Abstract

The utility model discloses a multipurpose toothed harrow which can be matched with a small walking tractor or a small four-wheel tractor, and the utility model is composed of a hanging and connecting device, a traction frame, a frame, spiked teeth, etc. The traction frame is hinged with the hanging and connecting device through a longitudinal horizontal shaft, a vertical inserting hole arranged on the hanging and connecting device is hinged with the traction latch of a tractor, and backward slope angles are arranged on the teeth; besides, a loading device arranged on the frame can be used for loading heavy articles. The utility model can quickly adapt to the condition of earth surface, the steering of the utility model is flexible, and the functions of crushing the earth and burying grasses of the teeth are favorable; the working resistance of the utility model which has high work efficiency is small; a dry field and a paddy field can be harrowed, and the qualified formal product of the utility model has been successfully produced, and the utility model has the advantages of good performance and low cost.

Description

Multirpupose toothed harrow

The utility model provides a kind of and the supporting novel farm implements of small tractor.

China has had more than 700 ten thousand of hand tractor and tractor with small four wheels, and these small tractor ploughing effects are better, because well behaved match plough is arranged.The difficulty but small tractor is used to rake the soil level, reason is to lack the supporting rake that is suitable for.The peasant household that has small tractor at present carries out tillage operation with the traditional wooden rake of tractor-drawn, its hack poor performance, and efficient is low.Spike-tooth harrow a kind of and walking tractor matching occurs recently, this rake and hand tractor are rigidly connected, and can not relatively rotate between rake and the main frame, thereby turn to difficulty, and spike-tooth easily twines grass, easily sinking etc. during the rake paddy field.

The purpose of this utility model is the spike-tooth harrow that a kind of function admirable will be provided, and is used for hand tractor and tractor with small four wheels supportingly, can harrow the nonirrigated farmland and can harrow the paddy field again.

The utility model mainly is made up of articulated device, hitch frame, framework, spike-tooth; Hitch frame cuts with scissors knot with the vertical equity axle mutually with articulated device; Articulated device is provided with vertical pin hole so that cut with scissors knot with latch mutually with tractor; Spike-tooth recedes in order to taking off grass and reducing working resistance.Though the utility model structure is simple, and service behaviour is very good.

Fig. 1 is many front view and vertical views with spike-tooth harrow, below in conjunction with Fig. 1 its concrete structure and service behaviour is described.

(7) are framework among the figure, the front of framework (7) is connecting hitch frame (4), hitch frame (4) cuts with scissors knot with articulated device (2) mutually with vertical equity axle (3), vertical pin hole (1) is arranged on the articulated device (2), hole (1) is to be used for cutting with scissors knot mutually with the traction latch of tractor, spike-tooth (5) is installed by bottom at framework (7), spike-tooth (5) has inclination angle backward, its inclination angle is preferably in 15 degree～50 degree scopes, adopt the meaning of said structure to be: because hitch frame (4) cuts with scissors knot with articulated device (2) mutually with vertical equity axle (3), the framework (7) of rake can be swung around the vertical equity axle, can improve the adaptability of rake the face of land; Articulated device (2), makes between rake and the tractor and can rotate around bolt axle on the traction latch of tractor by vertical pin hole (1) hinge knot, and whole unit is turned nimbly and freely in the field; The hypsokinesis of spike-tooth (5) reduces its working resistance; the hack performance improves; weeds are easy to come off and be pressed into earth; the spike-tooth hypsokinesis also can be subjected to the upwards counter-force of soil with the down force of balance rake; very favourable to paddy-field-working; upwards under the counter-force effect rake is slipped over from above when running into hard soil block, play the effect of protection spike-tooth and limit load.

Load carrying device (8) is set on framework (7), after installing weight additional on the load carrying device (8), will increases the hack power of spike-tooth (5).

In framework (7) bottom or front planker (6) can be set, make rake can be used for the operation of mud field.

The utility model entrusts cooperating plant to trial-produce formal product successfully by the inventor, has good working performance and lower manufacturing cost.
