Description

A kind of ditching machine

Technical field

This utility model belongs to field of agricultural machinery, specially a kind of ditching machine in arable land.

Background technology

With the propulsion of China's new countryside construction, the mechanization schedule speed of agricultural is more and more faster, for convenience farmland Cultivate, various farm machineries have begun to the visual field for coming into people, into farmland.In northern field, except being directed to It is outside the large-scale united reaper of Semen Tritici aestivi and Semen Maydiss, also various that shaping such as trench digging and the farm machinery of ridging are carried out to farmland, this A little farm machineries are cultivated for farmland and are equally played an important role.

Existing field furrower is generally the fixed monolithic furrow-opening cutter blade being obliquely installed, and on tractor, drags With furrow-opening cutter blade in field work, the soil in field is dug to the side of ditch in the case where the excavation of furrow-opening cutter blade drives for machine drawing, Limited by its structure, ditched less efficient, ditching depth can not be adjusted.Therefore remain a need for constantly innovation and improve, be allowed to more Cultivating for people is served easily.

Utility model content

The purpose of this utility model is to provide a kind of ditching machine, to solve the above problems.

For achieving the above object, the utility model proposes technical scheme be：

A kind of ditching machine, including connecting rod, front ditching knife and side ditching knife, the connecting rod are arranged on the upper of front ditching knife End, is connected with tractor, and front ditching knife is vertically arranged, and its underpart is to front curve and puts the first edge on a knife or a pair of scissors forward, and the side ditching knife has two, The both sides at front ditching knife rear are separately positioned on, are tabular wide at the top and narrow at the bottom, front ditching knife is with side ditching knife by being connected machine Structure connects, and bindiny mechanism includes the link being fixedly connected with front ditching knife and be arranged on the inside of the ditching knife of side living with side ditching knife The adjustable plate of dynamic connection, the adjustable plate are bolted with link, and adjustable plate offers 2 ~ 4 respectively with link Bolt hole, to adjust the angle between two side ditching knifes, and then adjusts trench digging width.

In this utility model, 3 ~ 5 connecting holes being connected with tractor are offered in the connecting rod, is easy to regulation to open The height of ditch machine, and then adjust ditching depth.

Further, the connecting hole for opening up in the connecting rod is 4.

In this utility model, the bolt hole opened up on the adjustable plate is 3, and the bolt hole opened up on link is 2 It is individual, disclosure satisfy that most trench digging width range, moreover it is possible to ensure that adjustable plate possesses suitable length with link.

In this utility model, the bottom of the link is set to horizontal tabular, its knife highly with front ditching knife Cusp height is consistent.

In this utility model, the top of the side ditching knife is slightly bent outwardly, and effectively can shift soil onto trench digging Both sides and prevent which from dropping back in ditch.

Compared with prior art, this utility model structure is novel, reasonable in design, can quickly excavate out appropriate depth and width The ditch of degree, prevents soil from dropping back in ditch, and effect is good, easy to use.

Top views of the Fig. 2 for this utility model embodiment.

In figure：Connecting rod 1, front ditching knife 2, side ditching knife 3, connecting hole 4, link 5, adjustable plate 6, bolt hole 7.

Specific embodiment

This utility model is further described below in conjunction with Figure of description and concrete preferred embodiment, but not because This and limit protection domain of the present utility model.

Referring to the ditching machine shown in Fig. 1 ~ 2, including connecting rod 1, front ditching knife 2 and side ditching knife 3, connecting rod 1 is arranged on The upper end of front ditching knife 2, is connected by connecting hole 4 with tractor, and the front ditching knife 2 is vertically arranged, and its underpart is to front curve And put the first edge on a knife or a pair of scissors forward, the side ditching knife 3 has two, is separately positioned on the both sides at 2 rear of front ditching knife, is flat board wide at the top and narrow at the bottom Shape, arranges in inverted V-shaped, more than 2 side ditching knife 3 of front ditching knife is connected by bindiny mechanism, and bindiny mechanism includes solid with front ditching knife 2 The link 5 of fixed connection and it is arranged on the adjustable plate 6 being flexibly connected with side ditching knife 3 on the inside of side ditching knife 3, the adjustable plate 6 It is bolted with link 5,2 bolts hole 7 is wherein offered on adjustable plate 5,3 bolts hole 7 on link, are offered, 4 connecting holes are offered in connecting rod 1.The bottom of the link 5 is set to horizontal tabular, its highly with front ditching knife 1 Nose height it is consistent, the top of side ditching knife 3 is slightly bent outwardly.

When this utility model is applied to field trench digging, select what connecting rod 1 and tractor were connected according to the actual requirements Position selects the bolt position that link 5 and adjustable plate 6 connect to adjust between side ditching knife 2 to adjust the depth of trench digging Angle, adjusts trench digging width with this, after being provided with by carry out trench digging work.

This utility model structure is novel, reasonable in design, can quickly excavate out the ditch of appropriate depth and width, prevent soil Drop back in ditch, effect is good, easy to use.
