Description

Technical Field

[0001] This invention belongs to the field of corn planting technology, specifically a high-efficiency root-soil separation device based on corn stubble excavation. Background Technology

[0002] With the development of animal husbandry and the increasing demand for grain, corn has become the crop with the largest planting area and total output in my country. Northern regions, including Northeast China, are the main corn-producing areas. Corn stubble, as a byproduct of corn cultivation, is also increasing year by year. Corn stubble is rich in organic matter and trace elements, and also has a high calorific value, making it suitable for use as both organic fertilizer and raw material for biomass energy. 2 With the widespread implementation of conservation tillage, the corn stubble treatment method is the use of root-soil separation devices, which can separate the soil after the roots are dug up.

[0003] The existing root-soil separation device mainly consists of an excavation section, a stubble removal section, a roller separation section, and a vibrating conveyor separation section. However, when the soil is shaken off completely by vibrating the conveyor chain for a long time, the chain may become loose, which may cause the chain and gears to separate and derail. This not only reduces the conveying efficiency but also causes equipment failure due to derailment. Therefore, it needs to be improved. Summary of the Invention

[0008] Preferably, the surface of the limiting slide rod, the sliding block, and the inner wall of the first spring are slidably connected.

[0009] Preferably, the drive assembly includes a drive disc, a driven gear, a pneumatic cylinder, and a drive gear block; The drive disc is movably sleeved inside the support base and located in the middle of one side of the linkage bracket. The driven gear is fixedly sleeved on the surface of one end of the drive disc. The pneumatic cylinder is installed on the surface of the support base and located on one side of the top of the driven gear. The driving gear block is fixedly installed on the output end of the pneumatic cylinder.

[0010] Preferably, the protruding portion on the other side of the drive disc extends into the inner groove of the linkage bracket, and the protruding portion on the other side of the drive disc is slidably connected to the inner groove of the linkage bracket.

[0011] Preferably, the bottom of the driving gear engages with the surface of the driven gear.

[0012] Preferably, a shaking mechanism is provided on the top of the inner side of the tensioning block, and the shaking mechanism includes a shaking cam, a connecting rod and a transmission gear; The vibrating cam is movably sleeved on the top of the inner end of the tensioning block. The inner sides of the vibrating cam are fixedly sleeved together by a connecting rod. The transmission gear is fixedly sleeved on the outer end of the vibrating cam. There are two transmission gears, and the two transmission gears mesh with each other.

[0013] Preferably, the end of the vibrating push rod mechanism is connected to the vibrating cam on one side via a linkage mechanism, the linkage mechanism including a first transmission block, a second transmission block and a linkage component; The first transmission block is fixedly sleeved on the end of the vibrating push rod mechanism, the second transmission block is fixedly sleeved on the end of the vibrating cam, and the linkage component is movably sleeved between the first transmission block and the second transmission block.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordinated arrangement of tensioning and driving components, activates the driving component when the chain at the rod conveying mechanism becomes loose. This activates the linkage bracket and the tensioning components on both sides to move upward synchronously, causing the top of the tensioning component to press against the middle of the chain at the bottom of the rod conveying mechanism, thereby tightening the loose chain and preventing derailment. The high tension also greatly improves the conveying efficiency. This invention, through the coordination of structures such as a shaking mechanism and a linkage mechanism, allows the shaking top rod mechanism to be driven to rotate simultaneously with the rotation of the rod conveying mechanism. The linkage mechanism then drives the entire shaking mechanism to move synchronously downwards at the top of the tensioning assembly. Since the tensioning assembly is slidably connected to the inner side of the linkage bracket, the rotation of the shaking mechanism pushes the chain to shake, causing the tensioning assembly to be squeezed and pushed downwards. This effectively shakes the bottom of the chain while maintaining its tension, further improving the stability of the chain and gear connection. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 7 As shown, the present invention provides a high-efficiency root-soil separation device based on corn stubble excavation, including a frame 100, and further including: a rod conveying mechanism 500, which is disposed on one side of the frame 100, and a vibrating top rod mechanism 900 is installed in the middle of the inner side of the rod conveying mechanism 500; a tensioning mechanism 600, which is installed on the top of the frame 100 and located on both sides below the outer end of the rod conveying mechanism 500; wherein, the tensioning mechanism 600 includes a support base 610 fixedly installed on the top of one side of the frame 100, a linkage bracket 620 movably installed inside the support base 610, a tensioning component 630 slidably installed at the bottom of the chain on the outer side of the rod conveying mechanism 500 at the inner end of one side of the linkage bracket 620, and a drive component 640 located in the middle of one side of the linkage bracket 620 inside the support base 610.

[0020] By activating the drive assembly 640, the linkage bracket 620 and the tension assembly 630 can move up and down as a whole. When the tension assembly 630 is driven to move upward, the bottom of the chains on both sides of the rod conveyor mechanism 500 will be squeezed and tensioned to prevent the chains and gears from disengaging.

[0021] like Figure 1 As shown, a double-disc digging mechanism 200 is provided on the other side of the frame 100, a stubble-pulling mechanism 300 located on one side of the double-disc digging mechanism 200 is installed on the inner side of the frame 100, and a concave plate roller type root-soil separation mechanism 400 located between the stubble-pulling mechanism 300 and the rod conveying mechanism 500 is provided on the inner side of the frame 100.

[0022] Using the above scheme: First, when the frame 100 is moved to the working position, the double-disc digging mechanism 200 can be activated to dig the corn roots inside the soil. Then, the stubble-pulling mechanism 300 pulls and conveys the stubble to initially separate some of the broken soil. When it is conveyed to the concave roller type root-soil separation mechanism 400, the mixture of corn roots and soil can be squeezed, rubbed and broken up. Finally, the rod conveying mechanism 500 conveys and the shaking top rod mechanism 900 shakes, causing the broken soil remaining on the corn roots to fall off, thus achieving the effect of efficient root-soil separation.

[0023] like Figure 5 and Figure 6 As shown, the tensioning assembly 630 includes a tensioning block 631, a sliding block 632, a limiting slide bar 633, and a first spring 634; Tensioning block 631 is slidably installed on one end of the inner side of linkage bracket 620. Sliding block 632 is fixedly installed on the outer end of tensioning block 631 and located inside linkage bracket 620. Limiting slide rod 633 is fixedly installed on one side of linkage bracket 620 and located inside sliding block 632. The bottom of sliding block 632 is elastically connected to the inner wall of linkage bracket 620 through first spring 634.

[0024] By adopting the above scheme, due to the elastic force of the first spring 634, the sliding block 632 and the tensioning block 631 can be supported and fixed upward.

[0025] like Figure 5 and Figure 6 As shown, the surface of the limiting slide bar 633 is slidably connected to the inner wall of the sliding block 632 and the first spring 634.

[0026] The above solution, through the design of the limiting slide bar 633, can achieve the effect of synchronously limiting the up and down movement of the sliding block 632 and the tensioning block 631 and stretching the first spring 634.

[0027] like Figure 4 and Figure 5 As shown, the drive assembly 640 includes a drive disc 641, a driven gear 642, a pneumatic cylinder 643, and a drive gear block 644. The drive disc 641 is movably sleeved inside the support base 610 and located in the middle of one side of the linkage bracket 620. The driven gear 642 is fixedly sleeved on the surface of one end of the drive disc 641. The pneumatic cylinder 643 is installed on the surface of the support base 610 and located on one side of the top of the driven gear 642. The driving gear block 644 is fixedly installed on the output end of the pneumatic cylinder 643.

[0028] like Figure 4As shown, the protruding portion on the other side of the drive disc 641 extends into the inner groove of the linkage bracket 620, and the protruding portion on the other side of the drive disc 641 is slidably connected to the inner groove of the linkage bracket 620.

[0029] The above solution is adopted: when the driven gear 642 and the drive disk 641 are driven to rotate as a whole, the protruding part on the other side of the drive disk 641 will slide and connect in the inner groove of the middle of the linkage bracket 620, thereby achieving the effect of driving the linkage bracket 620 and the tensioning component 630 to move up and down as a whole.

[0030] like Figure 5 As shown, the bottom of the driving gear 644 meshes with the surface of the driven gear 642.

[0031] Using the above scheme: When the pneumatic cylinder 643 is activated, the output end of the pneumatic cylinder 643 will drive the entire movement of the active gear block 644, thereby causing the teeth at the bottom of the active gear block 644 to drive the teeth on the surface of the driven gear 642, thus achieving the effect of driving the driven gear 642 and the drive disc 641 to rotate as a whole, so as to smoothly drive the linkage bracket 620 to move in the future.

[0032] like Figure 3 and Figure 7 As shown, a shaking mechanism 700 is provided on the top of the inner side of the tensioning block 631. The shaking mechanism 700 includes a shaking cam 710, a connecting rod 720 and a transmission gear 730. The vibrating cam 710 is movably sleeved on the top of the inner end of the tensioning block 631. The inner sides of the vibrating cam 710 are fixedly sleeved together by the connecting rod 720. The transmission gear 730 is fixedly sleeved on the outer end of the vibrating cam 710. There are two transmission gears 730, and the two transmission gears 730 mesh with each other.

[0033] The above scheme is adopted: when the transmission gear 730 and the vibrating cam 710 on one side rotate as a whole, the teeth on the surface of the transmission gear 730 on one side will drive the teeth on the surface of the transmission gear 730 on the other side, thereby driving the transmission gear 730 and the vibrating cam 710 on the other side to rotate as a whole. Finally, the vibrating cams 710 on both sides of the outer end will rotate synchronously through the connecting rod 720, thereby realizing the pushing vibration of the outer chain of the rod conveying mechanism 500, which greatly improves the soil shaking effect.

[0034] like Figure 3 and Figure 7 As shown, the end of the vibrating push rod mechanism 900 is connected to the vibrating cam 710 on one side via a linkage mechanism 800. The linkage mechanism 800 includes a first transmission block 810, a second transmission block 820, and a linkage component 830. The first transmission block 810 is fixedly sleeved on the end of the vibrating push rod mechanism 900, the second transmission block 820 is fixedly sleeved on the end of the vibrating cam 710, and the linkage assembly 830 is movably sleeved between the first transmission block 810 and the second transmission block 820.

[0035] like Figure 3 and Figure 7 As shown, the linkage assembly 830 includes a linkage link 831, a telescopic cylinder 832, and a second spring 833; The two ends of the linkage 831 are movably sleeved with the ends of the first transmission block 810 and the second transmission block 820, respectively, and the inner end of the linkage 831 is provided with a telescopic cylinder 832, and the output end of the telescopic cylinder 832 is elastically connected to the inner cavity through a second spring 833.

[0036] The above solution is adopted: by designing the telescopic cylinder 832, when the vibrating cam 710 moves upward as a whole, the linkage component 830 squeezes the telescopic cylinder 832 to retract, thereby maintaining the transmission effect between the linkage link 831 and the first transmission block 810 and the second transmission block 820.

[0037] Working principle and usage process of this invention: First, once the control unit 1 has moved to the designated position, the double-disc digging mechanism 200 can be activated to dig up the corn roots in the soil. Then, the mixture of soil and corn roots can continue to move to one side through the stubble-pulling mechanism 300 for stubble-pulling, causing some broken soil to separate and fall. Then, it moves back to the concave roller type root-soil separation mechanism 400. At this time, the concave roller type root-soil separation mechanism 400 can be activated to squeeze and rub the mixture to break up the soil, achieving the purpose of soil separation. Finally, the corn roots and the remaining soil are transported by the rod conveying mechanism 500 and shaken and dropped by the shaking top rod mechanism 900, so that the soil is fully separated, achieving the purpose of efficient separation of corn roots and soil.

[0038] Afterwards, when the vibrating top rod mechanism 900 has been running for a long time and the chains on both sides of the rod conveying mechanism 500 become loose, the pneumatic cylinder 643 can be activated to push the active tooth block 644 to move. This causes the teeth at the bottom of the active tooth block 644 to drive the teeth on the surface of the driven gear 642, thereby driving the driven gear 642 and the drive disc 641 to rotate synchronously. Then, the protruding part on one side of the drive disc 641 slides in the inner groove in the middle of the linkage bracket 620, thereby driving the linkage bracket 620 and the tensioning block 631 to move upward as a whole until the chain is fully tightened. The meshing effect of the teeth can improve the accuracy of the lifting height and avoid excessive compression of the chain.

[0039] Subsequently, when the shaking top rod mechanism 900 continues to rotate to shake the entire rod conveying mechanism 500, the first transmission block 810 will rotate synchronously, so that the second transmission block 820 will be driven by the linkage component 830 to drive the shaking cam 710 and connecting rod 720 on one side to rotate synchronously. Then, through the meshing relationship of the transmission gear 730, the shaking cam 710 and connecting rod 720 on the other side can be driven to rotate simultaneously. Then, the end of the transmission gear 730 can press upward against the bottom chain part of the rod conveying mechanism 500, so as to greatly increase the shaking amplitude and improve the soil shaking efficiency. At this time, the rotation of the transmission gear 730 causes the end to press against the chains on both sides of the rod conveying mechanism 500, which will cause the tensioning block 631 and sliding block 632 to move downward and compress the first spring 634, which can buffer the shaking force of pressing upward against the rod conveying mechanism 500 and prevent it from loosening faster.
