CN2344958Y - Thrust harvester - Google Patents

Abstract

The utility model relates to a thrust harvester which comprises movable scissors, fixed scissors, shift forks, skid-proof gears, a frame, a thrusting rod, etc., wherein the movable scissors are connected with the shift forks, balance wheels are arranged on both ends of each of the shift forks and can be inserted between the skid-proof gears on power wheels, and the skid-proof gears of the two power wheels are alternatively and correspondingly arranged. The thrust harvester carries out point friction by using the skid-proof gears of the power wheels which rub the balance wheels which are provided with the shift forks and are inserted in the skid-proof gears. Therefore, hand thrust saves labor, the cutting rate of the movable scissors is improved, and working processes are saved.

Description

The thrust grain header

The utility model relates to agricultural mechanical field, especially a kind of thrust grain header.

At present, the kind of the agricultural grain header of sale is more on the market.Disclose a kind of " hand reaper " in Chinese patent 94236202-0, this grain header is to be made of parts such as push rod, guide wheel, guide plate, power rail, last lower shearing plate, bearing supports; The surface and the inboard of guide wheel are equipped with tooth, and the two ends of power rail lay respectively at the interior between cog of two-wheeled; Rotate guide wheel, power rail is reciprocating and be converted into the round shearing motion of upper and lower shear by driving lever between internal tooth.Though this grain header has improved efficiency, has reduced labour intensity; But still there is following shortcoming in it: 1. the concave surface of guide plate makes swinging to that the straw cut off by upper and lower shear can not be orderly be cut wheatland, even has that straw is plugged, the phenomenon of lower shearing plate; 2. assembly structure is unreasonable, uses hard.In Chinese patent 96221896-0, disclose a kind of " hand-push type grain header " its structure by handgrip, push rod, wheel, lay bar, chain wheel, support, baffle plate, power rail, branch straw, fuselage, moving, decide parts such as shear and form, push rod links to each other with a side of fuselage.Power rail, wheel form movingly by axle, bearing and fuselage, and wheel surface has anti-slop serrations, inboard dynamic tooth; The another side of fuselage connects decides shear; The two ends of power rail occupy respectively in the power between cog, and the power rail lug boss cooperates formation fork shift etc. with the shear recess; This grain header has been set up the lay structure and has been separated the straw device, has improved the rotating mechanism and the guide plate of guide wheel, but its weak point is the power tooth friction of its power rail and wheel inner surface, and its frictional contact surface is big, so require great effort during use, cutting frequency is low.

The purpose of this utility model is for a kind of its moving power transmission arrangment of cutting that improves on the basis of Chinese patent 96221896.0 is provided, change the line friction at the internal tooth frictional power bar two ends of wheels and insert the some friction that the band in it is dialled plug in escapement for the anti-slop serrations friction that utilizes power wheel, laborsaving, the moving cutting frequency of cutting of hand push improves, manufacturing procedure is economized, the more convenient thrust grain header of technology thereby can make.

The purpose of this utility model can realize by following measure:

A kind of thrust grain header, contain moving cut, cut surely, dial insert, anti-slop serrations, vehicle frame, push rod etc.; Moving cut to be connected with to dial insert, be provided with escapement dialling the two ends of inserting, escapement can insert between anti-slop serrations on the power wheel, the anti-slop serrations correspondence of two power wheels is staggered and arranges.

The utility model has advantage under the duty compared to existing technology:

The utility model utilizes the anti-slop serrations of power wheel, between its anti-slop serrations, put into band and dial the escapement of inserting, and the corresponding staggered characteristics of the anti-slop serrations that utilizes power wheel and the escapement that rubs drive dial insert reciprocating, thereby drive the moving reciprocal shearing of cutting, this structure is a friction structure, can be laborsaving, improve cutting frequency, but and simplified processing process, reduce manufacturing cost.

The utility model has concrete structure to be provided by the following drawings:

Fig. 1 is a structural representation of the present utility model

The moving 2-that cuts of 1-dials slotting 3-escapement 4-power wheel

5-anti-pulley 6-adds frame 7-push rod 8-and cuts surely

Fig. 2 is the anti-slop serrations of power wheel of the present utility model and the transmission schematic diagram of escapement

The 9-fork

The utility model is also incited somebody to action in conjunction with the accompanying drawings, and 1,2 embodiment are described in further detail:

With reference to Fig. 1,2, a kind of thrust grain header, contain moving cut 1, cut 8 surely, dial insert 2, anti-slop serrations 5, vehicle frame 6, push rod 7 etc.; Moving cut to be connected with on 1 to dial insert 2, insert 2 two ends and be provided with escapement 3 dialling, be connected with fork 9 on the escapement 3, an end of fork 9 links to each other with the baffle plate of grain header, the other end can stir slotting 2; Escapement 3 can insert 5 of anti-slop serrations on the power wheel 4, and anti-slop serrations 5 correspondences of two power wheels 4 are staggered arranges, and promptly the anti-slop serrations 5 of a power wheel 4 is at two anti-Weihe between cog of another power wheel 4; When hand push push rod 7, power wheel 4 rotates, and the anti-slop serrations 5 friction escapements 3 on it make escapement 3 reciprocating, and the fork 9 on the escapement 3 is stirred and inserted 2, makes reciprocal shearing motion thereby drive moving cutting.

Claims (1)

1, a kind of thrust grain header contains and moving cuts (1), cuts (8) surely, dials and insert (2), anti-slop serrations (5), vehicle frame (6), push rod (7) etc.; It is characterized in that moving cut to be connected with on (1) to dial insert (2), be provided with escapement (3) dialling the two ends of inserting (2), escapement (3) can insert between anti-slop serrations (5) on the power wheel (4), anti-slop serrations (5) correspondence of two power wheels (4) is staggered and arranges.
