Abstract

The utility model discloses a special wheel for sowers, which comprises a wheel rim and an auxiliary wheel which are coaxial to each other and are connected with each other to form an integrative structure, the diameter of the wheel rim is relatively large, the auxiliary wheel is in a conical shape, the diameter of a big head of the auxiliary wheel is equal to the diameter of the wheel rim, a plurality of wheel nails are uniformly distributed on the wheel rim and the auxiliary wheel, and the inner side of the auxiliary wheel is provided with a tilling blade. When the special wheel for sowers is installed on the sower, the wheelbase of the sower can be reduced while center of gravity of the sower is not raised; thus, the sower can easily work in the narrow interspaces of the crops of a farmland; simultaneously, the wheel nails can cause the friction force between the wheel and the ground to be increased, and the tilling blade can smash clay and weed which are adhesively bonded on the wheel; thereby, stabler walking operation of the sower can be realized.

Description

The special-purpose wheel of a kind of sower

The utility model relates to a kind of accessory of seeding machinery, the special-purpose wheel of particularly a kind of sower.

Field interplanting can improve the degree of utilization in soil, saves the spending of agriculture chemical, but the sowing the during interplanting of field wastes time and energy, and general sower is because the body broad rolls down crops easily during sowing; The tire of common wheel is too wide, is not suitable for sower and uses, and narrower tire is absorbed in the soft earth again easily; In addition, traditional tire no matter be wide tire or narrow tire, overturns when running into native a clod of earth easily, and earth and weeds also are stained with in walking easily in wetability earth, and earth and weeds are stained with more and more, must influence walking and farming.

The purpose of this utility model provides the special-purpose wheel of a kind of sower that a kind of suitable sower uses.

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

The special-purpose wheel of a kind of sower described in the utility model comprises wheel rim, and the inboard of wheel rim has the taper jockey pulley coaxial with it, and the inboard of jockey pulley has rotary blade.

In order to increase when walking and ground-surface friction force, on the circumference of wheel rim and jockey pulley, be evenly distributed with cylindrical wheel and follow closely.

After adopting technique scheme, the special-purpose wheel of a kind of sower described in the utility model comprises wheel rim and the jockey pulley that is fixed together, the wheel rim relative narrower, to reduce the wheelspan of sower, and jockey pulley is conical, can be installed in wheel rim inboard sower change speed gear box below, because during the interplanting of field, the shape on ridge be exactly in the middle of at the bottom of the high both sides, the special-purpose wheel positive sign of this sower that is installed in the sower both sides has adapted to this shape, so promptly can be and do not increase wheel and ground-surface effective area of contact under the prerequisite of extension rim distance, the stability that the raising sower travels in the center of gravity that does not improve sower; Wheel nail on the wheel rim can increase and ground-surface friction force, and the rotary blade of wheel inboard can be smashed the earth and the weeds that stick on the wheel, get rid of, and gets rid of advancing obstacle.Indulge the above, the stability when the special-purpose wheel of a kind of sower described in the utility model can improve sower work is particularly suitable for using at the sower of wetability field, soil interplanting operation.

Further specify the utility model below in conjunction with drawings and Examples:

Fig. 1 is the front view of an embodiment of the present utility model;

Fig. 2 is the left view of Fig. 1.

As shown in Figure 1 and Figure 2, the wheel rim 1 of the special-purpose wheel of the said a kind of sower of the utility model is narrower, rectangular distribution 14-30 only takes turns nail 3 on the method for the circumference employing welding of wheel rim 1, the diameter at butt end of cylindrical-conical jockey pulley 2 equals the diameter of wheel rim 1, and be welded on the inboard of wheel rim 1, and coaxial with wheel rim 1, be welded with wheel nail 3 on the jockey pulley 2 equally; Have rotary tillage knife rest 5 in the inboard of jockey pulley 2, rotary blade 4 is installed on the rotary tillage knife rest 5, rotary blade 4 can be selected the rotary blade on the common rotovator for use, also can use special cutter.

The special-purpose wheel of a kind of sower in the present embodiment is formed by metal solder fully, and wherein wheel rim 1 also can adopt narrower rubber wheel, so that travel on prevailing roadway.
