Description

Straw chopper

Technical Field

The utility model belongs to the technical field of chopper, in particular to a straw chopper.

Background

China is a big agricultural country, and the crop straw stock is very large. The straw can be used for traditional paper making and feed processing, and can also be used as a biomass energy source, namely straw returning. When the straw is utilized, the problem of how to rapidly decompose the straw is firstly solved.

The straw is usually the residual part of wheat, rice, cotton, corn and other crops after being harvested, and the straw is used as a byproduct of agricultural production, has large yield and wide distribution, and is also an important biological resource. About half of the products of crop photosynthesis exist in straws, and are a renewable material resource with multiple purposes.

The straws are also agricultural products, and account for about 50% of the total biomass of the agriculture, but the traditional straw treatment mode is to enable the straws to naturally weather, rot and burn. The northern climate is dry, and the straw is difficult to decompose by natural weathering. The ground temperature of the on-site straw burning reaches about 300T, and the loss of water, nitrogen, phosphorus, carbon, direct bacteria and bacteria in the soil is serious; destroying a certain ecological balance.

The straw is not allowed to become a resource with misplaced positions. The problem that the straw is smashed and returned to the field and quickly decomposed and returned to the field becomes a research subject at present.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a stable in structure, smash effectual, long service life's straw chopper.

The purpose of the utility model is realized like this: the utility model provides a straw chopper, includes the chopper body, the chopper body includes the support, sets up tire, the push rod of setting on the support and the engine of setting in support up end one side in the support both sides, the pot head is equipped with first belt pulley and second belt pulley under the engine, first belt pulley one end is connected with through first belt and is used for driving tire pivoted third belt pulley, second belt pulley one end is connected with the fourth belt pulley through the second belt, wear to be equipped with the axis of rotation in the fourth belt pulley, the cover is equipped with the gear box in the axis of rotation, the pot head is equipped with the cutting knife under the axis of rotation, the axis of rotation includes first installation pole and second installation pole, angle between first installation pole and the second installation pole is alpha.

Preferably, the angle α between the first and second mounting rods is between 100 and 170 degrees.

Preferably, one end of the bottom of the support is provided with a universal wheel which is convenient for the cutting machine to steer.

Preferably, one end of the bracket is provided with a protective cover.

Preferably, the push rod is provided with an operating mechanism.

Compared with the prior art, the utility model outstanding and profitable technological effect is: the utility model discloses a chopper can form certain contained angle with ground in the rotation plane of cutting knife when using. The straws can be repeatedly flapped and crushed in the advancing process to form fine powder and fragments. This way the shredding efficiency is very high.

FIG. 1 is one of the schematic structural diagrams of the present invention;

FIG. 2 is one of the schematic structural diagrams of the present invention;

fig. 3 is a side view of the present invention;

fig. 4 is a diagram of the shredding effect of the present invention.

Detailed Description

The invention will be further described with reference to specific embodiments.

As shown in fig. 1-3, a straw chopper comprises a chopper body 1, wherein the chopper body 1 comprises a bracket 2, tires 3 arranged at two sides of the bracket 2, a push rod 4 arranged on the bracket 2 and an engine 5 arranged at one side of the upper end surface of the bracket 2, a first belt pulley 6 and a second belt pulley 7 are sleeved at the lower end of the engine 5, one end of the first belt pulley 6 is connected with a third belt pulley 9 used for driving the tire 3 to rotate through a first belt 8, one end of the second belt pulley 7 is connected with a fourth belt pulley 11 through a second belt 10, a rotating shaft 12 is arranged in the fourth belt pulley 11 in a penetrating way, a gear box 13 is sleeved on the rotating shaft 12, a cutting knife 14 is sleeved at the lower end of the rotating shaft 12, the rotating shaft 12 comprises a first mounting rod 15 and a second mounting rod 16, and the angle between the first mounting rod 15 and the second mounting rod 16 is alpha.

The angle between the first mounting rod 15 and the second mounting rod 16 of the shredder of the technical scheme can be set to enable the cutting knife to incline so as to increase the cutting efficiency and the shredding effect.

Preferably, the angle α between the first mounting rod 15 and the second mounting rod 16 is between 100 and 170 degrees.

Preferably, the bottom end of the support frame 2 is provided with a universal wheel 17 for facilitating the steering of the shredder. The provision of the universal wheel 17 facilitates steering of the shredder during use.

Preferably, the bracket 2 is provided with a protective cover 18 at one end. The arrangement of the protective cover 18 can enable debris to splash to people on the side when the straw is cut, and the safety performance of the straw cutting machine is improved.

Preferably, the push rod 4 is provided with an operating mechanism 19. The provision of the operating mechanism 19 on the push rod 4 allows the user to control the shredder, including advancing, retracting and braking.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
