Description

The drum-type chaffcutter

Technical field

The utility model relates to a kind of hay cutter, particularly a kind of drum-type chaffcutter.

Background technology

Along with the continual renovation of edible mushroom technology, utilize straw, weeds to replace timber resources in short supply to become a kind of trend as the culturing raw material of edible mushroom, therefore various cracker and the cutting machines that are used for cutting straw, weeds continue to bring out.For example the patent No. provides a kind of improvement type cutter for cutting material for culture of fungi for 2004200990624 Chinese patent, it is made up of frame, upper casing, lower casing, spout, discharging opening, main shaft, fly cutter rotating disc, fan blade, fly cutter, variable transmission mechanism etc., the fly cutter rotating disc is contained on the main shaft, fly cutter and fan blade are contained on the rotating disc, be provided with the dead knife that cuts with the fly cutter corresponding matching in the spout, the spout place also is provided with a pair of dentation knurled wheel that the force feed material is used.This cutting machine can cut straw, weeds etc., but its structure still has the following disadvantages: (1) a pair of knurled wheel is installed on the movable axis bearing, and the movable axis bearing is connected with frame by the lifting stage clip, the knurled wheel activity space is little, knurled wheel binder mouth position is influenced by spring force and has deviation, and spring has the effect that necessarily obstructs for the lifting of knurled wheel, and the balance in the time of therefore can causing charging is bad, and is easy to generate skew when installing.(2) it is not enough to be used for driving chain drive tensile force when work of dentation knurled wheel work, and chain comes off easily.(3) the machine consumption of power is big, and job stability is low.

The utility model content

The purpose of this utility model is to provide a kind of drum-type chaffcutter, balance when it not only can improve charging, reduce the skew that produces when installing, and help regulating pressure between the lower compression roller, make between chain and the sprocket wheel and keep tensioning state, thereby prevent that chain from taking off chain, guarantee the good stability of complete machine work.

Technical solutions of the utility model are to constitute like this, it comprises frame, be located at the spout of frame front, be located at the frame rear portion discharging opening, be articulated in the main shaft of central rack, by the cutterhead of main shaft driven rotary, be fixedly connected on fly cutter and fan blade on the cutterhead, a pair of the last lower compression roller that is mounted to rightabout force feed material of being located at the spout inboard, be located at the lower compression roller outlet side be used for cooperate the dead knife that cuts with fly cutter and be used for driving main shaft and power set and drive disk assembly thereof that pressure roller rotates; It is characterized in that: the rotating shaft of described lower compression roller directly is articulated on the frame, and the rotating shaft of last pressure roller is connected with frame by rocking arm; Power set drive upward by chain drive, and lower compression roller becomes backward rotation, be used for driving in the chain drive road that pressure roller rotates and be provided with tightener sprocket, the rotating shaft of tightener sprocket is connected with frame by the tensioning rocking arm, also is connected with between the rotating shaft of tightener sprocket and the frame to be used to make the tensioning spring that keeps tensioning state between chain and the sprocket wheel, goes up the suitable pressure of maintenance between the lower compression roller.

During work, power set drive to be gone up lower compression roller by chain drive and are become forward and reverse rotation, and compacting such as the straw that spout is sent into, weeds is also sent into the frame inner chamber; And power set also drive main axis rotation by drive disk assembly simultaneously, main shaft drives the cutterhead rotation, then drive the rotation of fly cutter and fan blade, when fly cutter rotates to the position that cooperates shearing with dead knife, straw or the weeds of delivering to this place are cut, by fan blade the straw or the weeds of well cutting are delivered to discharging opening subsequently.

Than prior art, the utility model is owing to connect upward pressure roller by rocking arm, lower compression roller directly is articulated on the frame, but make and go up pressure roller and rocking arm synchronization lifting, the activity space of last pressure roller is big, therefore binder open height invariant position between the upper and lower pressure roller can keep feed pressure even.In addition, owing to go up the thrust of lower compression roller and the tensile force between chain and the sprocket wheel by tightener sprocket and tensioning spring adjusting, balance when therefore not only helping improving charging, and can reduce the skew that produces when installing, help regulating the suitable pressure between the lower compression roller, make between chain and the sprocket wheel to keep tensioning state, thereby prevent that chain from taking off chain, guarantee the good stability of complete machine work.

Inertia when rotating in order to increase main shaft, the consumption that alleviates machine power, an end of described main shaft is connected transmission by belt or chain drive with power set, and the other end of main shaft is provided with the power-assisted flywheel.

In order further to regulate the stability of running part, the employing self-aligning bearing is connected between each rotating axle and its rotating connecting part.
