Description

The utility model relates to the field of devices for grinding materials and can be used for grinding bulk materials, for example, feed, mowed grass, fallen leaves, etc., mainly used in farms or in everyday life.

A technical solution is known, consisting in the implementation of the grinder with a removable hopper, loading pipe, grinding chamber, limited by a cylindrical sieve. A distinctive feature of which is the vertical arrangement of the drive motor, the loading elements are made in the form of a pipe, the longitudinal axis of symmetry of the loading tube is inclined to the longitudinal axis of symmetry of the motor shaft at an angle from 40 to 60 ° (Patent RU 103310 (U1). The disadvantage of this technical solution is lack of ability to move it, inconvenience in maintenance and operation.

The technical solution is also known, consisting in the performance of the chopper containing a support element with a motor fixed relative to it, on the output shaft of which there is a chopper, a working chamber limited by a perforated shell covering the chopper, and an end cap. A distinctive feature of the device is the implementation in the end cover of at least one hole for suction of air into the working chamber (Patent RU 93301 (U1)).

The disadvantage of this grinder is the inability to process with it feed, mowed grass, fallen leaves.

Closest to the claimed technical solution is the solution, which consists in the fact that in order to enable the shredding of paper, cardboard and multilayer paper bags, the device is equipped with additional rotor knives, slotted holes are radially made in the side surface of the chamber (Patent RU 90355 (U1)).

A disadvantage of the known shredder is its static nature, design complexity, inconvenience in maintenance.

The task to be solved by the claimed utility model is directed to a simplified design, providing the possibility of free movement, ensuring safe and convenient operation.

To accomplish this task, a design of a mobile crushing device is proposed that allows you to freely move it effortlessly to any distance due to the wheels and handles installed on the platform, ensure operational safety due to the existing grating - classifier, adjust the size of the resulting crushed mass by changing the distance between cross jumpers on the grill - classifier, to remove the crushed mass from the working area due to the exhaust fan. The proposed mobile device for crushing contains: housing - 1; grid - classifier - 2; boot part - 3; working part - 4; platform - 5; rotor - 6; rotary knife - 7; exhaust fan - 8; bearing support - 9; drive - 10; rotor drive pulley - 11; V-belt transmission belt - 12; output hole - 13; wheels - 14; handle - 15.

The technical result is achieved through the use of a simplified device design, a grating - classifier dividing the housing into a working and loading part, located in the working part of the rotor with a rotary knife and an exhaust fan mounted on it, platforms with wheels and handles. The design of the crushing device of the proposed design can significantly reduce the complexity of its manufacture, reduce the cost of its production, adjust the size of the crushed mass, ensure safety and ease of use, as well as use the drive on an electric or other type of fuel.

A mobile crushing device operates as follows, bulk material is placed in the loading part 3, which, passing through the grating - classifier 2, enters the working part 4. The drive 10 creates a torque that is transmitted through the V-belt transmission belt to the rotor drive pulley 11, and then on the rotor 6. The rotating rotor 6, allows the rotary knife 7, to make rotational movements, due to which the granular material is crushed. Bulk material crushed by a rotary knife 7, falls on the lower surface of the working part, from where the exhaust fan 8, removes the crushed mass from the working part 4, through the outlet 13, to the outside.

The mobile crushing device easily moves due to the platform 5, with the housing 1 mounted vertically on it, which has wheels 14 and a handle 15.
