Description

Technical Field

[0001] This utility model relates to the field of mushroom cultivation technology, and in particular to a branch cutting machine. Background Technology

[0002] In the large-scale cultivation of fungi (especially wood-rotting fungi, such as Armillaria mellea, shiitake mushrooms, wood ear mushrooms, oyster mushrooms, and enoki mushrooms), lignocellulose (such as branches and sawdust) is relied upon as a nutrient source, but untreated branches cannot be directly used to make culture media.

[0003] Currently, branches need to be pre-treated and cut into sections. The cutting process mostly relies on manual labor, which is inefficient and costly. Furthermore, manual cutting may result in the discarding of some branches due to the difficulty in sawing thin branches or the labor involved in cutting thick branches, leading to waste. Additionally, the cut lengths are not uniform. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a branch cutting machine that automatically completes the cutting process simply by manually feeding in the branches. The branches are cut evenly, with high efficiency, and labor costs are saved.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: A branch cutting machine includes a frame, a cover installed on the top of the frame, a cutter shaft rotatably connected inside the cover, an assembly plate installed at the front end of the cutter shaft, three blades detachably installed on the circumference of the assembly plate, a feed inlet on the front side of the cover, a gasket that mates with the blades fixed at the bottom of the feed inlet, and a discharge channel connected to the bottom of the cover.

[0006] Preferably, the assembly plate includes a base plate, a filling plate, and a pressing plate. The base plate, the filling plate, and the pressing plate are all fixedly mounted on the cutter shaft. The filling plate is located between the base plate and the pressing plate. The base plate has three cutting grooves in its circumferential direction. The filling plate has three mounting holes corresponding to the three cutting grooves in its circumferential direction. The cutting blade is installed in the corresponding cutting grooves and mounting holes.

[0007] Preferably, the chassis, filling disc, and pressure disc are assembled by a plurality of evenly distributed first screws.

[0008] Preferably, the blade groove is provided with multiple threaded holes, and the blade and the pressure plate are provided with reserved holes corresponding to the threaded holes. The blade is assembled by passing through the corresponding reserved holes with a second screw.

[0009] Preferably, a pair of limiting components for limiting the cutter shaft are fixedly installed on the top of the frame. The limiting components include a limiting seat fixed to the top of the frame, a bearing is installed in the limiting seat, and the cutter shaft is installed in the bearing.

[0010] Preferably, a motor is installed at the bottom of the frame, a small pulley is fixed at the output end of the motor, a large pulley is fixed at the rear end of the cutter shaft, and a belt is sleeved between the small pulley and the large pulley.

[0011] The beneficial effects of this utility model are as follows: 1. This equipment only requires manual feeding of branches into the feed inlet to complete the automatic cutting, eliminating the need for manual sawing, greatly reducing manual intervention and significantly improving cutting efficiency; at the same time, it avoids raw material waste, makes full use of all branches, and reduces raw material loss and labor costs in large-scale mushroom cultivation.

[0012] 2. The equipment features a design where the blade shaft drives the blade and the bottom pad of the feed inlet to work together. When the blade rotates, it forms a stable cutting action with the pad. Compared to the randomness of manual cutting, this design ensures that the branch segments are cut to a uniform length, providing uniform wood fiber raw materials for the subsequent production of mushroom culture medium. This improves the stability of the culture medium quality and meets the requirements of large-scale mushroom cultivation for consistent raw materials.

[0013] 3. Convenient blade installation: The three blades can be detached and installed via an assembly plate (base plate, filling plate, and pressure plate). The base plate has a blade groove, and the filling plate has a corresponding installation port. The blades are fixed by passing a second screw through the reserved hole and the threaded hole in the blade groove, which facilitates the disassembly, replacement, and maintenance of the blades and reduces equipment maintenance costs.

[0014] 4. Stable assembly structure: The chassis, filling plate, and pressure plate are assembled with evenly distributed first screws to ensure that the blades are firmly installed, avoid cutting failures caused by loose blades during cutting, and improve the stability of equipment operation.

[0017] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0018] Reference Figure 1-7 A tree branch cutting machine includes a frame 1, a cover 2 installed on the top of the frame 1, a cutter shaft 6 rotatably connected inside the cover 2, an assembly plate installed at the front end of the cutter shaft 6, three blades 13 detachably installed on the circumference of the assembly plate, a feed port 8 provided on the front side of the cover 2, a gasket 11 that mates with the blades 13 fixed at the bottom of the feed port 8, and a discharge channel 4 connected to the bottom of the cover 2.

[0019] Specifically, the assembly plate includes a base plate 12, a filling plate 14, and a pressing plate 20. The base plate 12, the filling plate 14, and the pressing plate 20 are all fixedly mounted on the cutter shaft 6. The filling plate 14 is located between the base plate 12 and the pressing plate 20. The base plate 12 has three cutting grooves 15 in the circumferential direction. The filling plate 14 has three mounting holes 19 corresponding to the three cutting grooves 15 in the circumferential direction. The blades 13 are installed in the corresponding cutting grooves 15 and mounting holes 19 to form a stable blade mounting base.

[0020] The chassis 12, filling plate 14 and pressure plate 20 are assembled by multiple evenly distributed first screws 16 to ensure that the blade is firmly installed, avoid cutting failure caused by the blade loosening during cutting, and improve the stability of equipment operation.

[0021] The blade groove 15 is provided with multiple threaded holes 18, and the blade 13 and the pressure plate 20 are provided with reserved holes 21 corresponding to the threaded holes 18. The blade 13 is assembled by passing the second screw 17 through the corresponding reserved hole 21, which facilitates the disassembly, replacement and maintenance of the blade 13 and reduces the equipment maintenance cost.

[0022] A pair of limiting components for limiting the cutter shaft 6 are fixedly installed on the top of the frame 1. The limiting components include a limiting seat 5 fixed on the top of the frame 1, a bearing 7 installed in the limiting seat 5, and the cutter shaft 6 installed in the bearing 7. Through the rolling friction characteristics of the bearing 7, the frictional resistance of the cutter shaft 6 when rotating is reduced, and the radial displacement of the cutter shaft 6 is limited by the cooperation between the limiting seat 5 and the bearing 7, so as to ensure that the cutter shaft 6 always rotates stably along the fixed axis.

[0023] A motor 3 is mounted at the bottom of the frame 1. A small pulley 9 is fixed to the output end of the motor 3, and a large pulley 10 is fixed to the rear end of the cutter shaft 6. A belt is fitted between the small pulley 9 and the large pulley 10. When the motor 3 starts, the small pulley 9 fixed to its output end rotates accordingly. Through the belt fitted between the small pulley 9 and the large pulley 10 fixed to the rear end of the cutter shaft 6, the motor power is transmitted to the cutter shaft 6, driving the cutter shaft 6 to rotate synchronously (the belt drive can achieve speed matching to meet the cutting torque requirements).

[0024] To prevent the cutting shaft 6 from shifting or wobbling during rotation, affecting cutting accuracy, a pair of limiting components are fixedly installed on the top of the frame 1. These limiting components include a limiting seat 5 fixed to the top of the frame 1, with a bearing 7 installed inside the limiting seat 5. The cutting shaft 6 passes through and is fixed within the bearing 7. The rolling friction characteristics of the bearing 7 reduce the frictional resistance of the cutting shaft 6 during rotation, and the cooperation between the limiting seat 5 and the bearing 7 restricts the radial displacement of the cutting shaft 6, ensuring that the cutting shaft 6 always rotates stably along a fixed axis.

[0025] An assembly plate (consisting of a base plate 12, a filling plate 14, and a pressure plate 20) is installed at the front end of the cutter shaft 6. The three components are tightly assembled and fixed to the cutter shaft 6 by a plurality of evenly distributed first screws 16, forming a stable blade mounting base. Three blades 13 are detachably installed on the circumference of the assembly plate. The specific installation method is as follows: the base plate 12 has three cutting grooves 15 on its circumference, and the filling plate 14 has three mounting holes 19 on its circumference corresponding to the cutting grooves 15. The blades 13 are embedded in the corresponding cutting grooves 15 and mounting holes 19. Then, the second screws 17 pass through the reserved holes 21 on the blades 13 and the pressure plate 20 and are screwed into the threaded holes 18 in the cutting grooves 15 to ensure that the blades 13 are installed firmly and without loosening.

[0026] When the cutter shaft 6 drives the assembly plate and the blade 13 to rotate at high speed, the operator feeds the branches into the feed port 8 on the front side of the machine cover 2. Since the bottom of the feed port 8 is fixed with a pad 11 that cooperates with the blade 13, the rotating blade 13 and the stationary pad 11 form a "moving blade-fixed blade" cutting cooperation, which quickly cuts the fed branches. Moreover, the blade 13 rotates at a uniform speed with the cutter shaft 6, which can ensure that the cutting length of each branch is uniform and consistent, which is suitable for the requirements of mushroom culture medium for raw material specifications.

[0027] After the branches are cut, they fall into the discharge channel 4 connected to the bottom of the machine cover 2 under the action of gravity, and are transported to the designated collection area by the guiding action of the discharge channel 4, thus completing the entire cutting process.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
