Description

Technical Field

[0001] This invention relates to the field of hydroseeding machine technology, specifically to a self-weighing mixing mechanism and a weighing mixing method for a hydroseeding machine. Background Technology

[0002] In agricultural planting, ecological restoration, and mine revegetation, hydroseeding machines are key equipment for material mixing and spraying operations. The performance of their mixing mechanism directly affects operational efficiency, material utilization, and spraying quality. In existing hydroseeding machines, materials tend to adhere to the inner wall of the mixing tank due to stickiness or centrifugal force during the mixing process, forming a continuously accumulating residue layer. These residues cannot participate in subsequent mixing processes, directly causing material waste and reducing mixing efficiency. Moreover, the accumulation of residues on the tank wall can disrupt the uniformity of mixing. After long-term adhesion, the residues may solidify or clump, resulting in uneven mixing with newly added materials and affecting the quality of the final sprayed material.

[0003] Patent CN113994854B discloses a special hydroseeding machine for SPF soilless wood fiber hydroseeding process. The above patent realizes the real-time change of the flow rate and head of the hydroseeding machine and the free switching of the amount of wood fiber mixed liquid flow.

[0004] The aforementioned patent allows for real-time adjustment of the flow rate and head of the hydroseeder according to different working environment requirements, and the amount of wood fiber mixed liquid can be freely switched. However, there is still room for optimization in the scraping and reuse of residual mixed material on the tank wall.

[0005] Therefore, this application proposes a self-weighing mixing mechanism and weighing mixing method for a hydroseeding machine that can efficiently scrape off residual mixture from the tank wall for reuse. Summary of the Invention

[0010] Preferably, a first drive motor is provided in the motor slot, and a threaded rod is provided on the outer side of the first drive motor. The threaded rod meshes with the threaded groove on the inner side of the threaded cylinder through the thread on the outer side of the outer wall. A buffer spring is provided at the bottom of the outer wall of the threaded cylinder. One end of the buffer spring is connected to the threaded cylinder, and the other end of the buffer spring is connected to the bottom of the inner wall of the adjusting slot.

[0011] Preferably, the adjustment groove is located on the side of the outer wall of the rear robotic arm, and a telescopic outer cylinder is located at the bottom of the inner wall of the adjustment groove. A buffer spring is surrounded on the outside of the telescopic outer cylinder. The telescopic outer cylinder is hollow inside, and two symmetrically distributed slots are located on the inner wall of the telescopic outer cylinder. The slots and the locking ridges are interlocked. The locking ridges are located on the side of the outer wall of the telescopic inner cylinder. The telescopic inner cylinder is located in the hollow part inside the telescopic outer cylinder, and the top of the outer wall of the telescopic inner cylinder is connected to the bottom of the outer wall of the threaded cylinder.

[0012] Preferably, the inner side of the upper interface and the outer side of the rotating rod are fitted together.

The outer wall of the second drive motor is provided with a data line. The data line is connected to the mechanical rod through the fixed rod and then connected to the operation screen through the mechanical rod.

[0013] Preferably, the outer wall of the rotating rod is provided with a protrusion, the outer wall of the protrusion and the inner wall of the groove at the bottom of the connecting box are fitted together, the rotating rod passes through the lower interface of the connecting box and enters the interior of the mixing tank, the inner wall of the mixing tank is fitted together with the outer wall of the two scrapers, and the outer wall of the rotating rod is provided with a spiral blade.

[0014] Preferably, a vibration motor is provided at the top of the outer wall of the rotating block, and a connecting wire is provided on the side of the outer wall of the vibration motor. The connecting wire enters the hollow area inside the rotating rod along the front and rear robotic arms.

The data line and the connecting wire are connected to the bottom of the outer wall of the wiring rotator inside the rotating rod. A bus is provided at the top of the outer wall of the wiring rotator. The bus enters the operation screen along the fixed rod and through the mechanical rod.

[0015] Preferably, the mixing method includes the following steps:

[0016] S1. Material input and scraper adjustment: Input the material to be mixed into the mixing tank. The operator starts the first drive motor through the control panel. The first drive motor drives the threaded rod to rotate. The rotation of the threaded rod drives the threaded cylinder to move axially. The threaded cylinder pushes the buffer spring to compress. The buffer spring pushes the robotic arm to rotate outward, thereby causing the front robotic arm to drive the rotating block to move outward until the scraper is in contact with the inner wall of the mixing tank.

[0017] S2. Stirring and scraping operation: The operator starts the second drive motor through the control panel. The second drive motor drives the rotating rod and the spiral blade to rotate and stir the material. At the same time, the connecting box rotates with the rotating rod, which drives the scraper to move circumferentially along the inner wall of the mixing tank. The arc-shaped scraper scrapes off the residual material on the tank wall and returns it to the tank through the figure-7 scraper.

[0018] Preferably, the mixing method further includes the following steps:

[0019] S3. Residue Removal: If the operator observes that there is still mixed material residue on the tank wall, the first drive motor is restarted through the operation panel to increase the outward movement of the threaded cylinder, thereby increasing the compression force of the buffer spring and pushing the scraper to further press against the tank wall. The residual mixed material is scraped off by rotation, and the buffer spring also buffers the reaction force of the hard mixed material.

[0020] S4. Residual Vibration Removal and Buffer Protection: After the scraper finishes scraping the wall, the operator starts the first drive motor to drive the scraper to retract and detach from the tank wall. Then, the vibration motor is started. The vibration motor drives the scraper to vibrate and remove residual materials from the surface. During the vibration process, the buffer spring in the regulating tank absorbs vibration energy through its reciprocating motion, reducing equipment damage.

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

[0022] 1. This invention, by installing a connecting box, a rear robotic arm, a front robotic arm rotating block, a scraper, and an arc-shaped scraper, achieves simultaneous scraping and reuse of material mixing and tank wall residue. The connecting box rotates with the rotating rod, driving the scraper to move circumferentially along the tank wall. The arc-shaped scraper scrapes away the residual mixture and returns it to the tank through the figure-7 scraper, improving the utilization rate of materials, ensuring the uniformity of mixing, reducing material waste, and solving the problems of material waste, insufficient mixing, and difficult subsequent cleaning caused by the accumulation of residue on the tank wall in the prior art.

[0023] 2. This invention, by installing a first drive motor, a threaded rod, a threaded cylinder, a buffer spring, and a rear robotic arm, achieves precise adjustment of the scraper's fit against the tank wall. The first drive motor drives the threaded rod to rotate, which in turn drives the buffer spring through threaded transmission, thereby driving the robotic arm to adjust the scraper position. This can adapt to the scraping requirements of materials with different viscosities, avoid excessive scraper wear or incomplete residue removal, and solve the problem of poor scraping effect or rapid equipment wear caused by the fixed scraper pressure in the prior art, which cannot match the characteristics of different materials.

[0024] 3. This invention achieves directional limiting and vibration buffering of mechanical transmission by installing a telescopic outer cylinder, a telescopic inner cylinder, and a buffer spring. The telescopic outer cylinder and the telescopic inner cylinder restrict the rotation of the threaded cylinder through the cooperation of the locking edge and the locking groove to achieve directional movement, ensuring the directional movement of the scraper. The buffer spring absorbs the impact force generated by transmission and vibration, improves the stability of the mixing mechanism, reduces the collision damage to the rigidity of the components, and solves the problem in the prior art that mechanical transmission is prone to wear of components or decrease in operating accuracy due to misalignment or vibration.

[0025] 4. This invention, by installing a vibrating motor, a rotating block, a scraper, and a connecting line, achieves the removal of residual mixed material on the scraper surface. The vibrating motor drives the scraper to vibrate through the rotating block, causing the attached material to fall off, keeping the scraper clean, avoiding secondary pollution from residual material and affecting the scraping efficiency. It solves the problem in the prior art that the scraper itself is prone to material adhesion, resulting in a decrease in scraping effect or cross-contamination of materials.

[0038] Please see Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 An embodiment of the present invention provides a self-weighing mixing mechanism for a hydroseeding machine. A scraper 17 is provided on the front side of the outer wall of the rotating block 15. The scraper 17 is shaped like the number 7. An arc-shaped scraper 18 is provided on the inner side of the scraper 17. A first drive motor 23 is provided in the motor slot 7. A threaded rod 24 meshes with the threaded groove on the inner side of the threaded cylinder 25 through the thread on the outer side of the outer wall. A buffer spring 26 is provided at the bottom of the outer wall of the threaded cylinder 25. An adjustment slot 11 is provided on the outer side of the rear mechanical arm 8. A telescopic outer cylinder 29 is provided at the bottom of the inner wall of the adjustment slot 11. A buffer spring 26 surrounds the outer side of the telescopic outer cylinder 29. A slot 30 and a ridge 28 are fitted together. The ridge 28 is provided on the outer side of the telescopic inner cylinder 27. A first connecting shaft 34 passes through the first screw hole 4, the second screw hole 6 and the first connecting hole 9 to fix the rear mechanical arm 8 on the connecting box 1. A third connecting shaft 36 passes through the fourth connecting hole 14 and the fifth connecting hole 16 to fix the rotating block 15 on the front mechanical arm 12.

[0039] Furthermore, before starting the mixing mechanism, the operator first puts the material into the mixing tank 33, then adjusts the scraper 17 until it is in contact with the inner wall of the mixing tank 33. The operator clicks the operation screen 40 to start the first drive motor 23. The first drive motors 23 on both sides of the connecting box 1 start simultaneously, driving the threaded rod 24 to rotate. The threaded rod 24 and the threaded cylinder 25 are interlocked. The rotation of the threaded rod 24 drives the threaded cylinder 25 to move axially outward. The bottom end of the outer wall of the threaded cylinder 25 is connected to the telescopic inner cylinder 27. The telescopic inner cylinder 27 is prevented from rotating by itself through the engagement of the locking rib 28 and the locking groove 30, thus converting the rotational movement of the threaded cylinder 25 into... Axial movement causes the threaded cylinder 25 to move outward, driving the telescopic inner cylinder 27 to move along the telescopic outer cylinder 29. This outward movement is a movement away from the first drive motor 23. Simultaneously, the movement of the threaded cylinder 25 causes the buffer spring 26 to be gradually compressed. The buffer spring 26 then converts the compression force into elastic force, which is transmitted to the rear robotic arm 8. After receiving the elastic force, the rear robotic arm 8 moves outward along the first connecting shaft 34. The outward movement of the rear robotic arm 8 drives the front robotic arm 12 to move outward. The outward movement of the front robotic arm 12 drives the rotating block 15 to move outward. The outward movement of the rotating block 15 drives the scraper 17 to move towards the inner wall of the mixing tank 33 until the outer side of the scraper 17 is in contact with the mixing tank 33 and stops.

[0040] Please see Figure 2 , Figure 3 , Figure 7 and Figure 8 An embodiment of the present invention provides a self-weighing mixing mechanism for a hydroseeding machine. A rotating rod 21 passes through an upper interface 2 and is connected to a second drive motor 31 located on the top of the outer wall of a fixed rod 32. A data cable is provided on the outer wall of the second drive motor 31. The data cable is connected to a mechanical rod 39 through the fixed rod 32 and to an operation screen 40 through the mechanical rod 39. A rear mechanical arm 8 is provided between a first flange 3 and a second flange 5. The rear mechanical arm 8 is connected to the first flange 3 and the second flange 5 through a first connecting hole 9. The rear mechanical arm 8 is connected to a front mechanical arm 12 through a second connecting hole 10. The front mechanical arm 12 is connected to a rotating block 15 through a fourth connecting hole 14. A scraper 17 is provided on the front side of the outer wall of the rotating block 15, and an arc-shaped scraper 18 is provided on the inner side of the scraper 17.

[0041] Furthermore, when the two scrapers 17 are completely in contact with the inner wall of the mixing tank 33, the operator controls the second drive motor 31 to start via the control panel 40. The second drive motor 31 drives the rotating rod 21 to rotate. The connecting box 1 is fixed to the rotating rod 21 by the engagement of the groove 38 with the protrusion of the rotating rod 21. The rotation of the rotating rod 21 drives the rotation of the connecting box 1, which in turn drives the spiral blades 22 on the outer wall to rotate. The rotation of the spiral blades 22 stirs the material in the mixing tank 33. At the same time, the rotation of the connecting box 1 drives the rear motors on both sides of the outer wall to rotate. The robotic arm 8 rotates above the mixing tank 33. The rear robotic arm 8 is connected to the front robotic arm 12, which is connected to the rotating block 15. The rotating block 15 is connected to the scraper 17. The scraper 17 rotates under the drive of the connecting box 1. The scraper 17 is in contact with the inner wall of the mixing tank 33, thereby scraping the mixture off the side wall of the mixing tank 33. The inner edge of the scraper 17 is provided with an arc-shaped scraper 18. The arc-shaped scraper 18 scrapes the mixture on the side wall of the mixing tank 33 under the action of rotation, and flows back into the mixing tank 33 along the 7-shaped scraper 17, so as to realize the full utilization of the mixture.

[0042] Please see Figure 2 , Figure 4 , Figure 5 and Figure 6 An embodiment of the present invention provides a self-weighing mixing mechanism for a hydroseeding machine. The data cable at the bottom of the outer wall of the first drive motor 23 passes through the connecting box 1 and enters the interior of the rotating rod 21. The data cable is connected to the bottom of the outer wall of the wiring rotator inside the rotating rod 21. A bus is provided at the top of the outer wall of the wiring rotator. The bus passes along the fixed rod 32 and enters the operation screen 40 through the mechanical rod 39. The rotating rod 21 passes through the lower interface 37 of the connecting box 1 and enters the interior of the mixing tank 33. A telescopic outer cylinder 29 is provided at the bottom of the inner wall of the adjusting groove 11. A buffer spring 26 surrounds the outside of the telescopic outer cylinder 29. A slot 30 is provided on the side of the inner wall of the telescopic outer cylinder 29. A locking ridge 28 is provided on the side of the outer wall of the telescopic inner cylinder 27. The top of the outer wall of the telescopic inner cylinder 27 is connected to the bottom of the outer wall of the threaded cylinder 25. The second connecting shaft 35 passes through the third connecting hole 13 and the second connecting hole 10 to fix the front mechanical arm 12 on the rear mechanical arm 8.

[0043] Furthermore, when the operator observes that a small amount of mixed material remains on the inner wall of the mixing tank 33, the operator starts the first drive motor 23 via the control panel 40. The first drive motor 23 drives the threaded rod 24 to rotate, which in turn drives the threaded cylinder 25 to move axially outward. The axial outward movement of the threaded cylinder 25 pushes the telescopic inner cylinder 27 outward, allowing it to enter the telescopic outer cylinder 29 along the slot 30. The axial outward movement of the threaded cylinder 25 compresses the buffer spring 26. The buffer spring 26 is located on the outside of the telescopic outer cylinder 29, ensuring that the buffer spring 26 can only move along the direction of the telescopic outer cylinder 29 during compression and extension, preventing bending and deformation of the buffer spring 26 during compression and extension. The buffer spring 26 converts the compressive force into elastic force, which is then transmitted to the rear robotic arm 8. Under the push of the elastic force, the rear robotic arm 8 rotates outward through the first connecting shaft 34. The outward rotation of the rear robotic arm 8 drives the front robotic arm 12 to rotate outward through the second connecting shaft 35. The outward rotation of the front robotic arm 12 drives the rotating block 15 to rotate outward through the third connecting shaft 36. The outward rotation of the rotating block 15 drives the scraper 17 to move outward, increasing the pressing force of the scraper 17 on the inner wall of the mixing tank 33, thereby scraping the residual mixture into the mixing tank 33. At the same time, when the scraper 17 scrapes the hard mixture on the inner wall of the mixing tank 33, the scraper 17 scrapes off a part of the hard mixture. At the same time, the scraper 17 will be compressed inward under the reaction thrust of the hard mixture. The compression force is buffered by the buffer spring 26 in the adjustment groove 11 of the rear robotic arm 8 to avoid damage to the rigidity of the scraper 17. The scraper 17 on the other side scrapes the remaining hard mixture into the mixing tank 33.

[0044] Please see Figure 1 , Figure 2 and Figure 7 An embodiment of the present invention provides a self-weighing mixing mechanism for a hydroseeding machine. A vibration motor 19 is provided at the top of the outer wall of the rotating block 15. A connecting line 20 is provided on the side of the outer wall of the vibration motor 19. The connecting line 20 enters the hollow area inside the rotating rod 21 along the front mechanical arm 12 and the rear mechanical arm 8. The data line at the bottom of the outer wall of the first drive motor 23 passes through the connecting box 1 and enters the interior of the rotating rod 21. The data line and the connecting line 20 are connected to the bottom of the outer wall of the wiring rotator inside the rotating rod 21. A bus is provided at the top of the outer wall of the wiring rotator. The bus enters the operation screen 40 along the fixed rod 32 through the mechanical rod 39.

[0045] Furthermore, after the scraper 17 has scraped the mixed material from the inner wall of the mixing tank 33, the operator controls the first drive motor 23 to start. The first drive motor 23 drives the scrapers 17 on both sides to retract inward, detaching from the mixing tank 33, and then removes the remaining mixed material on the scraper 17. At this time, the operator starts the vibration motor 19 through the operation panel 40. The operation panel 40 transmits the instructions to the connection line 20 through the bus and the wiring rotator. The wiring rotator is a device used to solve the electrical connection between the rotating rod 21 and the fixed rod 32. It can connect the bus in the fixed rod 32 to the connection line 20 of the rotating rod 21, eliminating the problem of cable entanglement during rotation. At this time, the vibration motor 19 at the top of the outer wall of the rotating blocks 15 on both sides starts. The vibration motor 19 vibrates continuously, driving the scraper 17 to vibrate. Under the vibration, the scraper 17 shakes the remaining mixed material into the mixing tank 33, realizing the full utilization of the mixed material.

[0046] Please see Figure 2 , Figure 4 , Figure 5 and Figure 6 An embodiment of the present invention provides a self-weighing mixing mechanism for a hydroseeding machine. The telescopic outer cylinder 29 is surrounded by a buffer spring 26. The inner wall of the telescopic outer cylinder 29 is provided with two symmetrically distributed slots 30. The slots 30 and the locking ridges 28 are interlocked. The locking ridges 28 are provided on the side of the outer wall of the telescopic inner cylinder 27. The top of the outer wall of the telescopic inner cylinder 27 is connected to the bottom of the outer wall of the threaded cylinder 25. One end of the buffer spring 26 is connected to the threaded cylinder 25, and the other end of the buffer spring 26 is connected to the bottom of the inner wall of the adjusting groove 11.

[0047] Furthermore, when the scrapers 17 on both sides vibrate to remove the mixed material, the vibration of the vibrating motor 19 drives the rotating block 15 to vibrate. The vibration of the rotating block 15 is transmitted to the front robotic arm 12, which then transmits the vibration to the rear robotic arm 8. The vibration of the rear robotic arm 8 drives the vibration of the buffer spring 26 in the adjusting groove 11. The buffer spring 26 absorbs and dissipates the vibration energy through the reciprocating motion of compression and stretching between the springs. When vibration energy is introduced, the buffer spring 26 is compressed, converting the vibration kinetic energy into elastic potential energy. When the vibration energy weakens, the spring returns to its original state, releasing the elastic potential energy and converting it into heat energy through internal friction. This reduces the damage to the equipment caused by the vibration energy of the vibrating motor 19 and extends the overall service life of the equipment.

[0048] Working principle: First, the position of scraper 17 is adjusted by the first drive motor 23. After the operator starts the first drive motor 23, it drives the threaded rod 24 to rotate. The threaded rod 24 meshes with the threaded cylinder 25, causing the threaded cylinder 25 to move axially. The threaded cylinder 25 pushes the buffer spring 26 to compress. The buffer spring 26 transmits the force to the rear robotic arm 8, which drives the rotating block 15 to rotate outward through the front robotic arm 12, so that the scraper 17 fits against the inner wall of the mixing tank 33, preparing for the scraping of the mixed material.

[0049] Then the operator starts the second drive motor 31, which drives the rotating rod 21 to rotate. The spiral blades 22 on the outer wall of the rotating rod 21 stir the material. At the same time, the connecting box 1 rotates synchronously with the rotating rod 21, driving the mechanical arms on both sides and the scraper 17 to move in a circular motion. The scraper 17 adheres to the tank wall, and the arc-shaped scraper 18 scrapes up the residual mixture on the side wall and flows back into the mixing tank 33 along the 7-shaped scraper 17, improving the material utilization rate. When there is hard mixture residue, the first drive motor 23 is started again to increase the pressure of the scraper 17. The threaded cylinder 25 moves further outward, and the compression force of the buffer spring 26 is increased, causing the scraper 17 to press tightly against the tank wall and scrape off the hard residue. At the same time, the buffer spring 26 buffers the reaction force of the hard mixture to avoid damage to the rigidity of the scraper 17.

[0050] Finally, scraper 17 retracts and detaches from the tank wall. The operator starts the vibration motor 19. The vibration is transmitted to scraper 17 through rotating block 15, causing the residual material on scraper 17 to fall into mixing tank 33. Buffer spring 26 absorbs vibration energy through reciprocating motion and converts it into heat energy to dissipate, reducing damage to the equipment and extending its service life.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

A weighing and mixing method for a self-weighing mixing mechanism of a hydroseeding machine, applicable to the self-weighing mixing mechanism of a hydroseeding machine as described in any one of claims 1-8, characterized in that: The mixing method includes the following steps: S1. Material input and scraper adjustment: Input the material to be mixed into the mixing tank (33). The operator starts the first drive motor (23) through the operation screen (40). The first drive motor (23) drives the threaded rod (24) to rotate. The rotation of the threaded rod (24) drives the threaded cylinder (25) to move axially. The threaded cylinder (25) pushes the buffer spring (26) to compress. The buffer spring (26) pushes the rear mechanical arm (8) to rotate outward, so that the front mechanical arm (12) drives the rotating block (15) to move outward until the scraper (17) is in contact with the inner wall of the mixing tank (33). S2. Stirring and scraping operation: The operator starts the second drive motor (31) through the operation screen (40).

The weighing and mixing method of the self-weighing mixing mechanism of a hydroseeding machine according to claim 9, characterized in that: The mixing method further includes the following steps: S3. Residual Removal: If the operator observes that there is still mixed material residue on the tank wall, the first drive motor (23) is restarted again through the operation panel (40) to increase the outward movement of the threaded cylinder (25), thereby increasing the compression force of the buffer spring (26) and pushing the scraper (17) to further press the tank wall. The residual mixed material is scraped off by rotation, and the buffer spring (26) buffers the reaction force of the hard mixed material at the same time. S4. Residual vibration removal and buffer protection: After the scraper (17) finishes scraping the wall, the operator drives the scraper (17) to retract and detach from the tank wall by starting the first drive motor (23), and then starts the vibration motor (19). The vibration motor (19) drives the scraper (17) to vibrate and remove the residual material on the surface. During the vibration process, the buffer spring (26) in the regulating groove (11) absorbs the vibration energy through the reciprocating motion of extension and retraction, reducing equipment damage.
