Description

Technical Field

[0001] The present invention relates to the technical field of knife rollers, and more particularly to a knife roller for a rod pulling machine. Background Art

[0002] Tobacco stalks are the largest by-product of tobacco production, with an annual output of about 4.5 million tons. As a special by-product of economic crops, tobacco stalks are not suitable for feed and cannot be directly returned to the fields because they contain nicotine and carry tobacco pathogens. Therefore, tobacco stalks are generally pulled out using a stalk puller and crushed for use as raw materials for biomass energy or polymer materials.

[0003] Among them, the patent with publication number CN205161164U discloses a flue-cured tobacco stem pulling machine, comprising a frame, two support plates for rotating roller cutter shafts are symmetrically arranged in the middle of the frame, a rotating roller cutter transmission shaft is arranged between the two support plates for rotating roller cutter shafts, a rotating roller cutter triangular cutter holder is arranged on the rotating roller cutter transmission shaft, and a blade is installed on the rotating roller cutter triangular cutter holder; a bearing seat support platform is arranged on one side of the frame, a transmission mechanism is arranged on the bearing seat support platform, and an adjustable depth device is arranged on the other side of the frame;

[0004] When this structure is in use, the triangular tool holder and the blade of the rotating roller cutter are rotated, and the gear transmission system formed by the first transmission gear and the second transmission gear in the intermediate transmission system changes the rotation direction. Then, the chain transmission formed by the second transmission sprocket and the rotating roller cutter transmission (without changing the rotation direction) sprocket finally causes the rotating roller cutter to rotate in the opposite direction to pull out the tobacco stems in the tobacco field. However, when this structure is in use, since the tobacco stems have high mechanical properties such as compression resistance, shear strength and bending strength, it is not easy to constrain the tobacco stems together for pulling out, and the soil crushing ability is relatively low, which affects subsequent planting. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rod pulling machine knife roller, which is intended to solve the problems raised in the above-mentioned background technology.

[0006] The present invention provides the following technical solution: a blade roller of a rod pulling machine, comprising a limit plate, and soil pulling and crushing components are arranged on both sides of the limit plate;

[0007] The soil removal and crushing assembly includes a cross bar arranged on one side of the bottom of the limiting plate, and a plurality of support plates are installed at both ends of the cross bar through flanges, and a plurality of elastic tie bars are distributed between the two support plates, and the cross-sectional shape of each of the elastic tie bars is spiral;

[0008] A plurality of connecting plates are mounted on the crossbar via flanges, a plurality of turning knives are mounted on the connecting plates via bolts, and each turning knife is provided with an arc cut;

[0009] It can be seen that in the above technical solution, when the cross bar rotates, it can also drive the support plate and the elastic tie rod to rotate. The elastic tie rod rotates to roll up the tobacco rod and constrain it together to improve the efficiency and effect of pulling out the rod. At the same time, when the elastic tie rod contacts the tobacco rod, the elastic tie rod is deformed by force and pulls the tobacco rod when it is elastically reset by the elastic tie rod itself. With the traction force when the support plate rotates, it is easy to pull the tobacco stem out of the soil, and the rotation of the turning knife breaks the soil, which is easy for subsequent planting.

[0010] Optionally, in a possible implementation, an extension tube is fixedly provided at the bottom of the limit plate, the extension tube is communicated with the limit plate, a protection box is fixedly provided at the bottom of the extension tube, a worm is rotatably connected in the extension tube, a worm wheel is provided at one side of the bottom of the worm, the worm wheel is located in the protection box, the worm wheel is meshed with the worm, a first rotating shaft is fixedly provided on the worm wheel, the first rotating shaft passes through the protection box and extends to the end of the cross bar;

[0011] It can be seen that in the above technical solution, the second rotating shaft is driven to rotate by an external motor, and when the second rotating shaft rotates, it drives the worm to rotate, and then the worm wheel and the first rotating shaft rotate. When the first rotating shaft rotates, it drives the cross bar, the connecting plate and the turning knife to rotate, turning the roots out of the soil.

[0012] Optionally, in a possible implementation, a first support rod frame is provided on one side of the surface of the limit plate, and a second support rod frame is provided on the other side of the surface of the limit plate, the first support rod frame is slidably connected with a position-adjustable support oblique rod, the bottom of the support oblique rod is rotatably connected with a support wheel for support, one end of the second support rod frame is rotatably connected with a shift tooth through an axle pin, and a torsion spring is sleeved on the axle pin, a reinforcement block is fixedly provided at the bottom of the shift tooth, the vertical cross-section of the reinforcement block is arc-shaped, a second rotating shaft is fixedly provided at the top of the worm, and the second rotating shaft is rotatably connected with the limit plate;

[0013] It can be seen that in the above technical solution, the support plate and the support wheel are used as support points, which makes it easy for the turning knife and the elastic tie rod to contact the ground, and convenient for the turning knife and the elastic tie rod to rotate to pull out the stems and crush the soil. At the same time, the support wheel can be adjusted to the appropriate position and angle on the first support rod frame through the supporting diagonal rod, and then the angle of the support wheel can be easily adjusted through the bolt to realize the function of adjusting the level of the turning knife and the elastic tie rod, thereby improving the pulling and crushing effects.

[0014] Technical effects and advantages of the present invention:

[0015] 1. The present invention uses the support plate and the support wheel as the support points, which makes it easy for the turning knife and the elastic tie rod to contact the ground, and convenient for the turning knife and the elastic tie rod to rotate to pull out the stems and crush the soil. At the same time, the support wheel can be properly adjusted in position and angle on the first support rod frame through the support inclined rod, and then the angle of the support wheel can be easily adjusted by the bolt to achieve the function of adjusting the level of the turning knife and the elastic tie rod, thereby improving the pulling and crushing effects;

[0016] 2. When the first rotating shaft of the present invention rotates, it drives the cross bar, the connecting plate and the turning knife to rotate, and turns the rhizome out of the soil. When the cross bar rotates, it can also drive the supporting plate and the elastic tie rod to rotate. The elastic tie rod rotates to roll up the tobacco rod, so that it is bound together, so as to improve the efficiency and effect of pulling out the rod;

[0017] 3. When the elastic tie bar contacts the tobacco stem, the elastic tie bar is deformed by force and pulls the tobacco stem through its own elastic reset. The traction force when the support plate rotates makes it easy to pull the tobacco stem out of the soil, and the rotation of the turning knife breaks the soil, which is easy for subsequent planting.

[0018] To sum up, through the corresponding coordinated use of various structures, the support wheel can be adjusted to the appropriate position and angle on the first support rod frame through the supporting diagonal rod, and then the angle of the support wheel can be easily adjusted through the bolt to realize the function of adjusting the level of the turning knife and the elastic tie rod, thereby improving the rod pulling and soil crushing effects. The elastic tie rod rotates to reel in the tobacco rod and constrains it together to improve the rod pulling efficiency and effect. The elastic tie rod is deformed by force and pulls the tobacco rod when it is elastically restored by the elastic tie rod itself. The traction force when cooperating with the rotation of the support plate makes it easy to pull the tobacco rod out of the soil, and the turning knife rotates to crush the soil, which is convenient for subsequent planting.

[0029] As attached Figure 1 - Figure 7 The blade roller of a rod pulling machine shown in the figure has a pulling and crushing soil component set on the limit plate 1. Through the corresponding coordinated use of various structures, the support wheel 15 can be adjusted to a proper position and angle on the first support rod frame 13 through the supporting inclined rod 14. Then, the angle of the support wheel 15 can be easily adjusted through the bolt to achieve the function of adjusting the level of the turning knife 6 and the elastic tie rod 4, thereby improving the rod pulling and soil crushing effect. The elastic tie rod 4 rotates to reel the tobacco rod and constrain it together to improve the rod pulling efficiency and effect. The elastic tie rod 4 is deformed by force and pulls the tobacco rod when it is elastically reset by the elastic tie rod 4 itself. The traction force when cooperating with the rotation of the support plate 3 makes it easy to pull the tobacco rod out of the soil, and the turning knife 6 rotates to crush the soil, which is easy for subsequent planting, and the specific structure of the component is set as follows;

[0030] The soil removal and crushing assembly includes a cross bar 2 arranged on one side of the bottom of the limit plate 1, and a plurality of support plates 3 are installed at both ends of the cross bar 2 through flanges. A plurality of elastic tie bars 4 for pulling the rods are distributed between the two support plates 3, and the cross-sectional shape of each elastic tie bar 4 is spiral.

[0031] A plurality of connecting plates 5 are mounted on the crossbar 2 through flanges, and a plurality of turning knives 6 are mounted on the connecting plates 5 through bolts, and each turning knife 6 is provided with an arc cutout 7;

[0032] An extension tube 8 is fixedly provided at the bottom of the limit plate 1, and the extension tube 8 is connected to the limit plate 1. A protection box 9 is fixedly provided at the bottom of the extension tube 8. A worm 10 is rotatably connected in the extension tube 8. A worm wheel 11 is provided at one side of the bottom of the worm 10. The worm wheel 11 is located in the protection box 9. The worm wheel 11 meshes with the worm 10. A first rotating shaft 12 is fixedly provided on the worm wheel 11. The first rotating shaft 12 passes through the protection box 9 and extends to the end of the cross bar 2.

[0033] A first support rod frame 13 is provided on one side of the surface of the limiting disk 1, and a second support rod frame 16 is provided on the other side of the surface of the limiting disk 1. A position-adjustable support oblique rod 14 is slidably connected to the first support rod frame 13, and a support wheel 15 for support is rotatably connected to the bottom of the support oblique rod 14. One end of the second support rod frame 16 is rotatably connected to a shifting tooth 17 through an axle pin, and a torsion spring 19 is sleeved on the axle pin. A reinforcing block 18 is fixedly provided at the bottom of the shifting tooth 17, and the vertical cross-section of the reinforcing block 18 is arc-shaped. A second rotating shaft 20 is fixedly provided on the top of the worm 10, and the second rotating shaft 20 is rotatably connected to the limiting disk 1.

[0034] When using the above structure, the staff installs the device on the rod pulling machine, with the support plate 3 and the support wheel 15 as the support points, so that the turning knife 6 and the elastic tie rod 4 are easy to contact with the ground, and the turning knife 6 and the elastic tie rod 4 are convenient to rotate to pull the stems and crush the soil. At the same time, the support wheel 15 can be adjusted to a proper position and angle on the first support rod frame 13 through the support inclined rod 14. After that, the angle of the support wheel 15 can be easily adjusted by bolts to achieve the function of adjusting the level of the turning knife 6 and the elastic tie rod 4, thereby improving the rod pulling and soil crushing effects;

[0035] When pulling out the stem, the second shaft 20 is driven to rotate by an external motor. When the second shaft 20 rotates, it drives the worm 10 to rotate, and then the worm wheel 11 and the first shaft 12 rotate. When the first shaft 12 rotates, it drives the cross bar 2, the connecting plate 5 and the turning knife 6 to rotate, and the roots are turned out of the soil. When the cross bar 2 rotates, it can also drive the support plate 3 and the elastic tie rod 4 to rotate. The elastic tie rod 4 rotates to reel in the tobacco stem and constrain it together to improve the efficiency and effect of pulling out the stem. At the same time, when the elastic tie rod 4 contacts the tobacco stem, the elastic tie rod 4 is deformed by force and pulls the tobacco stem when it is elastically reset by the elastic tie rod 4 itself. With the traction force when the support plate 3 rotates, it is easy to pull the tobacco stem out of the soil, and the turning knife 6 rotates to break the soil, which is easy for subsequent planting.

[0036] Different from the prior art, the present application discloses a knife roller of a rod pulling machine, which can be appropriately adjusted in position and angle on the first support rod frame 13 through the support wheel 15 and the support diagonal rod 14. Then, the angle of the support wheel 15 can be easily adjusted through bolts to achieve the function of adjusting the level of the turning knife 6 and the elastic tie rod 4, thereby improving the rod pulling and soil crushing effects. The elastic tie rod 4 rotates to reel in the tobacco rods and constrains them together to improve the rod pulling efficiency and effect. When the elastic tie rod 4 is deformed by force and elastically reset by the elastic tie rod 4 itself, the tobacco rod is pulled. In combination with the traction force when the support plate 3 rotates, the tobacco rod is easily pulled out of the soil, and the turning knife 6 rotates to crush the soil, which is convenient for subsequent planting.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
