Description

Rigging cutter shaft assembly

technical field

The utility model relates to agricultural machinery, in particular to a ridge cutter shaft assembly.

Background technique

Among the existing agricultural machinery, there is a rotary tiller ridging machine, on which the rotary tiller ridging knife shaft assembly is shown in Figure 1, which consists of a rotating shaft 2 and ridging knives 1 evenly distributed on the surface of the rotating shaft 2. The ridge cutters 1 are evenly distributed on the entire rotating shaft 2. Such a design will disperse the land, especially in the ridges that have been rotary plowed, and scatter the pre-applied base fertilizer, reducing the fertilizer efficiency of the land.

Utility model content

The purpose of the utility model is to overcome the defects of the prior art and provide a ridging cutter shaft assembly that does not disperse the fertilizer applied in advance so as to improve the fertilizer efficiency.

The technical scheme provided by the utility model is as follows: a ridge cutter shaft assembly includes a rotary tillage shaft and a plurality of ridging knives, and the plurality of ridging knives are evenly distributed on the outer circumference of both ends of the rotary tiller shaft , the middle section of the rotary shaft is the optical axis.

As a preference, in the above-mentioned ridging cutter shaft assembly, a plurality of inserting seats are provided on the outer circumferences of both ends of the rotary tiller shaft, and the ends of the ridging cutters are inserted into the inserting seats. There are bolts for locking the ridging knife.

Preferably, in the above-mentioned ridging cutter shaft assembly, four ridging knives are respectively installed on the outer circumferences of the two ends of the rotary tiller shaft, and the four ridging knives are helically and evenly arranged around the rotary tiller shaft.

The utility model has the following advantages: there is no ridging knife in the middle section of the rotary shaft of the rotary tillage, and when the rotary tillage land is used, it will not be scattered on the land in advance, especially in the middle part of the ridge field that has been rotary tillage. The base fertilizer only breaks up the land next to the base fertilizer, which makes the base fertilizer of the land more concentrated and improves the fertilizer efficiency of the land. It is suitable for the growth of crops such as tobacco, sweet potato, and potato; the rotary tiller and the rotary shaft are connected by inserting sockets and bolts , easy to maintain and replace; four ridging knives are spirally and uniformly arranged around the rotary tillage shaft, and the force is more even, which is beneficial to prolonging the service life.

Detailed ways

Below in conjunction with accompanying drawing, specific embodiment is described:

As shown in Figure 2, a ridging knife shaft assembly includes a rotary tiller shaft 2 and a plurality of ridging knives 1, usually four ridging knives are evenly distributed on the outer circumference of both ends of the rotary tiller shaft 2 1. Of course, the number of ridging knives 1 can also be increased or decreased according to the needs of different soils. Ridging knives 1 are in the shape of a spiral plate in the longitudinal direction and half-moon in the transverse direction; the middle section of the rotary shaft is the optical axis; There is no ridging knife in the middle of the rotary tillage shaft. When the rotary tillage land is used, it will not disperse the basal fertilizer applied on the land in advance, especially in the middle of the ridge field that has been rotatively tilled, and only disperse the basal fertilizer next to it The land makes the base fertilizer of the land more concentrated, improves the fertilizer efficiency of the land, and is suitable for the growth of crops such as tobacco, sweet potato, and potato.

In the above-mentioned rotary tiller shaft assembly, four insertion seats 3 are arranged on the outer circumference of both ends of the rotary tiller shaft 2, and the end of the ridging knife 1 is inserted into the insertion seats 3, and the insertion seats 3 Bolts 4 for locking the ridging knife 1 are provided on the side wall of the ridge; the rotary tiller and the rotary shaft are connected by inserting sockets and bolts, which is convenient for maintenance and replacement. Of course, it can also be connected by pins, rivets, etc. connections, even soldering.

In the above-mentioned ridging knife shaft assembly, four ridging knives 1 are respectively installed on the outer circumference of the two ends of the rotary tillage shaft 2, and the four ridging knives 1 are arranged spirally and uniformly around the rotary tillage shaft 2. The ridging knives 1 are helically and evenly arranged around the rotary tillage shaft 2, so that the force is more even, which is beneficial to prolong the service life.

Of course, the above embodiments are only intended to illustrate rather than limit the utility model, and the above description is only a preferred embodiment of the utility model, so all works according to the structure, features and principles described in the scope of the utility model patent application Equivalent changes or modifications are included in the scope of the utility model patent application.
