Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an improvement of a device for shredding beet pulp for feeding.

[Prior Art] Beet pulp is a squeeze residue of beet produced in the process of producing sugar from beet, and is compression molded into a rectangular parallelepiped of about 60 kg. Beet pulp is used by dairy farmers because it has a high nutritional value as a feed and the biting of cattle is good, and usually about 10 feeds per head are fed each year. For feeding, beet pulp must be shredded to a size that cows can easily eat. In the past, beet pulp was chopped with Masakari or cut with an electric saw.
This work is dangerous and dirty, and is a heavy labor,
It was difficult to chop the beet pulp into the desired uniform size.

[Problems to be Solved by the Invention] The present invention has been made in order to solve the above problems, and an object of the present invention is to easily cut beet pulp uniformly without heavy labor. To provide a shredder.

[Means for Solving the Problems] In order to achieve the above object, the present invention adopts
A frame that holds the beet pulp so that it can be lowered but does not rotate, a rotating plate provided with a rotating blade that evenly scrapes the bottom surface of the beet pulp, a case that supports the frame and surrounds the rotating plate, and its The reason is that the shredder is composed of the discharge port provided in the case, and the rotary blade at the center of the rotary plate is made higher than the other rotary blades. The rotary plate is connected to an output shaft of an electric motor, a hydraulic motor or the like directly or via a rotation transmission mechanism.

[Operation] When a rectangular parallelepiped beet pulp is put in a frame, the high center rotary blade on the rotating plate pierces the bottom of the beet pulp, but the other low rotary blades do not reach the bottom of the beet pulp. Therefore,
When the rotary plate is rotated, initially only the center rotary blade cuts the center of the bottom surface of the beet pulp, but the peripheral speed is low, so the load at the start is also small. When the center of the bottom surface is cut, the beet pulp descends by its own weight, and all the bouds come into contact with the bottom surface to evenly cut the bottom surface of the beet pulp. In this way, the bottom surface of the beet pulp is evenly scraped off, and the fine pieces thereof are discharged from the discharge port of the shredder.

[Embodiment] The present invention will be described based on an embodiment shown in the drawings of a shredder.

As shown in FIGS. 1 and 2, the shredder 10 includes a rectangular parallelepiped frame 11 and a cylindrical case 12 attached below the frame.
And a rotating plate 13 rotatably arranged inside the case 12. A part of the outer peripheral surface of the case 12 is opened, and a discharge port 14 is provided there. The rotary plate 13 is fixed to an output shaft 16 of an electric motor 15 with a reducer. The diameter of the rotary plate 13 is equal to the length of the bottom diagonal line of the beet pulp 20. At the center of the upper surface of the rotary plate 13, a central rotary blade 17 is arranged, and a number of rotary blades 18 are spirally arranged from the central rotary blade. Case 12 is platform 19
Placed on top and the electric motor 15 is mounted below the pedestal 19.
The shredder 10 can be easily relocated with the platform 19.

Next, chopping of beet pulp will be described. First,
A rectangular parallelepiped beet pulp 20 is placed in the frame 11 of the shredder 10.
The lower half of the frame 11 is surrounded by a plate material, but the upper half is only a ridge and there is no plate material, and one side and the top surface are open, so the work of putting the beet pulp 20 inside the frame 11 is extremely easy. is there. Since the inner cross section of the frame 11 has a similar shape slightly larger than the cross section of the beet pulp 20, the beet pulp 20 can descend vertically but cannot rotate. At this time, as shown in FIG. 2, the rotary blade 17 at the center higher than the other rotary blades 18 sticks the beat pulp 20 in the center of the bottom surface of the beat pulp 20, and the other rotary blades 18 support the beat pulp 20. Does not reach the bottom. Therefore, when the electric motor 15 is started, the rotary plate 13 rotates, and the central rotary blade 17 cuts the center of the bottom surface of the beet pulp 20, but since the peripheral speed of the central rotary blade 17 is low, the starting load is also small, and therefore, The electric motor 15 starts up smoothly.

As the cutting of the center of the bottom surface of the beet pulp 20 by the central rotary blade 17 advances, the beet pulp 20 descends by its own weight, and all other rotary blades 18 contact the bottom surface of the beet pulp 20, so that the entire bottom surface of the beet pulp 20. It is cut uniformly. Although the load at this time is large, the electric motor 15 is not hindered because the starting time has already passed.

In this way, the bottom surface of the beet pulp 20 is uniformly scraped by the rotary blades 17, 18 arranged in a spiral shape, and becomes a fine fragment 21 of uniform size suitable for feeding and discharged from the discharge port 14. To be done.

[Effects of the Invention] As described above, the shredder of the present invention has a simple structure and can be relocated anywhere, and the bottom of the beet pulp can be scraped off evenly just by placing the beet pulp in the frame. ,
Uniform fine pieces of suitable size for cattle feeding are automatically obtained. Therefore, the worker is freed from the heavy and dangerous work using the conventional Masakari and electric saw.

Further, since the shredder of the present invention has a small load at the time of starting, the starting is smooth even if the starting torque of the power source is relatively small.
