Embodiment Construction
[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0039] Such as Figure 1-8 As shown, the present invention provides a pre-pressing and shaping device for an upper-feeding square bale straw baler, including a receiving hopper 100, which is arranged above the pre-pressing chamber 200; The chamber housing 210 is fixedly connected. One side of receiving hopper 100 is provided with feed inlet 110, and the side plate 120 of receiving hopper 100 is set as screen mesh structure, is conducive to aeration and discharges the soil particle that is mixed in the stalk.
[0040] Two vertical slide grooves 212 are respectively symmetrically provided on the left and right side plates 211 of the said precompression chamber housing 210; Two vertical chute 212. The first moving bracket 220 and the second moving bracket 221 are arranged sym...

The invention discloses a pre-compression shaping device for an upper feeding type rectangular straw bale baler. The pre-compression shaping device comprises a feed receiving hopper, a pre-compressionchamber shell, two moving supports, a first compression roller and a second compression roller, wherein the pre-compression chamber shell is arranged at the lower part of the feed receiving hopper; aplurality of vertical chutes are respectively symmetrically arranged in two opposite side plates of the pre-compression chamber shell; the two moving supports are respectively symmetrically arrangedat the outer sides of the two opposite side plates of the pre-compression chamber shell; two ends of the first compression roller respectively penetrate through the vertical chutes located at the twoside plates of the pre-compression chamber shell and are rotatably arranged on the two moving supports; the second compression roller is parallel to the first compression roller; the first compressionroller and the second compression roller can synchronously rotate in opposite directions and each comprise a rotating shaft, a plurality of supporting rods and a plurality of working plates; one endof each supporting rod is detachably connected with and arranged on the corresponding rotating shaft; an angle is formed between each two adjacent supporting rods; and each working plate is fixedly connected with and arranged at the other end of one corresponding supporting rod. The pre-compression shaping device for the upper feeding type rectangular straw bale baler provided by the invention hasthe advantages of good shaping effect and compression uniformity to straw.
Description
technical field [0001] The invention belongs to the technical field of straw compression machinery, in particular to a pre-pressing and shaping device for an upper-feeding square-bale straw baler. Background technique [0002] The main working process of the square baler straw baler includes six processes of straw picking and crushing, conveying, pre-pressing and shaping, compacting and shaping, knotting, and baling. The main function of the pre-pressing and shaping device is to make the crushed straw form a A regular shape with a certain density. Due to the characteristics of looseness, low density and large compression deformation of the picked and crushed straw, the straw baler especially needs to pre-press and shape the straw, and then carry out compaction and shaping to produce a uniform density of straw bales, especially The hydraulic large square baler requires upper feeding pre-pressing shaping technology. The traditional square baler mostly adopts the bottom-feedi...
