Abstract

The utility model discloses a rotor of a hammer recrusher. The rotor of the hammer recrusher comprises a main shaft, two end surface disks arranged at two ends of the main shaft, a plurality of middle disks sheathed on the main shaft and positioned between the two end surface disks, and a plurality of hammer bodies uniformly arranged at intervals along the radial outer sides of the middle disks, wherein the radial inner sides of the end surface disks are axially and fixedly connected with the radial inner sides of the plurality of middle disks by fasteners; the hammer bodies are arranged at intervals along the axial direction; a plurality of mandrels respectively penetrate through the end surface disks, the plurality of middle disks and the inner ends of the hammer bodies; two ends of each mandrel are fixedly connected with the end surface disks at two ends of the main shaft; two sides of the inner ends of the hammer bodies are respectively and fixedly connected with the adjacent end surface disks and the adjacent middle disks to form a plurality of hammer body groups; a plurality of spacer bushes are arranged between every two adjacent hammer body groups; and the spacer bushes are respectively sheathed on the mandrels. In the utility model, the spacer bushes are additionally arranged between every two adjacent hammer body groups, therefore, the welding deformation of each disk is reduced, the size precision of the axial space between every two adjacent hammer bodies is ensured effectively and the installation positioning precision of a blade on each hammer body is improved.

Description

The hog rotor

Technical field

The utility model relates in a kind of wood-based plate or the paper industry equipment that raw material is carried out break process, and especially a kind of rotor of hog belongs to the wood processing equipment technical field.

Background technology

In wood-based plate or paper industry, hog is a kind of equipment that bark, chump, small wooden etc. is carried out break process.As shown in Figure 1; Existing hog comprises rotor assembly 20, the charging aperture 30 that is positioned at support 10 upper ends that is arranged on support 10 middle parts, the bed plate in a row 40 that is fixed on support 10 1 middle side parts; Rotor assembly 20 radially is provided with the tup body group of being made up of a plurality of tup bodies 4; A plurality of tup body groups axially are spaced respectively; Form between the tup body blade 41 of the multi-disc carbide alloy of fixing respectively on a plurality of tup body groups and the bed plate 40 in a row and shear pair, the gap is less between the two, so that cut off timber.During fragmentation timber, timber gets into bed plaves 40 upsides through charging aperture 30, broken timber under the shearing force effect between the tup body blade 41 of bed plate 40 and rotation.

The rotor assembly of existing hog comprises the end face disk that is arranged on the main shaft two ends, be sleeved on a plurality of intermediate discs between the end face disk on the main shaft, be arranged on a plurality of tup body groups of intermediate disc radial outside, and tup body the inner is welded into a plurality of tup body groups with adjacent end face disk or intermediate disc respectively.Each tup body group is spaced vertically, and it is inner that many single mandrel are passed end face disk, a plurality of intermediate disc and tup body respectively.Because being prone to the generation local buckling with the tup body during welding of end face disk and intermediate disc is out of shape; Cause the axial spacing between each tup body inconsistent, interval error can reach 2mm, and the welding difficulty is big; Postwelding is difficult to proofread and correct; Finally cause interfering between rotor assembly assembling back tup body blade 41 and the bed plate 40, influence the hog rotor and run well, can't broken timber.

Summary of the invention

The purpose of the utility model provides a kind of simple in structure, hog rotor that can reduce end face disk and intermediate disc welding deformation amount; This rotor can guarantee effectively that the axial spacing between each tup body is consistent, and avoids interfering between tup body blade and the bed plate normal operation that influences the hog rotor.

The utility model is achieved through following technical scheme:

A kind of hog rotor; Comprise main shaft, be arranged on the main shaft two ends the end face disk, be sleeved on the main shaft and a plurality of intermediate discs between the end face disk, a plurality of tup bodies of evenly at interval being provided with along the intermediate disc radial outside; The end face disk is connected through several fastening screw axial restraints with a plurality of intermediate discs; Each tup body is spaced vertically; It is inner that many single mandrel are passed end face disk, a plurality of intermediate disc and tup body respectively, and the axle two ends are fixedly connected with the end face disk at main shaft two ends, and the inner both sides of tup body are fixedly connected into a plurality of tup body groups with adjacent face disk, intermediate disc respectively; Be respectively equipped with a plurality of spacers between said each tup body group, said spacer is set on the axle.

The utility model is simple in structure, between each tup body group, sets up spacer, has improved the rigidity of end face disk and intermediate disc; When on disk, welding the tup body; Can reduce the welding deformation amount of end face disk and intermediate disc, thereby effectively guarantee each tup axon to the spacing dimension precision, tup body postwelding axial spacing error is reduced to 0.4mm by original 2mm; Improved the dress cutter positioning accuracy of tup body blade; Can not interfere between tup body blade and the bed plate, guarantee that the hog rotor runs well, help cutting off smoothly and broken timber.

Advantage of the utility model and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.

Description of drawings

Fig. 1 is the structural representation of existing hog;

Fig. 2 is the front view of the utility model;

Fig. 3 is the right view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Like Fig. 2, shown in Figure 3; The utility model comprises main shaft 1, be arranged on the end face disk 2 at main shaft 1 two ends, be sleeved on that 7 intermediate discs 3 between end face disk 2, each disk diameter evenly are provided with 6 tup bodies 4 laterally at interval on the main shaft 1; Tup body 4 inner both sides are welded into a plurality of tup body groups 400 respectively with adjacent face disk 2, intermediate disc 3 respectively; Each tup body group 400 is passed 3 screw rods 5 between axially, and is connected with nut 6 axial restraints; 6 single mandrel 7 are passed end face disk 2, intermediate disc 3 and tup body 4 the inners of each tup body group 400 respectively; Axle 7 two ends are fixedly connected with the end face disk 2 at the utility model two ends through shaft block ring 8, respectively are provided with 6 spacers 9 that are set on the axle 7 between each tup body group.Like this, when on disk, welding tup body 4, can reduce 4 welding deformation amounts of end face disk 2 and intermediate disc, avoid interfering between tup body blade and the bed plate.

Except that the foregoing description, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
