Description

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

[Prior Art] Soil for raising seedlings is obtained by crushing clods of soil collected from fields or fields to a specified particle size using a soil crusher or the like. Conventionally used as a crusher for lump soil.
The method shown in Publication No. 52-35590 is proposed, but since the angle of inclination of the cylinder mounted at an angle with respect to the machine frame remains unchanged, it is suitable for use with clods with low water content that move at a high speed. In the case of clods passing through the cylinder quickly, the crushed soil sorting efficiency is poor, and in the case of clods that move slowly and have a high water content, the clods adhere to the inner surface of the cylinder, impeding the crushed soil sorting efficiency. There is a problem with this.

In addition, conventional models have casters on all legs, so there is no problem in transporting and moving the machine, but especially in large crushers that handle a large amount of throughput, vibrations can cause the machine to move. However, there are problems such as the need for a mechanism to stop and maintain this.

[Purpose of the invention] The present invention was developed in view of the above-mentioned circumstances, and it solves the problems of the conventional technology by simple but rational means, and it is possible to change the shape of the cylinder according to the moisture content of the clod. It is an object of the present invention to provide an earth crusher that can adjust the inclination angle, efficiently crush and sort clods appropriately, and in addition, the machine body does not move due to vibration.

A base plate 14 is bridged between the one leg 1b, 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 this pulley 17 and a pulley 18 provided at the end of the rotating shaft 10 are connected by a belt 19, and a shaft is attached to one side frame 3b. A large diameter sprocket foil 21 provided on one end of the suspended shaft 20 and a small diameter sprocket foil 22 provided on the rotating shaft 10.
and is connected by a chain 23.

The above-mentioned roller 7 is loosely fitted to the other end of the shaft 20, and a gear 24 with a small diameter is provided at the other end of the shaft 20. The cylindrical body 5 is meshed with a gear 25 provided on the outer periphery of one side, so that the cylindrical body 5 rotates at a low speed and in the opposite direction to the rotary shaft 10 having the above-mentioned crushing rod 11.

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

26 is a hopper for supplying lump soil, which is attached to the above-mentioned side frame 3a.
The supply port is connected to the sloping upper end of the cylindrical body 5, and the sloping lower end of the cylindrical body 5 is used to discharge foreign matter such as solid soil, stones, grass roots, etc. that are larger than the specified granular soil. A guiding chute 27 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 planar mountain-shaped belt cover 28a 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, the side frames 3a, 3b
A shaft 29 is bridged between the tops of the safety covers 30, and the upper edges of the left and right safety covers 30 are hinge-supported on the shaft 29, and the lower edges of the safety covers 30 are fixed to the side frame 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 rod 33 for adjusting the inclination angle of the cylindrical body 5 is screwed onto one leg 1a.

[Function] To explain the next function, the machine body is transported to the work site with the leg 1a separated from the floor surface and only the caster 35 of the lever 34 in contact with the ground, and while the leg 1a is in contact with the ground, the lever 34 is Fold it down as shown in the figure, and secure the aircraft by touching the ground with the legs 1b. Next, when dry clods are put into the hopper 26, the clods are fed into the cylindrical body 5 which is rotating at a low speed, and are sequentially sent toward the discharge port along the slope of the cylindrical body 5. The soil is effectively crushed by the crushing rod 11 rotating at high speed in the opposite direction to the cylinder 5, and the crushed soil is sorted through the holes of the cylinder 5 and collected below the cylinder 5.

In addition, when the water content in the clod poured into the cylindrical body 5 is low, the screw rod 33 is operated to reduce the inclination angle of the cylindrical body 5 to lengthen the residence time of the clod, and to increase the moisture content of the clod. When there is a lot of movement, the inclination angle of the cylindrical body 5 is increased by operating the screw rod 33 to accelerate the movement. After the soil crushing work is completed, one leg 1b of the aircraft
Lift up the lever 34 and set the caster 3.
The aircraft is transported and stored with the other leg 1a separated from the floor.

[Effects] According to the configuration of the present invention as described above, the following effects can be obtained.

(a) The crushed soil introduced into the crushing chamber can be highly efficiently crushed, sorted and recovered; In addition to providing an adjustment mechanism, the upper end of the lever is pivoted to the lower end of the other leg so as to be able to stand upright, and a caster is attached to the lower end of this lever, and furthermore, a caster is attached to the lower end of this lever, and a caster is attached to the middle part of this lever so that when the lever is in the upright position, the side surface of the leg is Since a stopper is provided to lock the machine to the work site, it is easy to transport the machine by lifting one leg off the floor and grounding the caster of the lever connected to the other leg. Not only is this possible, but the machine frame, more specifically, the cylindrical body, can be automatically tilted at the work site by tilting the lever.

(c) Furthermore, when adjusting the inclination angle of the cylindrical body depending on the soil quality, minute adjustments can be made using the inclination angle adjustment mechanism of one of the legs. In other words, in the case of clods with low moisture content that move at a fast rate, the inclination angle of the cylinder is made small to lengthen the residence time in the cylinder, and in the case of clods with high moisture content that move at a slow rate, By increasing the angle of the cylindrical body, the progress is accelerated, soil is prevented from adhering to the inner wall of the cylindrical body, and the angle of the cylindrical body is adjusted according to the soil conditions, allowing for efficient soil crushing work. I can do it.
