Description

shredder

The present invention relates to a chipper, in particular to a chipper for crushing residual branches.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , a conventional shredder includes a housing unit 8 and a crushing unit 9 . The housing unit 8 includes an inlet barrel 81, a crush barrel 82, and an outlet barrel 83 connected along a crushing path 80 from back to front, and a top protrusion arranged on the top of the barrel 83. Eaves 84. The feed barrel 81 has a feed opening 811 disposed at the rear side of the crushing path 80 . The discharge barrel 83 has a discharge opening 831 disposed on a side crossing the crushing path 80 , and the discharge opening 831 extends vertically and longitudinally. The top protruding eaves 84 cover the top of the discharge opening 831 and protrude laterally. The crushing unit 9 is rotatably installed in the crushing cylinder 82 and includes several cutters 91 .

Although this existing shredder can crush a residual branch (not shown) that enters from the feed port 811 into many debris (not shown), and make the debris move forward along the crushing path 80 And thrown upwards to the discharge barrel 83, but because the discharge port 831 is not located at the front side of the crushing path 80 but is turned to the side, so the debris cannot be directly ejected and discharged forward smoothly, and will be Blocking can only stagnate in the discharge barrel 83, only a part of the surrounding debris can be discharged from the discharge port 831 on the side, and the debris that cannot be smoothly discharged will directly fall and accumulate in the crushing barrel 82 Below, after a period of time, the debris continues to accumulate and rise to the height adjacent to the crushing unit 9, which will cause blockage and affect normal operation. At this time, it is necessary to stop the machine to remove the blocked debris, so it is quite inconvenient to use.

It is therefore an object of the present invention to provide a wood chipper which at least overcomes the disadvantages of the prior art.

Therefore, the new branch shredder includes a housing unit and a crushing unit. The housing unit includes an inlet barrel, a crushing barrel and an outlet barrel connected along a crushing path from back to front, and the inlet barrel has a material inlet arranged at the rear side of the crushing path , the discharge cylinder has a discharge port arranged on the front side of the crushing path. The crushing unit includes a cutter wheel rotatably installed in the crushing cylinder, and several cutters arranged on the cutter wheel.

The effect of the present invention is that: the discharge port is arranged on the front side of the crushing path, allowing debris to be discharged directly and smoothly, which can effectively improve the problem of blocking.

Referring to Fig. 4, Fig. 5 and Fig. 6, one embodiment of the new branch shredder is suitable for crushing residual branches (not shown) such as branches and leaves, straw, bamboo and weeds into most smaller debris (not shown). The shredder includes a carrying unit 1 , a power unit 2 , a housing unit 3 and a crushing unit 4 .

The carrying unit 1 includes a platform 11, two driving wheels 12 rotatably mounted on the left and right sides of the platform 11, two driving wheels 12 mounted on the left and right sides of the platform 11 and respectively located behind the driving wheels 12. Steering wheels 13, and a handle frame 14 erected on the rear side of the platform 11 and capable of being manipulated by the user.

The power unit 2 is arranged on the top rear side of the platform 11, and includes components such as an engine, a motor, a gearbox, a pulley, etc., which can provide power for the driving wheels 12 to travel to the work field, and can provide the crushing The unit 4 is powered to crush the residual branches, but since the power unit 2 is a general prior art and not the focus of the present invention, it will not be described in detail here.

The housing unit 3 is disposed on the top front side of the platform 11 and extends backward and above the power unit 2 . The housing unit 3 includes an inlet cylinder 31, a crushing cylinder 32 and an outlet cylinder 33 connected along a crushing path 5 from back to front, and an adjustable angle is arranged on the outlet cylinder 33. The protruding eaves 34 at the top.

The material feeding cylinder 31 extends obliquely towards the front and downward to the rear side of the crushing cylinder 32, and has a material inlet 311 arranged at the rear side of the crushing path 5 for the residual branches to enter. The discharge tube 33 protrudes upwards from the top front side of the crushing tube 32, and has a discharge port 331 arranged on the front side of the crushing path 5. The discharge port 331 extends left and right and can be used for the Debris drains. Then with regard to the cylinder structure of the discharge cylinder 33, the discharge cylinder 33 has two left and right spaced side walls 332, a front wall 333 connected to the front side of the side walls 332 and provided with the discharge port 331, and a connection The rear wall 334 is on the rear side of the side walls 332 and extends from bottom to top and gradually bends forward. The top protruding eaves 34 cover the top of the discharge opening 331 and protrude forward.

The crushing unit 4 includes a cutter wheel 41 driven by the power unit 2 and installed in the crushing cylinder 32 rotatably at high speed, and several cutters 42 arranged on the cutter wheel 41 . Each of the knives 42 extends left and right and is parallel to the outlet 331 , and can be used for chopping and pulverizing the residual branch into the debris.

When in use, the residual branches are sent into the material inlet 311, and the residual branches will slide down to the crushing cylinder 32 along the feeding cylinder 31, and are constantly cut by the knives 42 quickly and crushed into these Chips are then centrifugally thrown forward and upward by the cutter wheel 41 and the cutters 42 to the discharge barrel 33 and discharged from the discharge port 331 .

To sum up, the new type chipper, by setting the discharge port 331 of the discharge cylinder 33 on the crushing path 5 and making its opening forward, the debris can be discharged directly and smoothly, and it can have excellent performance. Excellent discharge effect can effectively improve the problem of debris clogging, making the operation more rapid and convenient, so the purpose of the new model can indeed be achieved.

In addition, the new branch shredder also uses the discharge port 331 to extend left and right, the rear wall 334 extends toward the discharge port 331 in a curved arc, and the top protruding eaves 34 protrude forward to cover the discharge port. The design above the opening 331 can make the debris thrown out by the centrifugal force forward and discharge in large quantities from the wide discharge opening 331, which has the effect of smooth discharge.

But the above-mentioned ones are only embodiments of the present invention, and should not limit the scope of implementation of the present invention with this. All simple equivalent changes and modifications made according to the patent scope of the present application and the content of the patent specification are still within the scope of the present invention. Within the scope covered by this patent.
