Description

Horizontal straw crushing and returning machine

The utility model relates to a corn stalk crushing device, in particular to a horizontal straw crushing and returning machine.

my country has a large area of corn planting and produces a lot of straw. Many farmers rush to sow seeds to save trouble. Most of the straw is abandoned or burned. Therefore, the content of organic matter in the soil in our country is decreasing year by year. On the other hand, a large amount of Straw disposal not only causes waste, but also pollutes the environment. Mechanized straw returning is the most effective and fastest way to develop ecological agriculture, reduce environmental pollution, improve soil fertility, increase soil organic matter content, increase crop yield, and solve straw burning and waste.

With the acceleration of mechanized straw returning, various straw returning machines have appeared all over the country. From the point of view of the connection mode of the corn straw returning machine, there are three-point rear-mounted horizontal shaft type on the tractor, front-mounted vertical shaft type, and front-mounted type for the combine harvester. Its main working parts are: straight knife type, hammer claw type, L type, Y type, T type, and its operation mode is unsupported cutting, which consumes a lot of power. According to the research, the hammer-claw type, L-type, and Y-type knives have good pick-up effect, but poor chopping performance; That is to say, the existing models have high power consumption with good crushing effect, and poor effect with low power consumption. Moreover, the tool life used is short.

The purpose of the utility model is to provide a horizontal corn stalk grinder with good crushing effect and low power consumption.

The purpose of this utility model is achieved in this way: the utility model includes a casing, a rotor, a fixed knife, a gear box, etc., and two front and rear rotors are arranged in the casing, and the front rotor is provided with a pick-up claw, and the pick-up claw and the front rotor The movable connection of the fixed shaft is adopted, a straight knife is arranged on the rear rotor, and a fixed knife is arranged on the casing corresponding to the straight knife.

The straight knife and the rear rotor of the utility model can be movably connected by a fixed shaft.

The claw tooth of the utility model picks up claw and the blade of straight knife adopts radial intersect setting.

The rear rotor shaft of the utility model is arranged higher than the front rotor shaft.

The utility model adopts the setting that the rotating speed of the front rotor is lower than that of the rear rotor.

The utility model installs two crushing rotors in one casing, the front rotor is equipped with pick-up claws for picking up, and the rear rotor is equipped with straight knives for crushing. The blowing, cutting, bumping, rubbing, tearing and other methods of the knife smash and spread to the ground surface.

The front rotor of the utility model has a low rotating speed and only plays the role of picking up, and the power consumption is small, which also increases the durability of the cutter. The effect of this model on crushing straw once in the field has reached or exceeded the effect of other models crushing twice, and it reduces power consumption, which provides the possibility of widening the range for models with the same power.

The structure provided by the utility model can be used no matter in the rear suspension model of the tractor or the front model of the combine harvester.

The utility model will be described in detail below in conjunction with accompanying drawing:

Accompanying drawing 1 is the structural representation of the utility model.

Accompanying drawing 2 is a side sectional view of the utility model.

Accompanying drawing 3 is the supporting use structure schematic diagram of the utility model and harvester.

Accompanying drawing 4,5 is the fixed knife structure schematic diagram.

Accompanying drawing 6, 7 is the schematic diagram of picking up claw Y-shaped structure.

In the attached drawings: 1 casing, 2 front rotor, 3 rear rotor, 4 fixed knife, 5 pick-up claw, 6 straight knife, 7 active sheave, 8 front rotor passive sheave, 9 front rotor active sheave, 10 rear Rotor passive sheave, 11 gear box, 12 suspension frame, 13 left belt cover, 14 right belt cover, 15 bearing seat, 16 support roller, 17 Y-shaped pick-up claw, 18 fixed shaft, 19 front rotor shaft, 20 rear rotor shaft , 21 fixed shafts, 22 claws.

The utility model includes a casing 1, a front rotor 2, a rear rotor 3, multiple rows of fixed knives 4, picking claws 5, straight knives 6, transmission sheaves 7, 8, 9, 10, gear boxes 11, suspension frames 12, belts Covers 13, 14, bearing housing 15, support roller 16, etc.

In the utility model, two crushing rotors are installed in a casing 1, and the front rotor 2 is equipped with picking claws 5 (or L-shaped knife, Y-shaped knife 17) to play a role of picking up, plus the negative pressure generated by the rotation of the rotors, the straw Preliminary crushing and feeding into the casing 1, the rear rotor 3 is equipped with a straight knife for crushing, the straw fed by the front rotor 2 passes through the high-speed straight knife 6 and the fixed knife 4 (installed in the casing 1) The chopping, cutting, bumping, rubbing, tearing and other methods are crushed and spread to the ground surface.

The front rotor 2 of the utility model has a low rotating speed and only plays the role of picking up. The power consumption is small, and the durability of the cutter is also increased. The rear rotor 3 has a high rotating speed, does not break the soil, and only crushes straw, and the power used is not large. The effect of this model on straw crushing once in the field has reached or exceeded the effect of other models crushing twice, and it reduces power consumption, which provides the possibility of widening the width for models with the same power.

The belt pulley 9,10 that the utility model is driven by the front rotor 2 to the rear rotor 3 is installed on the other side of the pulverizer, which solves the balance problem of the complete machine.
