Description

Technical Field

[0001] The invention relates to the technical field of agricultural equipment, in particular to a soil moisture control corn furrowing device. Background Art

[0002] The corn ridge-furrow planting mode enhances the stability of water supply by adjusting the vertical distribution of soil moisture, especially in the northern dryland agricultural areas where water resources are scarce. Ridge-forming combined with surface covering technology can not only increase soil moisture content and ground temperature, but also effectively utilize limited rainfall resources to improve corn drought resistance and yield. The existing application number is CN202210528738.X, which discloses a ditching, ridging and shaping device. The patent document discloses a method of using a first ridging blade, a second ridging blade, a first shaping plate and a second shaping plate in combination to act on the surface of the ditch and the ridge platform to ensure the density and consistency of the ridging and shaping. Specifically, the device moves with the tractor and, under the action of the power output shaft of the tractor, the rotary tiller rotates with the rotary tiller shaft to rotary till the field, and then the ditching device digs the ditch to give the ditch a holding and delay effect. At the same time, the first ridging mechanism and the second ridging mechanism cooperate to rotate to achieve the field ridging operation. The ridges formed after the ridging device is ridged are then accurately shaped by the first shaping plate and the second shaping plate to form ridges with high consistency and density. During the ridging and shaping, the hydraulic cylinder system applies a continuous downward pressure to the second fixed beam through the connecting beam, and continuously applies a downward pressure to the ridging device and the shaping device to ensure the consistency and density of the ridges after ridging and shaping. However, when using the technical solution in the above-mentioned patent document, the first ridging blade, the second ridging blade, the first shaping plate and the second shaping plate need to be respectively located on both sides of the ridge platform, so that the equipment needs to cover the top of the ridge platform to carry out operations; in actual use, due to the limitation of its operation mode, it is difficult to carry out ridge and furrow shaping operations on the soil surface of planted crops; from the perspective of coping with drought conditions, in the northwest region of my country, years with low annual precipitation may experience sudden special climatic conditions of severe drought, and the equipment cannot play an effective role in such circumstances, and cannot meet the needs of shaping ridges and furrows under such drought stress, which limits its applicability in drought response scenarios in the region.

[0007] Furthermore, an elastic water storage bag is fixedly installed in the embedded water tank, and the elastic water storage bag is adhesively connected to the inner wall of the embedded water tank on the side close to the rotation axis of the rotary drilling and ditching wheel. A plurality of air holes I are provided on the inner wall of the embedded water tank away from the rotation axis of the rotary drilling and ditching wheel. A pipe joint III is fixedly and connected to the elastic water storage bag, and the pipe joint III is inserted into the hose II and fixedly connected to the hose II.

[0008] Furthermore, the embedded pipeline includes flow channel I and flow channel II which can be connected to each other, flow channel I is arranged in the traction frame, and flow channel II is arranged in the rotary trenching wheel, and the connecting position of flow channel I and flow channel II is consistent with the rotation axis of the rotary trenching wheel.

[0009] Furthermore, the rotary trenching wheel is composed of two hollow covers spliced ​​in opposite directions, and the inner side wall of the hollow cover is integrally formed with a plurality of bosses, and the bosses on the two hollow covers correspond to each other one by one and are locked and fixed by fastener I.

[0010] Furthermore, a traveling wheel and a reversing wheel as well as a stepper motor I and a stepper motor II for respectively controlling the rotation of the traveling wheel and the reversing wheel are installed at the bottom of the drive control box.

[0011] Furthermore, a screw and a reduction motor I for driving the screw to rotate are installed inside the drive control box, and an internal threaded sleeve is fixedly installed on the crawling drive arm, and the internal threaded sleeve is connected to the screw through threaded transmission.

[0012] Furthermore, two transverse axes are arranged in the middle of the traction frame, the transverse axis close to the drive control box is rotatably connected to the bottom of the fixing seat, and the transverse axis away from the drive control box is connected to the top of the fixing seat through a shock absorbing spring.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The soil moisture control corn furrowing equipment of the present invention controls two crawling drive arms to slide back and forth alternately, and the positioning piles thereon extend vertically periodically, and controls the drive control box to move in a crawling manner among the rows of crops. During this process, the rotary digging furrowing wheel is controlled to rotate on the traction frame, and the rotary digging furrowing wheel and the rotary digging teeth on the side of the rotary digging furrowing wheel are used to dig the soil between the rows of crops. After the soil is shoveled and lifted up, it slides to the two sides of the rotary digging furrowing wheel to form a ridge structure between the rows of crops; because the drive control box and the rotary digging furrowing wheel are small in size and narrow in overall width, they can be smoothly It enters between rows of crops and digs a single ridge, eliminating the need to span across the upper sides of multiple ridges. Compared with traditional ditching equipment, it can be effectively used on surface terrain where crops are already growing, is not restricted by the crop growth cycle, and can deal with the problem of ridges gradually becoming flat after crop planting caused by wind erosion and water erosion. It can restore the ability of ridges in crop-planting areas to regulate moisture. In response to sudden droughts, it can open grooves on the surface where ridges have not been dug in advance for water irrigation, improve soil permeability, and promote the absorption of water and nutrients by crop roots.

[0015] 2. The soil moisture control corn furrowing equipment of the example of the present invention uses two crawling drive arms to slide alternately back and forth to replace the traditional rotating wheel as the power source for the crawling movement of the drive control box. It has a good fit with the ground. Since the length of the positioning pile is determined according to the height of the drive control box, it can be set longer so that the positioning pile can be inserted deeper into the ground to cope with irregular surface protrusions and the poor relative friction effect of moist surface soil on the rotating wheel. In the area where the ridges need to be dug, the root density of the crops is low, which will not affect the normal growth of the crops.

[0016] 3. In the soil moisture control corn furrowing equipment of the example of the present invention, water is filled into the rotary furrowing wheel, and the water enters the embedded water tank along the pipe joint I, hose I, pipe joint II, hose II, flow channel I and flow channel II; since the contact area between the drive control box and the rotary furrowing wheel and the surface soil is greatly different, after water is filled into the rotary furrowing wheel, the squeezing force of the bottom of the rotary furrowing wheel on the surface soil is increased, and it can be used to deal with relatively hard surface soil conditions.

[0017] 4. In the soil moisture regulating corn furrowing equipment of the example of the present invention, during the horizontal reciprocating sliding of the crawling drive arm, the strip protrusion at the bottom of the crawling drive arm is inserted into the sliding mouth at the bottom of the drive control box, so as to scrape the soil attached to the inner wall of the sliding mouth, avoid the soil adhering to the bottom of the drive control box, reduce the friction resistance of the drive control box when crawling between rows of crops, avoid this part of the soil from causing scraping damage to the crop root system, and ensure the smooth crawling of the equipment for a long time.

[0018] 5. The soil moisture control corn furrowing equipment of the example of the present invention utilizes the elastic deformation properties of the elastic water storage bag itself so that the water inside the embedded water tank always has a tendency to flow back into the main water tank, so as to accurately control the overall weight of the rotary digging and furrowing wheel, thereby preventing the rotary digging and furrowing wheel from exerting excessive squeezing pressure on the soil in the depressed area of ​​the surface, ensuring that the depth of the furrow dug by the rotary digging and furrowing wheel remains constant and the bottom of the furrow is smooth, thereby increasing the stability of soil moisture control.

[0027] Embodiment 1: like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the present embodiment provides a soil moisture regulation corn furrowing equipment, including a drive control box 11, a slope 112 is arranged on the lower side of the front end of the drive control box 11 to avoid shoveling the soil on the surface and increase the smoothness of the movement of the drive control box 11 on the surface, and concave surfaces 111 are arranged on the left and right sides of the drive control box 11 respectively, and the bottom width of the drive control box 11 is narrowed to reduce the scratching of the crop roots during the movement of the equipment, and a rotary digging furrowing wheel 31 is arranged at the rear end of the drive control box 11, and a plurality of rotary digging teeth 32 are arranged on the peripheral side of the rotary digging furrowing wheel 31; two creeping drive arms 12 are slidably installed at the bottom of the drive control box 11, each of which is provided with a plurality of rotary digging teeth 32; two creeping drive arms 12 are slidably installed at the bottom of the drive control box 11, each of which is provided with a plurality of rotary digging teeth 32; Two positioning piles 13 that can be inserted into the ground are vertically slidably installed on the crawling drive arms 12, and two slot arms 16 are fixedly installed on the upper bottom side of the drive control box 11. The cross arms 15 on the tops of the two crawling drive arms 12 are respectively engaged and slidably connected with the sliding grooves on the two slot arms 16, thereby increasing the sliding stability of the crawling drive arms 12; the drive control box 11 is connected to the rotary drilling and ditching wheel 31 through the fixed seat 25 and the traction frame 21; two end covers 22 are provided on the traction frame 21, and a rotating shaft is fixedly installed on the inner middle part of the end cover 22, and the rotating shafts on the two end covers 22 are respectively engaged and rotatably connected with the two sides of the rotary drilling and ditching wheel 31.

[0028] Among them, a plurality of probes 113 are arranged on the side of the drive control box 11. The probes 113 use wireless monitoring cameras that can be purchased on the market. The plurality of probes 113 are used to measure the distance between the side of the drive control box 11 and the crops, and to grasp the movement status of the drive control box 11 and the rotary trenching wheel 31 between the rows of crops.

[0029] like Figure 1 As shown, the drive control box 11 and the rotary trenching wheel 31 are respectively installed with a main water tank 41 and an embedded water tank 46. The main water tank 41 has a built-in water pump, and the water pump uses a bidirectional centrifugal water pump or a micro bidirectional gear pump. The main water tank 41 is connected to the embedded water tank 46 through a pipe joint Ⅰ42, a hose Ⅰ43, a pipe joint Ⅱ44, a hose Ⅱ45 and an embedded pipeline. The embedded water tank 46 is detachably fixedly connected to a hollow cover on one side through multiple fasteners Ⅱ35.

[0030] like Figure 6 As shown, the embedded pipeline includes a flow channel I 24 and a flow channel II 34 that can communicate with each other. The flow channel I 24 is arranged in the traction frame 21, and the flow channel II 34 is arranged in the rotary digging and ditching wheel 31. The communication position of the flow channel I 24 and the flow channel II 34 is consistent with the rotation axis of the rotary digging and ditching wheel 31, so that when the rotary digging and ditching wheel 31 rotates in the traction frame (21), the flow channel I 24 and the flow channel II 34 can remain in a state of communication with each other.

[0031] like Figure 5 , Figure 6 and Figure 8As shown, a sealing cover 411 is detachably fixedly installed on the top of the main water tank 41. The sealing cover 411 is removed and water is injected into the main water tank 41. The pipe joint Ⅰ42 is arranged at the lower end of the side of the main water tank 41. The pipe joint Ⅰ42 passes through the drive control box 11 and is connected to the hose Ⅰ43. The other end of the hose Ⅰ43 is connected to the pipe joint Ⅱ44. The pipe joint Ⅱ44 is fixedly installed on the traction frame 21 and is connected to the flow channel Ⅰ24. The flow channel Ⅱ34 is connected to the embedded water tank 46 through the hose Ⅱ45.

[0032] The specific details of the soil moisture regulation corn furrowing equipment using this application are as follows: 1. Preparation before use; According to the planting intervals of crops, a drive control box 11 and a rotary digging ditching wheel 31 of appropriate sizes are selected, and the drive control box 11 and the rotary digging ditching wheel 31 are placed together between the rows of crops, and the drive control box 11 is located in front of the rotary digging ditching wheel 31.

[0033] Second, while the driving control box 11 is moving between the rows of crops, the rotary digging and ditching wheels 31 are used to dig the ridge furrows; The two crawling drive arms 12 are controlled to slide back and forth alternately, and the positioning piles 13 thereon are periodically extended vertically, and the drive control box 11 is controlled to move in a crawling manner among the rows of crops. During this process, the rotary digging and ditching wheel 31 is controlled to rotate on the traction frame 21, and the rotary digging and ditching wheel 31 and the rotary digging teeth 32 on the side of the rotary digging and ditching wheel 31 are used to dig the soil between the rows of crops. After the soil is shoveled and lifted up, it slides to the two sides of the rotary digging and ditching wheel 31, forming a ridge structure between the rows of crops; During the crawling process of the equipment, the two crawling drive arms 12 slide at the front and rear ends of the drive control box 11 respectively, and periodically slide to switch their position states; the crawling drive arm 12 at the front end of the drive control box 11, the positioning pile 13 on the crawling drive arm 12 is in an upwardly retracted state, and when the crawling drive arm 12 begins to slide backward, the positioning pile 13 extends downward, and under the action of the equipment's own gravity, the lower end of the positioning pile 13 is inserted into the soil, providing a traction point between the drive control box 11 and the ground; when the crawling drive arm 12 slides to the rear end of the drive control box 11, the positioning pile 13 retracts upward and remains in a retracted state until the crawling drive arm 12 slides forward again and resets to its initial position; as the two crawling drive arms 12 slide back and forth alternately, the drive control box 11 is able to continuously crawl and move between rows of crops along the extension direction of the ridge to be excavated.

[0034] 3. Fine-tune the weight of the rotary trenching wheel 31 to adapt to the undulating surface soil and adjust the depth of the excavated trench; Start the water pump in the main water tank 41 and fill water into the rotary trenching wheel 31. The water flows into the embedded water tank 46 along the pipe joint Ⅰ42, the hose Ⅰ43, the pipe joint Ⅱ44, the hose Ⅱ45, the flow channel Ⅰ24 and the flow channel Ⅱ34. Since the contact area between the drive control box 11 and the rotary trenching wheel 31 and the surface soil is greatly different, after water is filled into the rotary trenching wheel 31, the squeezing force of the bottom of the rotary trenching wheel 31 on the surface soil is increased, which can be used to deal with relatively hard surface soil conditions.

[0035] In the above step one, since the drive control box 11 and the rotary trenching wheel 31 are small in size and narrow in overall width, they can smoothly enter between rows of crops and carry out excavation operations on a single ditch, so there is no need to straddle the upper side of multiple ditches. Compared with traditional trenching equipment, it can be effectively used on surface terrain where crops are already growing, is not restricted by the crop growth cycle, and can deal with the problem that ridges gradually become flat after crop planting caused by wind erosion and water erosion, restore the ability of ridges in crop planting areas to regulate moisture, and in response to sudden droughts, dig grooves on the surface where ridges have not been dug in advance for water irrigation, improve soil permeability, and promote the absorption of moisture and nutrients by crop roots.

[0036] In the above step 2, two crawling drive arms 12 are used to slide back and forth alternately, replacing the traditional rotating wheel, as the power source for the crawling movement of the drive control box 11, and the degree of fit with the ground is good. Since the length of the positioning pile 13 is determined according to the height of the drive control box 11, it can be set longer, so that the positioning pile 13 can be inserted into a deeper position on the ground to cope with the situation where the relative friction effect of irregular surface protrusions and moist surface soil on the rotating wheel is poor. In the area where the ridges need to be dug, the root density of the crops is low, which will not affect the normal growth of the crops.

[0037] In the present application, the control method for the horizontal movement of the crawling drive arm 12 and the vertical movement of the positioning pile 13 is as follows: A screw rod 19 and a reduction motor Ⅰ18 for driving the screw rod 19 to rotate are installed inside the drive control box 11, and an internal threaded sleeve 17 is fixedly installed on the crawling drive arm 12, and the internal threaded sleeve 17 is connected to the screw rod 19 through a threaded transmission; a linear electric cylinder 14 for driving the positioning pile 13 to move vertically is installed on the top of the crawling drive arm 12.

[0038] The reduction motor I18 and the linear electric cylinder 14 are started synchronously to control the periodic vertical movement of the positioning pile 13. At the same time, the control screw 19 is rotated about its own axis, and the threaded transmission between the screw 19 and the internal threaded sleeve 17 is utilized to drive the crawling drive arm 12 to slide horizontally back and forth at the bottom position of the drive control box 11.

[0039] In the present application, the rotation control method of the rotary trenching wheel 31 is as follows: The rotating shaft corresponding to the end cover 22 on one side passes through the rotary digging ditching wheel 31 and extends toward the inner direction of the rotary digging ditching wheel 31. A limit plate 23 is fixedly installed on the rotating shaft. The end of the limit plate 23 abuts against the inner wall of the rotary digging ditching wheel 31. A reduction motor II 33 is installed on the middle side of the end of the limit plate 23. The output shaft of the reduction motor II 33 is fixedly connected to the inner middle part of the rotary digging ditching wheel 31 through a flange assembly. The output shaft of the reduction motor II 33 and the rotation center of the rotary digging ditching wheel 31 are on the same virtual axis.

[0040] In order to facilitate cleaning and maintenance of the internal structure of the rotary trenching wheel 31, Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the rotary trenching wheel 31 is composed of two hollow covers spliced ​​in opposite directions, and the inner side wall of the hollow cover is integrally formed with a plurality of bosses 311. The bosses 311 on the two hollow covers correspond to each other one by one and are locked and fixed by fasteners Ⅰ312. The plurality of fasteners Ⅰ312 are removed to disassemble the two hollow covers, and the internal structure of the rotary trenching wheel 31 is cleaned and maintained.

[0041] In this embodiment, an air vent II is provided on the outer side of the embedded water tank 46, and a PTFE polytetrafluoroethylene film is installed on the air vent II to achieve ventilation while blocking water, so that the water in the main water tank 41 can smoothly enter the embedded water tank 46, and the air in the embedded water tank 46 can be smoothly discharged between the embedded water tank 46 and the inner wall of the rotary trenching wheel 31.

[0042] Embodiment 2: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 1 , Fig. 9 and Fig.10 As shown, in this embodiment, a strip protrusion is integrally formed on the middle side of the bottom of the crawling drive arm 12, and the positioning pile 13 passes through the strip protrusion and is slidably connected with the strip protrusion; a sliding opening is provided at the bottom of the drive control box 11, and the crawling drive arm 12 always covers and seals the upper side of the sliding opening to prevent soil from leaking into the drive control box 11, and the strip protrusion is slidably connected with the sliding opening, and the bottom surface of the strip protrusion and the bottom surface of the drive control box 11 are in the same virtual plane.

[0043] During the horizontal reciprocating sliding of the crawling drive arm 12, since the strip protrusion at the bottom of the crawling drive arm 12 is inserted into the sliding hole at the bottom of the drive control box 11, the soil attached to the inner wall of the sliding hole can be scraped to prevent the soil from adhering to the bottom of the drive control box 11, thereby reducing the friction resistance of the drive control box 11 when crawling between rows of crops, avoiding this part of the soil from causing scraping damage to the crop roots, and ensuring the smoothness of the equipment's long-term crawling.

[0044] Embodiment three: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 1 and Fig.10 As shown, in this embodiment, elastic sealing strips 121 are fixedly installed on the front and rear sides of the bottom of the crawling drive arm 12, one end of the elastic sealing strip 121 is connected to the end of the strip-shaped protrusion at the bottom of the crawling drive arm 12, and the other end of the elastic sealing strip 121 is connected to the inner wall of the bottom sliding opening of the drive control box 11, and the bottom surface of the elastic sealing strip 121 and the bottom surface of the drive control box 11 are in the same virtual plane.

[0045] An elastic sealing strip 121 is used to seal the area between the end of the strip protrusion and the end of the bottom slide of the drive control box 11, completely isolating the path for soil to enter the bottom slide of the drive control box 11, thereby reducing the interference of soil conditions on the continuity of equipment operation; the elastic sealing strips 121 on both sides of the bottom of the crawling drive arm 12 are respectively in a stretched state and a contracted state. As the crawling drive arm 12 slides horizontally back and forth, the stretched state and the contracted state of the elastic sealing strip 121 change periodically.

[0046] Embodiment 4: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 2 As shown, in this embodiment, a traveling wheel 122 and the driving control box 11 as well as a stepper motor I and a stepper motor II for respectively controlling the rotation of the traveling wheel 122 and the reversing wheel 123 are installed at the bottom of the driving control box 11. The extension direction of the rotation axis of the traveling wheel 122 is perpendicular to the traveling direction of the driving control box 11, and the extension direction of the rotation axis of the reversing wheel 123 is consistent with the traveling direction of the driving control box 11.

[0047] Start stepper motor I to assist the drive control box 11 to move forward; start stepper motor II to assist the drive control box 11 to move laterally and fine-tune the travel direction of the drive control box 11 to cope with the excavation of ridges with a relatively tortuous extension direction to avoid damage to crops and crop roots.

[0048] Embodiment five: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 7As shown, in this embodiment, an elastic water storage bag 47 is fixedly installed in the embedded water tank 46, and the elastic water storage bag 47 is adhesively connected to the inner wall of the embedded water tank 46 on the side close to the rotation axis of the rotary digging ditching wheel 31. A plurality of air holes I are provided on the inner wall of the embedded water tank 46 away from the rotation axis of the rotary digging ditching wheel 31, so that the elastic water storage bag 47 can expand or contract smoothly, and a pipe joint III48 is fixed and connected to the elastic water storage bag 47, and the pipe joint III48 is inserted into the hose II45 and fixedly connected to the hose II45.

[0049] By utilizing the elastic deformation properties of the elastic water storage bag 47 itself, the water inside the embedded water tank 46 always has a tendency to flow back into the main water tank 41, so that the overall weight of the rotary ditching wheel 31 can be accurately controlled, avoiding the rotary ditching wheel 31 from exerting excessive squeezing pressure on the soil in the depressed area of ​​the surface, ensuring that the depth of the ditch excavated by the rotary ditching wheel 31 remains constant, the bottom of the ditch is smooth, and the stability of soil moisture regulation is increased.

[0050] During the process of the water inside the embedded water tank 46 flowing back into the main water tank 41, the water inside the embedded water tank 46 flows through the pipe joint III 48, the hose II 45, the flow channel II 34, the flow channel I 24, the pipe joint II 44, the hose I 43 and the pipe joint I 42 in sequence, and flows back to the main water tank 41 for storage, thereby reducing the overall weight of the rotary trenching wheel 31.

[0051] Embodiment six: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, two transverse axes 211 are provided in the middle part of the traction frame 21, the transverse axis 211 close to the drive control box 11 is rotatably connected to the bottom of the fixed seat 25, and the transverse axis 211 away from the drive control box 11 is connected to the top of the fixed seat 25 through a shock-absorbing spring 26; swivel rings 261 are fixedly installed at both ends of the shock-absorbing spring 26, and the two swivel rings 261 are rotatably connected to the transverse axis 211 and the top of the fixed seat 25 respectively.

[0052] The drive control box 11 and the rotary digging ditching wheel 31 are connected by using the traction frame 21. Since the horizontal axis 211 can rotate relative to the fixed seat 25, it has high flexibility and can cope with the situation of soil with many irregular protrusions on the surface. Under the action of the shock-absorbing spring 26, the rotary digging ditching wheel 31 always has a tendency to move downward, maintaining a close connection between the rotary digging teeth 32 on the side of the rotary digging ditching wheel 31 and the surface soil. During this process, the shock-absorbing spring 26 applies a pushing force to the horizontal axis 211 away from the side of the drive control box 11, so that the traction frame 21 and the rotary digging ditching wheel 31 rotate together with the axis of the horizontal axis 211 on the side of the drive control box 11.
