Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of deep ploughing and fertilization, in particular to a deep ploughing and fertilization integrated machine for crops. BACKGROUND

[0002] In the agricultural tillage system, the soil deep ploughing operation specifically refers to the agronomic operation of implementing the crushing treatment of the plough bottom layer at 5-15 cm below the tillage layer by means of the deep ploughing machinery. The technology can effectively break the soil hardening phenomenon, and then realize the depth expansion of the tillage layer, so as to build a loose and permeable soil environment for the growth of crop roots. At the same time, the breaking of the plough bottom layer can significantly improve the pore condition of the soil, optimize the soil permeability, and on this basis, improve the coordinated control ability of the soil to water, nutrients, air and heat, thereby increasing the soil field water holding capacity and enhancing the water guarantee capacity for crop growth.

[0003] The soil weeding technology is a key link in farmland management, and its core function is to reduce the number of weed populations by physical or biological means, so as to reduce the intensity of competition between weeds and crops for soil nutrient resources, effectively improve the absorption and utilization rate of crops for soil nutrients such as nitrogen, phosphorus and potassium, and reduce the invalid consumption and waste of nutrient resources.

DETAILED DESCRIPTION

[0033] The following will be described with reference to the accompanying drawings Figures 1 to 7 The embodiments of the present application will be described in detail. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0034] First embodiment:

[0035] A deep type crop weeding and fertilizing integrated machine, comprising a mounting frame 1 and a plurality of fertilizer conveying pipes 2, the front part of the mounting frame 1 is connected with the traction part of an external tractor, and a fertilizer bin 29 is further arranged on the mounting frame 1, the fertilizer bin 29 is provided with a material conveying device 30 for distributing and conveying the fertilizer into each fertilizer conveying pipe 2; a plurality of support shells 3 and elastic support mechanisms are arranged at the bottom of the mounting frame 1, a plough share 4 is hingedly connected in the support shell 3, and the top end of the plough share 4 is connected with the elastic support mechanism; the elastic support mechanism comprises a hinged shaft 27 arranged on the plough share 4, the hinged shaft 27 is rotationally connected with the support shell 3, an L-shaped rod 7 is fixedly connected on the hinged shaft 27, and one end of the L-shaped rod 7 is connected with the mounting frame 1 through a tension spring 8; plough wings 26 are arranged on both sides of the support shell 3; during the driving of the tractor, the plough share 4 advances with the tractor and ploughs the soil, and the plough wings 26 are located at the rear part of the plough share 4, so that the ploughing effect is improved through the synergistic effect of the plough share 4 and the plough wings 26, and the lateral stability during the ploughing process is ensured.

[0036] It should be noted that, during the ploughing process of the plough share 4, when the plough share 4 collides with hard obstacles such as stones in the soil, the plough share 4 rotates and is retracted into the support shell 3 for buffering, and at the same time, the tension spring 8 is stretched, so as to prevent the plough share 4 from being deformed, broken or damaged due to excessive instantaneous impact force.

[0037] The output end of the fertilizer conveying pipe 2 is provided with an electromagnetic pinch valve, the electromagnetic pinch valve is fixed on the back of the support shell 3, the electromagnetic pinch valve is provided with a mechanical sealing driving part, and the mechanical sealing driving part is linked with the plough share 4; in the ploughing process of the plough share 4, the fertilizer conveying pipe 2 continuously performs the fertilization operation, when the plough share 4 abuts against the hard obstacle, the plough share 4 rotates and is received in the support shell 3, the plough share 4 abuts against the mechanical sealing driving part to make the electromagnetic pinch valve seal, that is, when the device encounters the hard obstacle and cannot move, the fertilization is automatically stopped, and the local overfertilization is prevented to cause the resource waste.

[0038] When the plough share 4 abuts against the hard obstacle, under the action of the reaction force, the plough share 4 rotates around the hinge shaft 27 and is received in the support shell 3, in the movement process, the plough share 4 abuts against the mechanical sealing driving part to make the electromagnetic pinch valve seal; that is, when the plough share 4 encounters the hard obstacle (such as rock) that cannot be overcome during the ploughing operation of the device, the above linkage mechanism is started immediately, the fertilization system is automatically terminated, the design can effectively avoid the phenomenon that the fertilization amount in a local area exceeds the threshold value due to the stop of the device, thereby reducing the invalid loss of the fertilizer resource, and meets the technical specification of precision fertilization and the resource-saving operation requirement.

[0039] The electromagnetic pinch valve comprises a valve body 10, an expansion cavity 11 and an expansion capsule 12, when the air pressure in the expansion cavity 11 rises or falls, the expansion capsule 12 expands or shrinks, so that the size of a fertilization passage 31 in the valve body 10 is adjusted, that is, the fertilization flow is adjusted, the side, close to the plough share 4, of the valve body 10 is provided with a piston cylinder 13, and the expansion cavity 11 and the piston cylinder 13 are connected with each other through a flow port 28.

[0040] A piston 14 is slidingly fitted in the piston cylinder 13, and when the piston 14 slides in the piston cylinder 13, the air pressure inside the inflation cavity 11 can be adjusted, that is, the size of the fertilization channel 31 can be adjusted; a magnet 15 is installed on the piston 14, and an electromagnet 16 is installed on the side of the piston 14 close to the share 4 in the piston cylinder 13; the magnet 15 and the electromagnet 16 are magnetically repulsive, the flow valve 6 is electrically connected with the electromagnet 16, and a compression spring 17 is installed on the other side of the piston 14; in the technical scheme of the embodiment, the device has the function of quickly adjusting the fertilization flow according to the actual operation requirements, and the core adjustment mechanism is as follows: by adjusting the input current intensity of the electromagnet 16, the magnetic field intensity generated by the electromagnet 16 can be changed; since the magnet 15 and the electromagnet 16 are in the same-pole opposite configuration state, the magnetic repulsion force between the two will change synchronously with the change of the magnetic field intensity of the electromagnet 16, the change of the magnetic repulsion force will adjust the driving force formed on the piston 14, under the cooperation of the driving force and the piston 14 and the compression spring 17, the piston 14 realizes accurate position control, and the position change of the piston 14 will directly change the annular flow cross-sectional area formed between the piston 14 and the inner wall of the fertilization channel 31, that is, by changing the diameter of the fertilization channel 31, the adjustment of the fertilization medium flow resistance is achieved, and finally the on-demand adjustment of the fertilization flow is realized.

[0041] The mechanical sealing driving part is a trigger rod 18, one end of the trigger rod 18 is fixed on the piston 14, and the other end of the trigger rod 18 extends out of the piston cylinder 13 and corresponds to the back of the share 4.

[0042] When the share 4 is working in the soil scarification process and butts against a hard obstacle, the share 4 rotates and is retracted into the supporting shell 3, the back of the share 4 butts against the trigger rod 18, the piston 14 moves towards the valve body 10, the air pressure inside the inflation cavity 11 increases, the inflation bag 12 expands and seals the fertilization channel 31, that is, during the plowing process of the device, when the share 4 touches an unovercome hard obstacle and causes the device to stop running, the fertilization system automatically stops working, and the phenomenon of fertilization amount exceeding the threshold value in the local area caused by the stop of the device is effectively avoided.

[0043] The support shell 3 is provided with an exciter 5, and the fertilizer delivery pipe 2 is provided with a flow valve 6, both of which are electrically connected with the flow valve 6; the mounting frame 1 is provided with a sensing mechanism for detecting the rotation of the plough share 4, which is electrically connected with the exciter 5, and the sensing mechanism is a trigger button 9 arranged at the bottom of the mounting frame 1, the position of which corresponds to the other end of the L-shaped rod 7, and the trigger button 9 is electrically connected with the exciter 5; the device is provided with an automatic control system, which takes a micro control unit (such as a single-chip microcomputer) as a core control module; during the ploughing (soil deep ploughing) operation of the plough share 4, when the plough share 4 is in contact with a hard obstacle in the soil, the plough share 4 is retracted into the support shell 3; during the movement, the L-shaped rod 7 linked with the plough share 4 rotates and swings, and the L-shaped rod 7 presses the trigger button 9; the electrical signal of the trigger button 9 is transmitted to the control system through a signal transmission line; after receiving the trigger signal, the control system sends a start control instruction to the exciter 5, and finally realizes the start control of the exciter 5; during the specific use, the trigger button 9 can be replaced by a rotation sensor, and the installation position of the rotation sensor matches the hinged shaft 27; when the L-shaped rod 7 rotates and swings, the rotation sensor sends a signal to the control system, and the exciter 5 starts.

[0044] The support shell 3 is provided with an obstacle removing auxiliary mechanism, which includes a stop body 19 arranged on the support shell 3, and the front end of the stop body 19 is provided with a protrusion 20.

[0045] The working principle of the device is as follows: during the ploughing operation of the device, when the plough share 4 is in contact with a hard obstacle such as a stone in the soil, the plough share 4 rotates and is retracted into the support shell 3 for buffering (at the same time, the L-shaped rod 7 rotates to stretch the tension spring 8), so as to prevent the deformation and fracture of the plough share 4 caused by excessive instantaneous impact force; if the plough share 4 touches a hard obstacle that cannot be overcome, causing the device to stop running, the plough share 4 will be completely retracted into the support shell 3, and the back of the plough share 4 abuts against the trigger rod 18, the piston 14 moves towards the valve body 10, the inflatable bag 12 expands and closes the fertilizer delivery channel 31, effectively avoiding the phenomenon that the fertilizer amount in a local area exceeds the threshold value due to the stop of the device, thereby reducing the invalid loss of fertilizer resources.

[0046] At the same time, the L-shaped rod 7 rotates to abut against the trigger button 9, the trigger button 9 sends an electrical signal to the control system, the control system controls the exciter 5 to start, and after the exciter 5 starts, the vibration energy is transmitted to the plough share 4, so that the device operates under the working condition of the vibration of the plough share 4, thereby more easily realizing the pushing or ploughing operation of the obstacle.

[0047] In addition, by the structural configuration of the abutment body 19 and the protrusion 20, the obstacle removal operation of the share 4 can be effectively assisted. Since the protrusion 20 adopts a local protrusion structure design, when contacting the obstacle, the contact area of the obstacle at the protrusion 20 is small, the pressure borne by the obstacle at this position is larger, a local concentrated load can be formed, and the vibration operation effect of the share 4 can be combined to significantly improve the breaking and removal efficiency of the obstacle, thereby facilitating the continuity of the soil deep tillage operation.

[0048] During the fertilization operation of the device, if the fertilizer conveying pipe 2 is blocked due to material caking, impurity accumulation or other reasons, the flow valve 6 can monitor the material conveying flow in the pipe in real time. When it is detected that the material conveying flow is lower than the preset threshold, the control system controls the electromagnetic iron 16 to be powered off. At this time, the magnetic repulsion force between the electromagnetic iron 16 and the magnet 15 disappears, the compression spring 17 releases the elastic potential energy and abuts against the piston 14, the piston 14 is displaced to the side away from the valve body 10, the expansion capsule 12 is contracted, the effective flow cross section of the fertilization channel 31 is rapidly expanded to the maximum state, the material flow space is increased, the flow resistance is reduced, the fertilizer conveying pipe 2 is quickly dredged, and the continuous and stable operation of the fertilization system is ensured.

[0049] Second embodiment:

[0050] Based on the first embodiment, the obstacle removal assisting mechanism includes an obstacle breaking knife 21 and a guide groove 32. The guide groove 32 is arranged on the side wall of the support shell 3. The guide clamping block 33 is fixedly connected to the obstacle breaking knife 21 and is in sliding fit with the guide groove 32. The elastic sheet 34 is arranged in the guide groove 32 on the side of the guide clamping block 33. The obstacle breaking knife 21 can slide along the guide groove 32.

[0051] The support shell 3 is provided with a sliding groove 22, and the share 4 is provided with a guide rod 23 in sliding fit with the sliding groove 22. When the share 4 rotates, the guide rod 23 slides in the sliding groove 22, thereby improving the stability during rotation.

[0052] The support shell 3 is rotatably connected with a cam 24 located at the back of the share 4. The cam 24 is rotatably connected with a connecting rod 25, and the other end of the connecting rod 25 is hingedly connected with the guide rod 23. Figure 3 According to the above, in the initial state, the obstacle breaking knife 21 is in the contracted state. When the cam 24 rotates clockwise, the obstacle breaking knife 21 slides to the right along the sliding groove 22, that is, the obstacle breaking knife 21 is extended, and at the same time, the elastic sheet 34 is compressed. When the cam 24 rotates counterclockwise, the elastic sheet 34 abuts against the obstacle breaking knife 21 to slide reversely and reset.

[0053] It should be noted that in the soil environment with dense root and stem sundries such as forest land, the soil plowing operation often faces great resistance, and the conventional operation mode is prone to jamming phenomenon, resulting in low operation efficiency; the device in this embodiment expands the function based on the basic structure of the first embodiment, and shows good adaptability when dealing with such complex working conditions: when the share 4 collides with the tree roots existing in the soil during the operation (taking the structure shown in Figure 3 When the share 4 rotates under the reaction force of the tree roots and is received into the support shell 3, at the same time, the guide rod 23 linked with the share 4 slides and displaces to the left side along the sliding groove 22, and through the transmission action of the connecting rod 25, the cam 24 is driven to rotate in the clockwise direction. The cam 24 abuts against the barrier cutter 21 through its profile curved surface during rotation, so that the barrier cutter 21 extends to the working position.

[0054] On this basis, combined with the cooperative working mechanism of the exciter 5, the vibration energy generated by the exciter 5 is transmitted to the barrier cutter 21, so that the barrier cutter 21 is in a high-frequency vibration working state. The barrier cutter 21 cuts the tree roots under the vibration working condition, significantly improving the efficiency of cutting the tree roots, and thus improving the continuity and operation efficiency of the soil plowing operation as a whole.

[0055] Third embodiment:

[0056] Based on the first embodiment or the second embodiment, the exciter 5 is electrically connected with the flow valve 6; the fertilizer conveying pipe 2 in this embodiment is a hard pipe, such as a metal pipe. During the use of the device, when the fertilizer conveying pipe 2 is blocked, the flow valve 6 detects that the conveying amount is reduced, the fertilizer conveying channel 31 is automatically adjusted to the maximum, and the control system controls the exciter 5 to start, so that the fertilizer conveying pipe 2 can be vibrated to assist the material in the fertilizer conveying pipe 2 to be discharged, achieving the effect of rapid dredging.

[0057] In this embodiment, the fertilizer conveying pipe 2 adopts a rigid pipe structure design, and can be specifically a hard pipe body such as a metal pipe. During the fertilizer application operation of the device, if the fertilizer conveying pipe 2 is blocked, the flow valve 6 will monitor the conveying flow of the material in the pipe in real time. When it is detected that the conveying amount is lower than the preset threshold, the electromagnet 16 is de-energized to automatically adjust the fertilizer conveying channel 31 to the maximum, and at the same time, the control system controls the exciter 5 to start. The vibration energy generated by the exciter 5 is transmitted to the fertilizer conveying pipe 2, and the inertia separation effect between the materials generated by the vibration is utilized, so that the fertilizer conveying pipe 2 is rapidly dredged, and the continuity of the fertilizer application operation is ensured.
