Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of municipal gardens, in particular to an automatic pruning device for green belt maintenance. BACKGROUND

[0002] With the development of urbanization and people's attention to the environment, the green area of the city is getting larger and larger, which greatly improves the environment of the city. However, the management task of these green areas is also increasing. In order to maintain the neatness of the city, the green belt of the city needs to be pruned regularly to avoid the arbitrary growth of shrubs in the green belt, which endangers the safety of traffic and affects the neatness of the city.

[0003] The traditional pruning of the green belt mainly uses manual pruning with garden shears or electric saw pruning machines. Since manual pruning is used, the pruning speed is very slow, and many garden workers need to work at the same time, which is high in labor cost and low in work efficiency. The pruning effect is not the same due to the complete reliance on the technology of garden workers, resulting in unattractive pruning. In addition, for some special-shaped green plants such as columnar or spherical shrubs, the angle of the pruning tool needs to be changed during pruning, which is very labor-intensive and tests the technical level of the pruning workers, and the pruning efficiency is even lower. Therefore, people have proposed a pruning device, such as the municipal green belt pruning device disclosed in Chinese patent CN107439239A, which comprises a vehicle body and a rotating frame. The bottom of the rotating frame is fixedly connected with a horizontal rod. The present application is provided with a horizontally rotating rod and a vertically rotating rod, so that the cutting wheel and the auxiliary cutting wheel can present a certain arrangement angle in space, and different shapes of green belts can be pruned, which has good adaptability and greatly improves the pruning efficiency and effect of the municipal green belt.

[0004] However, in actual use, a large amount of fallen leaves and branches will be generated after the pruning device prunes the green plants. If not cleaned in time, a large amount of garbage will be generated, and the fallen leaves and branches will directly fall on the soil. Since the humification process is slow, it is difficult to quickly adjust the fertility of the soil, and the change of the soil properties is also slow. SUMMARY

[0032] In actual use, the rotating disc 10, the rotating disc 17 and the transmission belt 18 can be replaced by chain transmission, so that the crushing gear 19 can have a stronger power source to crush branches and leaves;

[0033] The branches and leaves fallen by the pruning device 3 fall directly into the collecting sleeve 15, and then into the disc-shaped shell 14; in the disc-shaped shell 14, the rotation of the shaft 16 drives the rotation of the pulverizing gear 19 in the disc-shaped shell 14, and the branches and leaves are stirred and crushed by the rotating pulverizing gear 19, and the crushed material falls into the screening shell 20 through the connecting pipe 13; a plurality of small holes are formed in the bottom of the screening shell 20 for screening the crushed material, so that the crushed material falling into the soil is small enough to be easily absorbed by the soil.

[0034] The left side of the cam 12 is fixedly connected with the pushing device 21, which can push the crushed material accumulated in the screening shell 20 back and forth, so that the crushed material meeting the standard can quickly fall into the soil.

[0036] The transmission rod 26 is a rectangular rod, which makes the limited sliding of the transmission rod 26 in the limiting ring 25 more stable.

[0037] The left end center of the cylindrical cam 22 is fixedly connected with a shaft two 31, the left end of the shaft two 31 is fixedly connected with a cam two 32, the top of the cam two 32 is slidably connected with a pressing plate two 33, the upper surface of the pressing plate two 33 is fixedly connected with the bottom of the push-pull rod 28, the surface of the push-pull rod 28 is sleeved with a compression spring two 34, the two ends of the compression spring two 34 are fixedly connected with the opposite surfaces of the push-pull rod 28 and the pressing plate two 33, the left side of the screening shell 20 is fixedly connected with a conveying device 35, in use, the shaft two 31 is driven to make the cam two 32 rotate synchronously with the cylindrical cam 22, when the flange surface of the cam two 32 is in contact with the lower surface of the pressing plate two 33, the pressing plate two 33 will push the push-pull rod 28 to the highest position by overcoming the elastic force of the compression spring two 34, as shown in the figure, at this time, the push-pull rod 28 also moves to the position closest to the right end along with the transmission rod 26; when the concave surface on the cam two 32 is in contact with the lower surface of the pressing plate two 33, the pressing plate two 33 will move to the lowest position with the push-pull rod 28 under the elastic force of the compression spring two 34, at this moment, the push-pull rod 28 will be at the position closest to the left end correspondingly; Figure 4

[0038] Therefore, when the cam two 32 and the cylindrical cam 22 are continuously rotated, the push-pull rod 28 will make the push plate 30 move reciprocatingly in the screening shell 20 to the right upper side and the left lower side, when moving to the right upper side, the push plate 30 will be out of contact with the bottom of the inner wall of the screening shell 20, so that the debris accumulated in the right side direction of the push plate 30 can pass through and smoothly move to the left side of the push plate 30, and then during the left movement of the push plate 30, the debris is smoothly pushed to the left, so that the debris falling through the connecting pipe 13 will not be accumulated in large quantities in the right side direction of the push plate 30 along with the left and right movement of the push plate 30, which brings inconvenience to use;
