Description

The corn stalk machine for cutting green stubble

The utility model relates to a kind of farm implements, specifically a kind of device that crop straw and root stubble are pulverized.

The CN92240697 patent disclosure a kind of straw reducing mechanism, this installs by saw disc and shift fork, straw is taken in carried out sawing in the machine and pulverize.The use of this device needs earlier the straw of crops such as corn, Chinese sorghum is blown down, or before collecting machine, or discharging is neat in the ground, carries out fixed then or pulverizes with dragging supporting movable type for a short time.Therefore the preliminary preparation of pulverizing becomes a requisite artificial operation link that uses this device.

The purpose of this utility model just provides a kind of device that crop straw is directly pulverized, and to reduce the manual operation link, improves mechanization degree and operating efficiency.

The utility model is achieved in that in frame the place ahead pressing roll mechanism is set that there are backing-off cutting mechanism and intake mechanism in the pressing roll mechanism back, is shredder mechanism in the intake mechanism back.Backing-off cutting mechanism, intake mechanism and shredder mechanism all are installed on the frame, and are connected by transmission mechanism.Pressing roll mechanism overwhelms upright straw, and backing-off cutting mechanism cuts from the root stubble portion shovel on ground immediately, straw is separated with the soil, and enter into shredder mechanism along intake mechanism, implements crushing operation by shredder mechanism.This device is to match with small tractor, and utilizes the transmission mechanism of the power drag for a short time and this machine to realize the operation of each several part.

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

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

Fig. 2 is the structural representation of this device latter half behind the importing plate of extracing in the intake mechanism.

As shown in Figure 1, 2, this device includes several parts such as pressing roll mechanism, backing-off cutting mechanism, intake mechanism, shredder mechanism and transmission mechanism.Pressing roll mechanism is to be installed on the front end of support bar 25 by cylinder 26 by the bearing 27 of its both sides at device foremost, and the rear portion of support bar is fixed on the frame 1.Frame 1 is to be welded into a frame structure with angle steel.For saving materials, cylinder 26 can be made the both ends open formula, to weld two blocks of side plates 28 and fix central shaft, the two ends of central shaft are supported by bearing 27.

Backing-off cutting mechanism is a termination perching knife 24 before two pull bars 23, and pull bar 23 penetrates in the sleeve pipe 22 that joins with frame 1 bottom.Can make perching knife keep low flat entrance angle like this, and prolong ground substantially and implement backing-off cutting.Two pull bars, 23 rear ends are socketed on two eccentric wheels 18 the via pins rear end that connects two rocking bars, 20, two rocking bars 20 respectively.There is axis 19 at the center of eccentric wheel 18, is fixed on the frame 1 by bearing 32.Gear is equipped with in the eccentric wheel inboard of axis 19 1 ends.When the transmission mechanism driven gear rotated, axis 19 and two eccentric wheels 18 rotated, and drive rocking bar 20, pull bar 23 and perching knife 24 are done seesawed, and realize the backing-off cutting operation.As shown in Figure 2, sleeve pipe 22 rear ends can be by turning on the adjustable plate 29 that handle is positioned to weld together with frame 1.Promptly, can change the angle of sleeve pipe 22, regulate the entrance angle of perching knife thereupon by turning the up-down adjustment of handle.

The intake mechanism of this device includes and imports plate and feed roller etc.Import plate and be trapezoidal, there is backplate both sides, and feed roller Cheng Lang Ya is bar-shaped.Import plate 31 front ends and be supported on frame 1 front end, import postlaminar part and establish introducing port, promptly in two side guard plate ends overlap joint, one dull and stereotyped formation.Back shaft is arranged at the introducing port bottom that imports plate, supports the location by two oblique fulcrum bars 30 that are fixed on the frame 1, makes the importing plate be low early and high after heeling condition.The introducing port that imports plate 31 is with respect in the middle of two transversely arranged about the being feed rollers 16, and two feed rollers are fixing by two groups of bearings 12,13 of installing on frame 1.Every group of bearing also is arranged above and below, and realizes the location by two posts 11 of welding on frame 1. Pitch wheel 14,15 is housed on two feed rollers of one group of bearing inboard, right side.Under transmission mechanism drove, two feed rollers relatively rotated, and straw is involved in the machine, realized the feeding operation.

Shredder mechanism in this device is arranged in the feed roller rear of intake mechanism, and its structure is analogous to chopper and the chopper roller segment in the chopper mechanism substantially, specifically is two fixed disks 17 are installed on chopper roller 6 fixing chopper 21 on the fixed disk.The same with structure on the chopper machine, the chopper in this mechanism is provided with two, is distributed in side tool roller two sides.Chopper roller 6 is fixing by the bearing 7 that is installed on the frame 1, is separately installed with gear 5 and gear 8 at the two ends, the left and right sides of chopper roller.Under transmission mechanism drove, chopper roller high speed rotating drove the straw chopping that chopper will send from intake mechanism.

Transmission mechanism in this device is the core that realizes mechanism's co-operating, thereby the action for keeping accurately coordinating, and can adopt gear transmission mode.In addition and since preferably with the supporting use of small tractor, so first drive then uses belt pulley to match.Concrete structure is that belt pulley 2 is installed on frame 1 top, and belt pulley is fixed by axle and bearing 3.The gear 4 coaxial with belt pulley is meshed with the gear 5 of chopper roller 6 left ends in the shredder mechanism.Feed roller 16 lower roll right-hand members at intake mechanism are equipped with gear 9, and this gear 9 is meshed with the gear 8 of chopper roller 6 right-hand members in the shredder mechanism.This gear 9 simultaneously with backing-off cutting mechanism on the axis 19 gear of eccentric wheel installed inside be meshed.The running of this device is, belt pulley 2 power outside drives rotation down, and gear 5 engagements in coaxial with it gear 4 and the shredder mechanism make the rotation of chopper roller, and the gear 8 of chopper roller right-hand member and gear 9 engagements drive two feed rollers 16 and rotate in opposite directions simultaneously.Gear 9 also is meshed with gear on the axis 19 simultaneously, drives eccentric wheel 18 rotations, realizes the perching knife motion.

Supporting for conveniently and for a short time dragging, be welded with the beaming roller 10 that articulates with tractor in the rear end of frame 1.Utilize the hook that drags for a short time on the preceding thick stick to tangle beaming roller 10, frame 1 rear portion is lifted, the complete machine front end is supported by cylinder 26, to drag belt pulley and 2 socket of usefulness belt and the tensionings of the belt pulley on the frame 1 on the diesel powered output shaft simultaneously for a short time, be that available this machine of promotion that drags for a short time advances, realize the clear stubble and the crushing operation of straw.

This device volume is little, kilogram surplus the weight 100, be suitable for dragging for a short time promotion, it is reliable to operate steadily, and has exempted the operation of artificial felling straw, mechanization degree improves, having saved manpower, per hour can gather in crushed straw 3-4 mu, can directly deep plough in harvested soil, do not need to go manual stubble clearing, overall efficiency improves greatly again.
