Description

Technical Field

[0001] The invention relates to the technical field of garden solid waste treatment, in particular to a waste recycling device for municipal garden construction. Background Art

[0002] Greening planting and pruning in municipal garden construction is a very important and highly professional task. Through reasonable pruning, the appearance of plants can be adjusted to make them present regular geometric shapes (such as spheres, squares, etc.), or to create a natural and beautiful posture, so that the overall landscape of the garden has a more layered and rhythmic sense, enhances visual beauty, and is in harmony with the surrounding environment to meet people's aesthetic needs. Secondly, cutting off diseased branches, dead branches, and overcrowded branches can improve the ventilation and light transmission conditions of plants, reduce the chance of pests and diseases breeding, enable plants to better photosynthesize, and promote the sprouting of new shoots. Pruning can promote the development and root growth of some fast-growing and highly expansive plants, enhance their vitality and resistance to adversity. For some plants that grow quickly and have strong expansibility, pruning can limit their growth range to avoid squeezing or encroaching on other surrounding plants, garden buildings or facilities, while guiding the plants to grow in the expected direction and maintaining the rationality of the garden space layout. Finally, the pruned branches, leaves, etc. must be cleaned out of the garden site in a timely manner to avoid accumulation and breeding of pests and diseases, while keeping the garden environment clean and beautiful. They can be collected in a centralized manner and transported to a landfill or crushed and composted.

[0003] At present, the garbage generated after pruning is mostly the branches and leaves of trees and plants, as well as cleared weeds and other plant garbage. Usually, this type of garbage needs to be transported to designated places for proper treatment. However, this type of garbage is too fluffy and large in size, which takes up space. After simple crushing, the granular garbage is easy to scatter during transportation, making transportation difficult. In addition, the equipment makes a lot of noise when processing the garbage, affecting the surrounding environment. Summary of the invention

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Refer to the attached Figure 1-13 A garbage recycling device for municipal garden construction consists of a body 1, a knife holder 10 arranged in the body 1, a main shaft arranged in the knife holder 10, a crushing knife arranged on the main shaft, an upper end cover 6 installed at the upper end of the body 1, a lower end cover 17 installed at the lower end of the body 1, and a shell installed on the lower end cover. The garbage recycling device is used to crush recyclable garbage such as branches, green plants, weeds, etc. generated during garden construction.

[0045] The technical point of the present invention is that two first firewood inlets 7 are symmetrically installed on the side wall of the machine body 1, one of which is equipped with a hopper 4, and the firewood inlet is used to fill miscellaneous garden waste such as leaves, weeds, and shrubs through the hopper 4, and the other first firewood inlet 7 without a hopper 4 is used to fill larger and thicker tree trunks. Under its inclined structure, the larger and thicker tree trunks can slide into the machine body 1 under the action of gravity and contact with the blade 22 installed on the knife holder 10. The side wall of the knife holder 10 is evenly provided with a plurality of first installation ports. The first and second mounting ports are both obliquely fixedly connected with a back plate 23, one end of the back plate 23 is fixedly connected with an arc-shaped baffle plate 24, one side of the back plate 23 is fixedly connected with the blade 22 by bolts, and the trunk debris cut by the blade is hit by the arc-shaped baffle plate 24 and flies into the tool holder 10, a guide ring 13 and a blocking ring 14 are fixedly connected in the machine body 1, the tool holder 10 is sleeved in the guide ring 13 and the blocking ring 14, a plurality of push plates 12 are fixedly connected to the side wall of the tool holder 10, and the inclined structure of the guide ring 13 can be The debris that has not entered the tool holder 10 is pushed into the second installation port by the push plate 12, so that the debris can enter the tool holder 10. The multiple push plates 12 are in contact with the guide ring 13. The side wall of the tool holder 10 is fixedly connected with multiple positioning rollers 11. The rollers of the multiple positioning rollers 11 are in contact with the inner side of the body 1. The positioning rollers 11 can keep the tool holder 10 concentric with the base 1 and can increase the carrying capacity of the tool holder 10 so that the blade 22 can work stably. The side wall of the tool holder 10 is fixedly connected with multiple tooth plates 25. When the rack 10 rotates, the tooth plate 25 can roughen the part of the trunk that contacts the knife rack, and the roughening can destroy the plant fiber structure of the trunk, so that the blade 22 can easily chop the trunk and reduce the resistance encountered by the blade 22 when working. In this way, the rotating multiple blades 22 can be used to peel and crush the trunk. Two second firewood inlets 3 are symmetrically installed on the side wall of the body 1. The second firewood inlet 3 is below the first firewood inlet 7 and is mainly used to add relatively fluffy branches. Since the entrance of the second firewood inlet 3 is designed according to a certain cutting angle, such as Figure 1 and Fig. 9 As shown, the weight of the branch is small. When entering at a certain cutting angle, the blade 22 close to the inner wall of the body 1 can also peel the branch, and the blade 22 and the branch are also in oblique contact during peeling. Therefore, when rotating, the friction between the oblique cutting blade 22 and the branch can make the branch move forward automatically. In addition, the number of second mounting openings for fixing the blade 22 is small, so a larger area of ​​the solid part is left on the tool holder 10. The solid part can prevent the branch from directly entering the tool holder, and the tooth plate 25 can also achieve the effect of pulling the branches to destroy the plant fibers, which is convenient for controlling the particle size of the sawdust peeled off, so the second firewood inlet 3 is designed to be fixed horizontally.

[0046] The tool holder 10 is a roller structure. The tool holder 10 is installed in the body 1 and is equipped with multiple blades 22. The upper end of the main shaft is rotatably connected to the middle of the upper end cover 6 through a ball bearing. A crushing knife is installed on the shaft wall of the main shaft. When the roller tool holder 10 rolls and peels, the wood chips cut by the blade 22 are in the form of flakes. Due to the acute angle design of the cutting edge of the blade 22 (less than 45° and greater than 30°), the peeling thickness is controlled within 1 cm. At this time, the cutting edge of the blade 22 can not only cut the wood chips, but also squeeze the wood chips to change their fiber structure. After the wood chips enter the tool holder 10, the crushing knife can be used to perform secondary crushing on the wood chips. At this time, the wood chips can be crushed into particles, and the granular wood chips are discharged through the discharge port 15 provided at the lower end of the tool holder 10.

[0047] The upper end cover 6 is fixed to the upper end of the machine body 1, and a first transmission mechanism is installed on the upper end cover 6. A second transmission mechanism is installed on the side wall of the tool holder 10, and the second transmission mechanism is installed in the machine body 1. The first transmission mechanism and the second transmission mechanism are both provided with a gear ring 19, a hydraulic motor 5 and a plurality of gear shafts 9 of the same type. The plurality of gear shafts 9 are symmetrically meshed on the side wall of the gear ring 19, and each gear ring 19 is provided with at least four gear shafts 9. The hydraulic motor 5 of the first transmission mechanism is fixed to the upper end of the upper end cover 6, and the gear ring 19 of the first transmission mechanism is fixed to the upper end of the tool holder 10. The upper end cover 6 is rotatably connected to the plurality of gear shafts 9 through ball bearings, and the upper end of one of the gear shafts 9 is fixedly connected to the output shaft of the hydraulic motor 5 of the first transmission mechanism. The inner side of the machine body 1 is rotatably connected to the shaft walls of the plurality of gear shafts 9 through a bearing seat, and the lower end of one of the gear shafts 9 is fixedly connected to the output end of the hydraulic motor 5 of the second transmission mechanism, and the hydraulic motor 5 of the second transmission mechanism is fixed in the machine body 1, refer to Figure 2 At this time, the first transmission mechanism and the second transmission mechanism are arranged symmetrically. Under the control of the hydraulic motor 5 of the same model and the same hydraulic control station (not shown in the figure), a working condition of close to or equal speed and torque is achieved, so that both ends of the tool holder 10 can provide torque. The hydraulic motor 5 adopts a low-speed hydraulic motor with a rotation speed of 400-600 rpm. This technology has been widely used in life, and those skilled in the art have already known it, so no further elaboration is made.

[0048] The lower end of the shell is fixedly connected with a lower end cover 17, which is fixed to the lower end of the body 1 by bolts. The tool holder 10 is sleeved on the shell, and a connecting piece is installed on the upper end of the shell. The connecting piece is rotatably connected to the inner side of the tool holder 10. The connecting piece includes a polygonal shaft. The upper end of the shell is sleeved with the polygonal shaft 39 through a polygonal hole. The lower end of the polygonal shaft 39 is threadedly connected with a fixing bolt through a threaded hole. The upper end of the polygonal shaft 39 is fixedly connected with a central shaft 38, and a positioning plate is fixedly connected to the shaft wall of the central shaft 38. The positioning plate contacts the upper end of the shell. A fixing frame is rotatably connected to the shaft wall of the central shaft 38 through a needle bearing, and the fixing frame is fixedly connected to the same axis. In the tool holder 10, the polygonal axis 39 and the central axis 38 are fixed to the upper end of the shell by fixing bolts, and the shell is used to support the tool holder 10 to ensure its stability when subjected to rotational force. The bottom shell 18 is fixed to the lower end of the lower end cover 17 by bolts and is provided with a discharge pipe. The discharge pipe can be connected to conveying equipment such as a screw conveyor and a belt conveyor to transport the processed garbage to the transportation equipment, or directly bag it for transportation. The chassis 2 is rotatably connected to two inflatable wheels, and a traction frame is provided on one side of the chassis 2. The chassis 2 enables the discharge pipe to have a height above the ground, which meets the requirements for assembling the conveying equipment. At the same time, the chassis 2 can also make the equipment draggable and move.

[0049] In order to further crush the cut pieces, a crushing knife is arranged on the main shaft, and a gear set is arranged on the main shaft. The gear set is used as power output through the rotation of the tool holder 10. After the gear set is reversed, the tool holder 10 and the main shaft rotate in opposite directions, and the speed of the main shaft is greater than the rotation speed of the tool holder 10. Specifically, a first gear 31 is fixedly connected to the shaft wall of the main shaft, and a plurality of second gears 30 are arranged on the side wall of the first gear 31 in meshing engagement. The plurality of second gears 30 are rotatably connected to the side wall of the upper end cover 6 through a support shaft, and the plurality of second gears 30 are meshed together with a An inner gear ring 8 is coaxially fixed to the upper end of the tool holder 10. A support frame is rotatably connected to the shaft wall of the main shaft through a needle bearing. The support frame is fixed in the tool holder 10. In this way, the second gear 30 rotating on the upper end cover 6 can be driven to rotate when the inner gear ring 8 rotates. The first gear 31 is driven by the second gear 30 to rotate the main shaft. When the main shaft rotates, it is fixed to the shaft wall of the main shaft through the fixed plate configured on the crushing knife. The side wall of the fixed plate is tilted and fixedly connected with multiple inclined plates 33. One end of each of the multiple inclined plates 33 is fixedly connected to a cross plate. One end of the cross plate is connected to the The shaft wall of the horizontal axis is fixedly connected, and a blade is provided on one side of the inclined plate 33 and the horizontal plate. A plurality of crushing teeth 34 are fixedly connected to the side wall of the inclined plate 33. At this time, the three-dimensional crushing knife composed of the crushing teeth 34, the inclined plate 33 and the horizontal plate can impact and cut the falling wood chips, so that the flaky materials are further broken into particles, and finally fall on the cone plate 26 fixedly connected in the tool holder 10. The upper end of the cone plate 26 is provided with a platform, and the inner side of the cone plate 26 contacts the lower end of the inclined plate 33. The lower end of the cone plate 26 is provided with a sleeve, which is sleeved on the main shaft. On the shaft wall, a plurality of crushing plates 37 are fixedly connected to the lower end of the fixed plate. The plurality of crushing plates 37 are all located in the sleeve and are provided with a bending portion 36. The plurality of bending portions 36 are all located at the lower end pipe mouth of the sleeve and are fixedly connected with a circular ring. When the particulate matter falls through the sleeve, the crushing plates 37 can further crush the wood chips in a smaller space. In addition, the bending portion 36 can further crush the wood chips during discharge. Finally, the wood chips are crushed again by a plurality of cross-cutting knives 35 fixedly connected to the lower end of the main shaft and a V-shaped knife 27 fixedly connected to the plurality of cross-cutting knives 35.

[0050] A first fixed ring 42 is fixedly connected to the side wall of the shell, a second fixed ring 21 is fixedly connected in the discharge port 15, and a plurality of distribution rods 43 are fixedly connected to the upper edge of the second fixed ring 21. The distribution rods 43 guide the wood chip particles into between the first fixed ring 42 and the second fixed ring 21. A plurality of fan-shaped plates 41 are fixedly arranged in the first fixed ring 42 and the second fixed ring 21. The plurality of fan-shaped plates 41 form a plurality of first dispersion channels. The wood chip particles continuously pass through the plurality of first dispersion channels and are continuously kneaded and crushed by a plurality of protrusions arranged at the upper and lower ends of the fan-shaped plates 41.

[0051] In addition, an outer convex portion is provided on the side wall of the shell, and a plurality of first pyramids 20 are fixedly connected to the outer convex portion. A plurality of second pyramids 32 are fixedly connected in the discharge port 15. The plurality of first pyramids 20 and the plurality of second pyramids 32 are staggered to form a plurality of second dispersion channels. The kneaded and crushed wood chip particles are further kneaded and crushed by the staggered first pyramids 20 and the second pyramids 32, and the wood chips can be fully crushed into small particles.

[0052] The lower end cover 17 is an annular structure, and an expansion part 29 is provided at the lower end of the shell body, and the expansion part 29 is fixed in the hole at the center of the lower end cover 17. The side wall of the expansion part 29 is provided with a plurality of compression channels 40, and the opening of the compression channel 40 is provided with a chamfer. The lower end of the discharge port 15 is provided with a flaring part 16, and the upper end of the lower end cover 17 is provided with an annular groove, and the flaring part 16 is sleeved in the annular groove. A plurality of uniformly distributed extrusion blocks 28 are fixedly connected to the inner side of the flaring part 16. The small particle wood chips formed after being fully crushed enter the gap between the expansion part 29 and the flaring part 16 provided at the lower end of the shell body, and finally fall into the flaring part 16 provided on one side of the extrusion block 28. In the expansion part 44 of the arc-shaped structure, the wood chip particles in the expansion part 22 are squeezed by the compression part 45 provided on one side of the squeezing block 28. Since the compression part 45 is in contact with the expansion part 29, the wood chips are compressed into the compression channel 40. At this time, the compressed wood chips form large particles of fixed shape in the compression channel 40, that is, biomass particles re-compressed from crushed branches, green plants, weeds, etc. The structure of the biomass particles is compact at this time, which can greatly reduce the volume of recyclable garbage such as branches, green plants, weeds, etc., and after drying, they can form biomass fuel for power generation, agricultural fungus planting, mushroom bag processing, organic fertilizer fermentation, etc.

[0053] The effect of the technology of the present invention is that, through the designed tool holder 10, the blade 22 can make a circular motion to independently crush and recycle recyclable garbage such as tree trunks, branches, green plants, weeds, etc., and the rotary cutting of the blade and the "biting" of the tooth plate 25 can achieve preliminary crushing of recyclable wood waste. When the rotary cutting mode acts on wood fibers with a high water content, it can generate less resistance and is not easy to damage the tool, and can also reduce the noise problem generated by traditional equipment during crushing.

[0054] After the initial crushing, considering that the wood chips are large in volume, they still take up a lot of space during transportation and are easy to scatter. Therefore, by arranging a crushing knife, a cross-cutting knife 35, a V-shaped knife 27, a crushing plate 37, a fan-shaped plate 41, a first pyramid 20 and a second pyramid 32 in the knife holder 10 from top to bottom, the cut wood chips can be further crushed into small particles of wood chips. At this time, the particle size of the wood chips is further reduced, so that the volume of the crushed garbage is smaller and it is more convenient to transport and store.

[0055] Since the crushed wood chip particles still have a certain volume, in order to further reduce their volume, the extrusion block 28 and the shell are arranged to cooperate so that the wood chip particles can be further squeezed by the compression part 45 into the compression channel 40, and the wood chips are further compressed in the compression channel 40 to form particles with a dense texture. Therefore, the final particles can not only save space and facilitate transportation, but also can be used as a new recycled material in production and life after drying.
