Abstract

The utility model discloses a foldable thresher which is suitable for the threshing of rice and wheat. In the foldable thresher, a main frame is fixedly connected with a roller frame and a scaffold respectively by bolts instead of the welding, and corresponding positing and supporting members are adopted to reinforce the strength and the stability of the foldable thresher; the thresher can be folded round the axial directions of (2), (3) directionally. After the foldable thresher is folded, compared with the original thresher, the quantity of crops loaded on each cart is increased by more than 65% in transit, so the transportation cost is reduced; the foldable thresher which can be hung on walls or beams to store conveniently; while in use, the bolts are fixed tightly, and the foldable thresher has the same functions as common threshers.

Description

Foldable thresher

The utility model relates to a kind of collapsible thresher, and it is applicable to the threshing of paddy and wheat.

Widely used at present; no matter be the foot-operated rice-wheat thresher that adopts gear drive or adopt flexible transmission; frame all is fixed; though thresher is not heavy; but owing to use the requirement of configuration aspects; this type of thresher is occupation of land side relatively but, adorns not enough tonnage in transit far away, and general automobile can only install to about 1/3rd of specified tonnage.And thresher belongs to the seasonal very strong tool of production, and service time is generally only about one month in 1 year.During slack season thresher is placed on indoor very occupation of land side, and is placed on outdoor easy-to-rust.Therefore, the thresher of this fixed frame both had been not easy to transportation at present, deposited keeping when also being not easy to slack season.

The purpose of this utility model is, intends designing a kind of thresher under the prerequisite that does not change its function and primary structure and threshing mode, makes its rack section have folding function, is convenient to deposit the purpose of keeping when reducing cost of transportation and slack season to reach.

In the accompanying drawing: dotted portion is the thresher perspective view; Solid line partly is the state diagram after folding.

Solution of the present utility model is at mainframe and the roller shelves position 2 that links; and and pedal point of attachment 3; the employing bolted connects; namely with the fixing welding that replaces general thresing machine of bolt; and adopt corresponding location and support member to strengthen its intensity and the steadiness when working; during work with bolted, transportation or unscrew when idle and make thresing machine directed folding around 2,3 axis directions, thus realize above-mentioned purpose.

The realization of this utility model is to utilize angle steel to do the frame of thresher, adopts bolted to connect at 2,3,5 and 6 places, when employing is done frame than the angle steel of small dimension, should do at above-mentioned position to strengthen handling, as increase weldering one steel plate etc. before boring.The diameter of bolt hole is 9mm-11mm, the diameter 8mm-10mm of bolt, and cross hang 4 both had been used for fixing rolling stand, played again thresher is hung over the double action that charge square rafter (mixing square rafter) is gone up work.By angle steel 9,7 and 8, respectively two movable positions of frame are done the location and supported processing simultaneously,, respectively the nut at 2,3,5,6 places is tightened during use, just can use as common thresher to increase steadiness and the intensity in its course of work; Transportation and then it being unclamped when on the shelf; and it is folding around the axis orientation of bolt 2,3; solid line part in shape after folding such as the accompanying drawing; the thresher frame is a symmetry with its cross section; admittedly omit the narration of its antimere, this structure both had been suitable for single threshing machine and also had been applicable to double threshing machine.

For diameter of cylinder is that 350mm, length are the single foot pedal threshing machine of 500mm, and frame all adopts the angle steel manufacturing of 3 * 30 * 30mm, the parameter of its feature technology part:

Bolt, nut 2,3,5,6 are: M10; Cross hang 4 and positioning supports 9 all adopt and frame same specification angle steel, and the major axis of cross hang is that 250mm, minor axis are 200mm, embed mutually and weld at center line and major axis 1/5th place's openings of minor axis; Support the 6 long 200mm of being, be 25 ° of fillet welding jails with perpendicular support, the lower end contacts with the extended end of foot rest to play a supportive role, and this moment, the angle with foot rest should be about 65 °, and promptly foot rest should be vertical substantially with mainframe; Location-plate 7,8 is welded in respectively on mainframe and the roller shelves, should be vertical mutually during duty, and with this angle parallactic angle of exceeding.State such as accompanying drawing dotted portion during use, this moment is fastening with bolt 2,3,5,6, can be hung on the material square rafter as thresher to work; Need transportation or when placing then with bolt 6, take off, with bolt 2,3,5 unscrew can receive as accompanying drawing solid line part shape, the frame rearview is as symmetry, its narration of Therefore, omited.

The folding back of this thresher is except that width constant (wide is 560mm), and height only is that 0.4 meter, length are 0.55 meter; Volume only is 0.123m ³Each automobile is adorned more than 65% than it former thresher more during transportation, and cost of transportation descends greatly, is convenient to again during slack season place, even can be hung on wall or the house beam, and have same usefulness in use.

Claims

1, a kind of collapsible thresher, it comprises frame, transmission device, threshing cylinder, it is characterized in that frame is orientable folding around the axis direction of point of attachment 2,3.

2, by the described thresher of claim 1.; two cross supporting frames 4 that are used to hang bucket and play stabilization about the frame that it is characterized in that it has; the connection place 5,6 of cross supporting frame and frame; and mainframe and roller shelves two interfaces 2, and two interfaces 3 of foot rest; all connect by fastening bolt; its tightness is adjustable, location-plate 7,8 and support member 9 is also arranged in order to strengthen its intensity and steadiness respectively at point of attachment 2 and 3 places.
