[0014] Compared with the prior art, the beneficial effects of the present invention are: the environmentally friendly material feeding device provides stable feeding, facilitates the adjustment of the depth of the discharge end in the carriage by the operator, effectively reduces the workload of the operator, and allows adjustment of the discharge angle of the bio-based environmentally friendly material, so that the granular bio-based environmentally friendly material is evenly transported to each horizontal surface of the carriage, avoiding the accumulation of granular bio-based environmentally friendly material in one place and improving the feeding uniformity of the device.

[0015] (1) Through the structure of telescopic sleeve and feeding main pipe, bio-based environmental protection materials are put into feeding main pipe through the feed inlet. The material conveying unit pushes the bio-based environmental protection materials. As the materials in the carriage gradually accumulate, the staff controls the overall length of feeding main pipe, feeding auxiliary pipe and telescopic sleeve. The insertion depth of telescopic sleeve and discharge angle adjustment component is inversely proportional to the amount of material accumulation. The adjustable length conveying pipe formed by feeding main pipe, feeding auxiliary pipe and telescopic sleeve makes it easy for the staff to adjust the depth of the discharge end in the carriage. During this process, the staff does not need to manually adjust the relative position between the device and the carriage, saving the work of adjusting the discharge position of the device, which can effectively reduce the workload of the staff.

[0016] (2) By setting up a structure with auger rollers and ceramic inner liner working together, during the feeding process, the staff turns on the main motor through the PLC control panel. The main motor drives the drive shaft and the drive sprocket to rotate in sequence. The drive sprocket drives the driven sprocket and auger roller to rotate through the chain. Then the auger roller pushes and mixes the bio-based environmentally friendly material in the ceramic inner liner. The feeding process is stable and reliable. The discharge speed is determined by the rotation of the main motor. Since the outer diameter of the auger roller is smaller than the inner diameter of the telescopic sleeve, the auger roller will not affect the telescopic sleeve when the telescopic sleeve moves in the ceramic inner liner, ensuring stable material conveying.

[0017] (3) By setting up a structure with right-angle bends and main hollow discs, the discharge angle of bio-based environmental protection materials is adjusted by rotating the discharge angle adjustment component, so that the granular bio-based environmental protection materials are evenly transported to each horizontal surface of the carriage, avoiding the accumulation of granular bio-based environmental protection materials in one place, improving the uniformity of feeding of the device. The constriction at one end of the telescopic sleeve and the constriction at the end of the discharge pipe match each other, thereby reducing the gaps in the pipe and the pipe connection, so that the granular bio-based environmental protection materials can enter the discharge pipe and right-angle bend without obstruction until they are discharged.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] Example 1, by Figures 1 to 8 The present invention includes two sets of gantry supports 1, each set of gantry supports 1 has a bracket 4 fixed at its top, and a feeding pipe 5 is installed between the two sets of brackets 4. A feeding port 501 is provided on one side of the top of the feeding pipe 5. The operator puts the bio-based environmentally friendly material to be fed into the feeding pipe 5 through the feeding port 501.

[0029] The feeding main pipe 5 is equipped with a material conveying unit that pushes bio-based environmentally friendly granular materials. A drive protective shell 3 is installed on the outer wall of one side of the gantry support 1. The drive protective shell 3 is equipped with a single chain drive structure that drives the material conveying unit. A main motor 2 is installed on one side of the gantry support 1. The output end of the main motor 2 is connected to the single chain drive structure.

[0030] A flange 502 is fixed to the end of the main feeding pipe 5 away from the drive protective shell 3. A feeding auxiliary pipe 6 is installed at the end of the flange 502. A bracket 7 is fixed to the end of the feeding auxiliary pipe 6 away from the flange 502. A telescopic sleeve 10 is slidably installed inside the feeding auxiliary pipe 6. One end of the telescopic sleeve 10 extends into the interior of the main feeding pipe 5. The outer diameter of the telescopic sleeve 10 is less than or equal to the inner diameter of the main feeding pipe 5. A driven rack 1001 is installed at the top of the telescopic sleeve 10. The driven rack 1001 is arranged along the length of the telescopic sleeve 10.

[0031] The transfer locking assembly includes a lower straight frame 8 fixed to the top of the bracket 7, and an upper straight frame 801 fixed to the top of the lower straight frame 8. A first motor 9 is installed on the top of the upper straight frame 801. A linear locking structure is installed at the output end of the first motor 9. A rack and pinion moving structure that cooperates with the linear locking structure is installed inside the lower straight frame 8. The output end of the first motor 9 is electrically connected to the input end of the PLC control panel 101.

[0032] The rack and pinion moving structure includes a short shaft 12 rotatably installed inside the lower straight frame 8. A drive gear 1201 is fixed on one side of the surface of the short shaft 12. The drive gear 1201 and the driven rack 1001 mesh with each other. The operator needs to control the depth of the telescopic sleeve 10 in the carriage. That is, the insertion depth of the telescopic sleeve 10 and the discharge angle adjustment component 11 is inversely proportional to the amount of material accumulation.

[0033] The linear locking structure includes a rotating shaft 13 installed at the output end of the first motor 9. A long worm shaft 14 is installed at the bottom end of the rotating shaft 13. The linear locking structure also includes a worm wheel 15 installed on one side of the surface of the short shaft 12. The long worm shaft 14 and the worm wheel 15 mesh with each other. Through the linear locking structure formed by the worm wheel 15 and the long worm shaft 14, the material is prevented from impacting the telescopic sleeve 10 and moving on its own when it enters the telescopic sleeve 10, that is, the relative length of the feeding main pipe 5 and the telescopic sleeve 10 is maintained.

[0034] The top of the support frame 7 is equipped with a transfer locking assembly that drives the telescopic sleeve 10 to move horizontally. A PLC control panel 101 is installed on the outer wall of one side of the gantry support 1. The output terminal of the PLC control panel 101 is electrically connected to the input terminal of the main motor 2. The operator starts the first motor 9 through the PLC control panel 101, so that the first motor 9 works through the linear locking structure and the rack and pinion moving structure. During this process, the first motor 9 drives the rotating shaft 13 and the long shaft of the worm gear 14 to rotate. The long shaft of the worm gear 14 drives the meshing worm wheel 15 to rotate. Then the worm wheel 15 drives the short shaft 12 and the drive gear 1201 to rotate together. Since the drive gear 1201 and the driven rack 1001 mesh with each other, when the drive gear 1201 rotates clockwise, the drive gear 1201 forces the driven rack 1001 and the telescopic sleeve 10 to move to the left, so that the telescopic sleeve 10 is put into the feeding main pipe 5.

[0035] The adjustable-length conveying pipeline formed by the main feeding pipe 5, the auxiliary feeding pipe 6, and the telescopic sleeve 10 facilitates the adjustment of the depth of the discharge end in the carriage by the staff. During this process, the staff does not need to manually adjust the relative position between the device and the carriage, saving the work of adjusting the discharge position of the device and effectively reducing the workload of the staff.

[0036] Example 2, based on Example 1, is...Figure 1 , Figure 2 and Figure 5 The material conveying unit includes a ceramic inner liner 503 installed inside the main feeding pipe 5. The inner diameter of the ceramic inner liner 503 is greater than or equal to the outer diameter of the telescopic sleeve 10. An auger roller 504 is rotatably installed inside the ceramic inner liner 503. The outer diameter of the auger roller 504 is less than or equal to the inner diameter of the telescopic sleeve 10. One end of the auger roller 504 extends into the interior of the drive protective shell 3 and is interconnected with the single chain drive structure.

[0037] The single-chain drive structure includes a drive shaft 301 installed at the output end of the main motor 2. One end of the drive shaft 301 extends into the interior of the drive protective housing 3 and is rotatably connected to the inner wall of the drive protective housing 3. A drive sprocket 302 is fixed on one side of the surface of the drive shaft 301. A driven sprocket 505 is installed at one end of the auger roller 504. A chain 303 is fitted between the driven sprocket 505 and the drive sprocket 302.

[0038] The operator starts the main motor 2 through the PLC control panel 101, which drives the material conveying unit in the main feeding pipe 5 through the single chain transmission structure. The bio-based environmentally friendly material is pushed into the secondary feeding pipe 6. During the feeding process, the operator starts the main motor 2 through the PLC control panel 101. The main motor 2 drives the transmission shaft 301 and the drive sprocket 302 to rotate in sequence. The drive sprocket 302 then drives the driven sprocket 505 and the auger roller 504 to rotate through the chain 303.

[0039] The auger roller 504 pushes and mixes the bio-based environmentally friendly materials in the ceramic inner liner 503. The feeding process is stable and reliable, and the discharge speed is determined by the rotation of the main motor 2. Since the outer diameter of the auger roller 504 is smaller than the inner diameter of the telescopic sleeve 10, the auger roller 504 will not affect the telescopic sleeve 10 when the telescopic sleeve 10 moves in the ceramic inner liner 503, thus ensuring stable material conveying.

[0040] Example 3, based on Example 1, is... Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, the end of the telescopic sleeve 10 away from the bracket 7 is equipped with a discharge angle adjustment component 11 to control the discharge angle of the material. In order to better adjust the discharge angle of the telescopic sleeve 10, the staff can adjust its discharge angle through the discharge angle adjustment component 11 so that the material is evenly piled in the carriage.

[0041] The discharge angle adjustment assembly 11 includes a main hollow disk 1101 installed at the discharge port of the telescopic sleeve 10, a secondary hollow disk 1102 installed on the outer wall of one side of the main hollow disk 1101, and the internal rotation of the main hollow disk 1101 and the secondary hollow disk 1102 is achieved by a discharge pipe 1103 installed through a hollow rotating unit. One end of the discharge pipe 1103 extends into the interior of the telescopic sleeve 10, and a right-angle bend 1105 is installed at the end of the discharge pipe 1103 away from the secondary hollow disk 1102. A pulley drive structure that drives the hollow rotating unit is installed at the bottom end of the secondary hollow disk 1102. A constriction section 1104 is provided at the end of the discharge pipe 1103 away from the right-angle bend 1105. The operator starts the second motor 1107 through the PLC control panel 101. The second motor 1107 drives the hollow rotating unit through the pulley drive structure.

[0042] One end of the telescopic sleeve 10 is provided with a constriction 1002. The constriction 1002 and the narrowed part 1104 fit together. The constriction 1002 at one end of the telescopic sleeve 10 and the narrowed part 1104 at the end of the discharge pipe 1103 fit together, thereby reducing the gaps in the pipe and the pipe connection, allowing granular bio-based environmentally friendly materials to enter the discharge pipe 1103 and the right-angle bend 1105 without obstruction, until they are discharged.

[0043] The hollow rotary unit includes an external gear ring 1111 mounted on one side of the surface of the discharge pipe 1103. A concentric shaft 1112 is rotatably mounted on the outer wall of the main hollow disk 1101 on one side of the external gear ring 1111. One end of the concentric shaft 1112 extends into the interior of the main hollow disk 1101 and is connected to the pulley drive structure. A direct drive gear 1113 is fixed to the other end of the concentric shaft 1112. The direct drive gear 1113 and the external gear ring 1111 mesh with each other. The pulley drive structure includes a second driven pulley fixed to one end of the concentric shaft 1112. The pulley drive structure also includes a vertical plate 1106 fixed to the bottom end of the secondary hollow disk 1102. A [missing information - likely a device or structure] is mounted on the outer wall of one side of the vertical plate 1106. The second motor 1107 has a central shaft 1108 installed at its output end. The top of the central shaft 1108 is equipped with a first drive pulley 1109. The first drive pulley 1109 and the second driven pulley are fitted together with a track 1110. The second motor 1107 first drives the central shaft 1108 and the first drive pulley 1109 to rotate. Then the track 1110 drives the second driven pulley at the other end of the concentric shaft 1112 to rotate. That is, the concentric shaft 1112 and the direct drive gear 1113 are driven to rotate. Since the direct drive gear 1113 and the external gear ring 1111 mesh with each other, the direct drive gear 1113 drives the external gear ring 1111 and the discharge pipe 1103 to rotate.

[0044] The material pushed in the telescopic sleeve 10 enters the discharge pipe 1103 and the right-angle bend 1105 rotates. When the discharge pipe 1103 rotates, the material outlet direction of the right-angle bend 1105 is adjusted. The discharge angle of the bio-based environmentally friendly material is adjusted by the rotation angle of the right-angle bend 1105, so that the granular bio-based environmentally friendly material is evenly transported to each horizontal surface of the carriage, avoiding the accumulation of granular bio-based environmentally friendly material in one place and improving the feeding uniformity of the device.

[0045] In this embodiment, the operator first feeds the bio-based environmentally friendly material into the main feeding pipe 5 through the inlet 501. At this time, the telescopic sleeve 10 and the discharge angle adjustment component 11 are at the deepest part of the carriage. Then, the operator starts the main motor 2 through the PLC control panel 101, which drives the material conveying unit in the main feeding pipe 5 through a single-chain transmission structure. The bio-based environmentally friendly material is then pushed into the secondary feeding pipe 6. As the material gradually accumulates in the carriage, the operator needs to control the depth of the telescopic sleeve 10 in the carriage. That is, the insertion depth of the telescopic sleeve 10 and the discharge angle adjustment component 11 is inversely proportional to the amount of material accumulated. At this time, the operator starts the first motor 9 through the PLC control panel 101, which operates through a linear locking structure and a rack and pinion moving structure. During this process, the first motor 9 drives the rotating shaft 13 and the long worm shaft 14 to rotate, which in turn drives the meshing worm wheel 15 to rotate. The worm gear 15 drives the short shaft 12 and the drive gear 1201 to rotate together. Since the drive gear 1201 and the driven rack 1001 mesh with each other, when the drive gear 1201 rotates clockwise, it forces the driven rack 1001 and the telescopic sleeve 10 to move to the left, thereby causing the telescopic sleeve 10 to be drawn into the main feeding pipe 5. The inner diameter of the ceramic inner liner 503 is equal to the outer diameter of the telescopic sleeve 10. Through the linear locking structure formed by the worm gear 15 and the long shaft 14 of the worm, the material is prevented from impacting the telescopic sleeve 10 and moving on its own when it enters the telescopic sleeve 10, thus maintaining the relative length of the main feeding pipe 5 and the telescopic sleeve 10. The adjustable length conveying pipe formed by the main feeding pipe 5, the secondary feeding pipe 6, and the telescopic sleeve 10 makes it easy for the staff to adjust the depth of the discharge end in the carriage. During this process, the staff does not need to manually adjust the relative position between the device and the carriage, saving the work of adjusting the discharge position of the device and effectively reducing the workload of the staff.
