Abstract
Description
Technical Field
[0001] This invention relates to the field of environmental protection equipment technology, and in particular to a material handling machine. Background Technology
[0002] In dairy farms, bedding is typically laid on the ground to improve the comfort of cows' bedding and increase milk production. Bedding materials generally include sand, rice husks, straw, sawdust, rubber mats, and dried cow dung. Among these, dried cow dung is a popular choice because it can be sourced locally and reused, reducing production costs for farms.
[0003] Because feces contain a large amount of water, a material processing machine is needed for solid-liquid separation. Existing material processing machines typically use a screw extrusion method for solid-liquid separation. However, it is difficult to control the pressure on the material during extrusion, making it difficult to control the moisture content after extrusion. Furthermore, uneven force during screw extrusion causes the material to be stretched, leading to fiber breakage and affecting the fiber density, thus reducing its suitability as bedding material. Simultaneously, the high friction between the auger blades and the material during screw extrusion results in energy loss through the conversion of electrical energy into heat, leading to reduced efficiency and increased energy consumption. Therefore, there is an urgent need for a material processing machine that can adjust the moisture content of the extruded material, improve the fiber density, and reduce energy consumption. Summary of the Invention
[0004] In view of the above problems of the prior art, this application provides a material processing machine that can adjust the moisture content of the material after extrusion, improve the fiber content of the material after processing, and reduce the energy consumption of the equipment.
[0005] This application provides a material handling machine, including a feeding hopper, a compression hopper, a discharging hopper, and a drive cylinder; wherein, an auger is provided in the feeding hopper for feeding materials into the compression hopper; the drive cylinder is disposed on the compression hopper, and the drive rod of the drive cylinder extends into the compression hopper for compressing and pushing the materials in the compression hopper into the discharging hopper.
[0006] Using the above structure, the material in the compression chamber is compressed by the drive cylinder and pushed into the discharge chamber. This compression forces water out of the material, achieving solid-liquid separation. Since the compression force is directly provided by the drive cylinder, it can be adjusted to regulate the moisture content of the material after compression. Furthermore, the drive cylinder ensures that the compression force is approximately uniform across different parts of the material, preventing tearing and damage to the fibers. This improves the fiber content of the processed material. Additionally, the direct compression by the drive cylinder reduces friction with the material, thus lowering energy consumption, reducing equipment wear, and lowering operating costs.
[0007] In some embodiments, a first sensor is provided on the drive cylinder, the first sensor being used to detect the position of the drive rod.
[0008] With the above structure, the position of the drive rod is detected by the first sensor, which makes it easy to control the drive rod so that the drive cylinder can control the extension or retraction of the drive rod.
[0009] In some embodiments, the drive cylinder is further provided with a sensor, the sensor is fixedly connected to the drive rod, and the first sensor is disposed on the movement path of the sensor to detect whether the sensor passes the position corresponding to the first sensor.
[0010] With the above structure, the first sensor can determine the length of the extended drive rod by detecting whether the sensing element passes through the corresponding position of the first sensor.
[0011] In some embodiments, multiple first sensors are arranged along the moving path. When the drive rod extends to make the sensing element reach the position corresponding to the first sensor in the middle, the drive cylinder controls the drive rod to reduce the extension speed and increase the extension driving force.
[0012] With the above structure, the longer the drive rod extends during material compression, the greater the degree of material compression and the greater the pressure between the material and the drive rod. Therefore, during the compression process, the speed and power of the drive rod extension can be adjusted according to the pressure between the material and the drive rod, thereby improving equipment efficiency and reducing energy consumption.
[0013] In some embodiments, when the drive rod extends and the sensor reaches the position corresponding to the first sensor among the plurality of first sensors located near one end of the compression chamber, the drive cylinder controls the drive rod to stop; and / or, when the drive rod retracts and the sensor reaches the position corresponding to the first sensor among the plurality of first sensors located away from one end of the compression chamber, the drive cylinder controls the drive rod to stop.
[0014] With the above structure, when the drive rod extends and the sensor reaches the position corresponding to the first sensor located near the end of the compression chamber, the material in the compression chamber is pressed into the discharge chamber. The drive rod extends to a predetermined length, and the drive cylinder stops the drive rod. When the drive rod retracts and the sensor reaches the position corresponding to the first sensor located away from the end of the compression chamber, the drive rod retracts from the compression chamber into the drive cylinder, and the drive cylinder stops the drive rod.
[0015] In some embodiments, after the drive rod extends to bring the sensing element to the position corresponding to the first sensor among the plurality of first sensors located near one end of the compression chamber, the drive rod controls the drive rod to stop at a first time threshold.
[0016] With the above structure, when the sensing element reaches the position corresponding to the first sensor at one end of the high-pressure compression chamber, that is, after the drive rod presses the material in the compression chamber into the discharge chamber, the drive rod is stopped at the first time threshold, so that the material can be kept in a compressed state for the first time threshold, thereby fully squeezing out the moisture in the material.
[0017] In some embodiments, the discharge bin has a discharge port at the end away from the compression bin, and a filter plate is provided on each side of the discharge bin at the end facing the compression bin. One end of the filter plate is hinged to the discharge bin, and the other end extends toward the discharge port. The other ends of the two filter plates are inclined toward each other.
[0018] With the above structure, filter plates are installed on both sides of the discharge hopper facing the compression chamber. This allows moisture in the material to pass through the filter plates and flow out after being pressed into the discharge hopper, achieving solid-liquid separation. Simultaneously, by tilting the other ends of the filter plates towards each other, the space between the two filter plates gradually decreases towards the discharge port, improving the compression effect on the material and thus enhancing solid-liquid separation. It also reduces the thickness of the material as it passes through the space between the two filter plates and exits through the discharge port, facilitating moisture evaporation. Furthermore, since one end of the filter plate is hinged to the discharge hopper, the distance to the other end can be adjusted. This allows for adjustment of the compression effect of the filter plates on the material, thereby regulating the moisture content of the material discharged from the outlet.
[0019] In some embodiments, the compression chamber is cylindrical and further includes a transition chamber, one end of which is circular and communicates with the compression chamber, and the other end of which is square and communicates with the discharge chamber. The two filter plates are respectively located at corresponding positions at the other end of the transition chamber, and the transition chamber is smoothly connected between one end and the other end.
[0020] By adopting the above structure and making the compression chamber cylindrical, the manufacturing difficulty of the compression chamber can be reduced. By incorporating a transition chamber, with one end round and the other square, it is easier for material in the compression chamber to enter the transition chamber. Making the other end of the transition chamber square facilitates material flow between the two filter plates, resulting in more uniform material distribution between the plates. A smooth transition between the two ends of the transition chamber ensures a smoother process for the material to change from a round to a square shape.
[0021] In some embodiments, the material handling machine of this application further includes a buffer chamber, which is disposed above and communicates with the compression chamber, and the feed chamber is communicated with the buffer chamber.
[0022] By adopting the above structure and setting a buffer chamber between the feeding chamber and the compression chamber, a buffer space can be provided for the material supplied from the feeding chamber to the compression chamber. When there is too much material supplied from the feeding chamber, the material can be temporarily stored in the buffer chamber, thereby improving the smoothness of the material handling machine during operation.
[0023] In some embodiments, an overflow port is provided at the upper end of the buffer bin, and a second sensor is provided near the overflow port. The second sensor is used to detect the height of the material in the buffer bin.
[0024] By employing the above structure and placing a second sensor near the overflow outlet, when the second sensor detects that the material in the buffer chamber has reached the corresponding height, the auger can be controlled to stop conveying material into the buffer chamber. This prevents excessive material from overflowing from the overflow outlet, thus avoiding material spillage and environmental pollution.
[0025] In some embodiments, the feed hopper is connected to the buffer hopper at the middle position on the side of the buffer hopper, and the extension direction of the auger is the same as the arrangement direction of the drive cylinder, the compression hopper and the discharge hopper.
[0026] By adopting the above structure, the dimensions of the material handler in the width direction can be reduced, thereby reducing the installation space of the material handler and facilitating its installation.
[0027] In some embodiments, a feed inlet is provided at the top of the feed hopper, and a vibration motor is provided below the feed inlet.
[0028] By adopting the above structure and installing a vibration motor below the feed inlet, the material adhering to the side wall of the feed hopper can be shaken off, thereby improving the efficiency of material conveying in the feed hopper.
[0029] These and other aspects of the invention will become more apparent from the following description of several embodiments. Attached Figure Description

[0040] Hereinafter, with reference to the accompanying drawings, possible embodiments of the material handling machine 10 of this application will be described by way of example.
[0041] Figure 1 This is a three-dimensional structural schematic diagram of the material handling machine 10 in this application; Figure 2 for Figure 1 A side projection schematic diagram of the material handling machine 10; Figure 3 for Figure 1 A schematic diagram of the top structure of the material handling machine 10. (See diagram below.) Figures 1-3 As shown, the material handling machine 10 in this application includes a feeding bin 100, a compression bin 300, a discharge bin 500, and a drive cylinder 600; wherein, the feeding bin 100 is provided with an auger 120 for feeding materials into the compression bin 300; the drive cylinder 600 is provided on the compression bin 300, and the drive rod of the drive cylinder 600 extends into the compression bin 300 for compressing and pushing the materials in the compression bin 300 into the discharge bin 500.
[0042] As described above, the material in the compression chamber 300 can be compressed by the drive cylinder 600 and pushed into the discharge chamber 500. This compression forces water out of the material, achieving solid-liquid separation. Since the extrusion pressure is directly provided by the drive cylinder 600, it can be adjusted to regulate the moisture content of the material after compression. Furthermore, the extrusion pressure applied by the drive cylinder 600 is made approximately uniform across different locations, preventing pulling between materials and thus avoiding damage to the fibers. This improves the fiber content of the processed material. Additionally, the direct compression by the drive cylinder 600 reduces friction between the material and the cylinder. This not only reduces energy consumption but also minimizes equipment wear and reduces operating costs.
[0043] In some embodiments, the drive cylinder 600 may be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder, and there is no limitation thereto.
[0044] In some embodiments, such as Figure 1 , Figure 2 As shown, a first sensor is installed on the drive cylinder 600 to detect the position of the drive rod. Therefore, by detecting the position of the drive rod through the first sensor, the drive rod can be easily controlled, allowing the drive cylinder 600 to extend or retract it.
[0045] In some embodiments, such as Figure 1 , Figure 2 As shown, the drive cylinder 600 is also equipped with a sensor, which is fixedly connected to the drive rod. A first sensor is positioned on the movement path of the sensor to detect whether the sensor passes the position corresponding to the first sensor. Thus, the first sensor can determine the extension length of the drive rod by detecting whether the sensor passes the position corresponding to the first sensor.
[0046] In some embodiments, the first sensor may be a photoelectric switch, a distance sensor, or other sensor capable of detecting the passage of the sensing element.
[0047] In some embodiments, such as Figure 1 , Figure 2As shown, multiple first sensors are arranged along the moving path. When the drive rod extends and the sensing element reaches the position corresponding to the first sensor in the middle, the drive cylinder 600 controls the drive rod to reduce the extension speed and increase the extension driving force. Since the longer the drive rod extends during the material compression process, the greater the degree of material compression and the greater the pressure between the material and the drive rod. Therefore, during the material compression process, the extension speed and force of the drive rod can be adjusted according to the pressure between the material and the drive rod, thereby improving equipment efficiency and reducing energy consumption.
[0048] In some embodiments, when the drive rod extends, causing the sensor to reach the position corresponding to the first sensor among the plurality of first sensors located near the end of the compression chamber 300, the drive cylinder 600 controls the drive rod to stop; and / or, when the drive rod retracts, causing the sensor to reach the position corresponding to the first sensor among the plurality of first sensors located away from the end of the compression chamber 300, the drive cylinder 600 controls the drive rod to stop. Thus, when the drive rod extends, causing the sensor to reach the position corresponding to the first sensor located near the end of the compression chamber 300, the material in the compression chamber 300 is pressed into the discharge chamber 500, the drive rod extends to a predetermined length, and the drive cylinder 600 controls the drive rod to stop. When the drive rod retracts, causing the sensor to reach the position corresponding to the first sensor located away from the end of the compression chamber 300, the drive rod retracts from the compression chamber 300 into the drive cylinder 600, and the drive cylinder 600 controls the drive rod to stop.
[0049] In some embodiments, after the drive rod extends to bring the sensing element to the position corresponding to the first sensor located near the end of the compression chamber 300 among a plurality of first sensors, the drive rod controls the drive rod to stop for a first time threshold. Thus, by stopping the drive rod for a first time threshold when the sensing element reaches the position corresponding to the first sensor located at the end of the compression chamber 300, i.e. after the drive rod has pressed the material in the compression chamber 300 into the discharge chamber 500, the material can be kept in a compressed state for the first time threshold, thereby fully squeezing out the moisture from the material.
[0050] Figure 4 for Figure 3 A partial cross-sectional view of the material handling machine 10. In some embodiments, such as... Figures 1-4As shown, the discharge hopper 500 has a discharge port at the end away from the compression chamber 300. Inside the discharge hopper 500, on both sides facing the compression chamber 300, there is a filter plate 520. One end of the filter plate 520 is hinged to the discharge hopper 500, and the other end extends towards the discharge port. The other ends of the two filter plates 520 are inclined towards each other. Therefore, by placing filter plates 520 on both sides of the discharge hopper 500 facing the compression chamber 300, moisture in the material can pass through the filter plates 520 and flow out after the material is pressed into the discharge hopper 500, thus achieving solid-liquid separation. Simultaneously, by tilting the other ends of the filter plates 520 towards each other, the space between the two filter plates 520 gradually decreases as it approaches the discharge port, thereby improving the compression effect on the material and further enhancing the solid-liquid separation effect. It also reduces the thickness of the material as it passes through the space between the two filter plates 520 and exits through the discharge port, facilitating the evaporation of moisture in the material. Furthermore, since one end of the filter plate 520 is hinged to the discharge hopper 500, the distance to the other end can be adjusted. This allows for adjustment of the compression effect of the filter plate 520 on the material, thereby regulating the moisture content of the material discharged from the outlet.
[0051] In some embodiments, the compression chamber 300 is cylindrical. The material handling machine 10 of this application also includes a transition chamber 400. One end of the transition chamber 400 is circular and communicates with the compression chamber 300, while the other end is square and communicates with the discharge chamber 500. Two filter plates 520 are respectively located at corresponding positions at the other end of the transition chamber 400, and the transition chamber 400 smoothly transitions between its two ends. Therefore, by making the compression chamber 300 cylindrical, the processing difficulty of the compression chamber 300 can be reduced. By setting the transition chamber 400 so that one end is circular and the other end is square, it is easier for material in the compression chamber 300 to enter the transition chamber 400. By making the other end of the transition chamber 400 square, it is easier for material to enter between the two filter plates 520, making the material between the transition plates more uniform. By making the transition chamber 400 smoothly transition between its two ends, the process of material changing from a circular shape to a square shape can be smoother.
[0052] In some embodiments, such as Figures 1-4 As shown, the material handling machine 10 of this application also includes a buffer chamber 200, which is disposed above and communicates with the compression chamber 300. The feed chamber 100 is also communicated with the buffer chamber 200. Therefore, by providing the buffer chamber 200 between the feed chamber 100 and the compression chamber 300, a buffer space can be provided for the material supplied from the feed chamber 100 to the compression chamber 300. When there is an excess of material supplied from the feed chamber 100, the material can be temporarily stored in the buffer chamber 200, thereby improving the smoothness of the material handling machine 10 during operation.
[0053] In some embodiments, such as Figures 1-4 As shown, an overflow port is provided at the upper end of the buffer bin 200. A second sensor 220 is located near the overflow port to detect the height of the material inside the buffer bin 200. Therefore, by placing the second sensor 220 near the overflow port 210, when the second sensor 220 detects that the material in the buffer bin 200 has reached the corresponding height, the auger 120 can be controlled to stop conveying material into the buffer bin 200, thus preventing excessive material from overflowing from the overflow port 210. This prevents material spillage and environmental pollution.
[0054] In some embodiments, such as Figures 1-4 As shown, the feed hopper 100 is connected to the buffer hopper 200 at the middle position on the side of the buffer hopper 200, and the extension direction of the auger 120 is the same as the arrangement direction of the drive cylinder 600, the compression hopper 300 and the discharge hopper 500. This allows for a reduction in the width dimension of the material handler 10, thereby reducing the installation space required and facilitating its installation.
[0055] In some embodiments, such as Figures 1-4 As shown, a feed inlet 110 is provided at the top of the feed hopper 100, and a vibration motor 130 is provided below the feed inlet 110. Therefore, by providing a vibration motor below the feed inlet 110, the material adhering to the side wall of the feed hopper 100 can be shaken off, thereby improving the material conveying efficiency of the feed hopper 100.
[0056] The above content, combined with Figures 1-4 The following describes possible embodiments of the material handling machine 10 in this application. The specific structure of one embodiment of the material handling machine 10 in this application will now be described in detail with reference to the accompanying drawings.
[0057] like Figures 1-4 As shown, the material handling machine 10 in this embodiment is an animal (e.g., dairy cow) bedding material handling machine, including a feeding hopper 100, a buffer hopper 200, a compression hopper 300, a transition hopper 400, a discharge hopper 500, and a drive cylinder 600. The feeding hopper 100 is used to convey material into the compression hopper 300. The buffer hopper 200 is located between the feeding hopper 100 and the compression hopper 300 to provide buffer space for the material. The transition hopper 400 connects the compression hopper 300 and the discharge hopper 500, and the drive cylinder 600 is used to press the material in the compression hopper 300 into the discharge hopper 500 through the transition hopper 400.
[0058] like Figure 1 , Figure 2As shown, a base 310 is provided at the bottom of the compression chamber 300 for mounting and fixing the compression chamber 300 and the material handling machine 10. The compression chamber 300 has a cylindrical cavity extending horizontally inside. A drive cylinder 600 is installed at one end of the compression chamber 300, and a transition chamber 400 and a discharge chamber 500 are installed at the other end. The drive rod of the drive cylinder 600 is arranged along the axis of the cavity inside the compression chamber 300 and extends into the compression chamber 300. A piston is provided at the end of the drive rod, which is adapted to the cavity inside the compression chamber 300 and can move along the axis of the cavity inside the compression chamber 300 under the drive of the drive rod.
[0059] like Figure 1 , Figure 2 As shown, a first sensor 610 and a sensing element 620 are also provided on the drive cylinder 600. The first sensor 610 is fixedly mounted on the housing of the drive cylinder 600, and the sensing element 620 is fixedly connected to the drive rod and positioned at the same location as the first sensor 610. When the drive rod extends or retracts from the drive cylinder 600, the sensing element 620 can pass through the sensing end of the first sensor 610, allowing the first sensor 610 to detect the passage of the sensing element 620.
[0060] like Figure 1 , Figure 2 As shown, three first sensors 610 are arranged along the extension direction of the drive rod. The first sensor 610 located at the end facing the compression chamber 300 is positioned where the sensing element 620 corresponds to the position where the drive rod extends and drives the piston in the cavity of the compression cylinder to a position close to the transition chamber 400 and the discharge chamber 500. When the first sensor 610 detects the sensing element 620, the drive cylinder 600 controls the drive rod to stop extending, allowing the piston to compress the material in the cavity of the compression chamber 300 under the drive of the drive rod. When the piston reaches a position close to the transition chamber 400 and the discharge chamber 500, the piston stops to prevent damage to the piston compression chamber 300 from excessive piston movement. Furthermore, when the first sensor 610 detects the sensing element 620, the drive cylinder 600 can also control the drive rod and piston to stop at a first time threshold, so that the piston continues to compress the material, fully squeezing out the moisture from the material, thereby improving the solid-liquid separation effect. The first time threshold can be 10s, 20s, 30s or other suitable time, and there are no restrictions on this.
[0061] The first sensor 610, located at the end furthest from the compression chamber 300, is positioned such that the sensing element 620 corresponds to the position where the piston moves in the cavity of the compression cylinder away from the transition chamber 400 and the discharge chamber 500. When the first sensor 610 detects the sensing element 620, the drive rod stops retracting to allow the piston to complete the compression of the material. When the piston reaches the position furthest from the transition chamber 400 and the discharge chamber 500 under the drive of the drive rod, it stops to prevent damage to the piston compression chamber 300 from excessive piston movement. Furthermore, when the first sensor 610 detects the sensing element 620, the drive cylinder 600 can also control the drive rod and piston to stop for a second time threshold, allowing sufficient time for the cavity of the compression chamber 300 to be filled with material. The second time threshold can be 10s, 20s, 30s, or other suitable times; there are no restrictions on this.
[0062] See Figure 2 The first sensor 610, located in the middle position, is positioned at approximately 2 / 3 of the distance between the two end sensors 610. When the drive rod extends from the drive cylinder 600 to push the piston and compress the material, in the first 2 / 3 of the stroke, because the material is relatively loose, the drive cylinder 600 only needs to output a small driving force to drive the drive rod and piston to complete the compression. Therefore, before the first sensor 610 in the middle position detects the sensing element 620, the drive cylinder 600 can drive the drive rod and piston to compress the material at a relatively fast speed and with a small driving force, thereby shortening the compression time and reducing energy consumption. In the latter 1 / 3 of the piston stroke, because the material is more compact, the drive cylinder 600 needs a larger driving force to drive the drive rod and piston to complete the compression. Therefore, after the first sensor 610 in the middle position detects the sensing element 620, the drive cylinder 600 can drive the drive rod and piston to compress the material at a slower speed and with a larger driving force, thereby reducing the load on the drive rod and improving the compression effect.
[0063] like Figures 1-4 As shown, one end of the transition chamber 400 is mounted on the compression chamber 300, and the other end is fixedly connected to the discharge chamber 500. The discharge chamber 500 is rectangular in shape, with one end connected to the transition chamber 400 and the other end having a rectangular discharge port 510. Inside the discharge chamber 500, two vertically arranged filter plates 520 are also installed, hinged to the discharge chamber 500 on both sides of the connection point between the discharge chamber 500 and the transition chamber 400. The filter plates 520 extend from one end of the discharge chamber 500 towards the discharge port 510 at the other end, allowing water in the material to pass through the filter plates 520 and separate from the material during compression and passage between them.
[0064] Two filter plates 520 are configured to extend towards the discharge port 510 while one filter plate 520 is tilted towards the other. This allows the material to be conveyed towards the discharge port 510 under the guidance of the filter plates 520, gradually reducing the space between them. The material is then compressed by the two filter plates 520, improving the solid-liquid separation effect. Furthermore, because the space for material passage gradually decreases, a greater thrust is required for the material to pass between the two filter plates 520. This allows the piston in the compression chamber 300, driven by the drive cylinder 600, to compress the material, resulting in a compressive force on the material in the discharge chamber 500 along the extension direction of the drive rod of the drive cylinder 600, further enhancing the solid-liquid separation effect.
[0065] The two filter plates 520 can be fixed by rotating to change the angle between them, thereby adjusting the distance between the ends of the two filter plates 520 facing the discharge port 510. This allows adjustment of the compressive force on the material as it passes between the two filter plates 520, as well as the compressive force required for the material to pass through the space between the two filter plates 520, thus adjusting the solid-liquid separation effect and the moisture content of the material discharged from the discharge port 510. Additionally, the thickness of the material discharged from the discharge port 510 can be adjusted to facilitate the evaporation of moisture from the material.
[0066] like Figure 1 , Figure 2 As shown, two vertically extending baffles 530 are also provided on both sides of the discharge chamber 500, corresponding to the filter plate 520, to prevent water squeezed out from the filter plate 520 from splashing and polluting the environment. The two baffles 530 are detachably connected to the discharge chamber 500, thereby facilitating the maintenance and replacement of the filter plate 520 and other devices in the filter chamber.
[0067] Furthermore, a top plate and a bottom plate are provided above and below the filter plate 520 to restrict the movement direction of the material under the extrusion pressure provided by the drive cylinder 600, thereby preventing material leakage.
[0068] like Figure 1 , Figure 2As shown, a drain outlet 540 is also provided at the bottom of the discharge hopper 500, located near the end where the discharge hopper 500 connects to the transition hopper 400. Due to the pressure between the two filter plates 520, the water in the material flows out through the filter plates 520 and eventually drips to the bottom of the discharge hopper. Since the moisture content of the material is higher closer to the transition hopper 400, more water is squeezed out. Therefore, placing the drain outlet 540 near the end where the discharge hopper 500 connects to the transition hopper 400 facilitates drainage. The bottom of the discharge hopper 500 is sloped, and the drain outlet 540 is located at the bottom of the slope, which guides water from other locations to the drain outlet 540, thereby improving the drainage effect.
[0069] One end of the transition chamber 400 is circular and connects to the compression chamber 300, allowing material in the compression chamber 300 to more easily enter the transition chamber 400. The other end of the transition chamber 400 is a vertically oriented rectangle and connects to the discharge chamber 500. The width of the rectangle is matched to the distance between the hinged ends of the two filter plates 520, allowing material output from the transition chamber 400 to more easily enter between the two transition plates. The two ends of the transition chamber 400 have a smooth transition, allowing the material to gradually change from a cylindrical shape to a cuboid shape within the transition chamber 400, reducing material resistance while transforming the material from round to square.
[0070] like Figures 1-4 As shown, the buffer chamber 200 is positioned above the compression chamber 300, at the top center of the compression chamber 300. The buffer chamber 200 has a square cylindrical structure, with its lower end connected to the compression chamber 300 and its upper end open to form an overflow port 210. The feed chamber 100 is located on the side of the buffer chamber 200, corresponding to the drive cylinder 600, and is connected to the buffer chamber 200 at its center. The material conveyed by the feed chamber 100 enters the compression chamber 300 through the buffer chamber 200, filling the compression chamber 300. The connection between the buffer chamber 200 and the compression chamber 300 is then closed, and the drive cylinder 600 drives the drive rod and piston to compress the material in the compression chamber 300. During the extension and retraction of the drive rod and piston, the connection between the buffer chamber 200 and the compression chamber 300 remains closed to prevent the material from affecting the movement of the drive rod and piston. Meanwhile, the feed hopper 100 continuously feeds material into the buffer hopper 200 so that after the connection between the buffer hopper 200 and the compression hopper 300 is opened, the material can quickly enter the compression hopper 300 to fill it and proceed to the next compression process. This shortens the time required to fill the compression hopper 300 and improves production efficiency.
[0071] like Figure 1 , Figure 2As shown, a second sensor 220 is also installed on the buffer chamber 200 near the overflow port 210. The second sensor 220 can detect the height of the material in the buffer chamber 200. When the material in the buffer chamber 200 is too high and approaches the overflow port 210, the feed hopper 100 can be controlled to slow down the speed of feeding material into the buffer chamber 200, or the feed hopper 100 can be controlled to stop feeding material into the buffer chamber 200. This prevents the material in the buffer chamber 200 from becoming too high and overflowing from the overflow port 210, thus avoiding environmental pollution.
[0072] like Figures 1-4 As shown, the upper part of the feeding hopper 100 is flared, with a feed inlet 110 formed at the top to facilitate the conveying of materials into the feeding hopper 100. An auger 120 is installed at the lower part of the feeding hopper 100, extending from the feeding hopper 100 into the buffer hopper 200 to convey materials entering the feeding hopper 100 through the feed inlet 110 to the buffer hopper 200. A vibration motor 130 is also installed on the side wall of the feeding hopper 100 near the feed inlet 110. The vibration motor 130 vibrates the feeding hopper 100, causing materials adhering to the inner side wall of the feeding hopper 100 to flow downwards, driving the materials to fall quickly into the area where the auger operates, thus propelling the materials into the buffer hopper 200.
[0073] like Figure 1 , Figure 2 As shown, the feed hopper 100 and the drive cylinder 600 are located on the same side, which reduces the space occupied by the material handling machine 10 and facilitates equipment installation. A support 140 is also provided at the bottom of the feed hopper 100. The support 140 is generally a right-angled triangle. One right-angled side of the support 140 is fixedly connected to the feed hopper 100 along the extension direction of the auger 120 at the middle position of the feed hopper 100, and the other right-angled side extends downwards and is fixedly connected to the drive cylinder 600 by bolts. Thus, the support 140 can support the feed hopper 100, thereby improving the stability of the feed hopper 100.
