Description

Technical Field

[0001] The utility model relates to a branch shredder, in particular to a branch shredder with an anti-jamming blade. Background Art

[0002] A branch chipper is a mechanical device that is usually used to cut trees, branches and other plant materials into fragments or fine particles. These fragments can be used as compost, mulch material or other purposes. A branch chipper is usually driven by an electric or diesel engine with a rotating blade or cutter that is used to cut, crush or grind the raw plant material into smaller fragments. These machines are often used in gardening, agricultural clearing, forestry management and waste disposal. Existing branch chippers often cause branches to get stuck with the blades due to reasons such as large branch size, branch shape problems, and branches being put in too fast. Frequent branch jams may cause blade wear or even damage, affecting the normal operation of other mechanical parts. When a branch jam occurs, the operator needs to intervene and may need to touch the moving parts of the machine or be hooked by branches and drawn into the machine, which poses a high safety risk. Utility Model Content

[0003] The utility model discloses a branch shredder with an anti-jamming blade, wherein the power unit is connected to the cutting blade through a transmission shaft, the transmission shaft is connected to a transmission shaft sensor, a feeding wheel connected to a feeding motor is arranged in a feeding bin, the transmission shaft sensor is electrically connected to a controller, and the controller is electrically connected to a feeding motor. When too many branches enter the cutting bin through the feeding bin, causing the rotation speed of the cutting blade to be forced to slow down and causing an increase in the torque of the transmission shaft, the transmission shaft sensor can detect the increase in the torque of the transmission shaft. After the transmission shaft sensor detects the increase in the torque of the transmission shaft and sends a signal to the controller, the controller will control the feeding motor to stop working, thereby stopping feeding more branches into the cutting bin. The utility model solves the problem that the blades of the existing branch shredders are often stuck with branches after the transmission shaft sensor detects the increase in the torque of the transmission shaft after the branches are stuck, and the controller controls the feeding motor to stop working, thereby stopping feeding more branches into the cutting bin.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

When too many branches enter the pin cutting bin through the feed bin, the rotation speed of the cutting blade is forced to slow down, resulting in an increase in the transmission shaft torque, the transmission shaft sensor can detect the increase in the transmission shaft torque, and after the transmission shaft sensor sends a signal of detecting the increase in the transmission shaft torque to the controller, the controller will control the feed motor to stop working, thereby stopping feeding more branches into the pin cutting bin.

[0015] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation methods disclosed below.

[0017] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0018] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] The utility model provides a branch shredder with an anti-jamming blade, which effectively solves the problem in the prior art that branch shredders frequently jam with branches, causing blade wear or even damage. The utility model provides a transmission shaft sensor (32) in a cutting and pinning bin (3) to detect changes in transmission shaft torque, thereby controlling a feed motor (22) to stop working, thereby effectively avoiding safety risks and mechanical damage to the branch shredder caused by branches jamming.

[0020] The branch chipper structure comprises a support (1), a feed bin (2), a feed hopper (21), a cutting bin

[0021] (3), a cutting blade (31), a power unit (4), a discharge pipe (5) and a control chamber (6). The bracket (1) provides a stable structural foundation for the entire machine. The power unit (4) is connected to the cutting blade (31) through a transmission shaft to provide the necessary power for the cutting blade.

[0022] During use, branches first enter the feed bin (2) through the feed hopper (21), and the feed wheel (23) driven by the feed motor (22) pushes the branches to the cutting bin (3). After the cutting blade (31) cuts the branches, the fragments are discharged from the machine through the discharge pipe (5).

[0023] The key safety feature is that when branches are overloaded and blocked, the rotation speed of the cutting blade (31) decreases and the torque of the drive shaft increases. At this time, the drive shaft sensor (32) installed in the control chamber (6) can detect the torque change and quickly transmit the signal to the controller (7). After receiving the signal, the controller (7) immediately instructs the feed motor (22) to stop operating, preventing more branches from entering the cutting chamber (3), thereby avoiding the occurrence of overload.

[0024] In addition, the control compartment (6) is also provided with a battery to provide power to the controller (7) and the feeding motor (22), thereby ensuring that the branch shredder can operate normally even when there is no external power supply.

[0025] In order to improve the portability of the machine, wheels are provided under the bracket (1) to facilitate the user to move the machine to different work locations.

[0026] The cutting bin 3 is connected to the discharge pipe 5 to facilitate the discharge of the chopped branches.

[0027] The technical solution of the utility model not only effectively avoids blade damage and safety problems caused by stuck branches, but also improves the working efficiency of the branch chipper. Due to the design of the automatic stop feeding mechanism, when a potential blockage risk is detected, the machine automatically stops working, which greatly reduces the danger of operators in removing stuck branches and increases the safety of the use process.

[0028] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
