Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to an agricultural straw mulching high stubble leaving machine. Background Art

[0002] At present, traditional farming methods often lead to rapid evaporation of soil moisture and a decrease in soil fertility. In order to overcome these drawbacks, agricultural experts have begun to explore more efficient farming techniques. Among them, the "stubble-leaving, less tillage or no-tillage, straw-covering throughout the process" technology came into being. This technology effectively reduces the evaporation of soil moisture and improves the soil's water retention capacity by retaining crop residues and covering the ground with straw. At the same time, the rotting of straw and returning it to the field can also increase soil organic matter and improve soil structure. The agricultural straw-covering high-stubble machine is the product of this technical concept. It can retain a higher stubble when harvesting crops and use mechanical means to cover the surface with straw, thereby achieving soil protection and improvement. In addition, the demand for soil protection is also an important factor in promoting the development of agricultural straw-covering high-stubble machines. With the continuous development of agricultural production, problems such as soil erosion and soil and water loss are becoming increasingly serious, posing a serious threat to the sustainable development of agriculture. The agricultural straw-covering high-stubble machine effectively reduces wind and water erosion of the soil and protects precious land resources through its unique operating method.

DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0056] See also Figure 1-Figure 10 An agricultural straw mulching high stubble machine provided in an embodiment of the present invention comprises a stubble machine housing 1, a traction connecting frame 3 and a power control box 4 are fixedly mounted on the stubble machine housing 1, and further comprises:

[0057] An L-shaped centralizing plate 9, the L-shaped centralizing plate 9 is located in the stubble machine housing 1 and is fixedly connected to the inner wall of the stubble machine housing 1, and a plurality of guide slots 10 are provided on the L-shaped centralizing plate 9;

[0058] and a stubble auxiliary mechanism, which is respectively connected to the stubble machine housing 1 and the L-shaped straightening plate 9 and is arranged close to the guide slot 10, wherein the stubble auxiliary mechanism includes a stubble cutting component and a straightening control component;

[0059] The stubble cutting assembly is connected to the stubble machine housing 1 and the L-shaped straightening plate 9 respectively, and the straightening control assembly is also connected to the stubble machine housing 1 and the L-shaped straightening plate 9 respectively, and is arranged close to the guide slot 10;

[0060] When the external traction equipment drives the stubble machine housing 1 and the L-shaped straightening plate 9 forward, the straw automatically enters the guide groove 10. Through the limiting operation of the guide groove 10 and the detection and straightening action of the straightening control component, the straw reaches the stubble cutting component in a vertical state for fixed-height cutting.

[0061] See also Figure 1-Figure 10 , further comprising: a protective baffle 7, the protective baffle 7 being detachably connected to the stubble machine housing 1, and a handle 8 being fixedly mounted on the protective baffle 7;

[0062] And an electric control indicator box 2, wherein the electric control indicator box 2 is fixedly mounted on the stubble machine housing 1 and is electrically connected to the stubble auxiliary mechanism.

[0063] It also includes: an adjustment frame 5, the adjustment frame 5 is connected to the stubble machine housing 1, and the number of the adjustment frames 5 is two, and the two adjustment frames 5 are respectively located on both sides of the stubble machine housing 1;

[0064] And a supporting roller 6, wherein the supporting roller 6 is rotatably connected to the adjusting frame 5.

[0065] When cutting and leaving stubble for straw, first, the whole equipment is connected to the external traction equipment through the traction connecting frame 3 to push the stubble machine housing 1 to move horizontally in the specified area, and the height of the support roller 6 can be adjusted through the arranged adjustment frame 5, so that the stubble machine housing 1 can roll on the ground while the support roller 6 is moving, thereby ensuring the stability of the equipment movement during the entire cutting process, wherein the adjustment frame 5 can adopt the existing adjustment technology, for example, by cooperating with the steel plate and the bolts, the adjustment frame 5 can be rotated a certain angle on the stubble machine housing 1, thereby changing the height of the support roller 6, and at the same time, the traction connecting frame 3 can also be in the form of adjustable height, so that the stubble machine housing 1 can move horizontally, which will not be described in detail here. After the connection with the external traction equipment is completed, the protective baffle 7 provided on the stubble machine housing 1 can be removed (when the stubble machine housing 1 is not in use, the protective baffle 7 can prevent the various components in the stubble machine housing 1 from being damaged). Then, as the stubble machine housing 1 moves in the designated stubble cutting area, the rows of straw will automatically enter the multiple guide slots 10 respectively, wherein the number of guide slots 10 is preferably two to four. Through the limiting operation of the guide slots 10 and the detection and straightening action of the straightening control component, the inclined straw can be straightened, so that the straw can reach the stubble cutting component in a nearly vertical state for fixed-height cutting, while the non-lodging straw will not be affected by the guide slots 10 and the straightening control component. The cutting is normally performed by the stubble cutting assembly, wherein, when the straw dumping direction is opposite to the forward movement direction of the stubble machine housing 1, as the stubble machine housing 1 and the L-shaped straightening plate 9 continue to move, when the straw gets closer and closer to the end of the guide slot 10, under the limiting effect of the guide slot 10, the end of the guide slot 10 will eventually straighten the inclined straw, so that the straw is cut in a nearly vertical state (at this time, the straw just reaches the vicinity of the stubble cutting assembly), and because the fallen straw is cut in a nearly vertical state, its height is approximately equal to that of the normal straw cutting, thereby ensuring the quality and effect of the straw stubble, and avoiding the breeding of bacteria due to the straw falling (the setting of the L-shaped straightening plate 9 itself can ensure batch The straw is successfully straightened and cut at a fixed height), and when the straw falling direction is the same as the forward moving direction of the stubble machine housing 1, the guide slot 10 cannot produce a limiting pushing effect on the fallen straw. At this time, under the detection action of the straightening control component, the straightening control component can push the fallen straw to the stubble cutting component in an approximately vertical state for cutting. Similarly, since the fallen straw is cut in an approximately vertical state, its height is approximately equal to that of normal straw cutting, thereby ensuring the quality and effect of straw stubble leaving, and the operation is simple. Especially for work sites with more straw lodging areas, the fallen straw can be smoothly stubble cut, and the straw cutting height can be ensured to be approximately equal, and at the same time, the straw in different cutting areas can be cut evenly.This is conducive to improving the quality and effect of straw cutting and stubble retention, and provides convenience for the staff.

[0066] In one embodiment of the present invention, see Figure 1-Figure 10 , the stubble cutting assembly comprises:

[0067] A cutting support 11, wherein the cutting support 11 is fixedly connected to the L-shaped straightening plate 9;

[0068] A cutting shaft 12, wherein the number of the cutting shaft 12 is at least one, and the plurality of cutting shafts 12 are connected by a transmission member 13, and the cutting shaft 12 passes through the cutting support 11 and is rotatably connected to the cutting support 11;

[0069] One of the cutting shafts 12 is also connected to the power control box 4;

[0070] And a cutting knife 25 , wherein the cutting knife 25 is fixedly mounted on the bottom end of the cutting shaft 12 and is disposed close to the guide slot 10 .

[0071] During the process of cutting the straw, the power equipment arranged in the power control box 4, such as a motor driving the cutting shaft 12 to rotate, and other power equipment (fan, etc.), can make the cutting shaft 12 rotate on the cutting support 11, and drive the cutting knife 25 to rotate, wherein the end of the cutting knife 25 is located below the end of the guide groove 10, so that when the straw reaches the end near the guide groove 10, the cutting knife 25 cuts the straw, and the height of the cutting knife 25 can be adjusted, thereby changing the height of the straw stubble. When multiple cutting shafts 12 are set, the cutting shafts 12 are connected by transmission members 13, wherein the transmission member 13 can adopt a belt drive structure to realize the synchronous rotation of multiple cutting knives 25 for cutting operations, which will not be elaborated here.

[0072] In one embodiment of the present invention, see Figure 1-Figure 10 , the righting control assembly comprises:

[0073] A straightening bracket 20, wherein the straightening bracket 20 is fixedly mounted on the L-shaped straightening plate 9;

[0074] A driving motor 19, wherein the driving motor 19 is fixedly connected to the straightening bracket 20, and a straightening shaft 18 is fixedly mounted on the output end of the driving motor 19, and a plurality of straightening rods 27 are evenly distributed on the straightening shaft 18;

[0075] A correction plate 29, the correction plate 29 is connected to the correction rod 27, and a plurality of sharp teeth 31 are distributed on the correction plate 29;

[0076] And a lodging detection unit, which is connected to the L-shaped straightening plate 9 and is arranged close to the guide groove 10, and the lodging detection unit is also electrically connected to the driving motor 19.

[0077] The lodging detection unit comprises:

[0078] A detector 22, wherein the number of the detectors 22 is multiple, and the multiple detectors 22 are all fixedly connected to the L-shaped centralizing plate 9 and are arranged close to the guide slot 10, and the detectors 22 are also electrically connected to the power control box 4 and the drive motor 19;

[0079] And an inclined monitoring roller 23, which is rotatably connected to the detector 22, wherein the heights of multiple inclined monitoring rollers 23 from the lowest end of the L-shaped straightening plate 9 are equal, and the distance between two adjacent inclined monitoring rollers 23 located on both sides of the guide groove 10 is less than the width of the guide groove 10.

[0080] It also includes: a damping detection tooth 21, the number of the damping detection tooth 21 is multiple, the multiple damping detection teeth 21 are evenly distributed in the guide slot 10, and the damping detection tooth 21 is also electrically connected to the power control box 4.

[0081] As the stubble machine housing 1 and the L-shaped straightening plate 9 move forward, the straw automatically enters the guide slot 10 (when the tilting direction of the fallen straw is consistent with the direction of forward movement of the equipment), the fallen straw will contact the tilting monitoring roller 23, and because the straw is in an inclined state, in the horizontal direction of the L-shaped straightening plate 9, the positions where the two adjacent tilting monitoring rollers 23 contact the fallen straw are not on the same horizontal plane (and, when the straw enters the guide slot 10 in a vertical state, the vertical straw will contact multiple tilting monitoring rollers 23 in sequence, then the adjacent tilting monitoring rollers 23 will rotate discontinuously, and the tilted straw will contact multiple tilting monitoring rollers 23 in sequence, And when the latter tilt monitoring roller 23 rotates, the former tilt monitoring roller 23 is also in a rotating state without interruption, so that the accuracy of the detection result can be further guaranteed by utilizing this difference), wherein a plurality of sensors are provided in the longitudinal direction of the tilt monitoring roller 23 and are arranged circumferentially on the tilt monitoring roller 23, and when two adjacent tilt monitoring rollers 23 detect that the positions of the straws are not on the same horizontal plane, the detector 22 controls the driving motor 19 to start, and drives the straightening shaft 18 to rotate rapidly (the rotation speed of the straightening shaft 18 is greater than the forward movement speed of the stubble machine housing 1), then the straightening shaft 18 drives the straightening rod 27 and the straightening plate 29 to rotate synchronously counterclockwise (such as Figure 4As shown in the figure, when the multiple sharp teeth 31 on the straightening plate 29 come into contact with the inclined straw, as the straightening rod 27 continues to rotate, the fallen straw can be pushed to rotate clockwise in the guide groove 10, so that the fallen straw is in a nearly horizontal state and reaches the cutting knife 25 to be cut. In addition, through the damping detection tooth 21 (which can be in the form of a plurality of pressure sensors at the bottom of the tooth), on the one hand, it can come into contact with the straw and generate a small thrust, especially for the straw whose inclination direction is opposite to the forward movement direction of the stubble machine housing 1. The straightening of the reversed straw has an auxiliary effect, especially for the fallen straw with a larger diameter. Under the detection effect of the damping detection tooth 21 on the two sides of the straw, it can detect whether there is a large deviation in the forward movement direction of the stubble machine housing 1 (it can also detect whether the straw is tilted), so that correction can be made in time. On the other hand, since the damping detection tooth 21 is also electrically connected to the power control box 4 (including the detector 22), the corresponding power equipment can be controlled. Please refer to the following content for details, and no further elaboration will be given here.

[0082] In one embodiment of the present invention, see Figure 1-Figure 10 , further comprising: a slide slot 28, wherein the slide slot 28 is provided on the straightening rod 1 27;

[0083] A second adjusting rod 30, one end of which passes through the first adjusting rod 27 and is inserted into the slide slot 28, and the other end of which is fixedly connected to the adjusting plate 29;

[0084] A limit baffle 36, the limit baffle 36 is fixedly mounted on the second straightening rod 30 and is slidably connected to the slide slot 28;

[0085] A return spring 35, wherein the return spring 35 is sleeved on the second straightening rod 30, wherein two ends of the return spring 35 are fixedly connected to the slide slot 28 and the limit baffle 36 respectively;

[0086] And a telescopic control component, which is connected to the straightening shaft 18 and the second straightening rod 30 respectively.

[0087] The telescopic control component comprises:

[0088] A telescopic accommodating sleeve 37, wherein the telescopic accommodating sleeve 37 is fixedly connected to the second adjusting rod 30, and a telescopic control member 33 is fixedly mounted on the telescopic accommodating sleeve 37, and the telescopic control member 33 is electrically connected to the detector 22;

[0089] A toggle slide post 34, wherein the toggle slide post 34 is inserted into the telescopic control member 33 and the telescopic accommodation sleeve 37, wherein the telescopic control member 33 can drive the toggle slide post 34 to slide in the telescopic control member 33;

[0090] And a support plate 24, the support plate 24 is fixedly connected to the stubble machine housing 1, and a detection control cam 32 is fixedly installed on the support plate 24, the detection control cam 32 is sleeved on the straightening shaft 18, and the detection control cam 32 is also slidably connected to the toggle slide post 34.

[0091] It also includes: a feeding support rod 14, the feeding support rod 14 is fixedly connected to the L-shaped straightening plate 9, and a distribution beam 15 is fixedly installed on the feeding support rod 14;

[0092] An air control branch pipe 16, wherein the number of the air control branch pipes 16 is multiple, and the multiple air control branch pipes 16 are all connected to the power control box 4;

[0093] And the feeding air duct 17, the number of the feeding air duct 17 is multiple, the multiple groups of the feeding air duct 17 are respectively connected with the multiple air control branch pipes 16, and are respectively located above the multiple guide slots 10, and the feeding air duct 17 is also provided with a nozzle 26.

[0094] In the process of stubble cutting of straw, the fan in the power control box 4 will blow air into the multiple wind control branch pipes 16 through the hose, and the high-pressure air will enter the feeding air duct 17 through the groove opened on the distribution beam 15, and spray in the direction of the end of the guide slot 10 through the nozzle 26, which can ensure that after the cutting is completed, the straw cut above the guide slot 10 moves backward under the action of wind force and the continuous forward movement of the stubble machine housing 1, and finally separates from the stubble machine housing 1 and covers the ground. In addition, since the damping detection tooth 21 is also electrically connected to the power control box 4, when the tilt monitoring roller 23 detects that the tilt direction of the fallen straw is consistent with the forward movement of the stubble machine housing 1 When the direction is opposite, in order to avoid that the straw is still in a large tilt state when being cut under the action of wind force, thereby affecting the effect of contour cutting, at this time, under the joint control of the damping detection tooth 21 and the detector 22, the wind force of the wind outlet of the corresponding straightening rod 27 above the corresponding guide slot 10 can be reduced, so as to avoid further increasing the degree of straw lodging. For the lodged straw in the same forward movement direction as the stubble machine housing 1, first, the detector 22 will control the telescopic control member 33 above the corresponding guide slot 10 to start, wherein the telescopic control member 33 can be in the form of a cylinder, which can push the toggle slide column 34 to move in the direction of the detection control cam 32, and cooperate with the detection control cam The side wall of the wheel 32 is in contact with the side wall of the wheel 32 (when the straw in the guide groove 10 is in a non-lodging state, the toggle slide post 34 is located in the telescopic control member 33 and the telescopic accommodating sleeve 37, and does not contact the detection control cam 32). As the straightening shaft 18 drives the straightening rod 27 to rotate, the toggle slide post 34 will rotate on the detection control cam 32. At this time, under the pushing action of the detection control cam 32, the straightening rod 20 30 can be extended out of the straightening rod 27, and the reset spring 35 is in a gradually compressed state, so that as the straightening rod 27 rotates, the total length that the straightening plate 29 can reach can be increased (the straightening rod 29 can be adjusted according to the degree of inclination of the straw detected by the inclination monitoring roller 23). The extension and retraction of the two 30 is controlled. For example, when the tilt monitoring roller 23 detects that the tilt degree of the straw is large, in order to ensure that the straw is straightened to a nearly vertical state, the length of the straightening plate 29 can be increased to ensure that the straw is fully straightened. No further details are given here. When the toggle slide post 34 reaches the top of the convex part of the detection control cam 32, the straightening action of the straw is completed. In addition, sensors can be provided on the two side walls of the convex part of the detection control cam 32.
