Detailed ways

As shown in Figures 1-2, the utility model includes a frame 11, and a crushing device arranged on the frame 11 and used for crushing fallen leaves;

The crushing device is located below the outlet at the right end of the feeding channel 2.

The crushing device comprises a fixed cutterhead 6 fixedly arranged on the frame 11, a rotary motor 7 arranged on the frame, and a rotary cutterhead 4 positioned above the fixed cutterhead 6 and driven to rotate by the rotary motor 7, distributed among the rotary cutterheads. The rotary knife rest 14 on the disc 4, the fixed knife rest 15 arranged on the fixed cutter head 6, and the lower feeding channel 16 arranged on the fixed cutter head 6 for passing the crushed fallen leaves;

The lower end cutting edge of the rotary knife rest 14 performs the rotary motion of shearing/extruding and crushing fallen leaves relative to the upper end cutting edge of the fixed knife rest 15. To realize the cutting and crushing of leaves, as deformation, as long as the fixed cutterhead 6 and the rotating cutterhead 4 rotate at different speeds, the crushing can be realized, which is also the scope of protection of the present utility model.

On the output shaft of the rotary motor 7, the key is connected with an axle sleeve, the rotary cutter head 4 is an annular structure, and the rotary cutter rest 14 is arranged between the inner wall of the rotary cutter head 4 and the outer wall of the axle sleeve. The channel gap is large, which not only ensures the convenience of falling leaves transportation, prevents clogging, but also realizes uniform and efficient crushing.

Pulverizing teeth 17 are arranged at the upper cutting edge of the fixed knife rest 15 and/or the lower cutting edge of the rotating knife rest 14 . Thereby improving the crushing efficiency and crushing quality.

The fixed knife rest 15 is a multi-circle concentric circular saw blade and a connecting frame arranged between adjacent circular saw blades, and the lowering channel 16 is a gap between adjacent circular saw blades. Thereby it is convenient for the leaves to fall into the powder collection box after being crushed. Through the concentric ring structure, the crushing efficiency and crushing quality can be improved.

The rotating speed of the rotating motor of the pulverizing device can be set according to the size of the amount of leaves and the degree of dryness and wetness.

Elastic leaf-pushing fingers 13 obliquely distributed on the rotating knife rest 14 to push fallen leaves obliquely downwards or elastic leaf-pushing fingers 13 are obliquely distributed on the fixed knife rest 15 .

The elastic blade finger 13 is a stainless steel spring steel wire. The upper end of the spring steel wire has a radian to realize the downward pressure on the leaves during the rotation, and the lower end of the spring steel wire goes deep into the falling and dropping channel 16 between the saw blades of the fixed cutter head to realize the power demand of the leaf crushing process.

The frame 11 is provided with a dust removal cover 5 covering the outside of the crushing device, so as to realize the isolation of leaf dust and avoid causing air dust pollution.

The specific working principle of the crushing device is

After the leaves enter the crushing device from the feeding channel 2, the crushing process begins. The leaves start to rotate under the drive of the rotary cutter head 4. During the rotation, the leaves are still under the action of the sawtooth on the fixed cutter head 6, that is, the crushing teeth 17. Friction cutting, the leaf powder after friction cutting falls in the powder material collection box 9 under the effect of gravity, in this process realized the rapid pulverization to leaf. The stainless steel spring steel wire on the rotary cutter head has a certain angle, which can make the leaves generate a downward force during the rotation of the rotary cutter head, so that the leaves are quickly cut by the sawtooth and the crushing efficiency is improved. The stainless steel spring steel wire of elastic leaf pulling finger 13 has certain elasticity, and when the amount of leaves is too large or blocks up the fixed cutterhead, the rotating motor can be protected from being stuck.

The left end of the frame 11 is provided with a leaf collection hoist wheel 1 driven by a motor to rotate and be involved in fallen leaves, and the left lower end entrance of the feeding channel 2 is arranged on the right side of the leaf collection hoist wheel 1; below.

As preferably, the leaves collection hoisting wheel 1 is positioned at the front end of the whole traveling device, and the crushing device is positioned above the frame and is covered by a dust removal cover.

The rotating speed of leaf collection hoist wheel 1 can be adjusted according to the size of fallen leaves, and after the speed is adjusted, the motor of leaf collection hoist wheel 1 can automatically adjust the torque according to the amount of leaves to cope with the workload.

A powder collection box 9 for storing broken leaves is arranged below the crushing device. To realize the powder collection function after the leaves are pulverized, an opening baffle plate can be movable below the powder collection box 9, and the powder collected can also fertilize green vegetation such as flowers and plants in situ from this opening.

A walking device is provided at the bottom of the frame 11; the running device includes a front traveling wheel 3 positioned at the left side of the frame 11, a rear traveling power wheel 8 positioned at the right side of the frame 11, a motor which is arranged on the frame 11 and is used to provide electric energy. Storage battery 12, and the handrail 10 that is arranged on the right side of frame 11.

The walking device is powered, and the walking speed can be set according to the walking speed of the operator and the amount of fallen leaves.

Power is supplied to the motor by the accumulator 12, thereby driving the rear walking power wheel 8 to rotate and walk, realizing the self-propelled function of the leaf collection pulverizer.

Power is supplied to the motor through the battery 12, and the motor drives the leaf collection hoist wheel 1 to rotate and be involved in fallen leaves, and the leaves are rolled up and sent to the feeding channel; The claws or teeth are used to roll in the fallen leaves through the claws or teeth to realize feeding.

The feeding channel 2 is a common structure such as a common belt drive or a chain drive, which realizes the function of the channel where the fallen leaves are rolled up by the hoist and enter the crushing device.

The utility model is reasonable in design, low in cost, strong and durable, safe and reliable, simple in operation, saves time and effort, saves money, has compact structure and is convenient to use.

The full description of the utility model is for a clearer disclosure, and the prior art will not be given as examples one by one.
