Description

Technical Field

[0001] The utility model relates to the technical field of landscaping, and particularly relates to a pruning device for municipal gardens. Background Art

[0002] A large number of lawns are often laid in gardens to ensure the greening area, and the lawns need to be trimmed regularly to ensure the overall aesthetics. Many pruning devices have been proposed in the prior art for cutting and trimming lawns, but most of the pruning devices only cut the lawns, and the cut weeds still need to be manually collected by workers (usually the cut weeds are centrally recycled and utilized), which increases the labor of the operators. Of course, there are also pruning devices that can perform packing treatment, that is, after the device cuts the lawn, the cut weeds will be directly conveyed to a storage box. However, because the weeds themselves are relatively soft, they will be fluffy when falling into the storage box, which will result in a very limited amount of weeds actually stored inside the storage box. The construction workers frequently stop the machine to transfer the weeds inside the storage box, which has a certain impact on the trimming efficiency of the entire lawn. Based on this, the present utility model is proposed. Content of the Utility Model

[0003] In order to solve the above technical problems existing in the prior art, the present utility model provides a pruning device for municipal gardens.

[0004] To achieve the above object, the present utility model provides the following technical solution: A pruning device for municipal gardens, comprising a storage box fixed on a vehicle frame. The top of the storage box is open and connected with a transfer box. A conveying mechanism and a cutting mechanism are successively distributed at the front end of the vehicle frame along its traveling direction. A guide plate distributed obliquely is connected to one side of the top of the storage box facing the conveying mechanism;

[0005] A material receiving plate capable of moving vertically is arranged inside the storage box. A second notch adapted to the cross section of the material receiving plate is opened at the bottom of the transfer box.

[0006] An L-shaped pushing plate is slidably installed inside the storage box. The bottom of the L-shaped pushing plate is attached to the upper plate surface of the material receiving plate, and the top extends horizontally outside the storage box. Two second cylinders are installed on the outer wall of the storage box, and the piston rods of the second cylinders are fixedly connected to the vertical parts of the L-shaped pushing plate.

[0007] Preferably, the length of the material receiving plate is L1, the length inside the storage box is L2, and the thickness of the vertical part of the L-shaped pushing plate is D, and L1 = L2 - D.

[0008] Preferably, a connecting plate is connected to the side of the material receiving plate facing away from the L-shaped pushing plate in the vertical direction. The connecting plate is arranged through the storage box in the thickness direction thereof. A first cylinder is installed on the outer wall of the transfer box in the vertical direction. The piston ends of the first cylinders are fixedly connected to the corresponding connecting plates respectively. A limiting groove matching the movement track of the connecting plate is formed on the outer wall of the transfer box corresponding to the movement track of the connecting plate.

[0009] Preferably, a discharge port is formed at one end of the transfer box along its length direction, and the end of the discharge port is hinged to the vehicle frame. Two brackets are fixed to the upper end of the vehicle frame. One end of the transfer box is supported by the brackets, and the other end is rotatably connected to the brackets.

[0010] Preferably, a first notch is formed at the top of the transfer box along its length direction.

[0011] Preferably, the conveying mechanism adopts a belt conveying structure, and several baffles are arranged at equal intervals on the belt.

[0012] Preferably, the cutting mechanism is arranged at the bottom of the conveying mechanism and includes two rotating disks rotatably connected to the vehicle frame. The centers of the two rotating disks are connected by a central rod, and several cutting knives are installed between the circumferential surfaces of the two rotating disks.

[0013] Preferably, a motor is fixed to the upper end of the vehicle frame. A fourth sprocket and a second sprocket are fixedly sleeved on the motor shaft of the motor in sequence. A third sprocket is fixedly sleeved outside the driving roller at one end of the conveying mechanism. The central shaft in the cutting mechanism extends to the outside and is fixedly sleeved with a first sprocket. A first chain is sleeved between the first sprocket and the second sprocket, and a second chain is sleeved between the third sprocket and the fourth sprocket. The diameter of the second sprocket is larger than that of the first sprocket.

[0014] Preferably, the diameter ratio of the second sprocket to the first sprocket is 5:1.

[0015] Compared with the prior art, the utility model provides a pruning device for municipal gardens, which has the following beneficial effects:

[0016] (1) In the present application, an L-shaped pushing plate is slidably installed in the storage box. After the cut weeds enter the storage box along the guide plate, the second cylinder drives the L-shaped pushing plate to slide periodically in the storage box, so as to continuously extrude the weeds, making the fluffy weeds evenly fill the entire storage box, thereby prolonging the downtime of the pruning device for transferring weeds each time and ensuring a certain lawn pruning efficiency.

[0017] (2) When the storage box is full of weeds, the first cylinder drives the material holding plate to move upward inside the storage box. The cooperation between the material holding plate and the storage box can transfer the weeds upward into the transfer box. And when the material holding plate completely disengages from the storage box, the transfer box can rotate relative to the vehicle frame, so as to pour the weeds inside the transfer box into the bag. During the process of the storage box collecting weeds, since both the material holding plate and the connecting plate are inside the storage box, at this time, the transfer box can remain fixed relative to the vehicle frame and always be in a horizontal state, avoiding shaking during the walking process of the device.

Detailed Embodiments

[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but only represents the selected embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figures 1-6 shown, this embodiment provides a pruning device for municipal gardens, which includes a storage box 2 fixed on a vehicle frame 1. The top of the storage box 2 is open and connected with a transfer box 3. Two groups of wheels 6 are distributed on both sides of the vehicle frame 1. Construction workers hold the pusher on the vehicle frame 1 to apply a thrust to the entire device, and the entire device moves forward under the action of the wheels 6. A conveying mechanism 4 and a cutting mechanism 5 are successively distributed at the front end of the vehicle frame 1 along its traveling direction. One side of the top of the storage box 2 facing the conveying mechanism 4 is connected with an inclined guide plate 26. During the movement of the entire device, the cutting mechanism 5 rotates at a high speed to cut the lawn, and the cut weeds fall to the bottom of the conveying mechanism 4 under the action of the rotation of the cutting mechanism 5. The conveying mechanism 4 is also inclined, and its top is lapped with the guide plate 26. The weeds are transported by the conveying mechanism 4 and fall on the guide plate 26, and finally slide into the storage box 2 along the guide plate 26. After the storage box 2 is full of weeds, they are transferred to the transfer box 3. An outlet 18 is provided on one side of the transfer box 3. Since the transfer box 3 is rotatably connected to the vehicle frame 1, construction workers can rotate the transfer box 3 to pour out the weeds inside. When actually collecting weeds, construction workers can open a bag and align it with the outlet 18 on one side of the storage box 2, and rotate the transfer box 3 to directly pour the weeds into the bag.

[0029] In the above solution, although the cut weeds slide into the interior of the storage box 2, the weeds are relatively fluffy inside the storage box 2. Therefore, the actual amount of weeds stored in the storage box 2 is not much. To reduce the frequency of construction workers stopping the machine to collect weeds, an L-shaped pushing plate 25 is slidably installed inside the storage box 2. The bottom of the L-shaped pushing plate 25 is attached to the upper plate surface of the material receiving plate 23, and the top extends horizontally outside the storage box 2. Two second cylinders 24 are installed on the outer wall of the storage box 2. The piston rods of the second cylinders 24 are fixedly connected to the vertical parts of the L-shaped pushing plate 25. The L-shaped pushing plate 25 is driven to slide inside the storage box 2 by the second cylinders 24. After the weeds slide into the interior of the storage box 2 along the guide plate 26, the second cylinders 24 periodically push the L-shaped pushing plate 25 to slide inside the storage box 2, so as to evenly fill the entire storage box 2 with weeds. And as the L-shaped pushing plate 25 continues to slide, it can also compact the weeds inside the storage box 2, so that the amount of weeds stored in the storage box 2 each time is more. The reason why the L-shaped pushing plate 25 is adopted in this application is that when the L-shaped pushing plate 25 slides towards the middle of the storage box 2 inside the storage box 2, the horizontal part of the L-shaped pushing plate 25 can also carry the weeds on the guide plate 26. When the piston rods of the second cylinders 24 retract, the weeds carried on the L-shaped pushing plate 25 fall into the interior of the storage box 2 under the blocking action of the inner wall of the storage box 2.

[0030] When the weeds inside the storage box 2 are full, they need to be transferred to the transfer box 3. To achieve this goal, a material receiving plate 23 is provided at the bottom inside the storage box 2. In the initial state, the material receiving plate 23 is located at the bottom of the storage box 2, with its width being the same as the inside of the storage box 2, while its length is slightly smaller than that of the storage box 2. Let the length of the material receiving plate 23 be L1 and the length inside the storage box 2 be L2, and the thickness of the vertical part of the L-shaped pushing plate 25 be D. L1 = L2 - D, so as to avoid interference between the material receiving plate 23 and the L-shaped pushing plate 25 when the material receiving plate 23 moves upward. On the side of the material receiving plate 23 facing away from the L-shaped pushing plate 25, a connecting plate 22 is connected vertically. The connecting plate 22 is arranged through the storage box 2 in the thickness direction. A first cylinder 20 is also installed vertically on the outer wall of the transfer box 3. The piston end of the first cylinder 20 is fixedly connected to the corresponding connecting plate 22 respectively. The material receiving plate 23 is driven by the first cylinder 20 to move upward inside the storage box 2. A limiting groove 21 matching the movement track of the connecting plate 22 is opened on the outer wall of the transfer box 3 corresponding to the movement track of the connecting plate 22. The material receiving plate 23 carries the weeds upward, and the connecting plate 22 is inserted into the corresponding limiting groove 21 to ensure that the weeds do not leak out of the limiting groove 21. A second notch 27 matching the cross-section of the material receiving plate 23 is opened at the bottom of the transfer box 3. When the material receiving plate 23 rises to be exactly level with the second notch 27, the first cylinder 20 is stopped. Since the end of the transfer box 3 with the discharge port 18 is hinged to the vehicle frame 1 (a bracket 19 is fixed at the upper end of the vehicle frame 1, one end of the transfer box 3 is supported by the bracket 19, and the other end is rotatably connected to the bracket 19), and the connecting plate 22 also completely disengages from the storage box 2, the construction personnel can perform a rotation operation on the transfer box 3. After the transfer box 3 rotates to a certain inclination angle, the weeds can slide out from the discharge port 18 under the action of gravity.

[0031] In addition, a first notch 17 is also opened along the length direction at the top of the transfer box 3. During the process of dumping the weeds, personnel can reach into the transfer box 3 through the first notch 17 and use their hands to stir the weeds to accelerate the dumping speed of the weeds.

[0032] After the weeds inside the transfer box 3 are dumped, the transfer box 3 is placed flat again. At this time, the two first cylinders 20 drive the material receiving plate 23 to move into the storage box 2, and the connecting plate 22 is inserted into the storage box 2 again. At this time, the entire transfer box 3 can always remain in a horizontal state and stay fixed, preventing the transfer box 3 from shaking during the walking process of the entire device, and ensuring that the transfer box 3 can only rotate when dumping the weeds.

[0033] As for the conveying mechanism 4 in this application, the current belt conveying structure can be adopted. The difference is that since the entire conveying mechanism 4 is inclined, in order to prevent weeds from slipping on the conveying mechanism 4, several baffles 16 are arranged at equal intervals on the belt. The cutting mechanism 5 is arranged at the bottom of the conveying mechanism 4 and includes two rotating disks 7 rotatably connected to the vehicle frame 1. The centers of the two rotating disks 7 are connected by a central rod, and several cutting knives 8 are installed between the circumferential surfaces of the two rotating disks 7. By driving one of the rotating disks 7 to rotate, several cutting knives 8 rotate synchronously, thereby realizing the cutting of the lawn. For the actions of the conveying mechanism 4 and the cutting mechanism 5, this utility model adopts a set of driving systems. Specifically, a motor 12 is fixed at the upper end of the vehicle frame 1. A fourth sprocket 15 and a second sprocket 11 are sequentially and fixedly sleeved on the motor shaft of the motor 12. A third sprocket 13 is fixedly sleeved outside the driving roller at one end of the conveying mechanism 4. After the central shaft in the cutting mechanism 5 extends to the outside, a first sprocket 9 is fixedly sleeved. A first chain 10 is sleeved between the first sprocket 9 and the second sprocket 11, and a transmission connection is established by sleeving a second chain 14 between the third sprocket 13 and the fourth sprocket 15. The diameter of the second sprocket 11 is larger than that of the first sprocket 9, and the diameter ratio between the two is preferably set to 5:1. In this way, when the motor 12 drives the fourth sprocket 15 and the second sprocket 11 to rotate, the conveying mechanism 4 rotates slowly, while the cutting mechanism 5 rotates at five times the speed to form the cutting of the lawn.
