Description

Technical Field

[0001] The present invention relates to the technical field of kitchen waste treatment, and specifically to a combined cutting tool for kitchen waste crushing. Background Art

[0002] Kitchen waste contains both soft waste such as fruit peels and vegetable leaves, and hard substances such as fish bones and meat bones. In the household kitchen waste treatment scenario, the common method is to use high-speed cutting and crushing and then discharge it through the sewer. In recent years, a low-speed treatment method has emerged. Without using large-scale crushing equipment or high-speed crushing devices with excessive noise, most adopt a low-speed repeated cutting and grinding method to crush it, supplemented by heating and drying and then collecting it, or using biological fermentation, etc. The residue can be used as plant fertilizer and is suitable for use in the home environment. The cutting tools used in such equipment usually include one or several groups of moving blades and fixed blades. When the kitchen waste enters the gap between the moving and fixed blades moving relative to each other, the waste block is cut off.

[0003] The comparative document with the publication number ZL201621067341.1 discloses a cutting tool and a waste treatment machine including the cutting tool, which includes a material barrel, a fixed blade, a moving blade, and a rotating shaft. The fixed blade is fixed on the inner side wall of the material barrel, and a through hole is opened at the center of the bottom of the material barrel. The rotating shaft passes through the central hole at the bottom of the material barrel and is connected to the power output device. After the moving blade is connected to the rotating shaft, it can make a rotational movement. Its characteristics are that there is a gap between the fixed blade and the moving blade in the axial direction of the rotating shaft; tooth-shaped strips or protrusions are provided on the upper and lower opposite surfaces of the fixed blade and the moving blade. This cutting tool is used to cut and grind kitchen waste blocks of different sizes in the material barrel into finer debris. This cutting tool is applied to a kitchen waste treatment machine, and the motor outputs torque to the moving blade through a gearbox, driving the moving blade to rotate and cooperate with the fixed blade to cut and crush the waste, and an overload reverse and forced stop function is set. During the treatment process, the kitchen waste is heated and dried, and finally the kitchen waste is converted into small granular dry substances, which can be used for plant fertilizers, etc.

[0004] However, the following disadvantages exist in the prior art. Since the fixed blade is installed on the barrel wall, the cutting part is limited to the far end of the power output axis center, resulting in a small cutting force and inconvenient adjustment when the power output torque is certain. It is difficult to crush harder waste blocks, especially when encountering hard ones such as pig bones and cow bones, the cutting tool is often stuck, causing the motor to be overloaded and damaged, or forced to stop forcibly, aborting the cutting and grinding, and failing to achieve the use effect; during the treatment of some kitchen waste, it adheres and solidifies on the barrel wall, resulting in difficult cleaning and even damage to the cutting tool. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a combined cutting tool for kitchen waste crushing with smooth cutting.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A combined kitchen waste crushing tool, comprising a material barrel, a cutting assembly, a fixed blade and a bottom cut; the fixed blade is fixed at the inner bottom of the material barrel; the cutting assembly includes a moving blade; a rotatable rotating assembly is installed at the inner bottom of the material barrel; the rotating assembly rotates around the axis of the material barrel; the moving blade is fixed on the lower half of the rotating assembly; and the moving blade is arranged above the fixed blade; at least one side of the fixed blade is provided with a bottom cut with a blade portion facing the blade edge of the moving blade; one end of the bottom cut extends towards the center of the bottom of the material barrel.

[0007] The moving blade performs a shearing motion towards the bottom cut, cutting off a small section of the waste block in the bottom cut. After repeating this process multiple times, the larger waste block is crushed; when the waste block is relatively hard, under the extrusion of the moving blade, the waste block slides along the edge line of the bottom cut towards the center position, the shearing force arm gradually decreases and the shearing force correspondingly increases. When it slides to an appropriate position, the waste block is cut off; after repeating in the above manner for a certain period of time, all the waste in the material barrel is crushed into fine particles, the moving blade stops rotating, and the finely crushed residues are poured out, and the processing process ends; by setting the moving blade and the bottom cut with one end extending towards the center of the bottom of the material barrel; the shearing force arm and shearing force of the moving blade on the waste block can be changed, and waste blocks of different hardnesses can be cut, significantly improving the performance; at the same time, when the waste block slides along the blade edge of the bottom cut, the shearing force between the moving blade and the bottom cut gradually increases, effectively avoiding the problem of frequent tool jamming and tool damage caused by the constant shearing force during the cutting process, which is insufficient to cut waste blocks of higher hardness, reducing manual intervention, and making the processing process smoother and more effective.

[0008] Preferably, one side of the bottom cut is arc-shaped and the center of curvature is close to the blade edge of the moving blade.

[0009] Preferably, a sweeping plate that fits the inner wall of the material barrel is fixed on the side of the moving blade close to the barrel wall of the material barrel.

[0010] When the moving blade is working, it drives the sweeping plate to move relative to the inner wall of the barrel, scraping off the residues on the inner wall of the barrel.

[0011] Preferably, the rotating assembly includes a central sleeve, a locking bolt, a central shaft, a conical top, an outer connecting sleeve and a cover plate; a vertically penetrating central sleeve extends upwards from the center of the bottom of the material barrel; an outer connecting sleeve is sleeved outside the central sleeve; a conical top integrally formed is fixed at the top of the outer connecting sleeve; a central shaft is inserted into the central sleeve from the bottom towards the top inside the central sleeve; the upper section of the central shaft is threadedly connected to the inner opening at the top of the central sleeve; the central shaft passes through the top opening of the central sleeve and is inserted into the conical top; a locking bolt passes through the center of the central shaft; one end of the locking bolt is threadedly connected to the inner bottom of the conical top.

[0012] Preferably, the bottom end of the central shaft extends downward beyond the bottom end of the barrel body; and the bottom end of the central shaft is drivingly connected to the motor through a coupling; a torque sensor is installed on the output shaft of the motor; the signal output end of the torque sensor is electrically connected to the signal input end of the PLC controller; the signal output end of the PLC controller is electrically connected to the motor.

[0013] Preferably, from the end connected to the outer connecting sleeve to the other end, the outer diameter of the conical top gradually decreases until the other end of the conical top is a tip.

[0014] Preferably, a square positioning hole is formed at the bottom of the conical top; a square positioning block is fixed at one end of the central shaft facing the conical top; the positioning block is clamped in cooperation with the positioning hole.

[0015] Preferably, a locking bolt hole is formed on the central side of the positioning hole facing the tip of the conical top; the end of the locking bolt is inserted into the locking bolt hole.

[0016] Preferably, a weight reduction groove is formed at the bottom of the moving blade. The quality of the moving blade is reduced, thereby reducing the load on the motor and saving the power required by the motor.

[0017] Preferably, there are two groups of moving blades, which are arranged up and down respectively, and both groups of moving blades are welded on the outside of the rotating assembly. There are two groups of fixed blades, and they are arranged at intervals up and down with the two groups of moving blades. The lowermost fixed blade is located below the lowermost moving blade. Both groups of fixed blades are fixed on the barrel wall of the material barrel.

[0018] The two groups of moving blades and fixed blades provided improve the cutting and crushing effect.

[0019] Put the outer connecting sleeve fixedly connected to the moving blade on the central sleeve, and make the positioning hole at the bottom of the cone top fit with the positioning block at the top end of the central shaft. Then, screw the locking bolt upward from the bottom end of the central shaft. The bottom end of the central shaft is connected to the motor. Put the kitchen waste in various forms such as fruit peels, vegetable leaves, leftovers, and bones into the material bucket. When starting to work, the motor drives the central shaft to rotate, and the central shaft drives the outer connecting sleeve and the moving blade connected externally to rotate. According to the physical formula "torque = force arm × force", the shearing force given by the moving blade to the garbage block is the torque of the power output divided by the force arm at the position where the garbage block contacts the cutting edge of the moving blade. When the outer connecting sleeve rotates to make the moving blade approach the barrel wall end of the bottom cut, the cutting edge of the moving blade and the bottom cut start to approach, forming a shearing area a. The garbage block falling into the shearing area a is sheared, and its shearing force arm is L1. Garbage blocks such as fruit peels and vegetable leaves have a lower hardness. Each shearing movement between the moving blade and the bottom cut can cut off a small section of such garbage blocks. After repeating many times, the larger garbage blocks are crushed; when the hardness of the garbage block is higher, a greater shearing force is required for cutting. When the garbage block cannot be cut in the shearing area a, under the extrusion of the moving blade, the garbage block slides along the arc of the bottom cut towards the central position, the shearing force arm gradually decreases, and the shearing force increases accordingly. When it slides to an appropriate position, the garbage block is cut off. And harder garbage blocks will not be cut until they slide to the shearing area b where the shearing force arm is the smallest L2 and obtain the maximum shearing force to be cut off; during the process of the garbage block sliding along the bottom cut, the garbage that has left the shearing area continues to rotate, roll, etc. in the material bucket under the push of other garbage. When it enters another shearing area next time, the entry angle of the garbage block changes, and it tries to be sheared again. After repeating many times, it is cut off; after repeating in the above manner for a certain period of time, all the garbage in the material bucket is crushed into fine particles. The moving blade stops rotating, and the fine residue is poured out, and the treatment process ends; through the adaptive adjustment of the shearing force arm and the shearing force, harder garbage blocks can be cut, significantly improving the use performance; effectively avoiding frequent tool jamming and tool damage during the cutting process, reducing manual intervention, making the treatment process smoother and with better results; increasing the length of the cutting working section, enabling more garbage to be cut simultaneously, and improving the cutting and crushing efficiency; setting the bottom cut integrated with the material bucket, reducing the number of parts and the manufacturing and installation processes, and saving costs;

[0020] When the garbage block with high hardness reaches the shearing area b and still cannot be cut off when the shearing force is the largest, or it is further jammed during the sliding towards the center and cannot continue to slide, the torque sensor on the output shaft of the motor will sense the overload, and through the PLC controller, it will force the moving blade to stop rotating and instead rotate in the reverse direction first, trying to separate the garbage block from the cut, and enter a new cycle in a way of changing the angle again, or stop the machine and wait for other treatment methods, so as not to be damaged due to forcibly rotating the moving blade continuously.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] A. By providing a moving blade and a bottom cutout whose one end extends towards the center of the bottom of the material bucket, the shear force arm and shear force of the moving blade on the garbage block are changed, so that garbage blocks with different hardnesses can be cut, significantly improving the service performance;

[0023] Meanwhile, when the garbage block slides along the edge of the bottom cutout, the shear force between the moving blade and the bottom cutout gradually increases, effectively avoiding the problems of frequent tool jamming and tool damage caused by the unchanged shear force during the cutting process, which is insufficient to cut garbage blocks with higher hardness, reducing manual intervention, and making the processing process smoother and more effective;

[0024] B. The provided arc-shaped bottom cutout increases the length of the cutting working section, enabling more garbage to be cut simultaneously and improving the cutting and crushing efficiency;

[0025] By providing a sweeping plate, when the moving blade is working, it drives the sweeping plate to move relative to the inner wall of the bucket body, scraping off the residues on the inner wall of the bucket body;

[0026] The integration of the provided bottom cutout and the material bucket reduces the number of components and the manufacturing and installation processes, saving costs;

[0027] When the torque sensor senses that the output shaft of the motor is overloaded, the PLC controller forcibly stops the continuous rotation of the moving blade, instead rotating in the reverse direction first, attempting to separate the garbage block from the cutout, entering a new cycle in a changed angle manner, or stopping the machine and waiting for other processing methods, so as not to be damaged due to forcibly rotating the moving blade continuously, improving the protection of the equipment;

[0028] A weight reduction groove is provided at the bottom of the moving blade; the mass of the moving blade is reduced, thereby reducing the load on the motor and saving the electricity required by the motor;

[0029] The provided two groups of moving blades and fixed blades improve the cutting and crushing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Embodiment 1

[0041] Refer to Figure 1 , this embodiment discloses a kitchen waste crushing combined cutter, including a material barrel 1, a rotating assembly 2, a cutting assembly 3, a fixed blade 4 and a bottom notch 5.

[0042] The material barrel 1 includes a barrel body 11, a flanging 12 and support feet 13. The opening of the barrel body 11 is bent outwards to form a flanging 12. Three support feet 13 distributed around the central axis of the barrel body 11 are installed at the bottom of the barrel body 11.

[0043] Refer to Figure 4 and Figure 5 , the cutting assembly 3 includes a moving blade 31. The moving blade 31 is welded outside the outer connecting sleeve 25. And the moving blade 31 is arranged 2 - 3 cm above the fixed blade 4. The cutting edge of the moving blade 31 faces the arc-shaped edge part of the bottom notch 5, and the cutting edge of the moving blade 31 makes a shearing movement relative to the edge part of the bottom notch 5 to cut off the garbage mass clamped between the two edges.

[0044] The fixed blade 4 with the same inner diameter as the barrel body 11 is welded to the inner bottom of the barrel body 11. At least one bottom notch 5 is formed on the fixed blade 4, one side of which has a blade part and faces the blade edge of the moving blade 31; one end of the bottom notch 5 extends towards the center of the bottom of the material barrel 1.

[0045] One side of the bottom notch 5 is arc-shaped and the center of curvature is close to the blade part of the moving blade 31. The arc-shaped bottom notch 5 increases the length of the cutting working section, enabling more garbage to be cut simultaneously and improving the cutting and crushing efficiency.

[0046] Refer to Figure 4 and Figure 5 As shown in

[0047] Refer to Figure 2 and Figure 3 As shown in

[0048] The bottom end of the central shaft 23 extends downward beyond the bottom end of the barrel body 11. And the bottom end of the central shaft 23 is connected to the motor through a coupling.

[0049] A torque sensor is installed on the output shaft of the motor. The signal output end of the torque sensor is electrically connected to the signal input end of the PLC controller. The signal output end of the PLC controller is electrically connected to the motor.

[0050] From the end connected to the outer connecting sleeve 25 to the other end, the outer diameter of the conical top 24 gradually decreases until the other end of the conical top 24 is a tip.

[0051] A square positioning hole 241 is formed at the bottom of the conical top 24. A square positioning block is welded to the end of the central shaft 23 facing the conical top 24. The positioning block is clamped with the positioning hole 241 in a matching manner.

[0052] The locking bolt hole 221 is formed on the central side of the positioning hole 241 facing the tip of the conical top 24. The end of the locking bolt 22 is inserted into the locking bolt hole 221.

[0053] A washer is sleeved between the top end of the central sleeve 21 and the outer connection sleeve 25.

[0054] A weight reduction groove 33 is formed at the bottom of the moving blade 31.

[0055] The mass of the moving blade 31 is reduced, thereby reducing the load on the motor and saving the power required by the motor.

[0056] The working principle of this embodiment is as follows: The outer connection sleeve 25 fixedly connected to the moving blade 31 is sleeved on the central sleeve 21, and the positioning hole 241 at the bottom of the conical top 24 is fitted with the positioning block at the top end of the central shaft 23. Then, the locking bolt 22 is screwed upward from the bottom end of the central shaft 23. The bottom end of the central shaft 23 is connected to the motor. Put the kitchen waste in various forms such as fruit peels, vegetable leaves, leftovers, and bones into the material bucket 1. When starting to work, the motor drives the central shaft 23 to rotate, and the central shaft 23 drives the outer connection sleeve 25 and the moving blade 31 connected to its outside to rotate. According to the physical formula "moment = force arm × force", the shearing force given by the moving blade 31 to the garbage block is the moment of the power output divided by the force arm at the position where the garbage block contacts the cutting edge of the moving blade 31. When the outer connection sleeve 25 rotates to make the moving blade 31 approach the barrel wall end of the bottom cutting edge 5, the cutting edge of the moving blade 31 and the bottom cutting edge 5 start to approach, forming a shearing area a as shown in the attachment. Figure 6 The garbage blocks falling into the shearing area a are sheared, and the shearing force arm is L1. The garbage blocks such as fruit peels and vegetable leaves have a lower hardness. Each shearing movement between the moving blade 31 and the bottom cutting edge 5 can cut off a small section of such garbage blocks. After repeated operations, the larger garbage blocks will be crushed. When the hardness of the garbage block is higher, a greater shearing force is required for cutting. When the garbage block cannot be cut in the shearing area a, under the extrusion of the moving blade 31, the garbage block slides along the arc of the bottom cutting edge 5 towards the central position. The shearing force arm gradually decreases and the shearing force increases accordingly. When it slides to an appropriate position, the garbage block is cut off. And the harder garbage blocks will not be cut until they slide to the position as shown in the attachment. Figure 6The shearing area b where the shearing force arm L2 is the smallest as shown is obtained, and the largest shearing force is used to cut it off; during the process of the garbage block sliding along the bottom cut 5, the garbage that has left the shearing area continues to rotate, tumble, etc. in the material bucket 1 under the push of the moving blade 31 together with other garbage. When it enters another shearing area next time, the entry angle of this garbage block changes and it tries to be sheared again. After repeating many times, it is cut off; after repeating in the above manner for a certain period of time, all the garbage in the material bucket 1 is crushed into fine particles, the moving blade 31 stops rotating, and the fine residues are poured out, and the treatment process ends; through the adaptive adjustment of the shearing force arm and the shearing force, harder garbage blocks can be cut, significantly improving the performance; effectively avoiding frequent tool jamming and tool damage during the cutting process, reducing manual intervention, making the treatment process smoother and with better results; increasing the length of the cutting working section, enabling more garbage to be cut simultaneously, and improving the cutting and crushing efficiency; the bottom cut 5 and the material bucket 1 are integrated, reducing the number of components and the manufacturing and installation processes, and saving costs.

[0057] When a garbage block with high hardness reaches the shearing area b and still cannot be cut off when the shearing force is the largest, or it is further jammed during the sliding process towards the center and cannot continue to slide, the torque sensor on the output shaft of the motor will sense the overload, and the PLC controller will force the moving blade 31 to stop rotating. Instead, it will first rotate in the reverse direction, try to separate the garbage block from the cut, and enter a new cycle in a way of changing the angle again, or stop the machine and wait for other treatment methods, so as not to be damaged due to forcing the moving blade 31 to continue rotating.

[0058] Embodiment 2

[0059] Different from Embodiment 1, there are two groups of moving blades 31, which are arranged up and down respectively, and both groups of moving blades 31 are welded to the outside of the outer connecting sleeve 25. There are two groups of fixed blades 4, and they are arranged at intervals up and down with the two groups of moving blades 31. The lowermost fixed blade 4 is located below the lowermost moving blade 31. Both groups of fixed blades 4 are fixed on the barrel wall of the material bucket 1.
