Description

Technical Field

[0001] This invention belongs to the field of leaf crushing devices, and specifically relates to a sugarcane leaf dust removal and cutting machine. Background Technology

[0002] Sugarcane is a cash crop widely cultivated in southwestern my country. During its cultivation, in order to improve ventilation and light penetration, reduce pests, enhance lodging resistance, and promote growth, the yellow leaves at the bottom of the sugarcane are peeled off. The fallen leaves are first collected in the field, and after the sugarcane is harvested, the fallen leaves are collected and mixed with the leaves cut off from the top of the sugarcane and chopped up for use as silage, granulation into fertilizer or feed, or as industrial fuel and other industrial raw materials.

[0003] Sugarcane leaves, after being harvested in the field, are usually mixed with a lot of dust and are of varying lengths and in a disorderly manner. The existing methods of chopping sugarcane leaves usually involve directly cutting the leaves with a leaf shredder or a chopper. During the cutting process, a large number of particles float in the air, which not only causes great harm to construction workers and the construction environment, but also makes it impossible to recycle the fine floating particles and flying debris, resulting in a certain degree of resource waste.

[0004] Patent document with application number "CN202111597860.4" discloses a production system and method for sugarcane leaf organic fertilizer, including a crusher. The production system also includes a collection device, a negative pressure transfer device for feeding the crushed sugarcane leaf powder into the collection device under negative pressure, a screening device for screening the sugarcane leaf powder discharged from the collection device, a first screening material conveying device for transferring the screened material to the silo, a stirring device for mixing the screened material from the silo with the fermentation liquid, and a mixed material conveying device for conveying the mixed material to the fermentation pile. Although this device can collect large pieces of debris under negative pressure, which can prevent dust to a certain extent, the process of conveying and screening by vibrating screen and conveyor belt after collection still generates a large amount of smoke and dust. Moreover, the device cannot capture and recycle fine particulate matter in the smoke and dust. In addition, the device has many components and occupies a large space, which will cause a significant increase in cost.

The inlet end of the water pump assembly is connected to one end of two first inlet pipes through a first tee pipe, and the outlet end of the water pump assembly is connected to one end of two first outlet pipes through a second tee pipe. A first solenoid valve is connected to the first inlet pipe, and a second solenoid valve is connected to the first outlet pipe. The number of the chopping machine, the negative pressure fan, the vacuum feed pipe, and the particle capture tank are all two. A second inlet pipe and a second outlet pipe are provided on the side of the particle capture tank. The second inlet pipe is close to the top of the particle capture tank, and the second outlet pipe is close to the top of the settling groove. The second outlet pipe is connected to the other end of the first inlet pipe, and the second inlet pipe is connected to the other end of the first outlet pipe.

[0017] Compared with existing technologies, the present invention has the following advantages: 1. The sugarcane leaf dust removal and cutting machine of the present invention connects the discharge port of the chopper to the second inlet of the vacuum feed pipe. The vacuum feed pipe conveys the broken leaves to the second discharge port through the first spiral conveying rod. The negative pressure fan can simultaneously create a negative pressure environment for the vacuum feed pipe and the chopper chamber of the chopper, thereby collecting floating particulate matter. The particulate matter is then introduced into the capture tank through the exhaust pipe, where it is captured and collected by the liquid in the tank. This not only prevents environmental pollution but also allows for the recycling and reuse of floating particles, reducing resource waste.

[0018] 2. In this invention, a sleeve is provided inside the first cavity, and a first spiral conveying rod is installed inside the sleeve and has mesh openings. The distribution area of ​​the mesh openings corresponds to the connection between the second feed inlet and the exhaust pipe. A second cavity is also provided below the first cavity and communicates with it. A second spiral conveying rod is installed in the second cavity. During operation, small particles of dust in the first and second cavities can pass through the mesh openings and be drawn away by the vacuum fan. At the same time, the mesh openings can also screen large and small broken leaves. Large broken leaves can be discharged from the second discharge port, and small and medium broken leaves can be discharged from the third discharge port. Furthermore, the first and second spiral conveying rods, in conjunction with appropriate airflow, can continuously stir the blades in the first and second cavities, making the screening and dust removal effect more thorough, and also serving as a conveying and guiding function.

[0019] 3. The blade edges of the first and second spiral conveying rods in this invention are made of flexible material, preferably silicone material, which can abut against the inner wall of the sleeve and the inner wall of the second cavity and produce slight deformation. When the broken blades travel out of the area of ​​the mesh and the third feed inlet, the edge of the spiral blades can play a certain sealing role with the pipe wall, thereby reducing part of the negative pressure air volume and making it easier for the large and small broken blades after screening to fall off.

[0020] 4. The present invention includes two chaff cutter, two negative pressure fan, two vacuum feed pipe, and two particle capture tanks, allowing simultaneous operation at two workstations, thus significantly improving work efficiency. Furthermore, a water exchange system is provided, consisting of two first outlet pipes and two first inlet pipes, along with independently controllable first and second solenoid valves. By controlling the opening and closing of these solenoid valves, water can be transferred from one tank to the other while collecting sediment from the other, saving water resources, preventing sediment loss, and ensuring the normal operation of the other equipment.

[0032] More in detail, such as Figure 2As shown, the chopping machine 100 includes a chopping chamber 130, a first feed inlet 110 located at the top of the chopping chamber 130, and a first discharge outlet 120 located at the bottom of the chopping chamber 130. A winding roller 140, a chopping cutter roller 150, and a shredding roller 160 are sequentially installed between the first feed inlet 110 and the first discharge outlet 120. A feeding conveyor belt 170 is installed below the first feed inlet 110. An openable cover 180 is installed on the top of the chopping chamber 130. The cover 180 is located between the first feed inlet 110 and the first discharge outlet 120. When the cover 180 is closed, the interior of the chopping chamber 130 is sealed.

[0033] More in detail, such as Figure 4 As shown, a sandwich cavity 351 is provided between the outer wall of the sleeve 350 and the inner wall of the first cavity 330. A spacer 352 is provided within the sandwich cavity 351. The spacer 352 is welded to the outer wall of the sleeve 350 and the inner wall of the first cavity 330 to support the sleeve 350 and also to separate the upper and lower parts of the sleeve 350. Mesh holes 353 are formed on the wall of the sleeve 350, and the distribution area of ​​the mesh holes 353 corresponds to the connection point between the second feed inlet 310 and the exhaust pipe 210. A second cavity 360 is also formed inside the vacuum guide pipe 300. The axis of the second cavity 360 is parallel to the axis of the first cavity 330. The second cavity 360 is located below the first cavity 330, and the top of the second cavity 360 has a section that connects to the bottom of the first cavity 330.

[0034] like Figure 5 As shown, the ventilated seat 410 has a seat cavity 411 inside. The top and bottom of the seat cavity 411 pass through the top and bottom of the ventilated seat 410. A filter cotton block 412 is installed inside the seat cavity 411. A baffle 413 is installed horizontally at the top opening of the seat cavity 411 to reinforce the filter cotton block 412 inside the seat cavity 411. The function of the filter cotton block 412 is to further absorb the small amount of suspended particles that are not captured, and prevent air pollution.

[0035] Next, the working principle of a sugarcane leaf dust removal and cutting machine in this embodiment will be described in detail to enable those skilled in the art to better understand the present invention: The collected sugarcane leaves are fed into the feeding conveyor belt 170 through the first feed inlet 110. The feeding conveyor belt 170 transports the sugarcane leaves to the winding roller 140, where the leaves are wound in. Then, the long leaves are segmented by the chopping cutter roller 150, and then shredded by the shredding cutter roller 160. After the negative pressure air compressor is turned on, a negative pressure is formed in the interlayer cavity 351 of the vacuum guide pipe 300 and the chopping chamber 130. When the first spiral conveyor rod 340 pushes the shredded leaves through the sleeve 350, the negative pressure airflow can screen the shredded leaves, so that large and medium-sized shredded leaves remain in the sleeve 350 and continue to be pushed, while small shredded leaves fall into the second tube cavity 36. Within 0, the micro-particles are conveyed by the second spiral conveyor rod 370. Due to their light weight, they can be drawn out by negative pressure into the exhaust pipe 210 and sent into the particle capture water tank 400 along with the airflow. The particle capture water tank 400 is filled with clean water or other solutions. The airflow containing particles is introduced into the lower position of the solution through the negative pressure fan 200 and the exhaust pipe 220. Since water molecules have the characteristic of capturing particles, the suspended particles can be locked in the solution and can settle after the airflow is stopped. The particles settle into the settling groove 420. The negative pressure exhaust force can be precisely coordinated and adjusted by adjusting the butterfly valve 230 in the exhaust pipe 210 and the speed of the negative pressure fan 200.

[0036] When it is necessary to collect sediment in one of the particle capture tanks 400, the water pump of the water exchange system 500 is turned on, opening the first solenoid valve 560 corresponding to the particle capture tank 400 and the second solenoid valve 570 corresponding to the other particle capture tank 400. At this time, the liquid can be pumped from the top of the settling tank to the other particle capture tank 400. Then, all solenoid valves are closed, and the cover at the sludge discharge port 430 of the tank is opened to discharge and collect the sediment and a small amount of solution. After collection, the cover is closed again, and the water pump, the second solenoid valve 570 corresponding to the particle capture tank 400 and the first solenoid valve 560 corresponding to the other particle capture tank 400 are turned on. At this time, the solution in the other particle capture tank 400 can be returned, and the other particle capture tank 400 is emptied to carry out the collection work. The collection of sediment will not affect the operation of the leaf.

[0037] In summary, the sugarcane leaf dust removal and cutting machine in this embodiment connects the discharge port of the chopper 100 to the second inlet 310 of the vacuum feed pipe 300. The vacuum feed pipe 300 conveys shredded leaves to the second discharge port 320 through the first spiral conveying rod 340. The negative pressure fan 200 can simultaneously create a negative pressure environment for both the vacuum feed pipe 300 and the chopper chamber 130 of the chopper 100, thereby collecting floating particulate matter. The waste is then introduced into the capture tank through the exhaust pipe 220, where the liquid in the tank captures and collects the floating particles. This not only prevents environmental pollution but also allows for the recycling and reuse of floating particles, reducing resource waste.
