Abstract

The utility model relates to a sowing machine matched with a walking tractor. Using the sowing machine matched with a walking tractor, the problem that inconvenient lifting and falling caused by the overweight of the existing sowing machine in use is solved. The sowing machine matched with a walking tractor is composed of a box assembly, a furrow opener, a machine frame, a driving mechanism, a driving thrust wheel, etc. The utility model is characterized in that the machine frame forms a T shape; the driving thrust wheel is arranged under the middle part of the T-shaped machine frame through a V-shaped swinging arm; one side arm end of the V-shaped swinging arm is hinged at the front lower part of a longitudinal rod of the machine frame, and the other side arm is connected with the middle lower part of the longitudinal rod of the machine frame by a pin. The driving mechanism is a chain-drive mechanism. The sowing machine matched with a walking tractor has the advantages of simple structure, reasonable design, labor saving for operation, and convenient adjustment.

Description

The hand steered sower of elevation (over-and-under) type

The utility model relates to a kind of sower, exactly is the sower with walking tractor matching.

Existing sower kind is a lot, also have multiple with the sower of walking tractor matching, the hand steered sower of a kind of swing lifting is disclosed as Chinese patent 96206492.0, this machine is made up of frame, kind case, seeds discharging box, plough and transmission gauge wheel etc., be characterized in: frame is a tee T twin beams frame, is provided with one between an end of central rack twin beams; The middle part excircle of axle is provided with a chuck perpendicular to axle; One end of wheel bar is located in the chuck, is provided with a guiding supporting wheel by axle on the other end of wheel bar; One end of axle extends the outside of beam, which is provided with a location ratchet, and the middle part in the same outside of beam is provided with an operating grip, which is provided with a drag-line, and the end of drag-line is provided with a loose pin, and loose pin contacts with positioning ratchet wheel; Or on the other end of central rack twin beams, fix a chuck, be provided with the wheel bar of guiding supporting wheel in the chuck.The problem of this machine is, when being in turning, needs make frame be raised to certain height by the ratchet detent mechanism; When needs are used to sow, by the ratchet detent mechanism frame is fallen, the lifting of this machine and landing are inconvenient, dumb.

The purpose of this utility model is: provide a kind of from heavy and light, the convenient, flexible hand steered sower of elevation (over-and-under) type of lifting landing.

The technical solution that realizes above-mentioned purpose is such, and the hand steered sower of elevation (over-and-under) type is made up of kind of a box assembly, frame, transmission mechanism, transmission supporting wheel, it is characterized in that:

A, frame are the T font, plant the cross bar top that box assembly is positioned at T font frame; The transmission supporting wheel is located at below the middle part of T font frame by the V-type swing arm, and a side arm end of V-type swing arm is hinged through the hinge to the lower front of the vertical pole of T font frame, and another side arm is connected in the below, middle part of the vertical pole of T font frame by pin; This side arm is provided with plural pin-and-hole;

B, transmission mechanism are chain-drive mechanism, and one on its sprocket wheel is located at an end of transmission supporting wheel, and another is by being located in the bottom of kind of case, and chain is striden on two sprocket wheels.

The utlity model has the advantage of following three aspects:

One, this machine is simple in structure, and is reasonable in design, good manufacturability.

Two, owing to adopted V-type swing arm structure, so make the lifting of transmission supporting wheel, landing very convenient.

Three, since this machine from heavy and light,, turn lightly so rapid operation is easy to adjust.

Description of drawings:

Fig. 1 is the utility model structural front view,

Fig. 2 is the utility model structure vertical view.

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

By Fig. 1, Fig. 2 as seen, the hand steered sower of this elevation (over-and-under) type is made up of kind of box assembly 1, T font frame 3, chain drive 2, transmission supporting wheel 7 and plough 9.

Plant box assembly 1 and be positioned at above the cross bar of T font frame 3, its cross bar below is provided with plough 9; Two transmission supporting wheels 7 are installed in the below, middle part of T font frame 3 respectively by two V-type swing arms 4, the wheel shaft of transmission supporting wheel 7 is installed in the bottom of V-shape swing arm 4, one side arm end of V-type swing arm 4 is articulated in the lower front of the vertical pole of T font frame 3 by bearing pin 8, and can be around bearing pin 8 swings; Another side arm is installed on the below, middle part of the vertical pole of T font frame 3 by dark alignment pin 5 of the upper limit or the dark alignment pin 6 of lower limit, have a plurality of pin-and-holes on this side arm.Adjust two positions of the dark alignment pin of limit on the V-type swing arm up and down, can realize lifting, landing and the depth adjustment of two transmission supporting wheels 7.

Transmission mechanism is a chain-drive mechanism, and one on its sprocket wheel is installed in an end of the wheel shaft of transmission supporting wheel 7, and another is by being located in the bottom of kind of box assembly 1, and chain is striden on two sprocket wheels.

The front end of the montant of its T font frame 3 is welded with traction casing, is connected with the hand tractor connecting frame by traction casing; The infall of beam in length and breadth of T font frame 3 is welded with vertical tube, and the hand tractor tail wheel base can be installed, and makes the operator can be sitting in operation on it.

During use, the dark alignment pin 6 of lower limit is inserted in the pin-and-hole of V-type swing arm 4 one side arms below, transmission supporting wheel 7 is promoted, plough 9 buries, and transmission supporting wheel 7 drives chain drive 2, makes sower begin operation.On move the dark alignment pin 5 of the upper limit in pin-and-hole topmost, make 7 landing of transmission supporting wheel, plough 9 liftoff rises make sower be in travel position.

Claims
