Abstract

A root vegetables and fruits cutter comprises a body, loading hopper with electrodrive. Knives are separated from disk and fixed on it by means of threaded connection.

Description

Description of the invention

The invention relates to agricultural engineering, namely to shredders of 2 root vegetables and fruits (juicy fodder).

The well-known invention "Device for cutting root tubers" (a.s. ZO 1053781 A, AOTE29/06, 15.11.83 - published), which includes a chamber that has a spiral cross-section and is equipped with a loading hopper attached to its end and installed in the chamber with the help of a device that fixes a package of annular knives placed with a gap relative to each other, in the middle of which a disk is fixed on the shaft 70 with cantilevered radial blades attached to it, the edges of which, turned to the annular knives, are equipped with teeth placed in the gap between the latter, the edges of the blades are turned to the ring knives, placed with a gap relative to them that decreases towards the disk. Disadvantages of this invention are the complexity of the design, the high energy consumption of the grinding process, as a significant part of it must be spent on ejecting the crushed mass through the funnel. 12 The closest in substance and result to the technical solution that is claimed is the IKF-150 root tuber and fruit chopper (A.N. Pylypenko, A.V. Tymanovsky. Mechanization of feed processing and preparation in private and subsidiary farms. M.: Rosagropromizdat , 1989), which has a working body in the form of a disc mounted on the shaft of an electric motor. The disk is placed in the housing, which is attached to the flange of the electric motor and has a loading hopper shifted relative to the vertical axis on the front wall. The lower part of the case is open and forms a discharge neck. The loading hopper and the housing have a common window through which the root crops are fed to the disk. Disadvantages of this chopper include the need to pre-cut medium and large root vegetables into parts and constantly feed them into the hopper, the lack of a device for directing the root vegetables into the window and pressing them against the disk, and the lack of adjustment of the degree of grinding.

The basis of the invention is the task of improving the design of the chopper for root vegetables and fruits "by using removable knives of the cutting disc and the method of their attachment to each other and the hopper to the engine, which allows you to adjust the degree of grinding of the product, easily carry out maintenance, and provide access to the working bodies during repairs unit works.

The chopper of roots, tubers and fruits consists of an electric motor 1, removable working organs - knives o 2, disk 3, lever 4, pressure plate 5, loading hopper b, bolts 7, with the help of which the disk З and the intermediate sleeve 8 are attached to each other.

The task is solved by the fact that the working organs of the shredder are knives (Fig. 1), made separately from the disk and fixed on the latter by means of a threaded connection. For this purpose, holes 10 with a thread are made in the grooves 9 of the disk C (Fig. 2) H. 3o In the proposed design, it is possible to use knives with different pitches of the blades (Fig. 3, 4), which allows you to adjust the degree of grinding of the product.

In order to prevent injuries to the operator's hands and to protect against possible product fragments flying out and timely delivery of the product being crushed to the working bodies, a pressure plate 5 (fig. 1) made of sheet steel is provided. With 50 The design of the root and tuber shredder provides easy access to the working organs of the device with the use of a removable front wall of the hopper, which is attached to the latter with bolts or other

With" removable connections. This is necessary for changing knives, maintenance or repair of working bodies.

The cutting disc is fixed on the shaft of the electric motor with the help of a threaded connection made on an intermediate sleeve, which allows for quick assembly and disassembly of the disc.

The almost completely collapsible design of this unit makes it easy and convenient to transport it in a compact package. ka Shredder for root vegetables and fruits works as follows. The rotational movement from the shaft of the electric motor 1 is transmitted through an intermediate steel bushing to the disk C on which the knives 2 are fixed. The product intended for crushing is loaded into the hopper 6 and pressed by the lid 5, thanks to which it enters the lower part of the hopper 20 where it is crushed by the working bodies. The crushed mass is thrown out through the open lower part c (mouth) of the hopper to the outside. After grinding the entire portion of the product, the next one is loaded into the hopper.

Claims (5)
