Abstract

The utility model discloses an earthing and furrowing cutter for a micro-cultivator, which comprises a furrowing cutter and an earthing cutter, wherein the furrowing cutter connecting shaft of the furrowing cutter is connected with a power shaft, and the furrowing cutter connecting shaft adopts a hexagonal steel pipe and is provided with a through hole; when the furrowing cutter connecting shaft is connected with the power shaft, a positioning shaft passes through the power shaft and the through hole to position and fasten. The utility model has the advantages that: the furrowing cutter connecting shaft in the scheme can adopt a standard hexagonal steel pipe under the delivery condition, and then a round pin passes through the furrowing cutter connecting shaft to position and fix, thereby avoiding the spline processing, so that not only the positioning is accurate, but also the cost is reduced, and the installation is convenient; and the cutter body can not be separated from the power shaft in the course of work, thereby, the connection is reliable.

Description

Mini-size tillage machine ridging ditching knife

Technical field

The utility model relates to the power connection shaft structure of mini-size tillage machine with ditching knife and ridging cutter.

Background technology

Agricultural Miniature cultivator used on higher is called for short mini-size tillage machine, mini-size tillage machine is used for farmland operation, trench digging often carries out simultaneously with ridging during the arable land, use the ridging ditching knife, promptly earth up while ditching, mini-size tillage machine and farming instrument claimed structure thereof are simple, cheap, the ridging ditching knife is made of ditching knife and ridging cutter, normally tool rest is ploughed in staggered welding on connecting axle, plough to install on the tool rest and plough cutter, the connecting plate of form of flanges is set in the end of connecting axle, ditching knife is interconnected to a compound ridging ditching knife with the ridging cutter by connecting plate, with reference to accompanying drawing 1, Fig. 2, welding ditching knife connecting plate 12 on the ditching knife connecting axle 11 of ditching knife 1, welding ridging cutter connecting plate 22 on the ridging cutter connecting axle 21 of ridging cutter 2, ditching knife connecting plate 12 is connected with bolt 3 mutually with ridging cutter connecting plate 22; The common connection with power take-off is chosen in ditching knife connecting axle 11, and ditching knife connecting axle 11 adopts tubular types, and the centre is that splined hole 15 is connected with line shaft, and ridging cutter connecting axle 21 adopts the hole core barrels, and power ditching knife connecting axle 11 drives; Line shaft is designed to the splined shaft form, inserts splined hole 15 backs with ending a screw 6 location and fastening, because the spline form, difficulty of processing is big on the technology, and cost is higher, and it is loosening easily because of vibrating at work to end a screw, make cutter hub break away from line shaft, influence work.

The utility model content

The purpose of this utility model is: provide a kind of mini-size tillage machine with the ridging ditching knife, solve the problem that above-mentioned prior art exists, it is reliable, cheap that the ridging ditching knife is connected.

Mini-size tillage machine of the present utility model ridging ditching knife, comprise ditching knife and ridging cutter, ditching knife connecting axle by ditching knife is connected with line shaft, its ditching knife connecting axle adopts six square steel tubes and through hole is set, when being connected, passing line shaft with alignment pin and position with fastening with this through hole with line shaft.

The utlity model has following advantage: the ditch cutter connecting axle in the scheme can adopt six square steel tubes of the supply of material state of standard, pass with a round pin again and position with fastening, avoided spline processing, and six square steel tubes can directly have been bought, not only accurate positioning also reduces cost, and is also easy for installation, and cutter hub and line shaft are broken away from, thereby connect reliable.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the schematic perspective view of the mini-size tillage machine of prior art with ridging ditching knife structure;

Fig. 2 is the cutaway view of Fig. 1 duty;

Fig. 3 is the schematic perspective view of mini-size tillage machine of the present utility model with ridging ditching knife structure;

Fig. 4 is the cutaway view of Fig. 3 duty.

Embodiment

Referring to accompanying drawing 3, Fig. 4, mini-size tillage machine is by ditching

knife

1 and 2 groups on ridging cutter with the ridging ditching knife and forms, ditching knife 1 is to plough tool rest 14 by staggered welding on the ditching knife connecting axle 11, plough the blade formation is installed on the tool rest 14, the ditching knife connecting plate 12 of the equilateral triangle of one end welded flange form of ditching knife connecting axle 11 has bolt hole on the ditching knife connecting plate 12; Ridging cutter 2 and ditching knife 1 structure are basic identical, are made of ridging cutter connecting axle 21, cultivated tool rest 24, ridging blade, ridging cutter connecting plate 22; Ditching knife 1 is interconnected to a ridging ditching knife with ridging cutter 2 by ditching knife connecting plate 12 and ridging cutter connecting plate 22, connects with three bolts; Be connected by ditching knife connecting axle 11 with line shaft and finish, ditching knife connecting axle 11 adopts six square steel tubes, six square steel tubes are directly selected supply of material state for use, the endoporus 16 of six square steel tubes is used for inserting line shaft, only the line shaft end also need be designed to the hexagon of hole dimension in six square steel tubes, processing also can be simpler than splined shaft, six square steel tubes are also processed a through hole, when being connected with line shaft, pass line shaft with alignment pin 7 and position with fastening with this through hole, alignment pin 7 can adopt the step axle of prior art and split pin to be fixed on the ditching knife connecting axle 11.

Claims

1. a mini-size tillage machine is with the ridging ditching knife, comprise ditching knife and ridging cutter, ditching knife connecting axle by ditching knife is connected with line shaft, it is characterized in that: described ditching knife connecting axle (11) adopts six square steel tubes and through hole is set, when being connected, passing line shaft with alignment pin (7) and position with fastening with this through hole with line shaft.
