The utility model adopts the technical proposal that:
the utility model provides a movable antiwind thresher of spike tooth, includes the main shaft, main shaft both ends fixedly connected with fixed disk, is connected with the spike pinion rack between two fixed disks, spike pinion rack both ends connect respectively on two fixed disk lateral walls, the spike pinion rack prolongs main shaft axis direction and sets up, the spike pinion rack prolongs fixed disk circumference and evenly is provided with a plurality ofly, the fixed disk prolongs main shaft axis direction and evenly is equipped with a plurality of through-holes, be provided with fixing bolt in the through-hole, fixing bolt's screw thread portion from interior to exterior passes the through-hole, fixing bolt's screw thread portion is connected with the spike tooth, spike tooth outer fringe diameter is greater than the through-hole diameter, the spike tooth passes through fixing bolt fixed connection on the spike pinion rack.
Furthermore, a cylindrical section is arranged between the threaded part and the head part of the fixing bolt, and the cylindrical section is rotatably connected in the through hole.
Furthermore, a fixing pin is arranged at the joint of the nail teeth and the fixing bolt, and the fixing pin penetrates through the nail teeth and the thread part of the fixing bolt.
Further the lateral wall of two fixed disks on evenly seted up a plurality of bolt holes, the nail tooth board both ends pass through bolt fixed connection in the bolt hole of two fixed disks.
The utility model has the advantages that:
1. the spike teeth are movable and can freely move in a certain space, so that the straws are effectively prevented from being wound at the two ends of the main shaft and on the spike teeth;
2. the spike teeth are replaceable, so that different types of grains can be threshed by replacing the spike teeth, and the utilization rate of the threshing roller is improved;
3. the density degree of the nail teeth and the nail tooth plates can be adjusted, so that threshing can be performed on different types of grains;
4. simple structure, the practicality is strong, and economic effect is good.
Drawings
FIG. 1 is an isometric view of the present invention;
fig. 2 is a partial sectional view of the spike-tooth connection part of the present invention.
In the figure: 1. the novel nail rack comprises a main shaft, 2 parts of an end cover, 3 parts of a nail toothed plate, 4 parts of a fixing bolt, 401 parts of a cylindrical section, 5 parts of nail teeth and 6 parts of a fixing pin.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:
a movable spike-tooth anti-winding threshing device comprises a main shaft 1, wherein fixed disks 2 are fixedly connected to two ends of the main shaft 1, a spike-tooth plate 3 is connected between the two fixed disks 2, two ends of the spike-tooth plate 3 are respectively connected to the side walls of the two fixed disks 2, the spike-tooth plate 3 is arranged along the axis direction of the main shaft 1, a plurality of spike-tooth plates 3 are uniformly arranged along the circumferential direction of the fixed disks 2, the fixed disks 2 are uniformly provided with a plurality of through holes along the axis direction of the main shaft 1, fixing bolts 4 are arranged in the through holes, thread parts of the fixing bolts 4 penetrate through the through holes from inside to outside, thread parts of the fixing bolts 4 are connected with spike-teeth 5, the diameter of the outer edges of the spike-teeth 5 is larger than the diameter of the through holes, the spike-teeth 5 are fixedly connected to the spike-tooth plate 3 through the fixing bolts 4, the main shaft 1 is rotatably connected to a power output device of a combine harvester, the main shaft 1 is rotated to drive the fixed disks 2 to rotate, so as to drive the spike-tooth plate 3 and the spike-tooth 5 connected to rotate, form the same work of traditional roll shape, because spike tooth 5 passes through 4 fixed connection of fixing bolt on spike pinion rack 3, consequently can select the quantity of installation spike tooth 5 and adjust the density degree of spike tooth 5 on spike pinion rack 3 according to the demand of different cereal, through spike tooth 5 of 3 fixed connection of spike pinion rack, thereby make and leave the space between the spike pinion rack 3, be convenient for connect and the operation work of spike tooth 5, simultaneously because the easy winding of straw is difficult for the clearance on spike tooth 5, if take place the winding phenomenon of straw, the accessible is dismantled spike tooth 5 and is cleared up fast.
