Technical Field
The invention relates to the field of agricultural production environment-friendly mechanical equipment, in particular to a self-adjusting transmission system for a straw powder cutting machine.
Background
In the traditional agricultural field, the residual straws after the crops are harvested are generally converted into usable heat energy through burning, for example, cooking is carried out on a rural soil stove, and the residual straws are directly burned in the field. The straw burning pollution generates a large amount of inhalable particles, sulfur dioxide and nitrogen dioxide, pollutes the air environment and is harmful to human health. The field of agricultural environmental protection mainly utilizes straws as biogas sources of biogas digesters or straws are made into livestock feed. The above applications require long straws to be crushed into straw powder for effective utilization.
The long straws are generally crushed by a straw crusher, and the longitudinally arranged straw crusher has the problems of inconvenient material discharge from the top and accumulation and inconvenient split charging caused by too fast material discharge at the bottom due to gravity; the transverse straw crusher has the problem that the straws cannot be effectively and completely crushed after being thrown due to the winding action of the rotary cutter. It is necessary to perform the chopping by pre-compacting the fed straw to solve the above problems. Under the condition that the volume of the fed straws is different, the straws can be stuck when the amount of the straws is large or can not be pre-compacted when the amount of the straws is small.
In summary, the invention aims to solve the problem of how to produce a transmission system which is applied to a straw powder cutting machine, can pre-compact feeding straws and can perform self-adjustment according to the feeding amount of the straws.

The driving system drives the input system to convey the straws placed on the surface of the input system into the pre-pressing assembly for pre-pressing, the rotary tool rest driven by the main motor performs the chopping operation, and the crushed straws are conveyed out and subpackaged through the output system after being chopped. The pre-pressing assembly transmits the rotation of the lower pressing roller driven by the driving system to the adjusting chain wheel and the input driving roller through the transmission of the tensioning chain, and the input driving roller drives the input belt to transport straws and the pre-pressing assembly to pre-press the straws at one time. The upper compression roller is arranged on the outer side of the tensioning chain, and drives the lower compression roller and the upper compression roller to rotate in opposite directions when the tensioning chain moves, so that straws fed in by the input belt are compacted under the extrusion effect of relative rotation. When the straws pass through the upper and lower compression rollers, the straws are pressed to generate relative reaction force, and the reaction force acts on the upper compression roller to jack the straws. Through setting up second damping device produces the downward damping force that acts on go up the compression roller, make it have extra decurrent pressure except self gravity, strengthen the effect that compresses tightly, will simultaneously when the straw quantity is less go up the compression roller and push down and guarantee all compressing tightly the straw under the condition of various straw feeding volumes. When the number of straws is large, the jacking stroke of the upper compression roller is large, so that the tensioning chain is not pressed and loses the tensioning state, and serious problems such as chain loosening, transmission failure and the like can be caused. The cooperation of the first damping device and the second damping device enables the pre-pressing assembly to always keep a proper pre-pressing working state. The effectiveness of the straw pre-compression work is ensured, so that the powder cutting effect of the straw powder cutting machine is improved.

Preferably, the input belt assembly includes an input belt driven roller parallel to the input belt powered roller, and an input belt tensioned between the input belt powered roller and the input belt driven roller.
The input driving roller drives the input belt driven roller to rotate through the tensioned input belt to form a revolute pair which drives the input belt to move continuously, and the function of sending the straws into the pre-pressing assembly is achieved.
Preferably, the output system is arranged at the rear side of the input system and comprises an output driving roller and an output belt driven roller which are arranged in parallel, and an output belt tensioned on the output driving roller and the output belt driven roller.
The output belt power roller drives the output belt driven roller to rotate through the tensioned output belt to form a revolute pair which drives the output belt to continuously move, and the effect of sending the crushed straw out of the straw powder cutting machine is achieved.
Preferably, the driving system comprises a material conveying motor and a speed reducer driven by the material conveying motor.
The material conveying motor can amplify output torque after being decelerated by the speed reducer, so that the material conveying motor can drive the input system and the output system simultaneously, the rotation of the speed reducer is transmitted to the lower pressing roller and the output driving roller, and the lower pressing roller drives the input driving roller. The same conveying motor is used for providing power for the whole conveying process, on one hand, the composition of a mechanism can be driven, and the cost is saved; on the other hand, the output driving roller, the lower pressing roller and the input driving roller can be controlled to move at the same speed, so that the input speed and the output speed of the straws are ensured to be constant and controllable, and the conditions of accumulation, blockage and the like are not easy to occur.
Preferably, the speed reducer is connected with the lower press roll and the output belt power roll chain.
The chain transmission is accurate, the transmission torque is big, and difficult skidding, preferably adopt the chain to connect the speed reducer with input, output power roller makes output drive roller, bottom roll and input drive roller can be with the velocity of speed motion assurance straw input, output speed invariable controllable, difficult emergence is piled up, the condition such as jam.
Preferably, the turret is disposed behind the input system and above the output system.
The rotary knife rest is used for cutting compacted straws, the rotary knife rest is arranged on the rear side of the input system and above the output system, the straws are pulverized and cut after leaving the input system, and the pulverized and cut straw powder falls on the output system below and is sent out of the straw pulverizing machine by the output system for subpackage use.
Preferably, the main motor is connected with the turret belt.
The cutting of the compacted straw requires a large torque to provide sufficient shearing force, so the main motor alone is used to drive the turret to move. But simultaneously, in order to prevent the straws from being wound or the straws are mixed with hard objects such as stones, the rotating tool rest is required to have an overload protection function, so that the belt is adopted to connect the main motor and the rotating tool rest, when the rotating tool rest is overloaded due to winding or cutting failure, the belt slips and does not output the torque of the main motor any more, the main motor is protected from being burnt out, and the rotating tool rest is protected from being damaged.
