Description

TECHNICAL FIELD

[0001] The present utility model relates to the technical field of forestry, and in particular to a dead leaf treatment apparatus for forestry use. BACKGROUND ART

[0002] Forestry is a science that studies the formation, development, management and administration of forests, as well as the protection and utilization of forest resources. In forestry practices such as forest tending, forest land sanitation management, forest road maintenance, and cleaning of operation sites, a large amount of dead branches and dead leaves often accumulate on the ground. Timely collection and treatment of these dead leaves is advantageous for reducing the risk of forest fires, improving the sanitary conditions of forest land, promoting nutrient cycling and subsequent forest cultivation operations, and is an important part of forestry production and forest protection and management.

[0003] As a result of search, a Chinese patent document with the application number 202123340714.1 discloses a dead leaf collecting and baling machine for landscape gardens. The apparatus is provided with a machine shell. When collecting dead leaves, the leaf inlet pipe is aligned with the position of fallen leaves, and the dead leaves are collected through the mutual cooperation of the suction fan, the connecting pipe and the leaf inlet pipe. After the collection is completed, the collection box can be pulled out from the inside of the machine shell, so that the dead leaves collected and baled in the collection box can be cleaned in a concentrated manner.

[0004] However, when this type of apparatus is directly used in forestry work scenarios, since the components of dead leaves in forest land are mostly fluffy dead branches and dead leaves, the volume of the collection box will become full in a short time, which makes it necessary to process the collection box multiple times in the operation of collecting fallen leaves under the forest, resulting in a large waste of working time. In addition, problems such as clogging of the sieve mesh are prone to occur during the collection process, which seriously affects the use efficiency of the apparatus, and even causes damage to the apparatus and induces safety hazards.

[0005] Therefore, there is an urgent demand for a dead leaf treatment apparatus for forestry use that solves the above problems. SUMMARY OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION

[0006] The purpose of this invention is to provide a leaf disposal device for forestry that solves the problems encountered when collecting and processing dead branches and leaves in forestry work. In such cases, the leaf components are often relatively fluffy, causing the collection box to fill up quickly, requiring the collection box to be processed multiple times during leaf collection work, resulting in a large waste of work time. Furthermore, problems such as blockage of the sieving screen are likely to occur during the collection process, seriously affecting the efficiency of the device, and even leading to damage to the device and creating safety hazards.

[0015] The technical means of the present invention will be described below with reference to Figures 1 to 5. The present invention comprises a box body 1, a motor 2 fixedly connected to the outer wall of the box body 1, a rotating shaft 3 rotatably connected to the inner wall of the box body 1, the output end of the motor 2 connected to the rotating shaft 3, and crushing blades 4 fixedly connected to the outer wall of the rotating shaft 3, with two to five sets of crushing blades 4 uniformly arranged along the outer wall of the rotating shaft 3. Furthermore, it comprises a transmission member fixedly connected to the outer wall of the rotating shaft 3 and a collection member fixedly connected to the outer wall of the box body 1. The transmission member includes a driven member fixedly connected to the outer wall of the rotating shaft 3 and a sieving member connected to the inner wall of the box body 1, the driven member fixedly connected to the sieving member.

[0016] As shown in Figures 3 to 5, the driven member includes a first bevel gear 5, a second bevel gear 6, a connecting rod 7, a third bevel gear 8, a fourth bevel gear 9, and a first limiting frame 10. The first bevel gear 5 is fixedly connected to the outer wall of the rotating shaft 3, the second bevel gear 6 is connected to the first bevel gear 5 by meshing, the connecting rod 7 is fixedly connected to the outer wall of the second bevel gear 6, the third bevel gear 8 is fixedly connected to the bottom wall of the connecting rod 7, the first limiting frame 10 is fixedly connected to the inner wall of the box body 1, the first limiting frame 10 is rotatably connected to the connecting rod 7, the fourth bevel gear 9 is connected to the third bevel gear 8 by meshing, and the fourth bevel gear 9 is fixedly connected to the sieving member. When motor 2 drives and rotates the rotating shaft 3, the first bevel gear 5, which is fixedly connected to the rotating shaft 3, rotates synchronously. The first bevel gear 5 rotates the second bevel gear 6 synchronously, and at the same time rotates the third bevel gear 8 via the connecting rod 7, which in turn rotates the fourth bevel gear 9 that meshes with it, and the connecting rod 7 is restricted by the first limiting frame 10. The rotation of the fourth bevel gear 9 simultaneously rotates the sieve member.

[0017] As shown in Figures 3 to 5, the sieving member includes a rotating column 11, an eccentric wheel 12, a lifting bracket 13, a second limiting frame 14, a sieving mesh 15, and telescopic rods 16. The rotating column 11 is rotatably connected to the inner wall of the box body 1, the rotating column 11 is fixedly connected to the fourth bevel gear 9, the eccentric wheel 12 is fixedly connected to the side wall of the rotating column 11, the lifting bracket 13 is slidably connected to the eccentric wheel 12, the sieving mesh 15 is fixedly connected to the bottom wall of the lifting bracket 13, the second limiting frame 14 is rotatably connected to the outer wall of the rotating column 11, the second limiting frame 14 is slidably connected to the lifting bracket 13, and two sets of telescopic rods 16 are provided symmetrically on the outer wall of the sieving mesh 15 with respect to the rotation axis 3. The sieving member is driven by the fourth bevel gear 9, which causes the rotating column 11, to be fixedly connected to it, to rotate, and simultaneously rotates the eccentric wheel 12. Subsequently, the lifting bracket 13 repeatedly moves up and down under the constraints of the second limiting frame 14, and in conjunction with the symmetrically provided telescopic rod 16, causes the sieving screen 15 to repeatedly move up and down, sieving the crushed fallen leaves.

[0018] As shown in Figures 1 and 2, the collection member includes a suction port 17, a connecting pipe 18, and a suction fan 19. The connecting pipe 18 is fixedly connected to the inner wall of the box body 1, the suction port 17 is fixedly connected to the outer wall of the connecting pipe 18, and the suction fan 19 is fixedly connected to the outer wall of the connecting pipe 18. When it is necessary to clean fallen leaves, etc., from the forest stand surface, forest road, or work site, the suction fan 19 is opened, and the fallen leaves enter the device through the suction port 17 and the connecting pipe 18.

[0019] As shown in Figures 1 and 2, a collection box 20 is detachably connected to the inner wall of the box body 1, a handle 21 is fixedly connected to the outer wall of the collection box 20, a push bar 22 is fixedly connected to the side wall of the box body 1, and swivel wheels 23 are provided on the bottom wall of the box body 1.

[0020] Specifically, when using this forestry leaf removal device, if it is necessary to clean fallen leaves from the forest stand surface, forest roads, or work sites, the suction fan 19 is opened, and the fallen leaves enter the device through the suction port 17 and the connecting pipe 18. When the motor 2 is started, the motor 2 drives the rotating shaft 3 to rotate, and the crushing blades 4, which are fixedly connected to the rotating shaft 3, rotate in sync with the rotation of the rotating shaft 3, crushing the sucked-in fallen leaves. At the same time, when the motor 2 drives the rotating shaft 3 to rotate, the first bevel gear 5, which is fixedly connected to the rotating shaft 3, rotates in sync with the first bevel gear 5, which in turn rotates the second bevel gear 6, and simultaneously rotates the third bevel gear 8 via the connecting rod 7, which in turn rotates the fourth bevel gear 9 that meshes with it, and the connecting rod 7 is restricted by the first limiting frame 10. The rotation of the fourth bevel gear 9 simultaneously rotates the sieving member. The sieving member is driven by a fourth bevel gear 9, which rotates a fixedly connected rotating column 11, simultaneously rotating an eccentric wheel 12. Subsequently, the lifting bracket 13 repeatedly moves up and down within the limits of the second limiting frame 14, and in conjunction with the symmetrically provided telescopic rod 16, repeatedly moves the sieving screen 15 up and down to sieve the crushed fallen leaves. After sieving is complete, the crushed fallen leaves enter the collection box 20, occupying little space and allowing for the collection of a relatively large amount of fallen leaves at once, and the handle 21 is used for cleaning.
