Description

Device for preventing rotary cultivator cutter shaft from winding grass

Technical Field

The utility model relates to the technical field of agricultural machinery parts, in particular to a device for preventing grass from being wound on a rotary tiller shaft.

Background

The rotary cultivator is a common tillage implement in China, integrates tillage and harrowing, and can achieve the working effect of plowing and harrowing cattle for several times by one-time rotary tillage operation of farmlands. The shaft of a rotary tiller is one of the most important parts of the rotary tiller. A cutter shaft of the rotary cultivator is arranged on a frame of the rotary cultivator through a short shaft and a bearing seat, a rotary cultivator cutter is arranged on the cutter shaft through a cutter holder, and the cutter holders are symmetrically arranged on the cutter shaft in a cross shape.

The rotary cultivator can cause the phenomenon that a rotary cultivation cutter shaft is wound with grass when in use, and the rotary cultivator is usually stopped for cleaning after being used for half a day, so that the work is seriously influenced. The existing integrated agricultural machine is mainly composed of a rotary tillage cutter shaft and a cutter, blades are designed to be straight plates or wedge-shaped blades, and due to the fact that the angle between the blades on the cutter shaft is not suitable, the blades cannot well shred straws, the blades are easy to wind, the rotary tillage effect is poor, the soil covering rate of seeds is poor, after the cutter shaft winds grass, the working resistance is increased, the seeds need to be cleaned frequently, and the production efficiency is difficult to improve.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a prevent that rotary cultivator arbor from twining careless device to the rotary cultivator arbor who provides easily twines careless in solving above-mentioned background art, and then leads to the relatively poor problem of earthing rate of seed.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a prevent that rotary cultivator arbor from twining careless device, includes arbor seam piece, except that grass board, right blade, left bearing frame, blade holder, right bearing frame, drive gear, its characterized in that: the cutter shaft is composed of the cutter shaft welding piece, the weeding plate, the right blade, the left blade and the cutter holder, the front end of the cutter shaft penetrates through the right bearing seat to be fixedly connected with the transmission gear, and the rear end of the cutter shaft is fixedly provided with the left bearing seat.

Preferably, a plurality of tool holders are spirally distributed on the cutter shaft, and blades are arranged on the tool holders.

Preferably, the blades are divided into a right blade and a left blade, the bent parts of the first blades of the two adjacent blades extend out to the front side to form the left blade, the bent parts of the second blades extend out to the back side to form the right blade, and the right blade and the left blade are arranged at intervals in a spiral manner.

Preferably, four grass eradication plates are arranged on the cutter shaft and are uniformly arranged on the circumference of the cutter shaft.

Compared with the prior art, the beneficial effects of the utility model are that:

1. four weeding boards that the device set up are evenly arranged on the arbor, make in the careless unable entering arbor of stretching into of arbor, have effectively prevented that the arbor operation in-process from being twined by the grass.

2. The device sets up right blade, left blade at the operation in-process, has increased the cutting plane, effectively cuts up weeds.

3. The device structure is rigorous, and reasonable in design has guaranteed that rotary cultivator during operation has effectively avoided the winding of debris such as weeds, earth, improves work efficiency, is fit for using widely.

Drawings

FIG. 1 is a schematic perspective view of a device for preventing grass winding on a rotary tiller shaft according to the present invention;

FIG. 2 is a schematic view of a partial enlarged structure at the position A of the grass winding prevention device for the rotary tiller shaft of the present invention;

as shown in fig. 1-2, the various parts of the figure are represented by the following arabic numerals:

a cutter shaft welding part-1, a weeding plate-2, a right blade-3, a left blade-4, a left bearing seat-5, a cutter seat-6, a right bearing seat-7 and a transmission gear-8.

The invention will be described in more detail with reference to the following examples and the accompanying drawings:

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a device for preventing grass from winding on a rotary cultivator cutter shaft comprises a cutter shaft welding piece 1, a weeding plate 2, a right blade 3, a left blade 4, a left bearing seat 5, a cutter seat 6, a right bearing seat 7 and a transmission gear 8.

The combined type weeding cutter shaft is characterized in that the cutter shaft welding piece 1, the weeding plate 2, the right blade 3, the left blade 4 and the cutter holder 6 are combined into a cutter shaft, the front end of the cutter shaft penetrates through a right bearing seat 7 to be fixedly connected with a transmission gear 8, and a left bearing seat 5 is fixedly arranged at the rear end of the cutter shaft.

The cutter shaft is spirally provided with a plurality of cutter holders 6, and the cutter holders 6 are provided with blades.

The blade is divided into a right blade 3 and a left blade 4, the bent parts of the first blades of the two adjacent blades extend out to the front side to form the left blade 4, the bent parts of the second blades extend out to the reverse side to form the right blade 3, and the right blade 3 and the left blade 4 are arranged at intervals in a spiral mode.

Four grass eradication plates 2 are arranged on the cutter shaft and are evenly distributed on the circumference of the cutter shaft.

In the use process, the cutter shaft is installed on a rotary cultivator frame through a bearing, the power is output by a tractor, the power is transmitted to the cutter shaft through a gear box and a gear to drive the cutter shaft to rotate, and the blade is divided into a right blade and a left blade to cut soil, stalks and grass. The weeding plate 2 can effectively eliminate the winding of long stalks and grass on the cutter shaft, and the weeding plate 2 can also improve the flatness of the soil after the rotary cultivator is operated.
