RU129845U1 - VEGETABLE PRODUCT GRINDER - Google Patents

Abstract

A fruit and vegetable shredder containing a bed, a housing fixed to it with a grinding chamber, a loading neck and an unloading window, as well as a gear motor with a drive shaft, characterized in that the knife wall moves along the guides inside the housing towards an antislip support, repeating the shape of the zigzag working surface knife wall, carried out by a crank mechanism, driven by a gear motor, while the knives in the knife wall are located at a sliding angle of 30 °.

Description

The utility model relates to agriculture, is intended for chopping fruits and vegetables and can be used in individual farms and peasant farms, as well as in the food industry.

Known root crop chopper, in which the body has a grinding chamber in the form of a parallelogram, and the knife walls are made with the possibility of cyclic movement along the support rollers and guide grooves towards each other due to the reciprocating movements of the handle along the guide fingers and the movable axles of the articulated joint sliding along the body cuts two shoulders levers having upper stops, while the knives in the knife walls are mounted vertically at the cutting angle of the machined material yala with slip (RF Patent No. 2369083, A01F 29/08, B02C 18/02, 2006).

The disadvantage of this device is that to move the knife walls, a complex multi-link lever mechanism is used, which leads to excessive energy costs while ensuring its operation. Moreover, the use of a manual drive is inefficient and reduces the performance of the device.

Known root crop chopper having a loading neck, a housing, a rectangular grinding chamber, hydraulic cylinders, cutting knives, grouped into two oppositely located walls. In this case, one knife wall is fixed motionless, and the second is made with the possibility of cyclic movement along the guides using a hydraulic actuator (RF Patent No. 2162284, A01F 29/08, V02C 18/02, 2001).

The disadvantage of this grinder is that the speed of cyclic movement of the movable knife wall along the guides towards the stationary one is too low, which leads to crushing of the processed material, which is strongly deformed before the start of cutting, and as a result is crushed with increased energy costs. Also, the low cutting speed does not provide high productivity of the device, and the applied type of normal chopping cutting affects the increase in energy consumption of the technological process.

The objective of the utility model is to reduce energy costs and increase device performance.

The problem is solved in that the movement of the knife wall along the guides inside the case towards the opposing support, repeating the shape of the working surface of the zigzag knife wall, is carried out by a crank mechanism, driven by a gear motor, while the knives in the knife wall are located at a sliding angle of 30 ° .

The technical result provided by the given set of features is to reduce the energy costs of the cutting operation due to the location of the knives in the zigzag knife wall at a sliding angle of 30 °, as well as to increase the productivity of the device due to the fact that the movement of the knife wall along the guides inside the casing towards the anti-abrasion support, repeating the shape of the working surface of the knife wall, it is carried out by a crank mechanism driven by a gear motor, providing high cutting speed.

Fig. 1 shows a grinder of fruits and vegetables, a general view, in Fig. 2 - a grinder of fruits and vegetables, a top view AA.

The device comprises a frame 1, a housing 2 attached thereto with a grinding chamber 3, a loading neck 4 and an unloading window 5, as well as a gear motor 6 with a drive shaft 7, pivotally connected to a crank 8, an adjusting nut 9, a connecting rod 10, knives 11 in knife wall 12, making reciprocating movements along the guides inside the body (not shown in the figure) towards the opposing support 13.

The device operates as follows. The processed material through the loading neck 4 enters the grinding chamber 3. By transmitting torque drive shaft 7 from the gear motor 6 to the crank 8, through the connecting rod 10, the knife wall 12 is moved along the guides (not shown) inside the housing 2 to meet the opposing support 13 The fruit and vegetable material penetrates through the knife wall, crushed into slices of the required thickness, and is removed through the discharge window 5. In this case, the protrusions of the counter support 13 enter the depressions of the knife wall 12, which leads to to complete grinding of all the material in the grinding chamber 3 and increase productivity. Due to the fact that the knives 11 are installed at an angle of cutting material with a slip, energy consumption is sharply reduced.

The use of a crank mechanism and a gear motor as a drive of the working body of the grinder provides high speed and cutting performance.

The chopper can be easily implemented in agricultural production.
