Secondary compression moulding device for bale

Abstract

The invention discloses a secondary compression moulding device for a bale. The device comprises a feeding mechanism, a compression cavity, a pressure maintaining cavity, a compression mechanism, a vertical pushing mechanism, a horizontal pushing mechanism, a strapping mechanism and a cutting mechanism; the bale output end of the feeding mechanism is communicated with a feeding hole disposed on a sidewall in the length direction of the compression cavity; the pressure maintaining cavity is disposed on the lower part of the end part of the compression cavity opposite with the compression mechanism and communicated with the compression cavity; the pressure maintaining cavity extends towards one end along the width direction of the compression cavity; the top part of the end part of the compression cavity at a place corresponding to the pressure maintaining cavity is connected with the vertical pushing mechanism; the end part of the non-extending part of the compression cavity is connected with the horizontal pushing mechanism; and the extending part of the pressure maintaining cavity is orderly connected with the strapping mechanism and the cutting mechanism. The secondary compression moulding device for a bale disclosed by the invention has the advantages of being low in noise, large in compression density, high in production rate and capable of producing a secondarily-compressed bale with uniform weight and good appearance; and the square funnel-shaped design of the feeding hole of the compression cavity and the arrangement of a guide boss are good for smooth feeding for bale without blockage.

Description

technical field [0001] The invention relates to a pasture processing machine, in particular to a straw bale secondary compression molding device, which belongs to the field of agricultural machinery. Background technique [0002] Due to the low density and large volume of the grass bales produced by the forage picking and bundling machine, the storage, sales and export transportation are not economical. Moreover, because the grass bales contain more air, they are prone to mildew and rot during storage. Therefore, it must be compressed twice to form a secondary bale with smaller volume and higher density. [0003] At present, the existing secondary bale compression equipment usually compresses one or two primary bales, and manually wraps or packs them after being pushed out. Although the machine is simple in structure, low in cost, and easy to move, the productivity of the equipment is low, only 1.5-2.5t / h. Operations such as handling, feeding, and packing of the second bale...
