Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide a crusher having a novel configuration suitable for crushing subsoil and fertilization substrate in pastures, etc.

The details of one embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a full-surface crusher of the present invention. The structure is such that a frame 3 has a front rod 3A, left and right rods 3B, and a rear rod 3C assembled in a rectangular plane and is configured to be towed by a tractor 2, and a drive shaft 4 is attached in a direction parallel to the front rod 3A of the frame. is rotatably attached to the front rod 3 in the frame 3.
An appropriate number of swinging rods 5 are connected to A so as to be swingable in parallel to the direction of movement of the frame, and an eccentric wheel 6 is provided on the drive shaft 4 for raising and lowering each swinging rod 5 alternately.
Each eccentric wheel 6 and each swinging rod 5 are connected by a link 7, and a vertical plate-shaped fork support plate 8 is attached to the swinging rod 5 so that it can rise and fall freely using a pin 8A as a fulcrum. A fork body 8B is suspended from the lower surface of the support plate 8 in a direction substantially perpendicular to the front rod 3A of the frame, and a return spring is provided between the advancing direction side of the support plate 8 and the tip of the swing rod. 9
A rubber stopper 10 is provided on the upper surface of the swinging rod to abut against the back surface of the upper end of the support plate 8. 3B and 3B' are three-point hitches for attachment to the tractor, 3C is the transmission, 3D is the transmission shaft, 3E is the gauge wheel that can be adjusted up and down,
3F indicates a transmission chain, and 9A indicates a protrusion protruding from the lower surface of the swinging rod 5. 11 is a safety device provided on the moving direction side of the swinging rod 5. Therefore, this device has a swinging rod 5' divided into front and rear parts,
A stopper 11B that comes into contact with the lower surface of the rear end of the front swinging rod 5' is provided on the tip surface of the rear swinging rod 5'', so that the front swinging rod 5'' A projecting piece 11C is provided on the rear upper surface of ',
This protruding piece and the rear swinging rod 5'' are connected to the spring 1.
Connected by 1D. According to this device 11, when the fork body hits an obstacle 12 as shown in FIG. 7, it bends around the pin 11A as a fulcrum (so-called escape).
Then, when the obstacle is removed, the spring 11D restores the original state. Further, the attachment states of the plurality of eccentric wheels 6 to the drive shaft 4 are set at different angles. 5A is a pin hole for connecting the swinging rod 5 and the link 7 with the pin 7A, 5B is a pin hole for connecting the support plate 8 and the swinging rod 5 with the pin 8A, and the pins 7A and 8A are connected as appropriate. By moving it, the height of the swinging rod and the insertion depth of the fork body can be adjusted.

Next, the operation of the present invention will be explained together with its effects.

When the drive shaft is operated in the state shown in FIG. 4, the eccentric wheel 6 rotates, and as a result, the fork body is stuck into the ground as shown in FIG. Since the entire fork is moved forward by the tractor in this state, the lower end of the fork body swings into the soil, crushing the subsoil and bedrock. After this, as the eccentric wheel rotates, the state as shown in FIG. 4 occurs. This is a useful invention that can greatly crush the subsoil, aid air circulation, and effectively improve land.
