Description

Plant straw picking and pulverizing machine

technical field

The utility model relates to an agricultural machine, in particular to a plant straw picking and crushing machine. the

Background technique

The traditional method of harvesting crop stalks or pastures generally includes steps such as cutting down and bundling, and transporting them to home or designated locations for crushing as needed. The labor intensity is high and the degree of mechanization is low. Especially in the autumn harvest season, agricultural labor is in short supply. The cost of harvesting and processing is too high. Many crop stalks cannot be harvested in time and are thrown in the farmland. This not only wastes biomass energy and forage, but also affects the next stubble. Operation. the

In the prior art, plant straw crushing and harvesting machines with multiple functions such as harvesting and crushing are generally large-scale combined harvesting machines with complex structures, large power requirements, and large machine volumes. The cost is high, and it is not suitable for the needs of small-scale rural operations. the

The purpose of this utility model is achieved in this way: a plant straw picking grinder, characterized in that it includes a power transmission system, a crushing chamber and a collection chamber that communicate with the upper part of the adjacent surface, the crushing chamber is at the front of the body, and the collection chamber At the rear of the body; the upper part of the crushing chamber is equipped with arc-shaped tooth plates, the lower part of the crushing chamber is an open straw feeding inlet, and the crushing roller is set in the crushing chamber, and several hinges that can extend out of the straw feeding inlet are hinged on the rollers. Pick up and crush the scimitar; a screw feeder is set in the collection room, and a lifting feeding fan driven by the same feeding shaft as the screw feeder is set on one side of the collection room; supporting rollers are set on the body at the rear of the collection room; the power transmission system It includes a bevel gearbox connected to the traction main engine at the front of the body. The bevel gearbox leads out a main drive shaft laterally. The main drive shaft drives the crushing roller to rotate through the pulley and the belt, and the other end of the crushing roller passes through the pulley and the belt. Drive the feed shaft to rotate. the

In order to facilitate inspection and cleaning of straw debris in the collection chamber, an openable collection chamber upper cover is provided on the upper part of the collection chamber. the

In order to prevent the plant stalks from splashing to the front during the picking and crushing process, several baffles are hinged on the body at the front of the stalk feeding inlet. the

In order to prevent the belt drive from losing rotation, a belt pressing mechanism is arranged on the transmission belt between the crushing roller and the feeding shaft. the

Compared with the prior art, the utility model has the advantages that: the utility model has a simple structure and a compact body, and can be hung on the rear of the tractor as a whole, and the power output shaft at the tail of the tractor drives the straw of the plant through the universal transmission shaft to pick up and pulverize Machine work, no need to configure additional power, low production cost, suitable for small-scale farmland operations and small-scale rural operations, simple operation, flexible and convenient operation. The lower part of the crushing chamber is an open straw feeding inlet, and a fixed crushing roller is set in the crushing chamber, and a number of picking and crushing scimitars that can extend out of the straw feeding inlet are hinged on the rollers. The cut down plant stalks are picked up and cut into pieces and sent to the collection room, and the standing plant stalks can be harvested and crushed and sent to the collection room. The crushed straw is collected in the transport vehicle, which can realize the combined operation of picking, crushing and conveying, and has high work efficiency. the
