Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waste material cutting machine that cuts into pieces waste material generated from demolition of houses and the like.

A large amount of waste wood is generated when a house is demolished, and in the past, these waste materials were simply transported without being cut into small pieces. This was not only because there was no scrap wood cutting machine that could be easily transported to the house demolition site, but also because there was no cutting machine that could cut the waste wood into smaller pieces of appropriate size. It was necessary to take the method of transporting it without cutting it, which caused a large loss in loading.

The present invention was developed in view of these points, and its purpose is to simply throw the waste wood into the hopper, and the waste wood will be cut into small pieces of appropriate size, and will be free from nails and knots. The purpose of the present invention is to provide a waste material cutting machine capable of cutting with a cutting force corresponding to the thickness of the waste material without damaging the blade in the extremely hard parts. To provide a waste material cutting machine capable of efficiently discharging powder such as cutting waste.

The present invention will be described in detail below based on the illustrated embodiments. In the figure, 1 is a feed roll, 2 is a vertical cutting roll, and 3 is a horizontal cutting roll, each of which is provided in pairs, and is erected from a chassis 9. Both ends are connected to a support body 4 which is made of aluminum. The support body 4 is gate-shaped, and its lower ends on both sides are fixed to a chassis 9. The support body 4 at the first stage has a pair of feed rolls 1, 1, and the support body 4 at the next stage has a pair of vertical cutting rolls 2. , 2, and a pair of transverse cutting rolls 3, 3 are attached to the final stage support 4, respectively. These rolls 1, 2, and 3 arranged vertically by respective supports 4 are each lower roll 1,
2 and 3 are rotatably supported on a support 4, and all of the upper rolls 1, 2, and 3 are urged by springs 8 in the direction of the lower rolls 1, 2, and 3. These springs 8 are arranged in the side columns of the support body 4, and have their upper ends in contact with the adjustment bolts 15, and their lower ends in contact with the movable bearings 16 of the respective upper rolls 1, 2, and 3, which are movable up and down within the side columns. By adjusting the amount of compression of the spring 8 using the adjustment bolt 15, the spring biasing force is made variable. The feed roll 1 has many small protrusions 1 on its circumferential surface.
1, and is formed, for example, as a rubber roller, and a hydraulic motor 20 is connected to the shaft of the lower feed roll 1. As shown in FIG. 5, the tension of the upper feed roll 1 and the lower feed roll 1 is adjusted by a tension sprocket 18 between sprockets 17, 17 provided at one end of the shaft of each roll 1, 1. They are connected by a chain 19. The vertical cutting roll 2 is formed by attaching a large number of rotary blades 12 to a shaft as shown in FIG. 12 through a small gap. 21 is a reinforcing bearing part. Although this vertical cutting roll 2 is not provided with a power source and is simply configured to be able to rotate freely, it goes without saying that a power source such as a hydraulic motor may be connected to this vertical cutting roll 2 as well. The transverse cutting roll 3 has a rib-shaped blade 1 along its circumferential surface in the axial direction.
3 are arranged in a row, the lower transverse cutting roll 3 is connected to a hydraulic motor 20, and the lower transverse cutting roll 3 and the upper transverse cutting roll 3 are connected to a chain in the same manner as the above-mentioned feed roll 1. are connected. Each of the rolls 1, 2, and 3 has a diameter of about 300 mm and a length of about 600 mm, and the blades 13 of the transverse cutting roll 3 have a height of 30 mm and an interval of about 40 mm. Also, the interval between the rotary blades 12 on the vertical cutting roll 2 is 15
It is about mm. In the horizontal cutting rolls 3, 3, the blades 13 of the upper and lower stages are shifted so that the blades 13 of the lower horizontal cutting roll 3 are positioned between the blades 13 of the upper horizontal cutting roll 3, and their trajectories overlap. There is. A hopper 5 whose inclination angle is variable by a hydraulic cylinder 22 is disposed in the front stage of the feed roll 1, and a net body 6 is disposed in a tilted manner in the rear stage of the cross-cutting roll 3. The lower end of the net body 6 is fixed, and the other free end engages with a protrusion 14 attached to the lower transverse cutting roll 3, so that the free end becomes the protrusion 14 with each rotation of the transverse cutting roll 3. It is driven and causes vibrations. A screw-shaped conveyor 7 whose axial direction is the same and parallel to the rolls 1, 2, and 3 is installed below the net body 6. This conveyor 7 also uses a hydraulic motor as a power source.

However, this waste material cutting machine is not only moved by wheels 10 attached to a chassis 9, but also loaded into a vehicle such as a dump truck, and uses the hydraulic pressure of a hydraulic pump installed in this vehicle to control the hydraulic pressure of each part. Motor 20, hydraulic cylinder 2
For this purpose, a pipe joint is attached to each hydraulic motor 20 in advance. The waste material is loaded onto a car and transported to a house demolition site, where it is then cut into pieces.The waste material is transferred from a hopper 5 set at an appropriate angle by a hydraulic cylinder 22 to a vertical cutting roll 2 via a feed roll 1. , and sent to the transverse cutting roll 3. On the vertical cutting roll 2, the waste material is cut vertically by rotary blades 12 from above and below, and then on the horizontal cutting roll 3, it is cut into pieces by upper and lower blades 13. The waste material thus cut into small pieces of about 10 mm square is discharged onto the net body 6. As mentioned above, since the net body 6 vibrates with each rotation of the transverse cutting roll 3, small pieces, cutting waste, and powder are removed from the net body 6 to the conveyor 7 below.
After being collected in one place by a conveyor 7, it is transferred to a transport vehicle. feed roll 1
Each pair of rolls 1, 2, and 3, including the vertical cutting roll 2 and the horizontal cutting roll 3, are each spring-biased to the other, so that they can be cut depending on the thickness and hardness of the waste material to be input. move up and down. This vertical movement changes the amount of compression of the spring 8, and the cutting force exerted by the spring biasing force changes. This cutting force can also be adjusted using the adjustment bolt 15. The waste material that passes through the transverse cutting roll 3 without being completely cut due to the presence of extremely hard knot-like parts and is discharged without passing through the mesh of the net body 6 may be fed again from the hopper 5. Pillars and other materials are reused, so they are not cut into small pieces, but bars and other materials are cut to the appropriate thickness using another cutting machine and then fed into this waste material cutting machine, or scrap materials are cut into pieces. The rotary blade 12 of the vertical cutting roll 2 in the cutting machine is replaced with one suitable for this purpose, and the thickness is reduced to an appropriate thickness, followed by finely cutting. In this embodiment, the power source is a hydraulic motor 20, and when mounted on a vehicle equipped with a hydraulic pump such as a dump truck, the motor can be operated simply by connecting to the hydraulic pump via a pipe joint. However, an electric motor may be used, and the hydraulic motor 20 may also be provided on the vertical cutting roll 2. In any case, if it is possible to use a power source such as a hydraulic motor installed in a dump truck, then by installing it on that vehicle, it will be extremely easy to transport the house to the demolition site and operate it. Moreover, if the discharge conveyor is a screw conveyor parallel to the axial direction of the rolls, the waste materials cut into small pieces will not be scattered and will be ensured to accumulate in the designated position. By vibrating the mesh, the function of the mesh as a sieve is more reliably demonstrated, and it becomes extremely easy to sort out the waste material that remains uncut in terms of hardness, thickness, etc.

As described above, in the present invention, by simply inputting the waste material from the hopper, the waste material is first sent between the vertical cutting rolls by the feed roll, and then cut vertically by the rotary blade of the vertical cutting roll. After this, the waste material is cut horizontally into small pieces by the blades of the transverse cutting roll, and the small pieces that pass through the net are collected in one place on a conveyor, and the waste wood is disposed of. It has the advantage of being quick and efficient, and since each roll is spring-biased from one side to the other, there is no risk of damage to the rotating blade or the blade due to differences in the thickness or hardness of the scrap material. The waste material can be cut with an appropriate cutting force without being hit or unable to be fed.
