 32 denotes a cover detachably provided on the side frame 3b so as to cover the entire outer surface of the side frame 3b.

Further, as shown in FIG. 1, a screw punch 33 for adjusting the inclination angle of the cylinder 5 is screwed onto one leg 1a, and one end of a lever 34 is pivotally supported at the lower end of the other leg 1b. A caster 35 is attached to the end of the lever 34, and the lever 34
A stopper 36 is provided in the middle of the lever 3.
4 is raised and the stopper 36 is engaged with the leg 1b to ground the caster 35, and the other leg 1a is moved away from the floor to allow smooth movement of the entire caster.

In the figure, 37 is a stay for leg retention.

Next, to explain the operation, when dry buried soil is put into the hopper 26, the buried soil is supplied into the cylinder 5 which is rotating at a low speed, and is sequentially moved along the slope of the cylinder 5 toward the discharge port. The soil is crushed by the crushing body 11 rotating at high speed in the opposite direction to the cylinder 5, and the crushed soil is sorted through the hole 4 of the cylinder 5 and collected below the cylinder 5. be done.

Further, foreign substances such as stones and grass roots contained in the buried soil thrown into the cylinder 5 are discharged from the discharge section to the outside via the chute 27 without being sorted and collected from the hole. Since the crushed earth body is formed of a plate-like elastic body such as a plate spring, even if a solid object such as a stone is caught between the tip of the crushed earth body 11 and the inner surface of the cylindrical body 5, the crushed earth body 11
is bent as shown in FIG. 1, so that the crushed earth body 11 and the cylindrical body 5 are not damaged.

In addition, because the crushed earth body is thin and rotates at high speed, grass roots and the like are cut and do not wrap around the crushed earth body.

As described above, according to the present invention, the buried soil put into the soil crushing chamber is highly efficiently crushed, and not only the bed soil of specified granular soil can be sorted and collected, but especially with the present invention, The bearing that supports the end of the rotary shaft on the fill supply side is located inside the cylindrical body, and this bearing is attached to one end of the arm, so that the end of the rotary shaft is on the fill supply side. The arm that extends and does not obstruct the input and supply of buried soil, and the arm supporting the upper bearing portion can also be arranged so as not to obstruct the input and supply of buried soil.

Therefore, it is possible to improve the filling efficiency of filling soil by forming a large hole in the filling port, which enables effective crushing of buried soil, and further improves the crushing efficiency by shortening the rotating shaft and eliminating vibration of the shaft. It has great practical effects, such as being able to measure
