Description

Technical Field

[0001] The invention relates to the field of agricultural machinery and equipment, in particular to integrated wheat precision sowing and loosening equipment. Background Art

[0002] Good wheat sowing management can improve soil utilization efficiency. Good soil loosening management can make the soil looser, which is beneficial to the respiration and nutrient absorption of wheat roots, promotes root development, enhances the plant's resistance to diseases and pests, and also helps crops absorb water and nutrients, thereby increasing yield and improving quality.

[0003] The existing application number is CN202210195278.3, and the patent document discloses a scheme of combining rotary tillage, sowing, fertilizing and pressing components to deal with details of various aspects of the wheat sowing process, among which, in particular, a wheat seed diversion component is used, so that the wheat seeds rebound multiple times during the flow in the diversion component and then fall to the ground, so that the wheat seeds can flow smoothly and disperse with each other, and the purpose of uniform sowing is achieved. Specifically: the wheat seeds enter the wheat seed guide tube from the wheat seed box, and then enter the second guide tube from the wheat seed guide tube, and then enter the uniform sowing chamber from the second guide tube. The wheat seeds are diverted by the diversion parts under each second guide tube outlet respectively, and the diverted wheat seeds are collided and rebounded by the first uniform sowing plate and the second uniform sowing plate in turn, and finally fall evenly to the ground;

[0004] However, when using the technical solution in the above-mentioned patent document, since the sowing component is arranged between the rotary tillage component and the suppression component, the loose soil processed by the rotary tillage component will affect the natural falling of the wheat seeds, causing the originally scattered wheat seeds to be affected by the uneven ground and re-gathered in one place, affecting the accuracy of the sowing position of the wheat seeds, resulting in a reduction in the uniform sowing effect of the wheat seeds; in addition, when facing the situation of wheat planting in sandy loam, tilling the sandy loam will destroy the soil layer structure, causing the organic matter and beneficial microorganisms in the deeper layer of the soil to be turned to the upper layer of the soil. Under the action of soil sandification, it will cause the loss of organic matter, affecting the soil fertility and crop growth. Therefore, the present application provides an integrated equipment for wheat precision sowing and loosening soil. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The integrated equipment for precision sowing and loosening the soil of wheat in the example of the present invention starts the air compressor, and injects compressed air into the horizontal cylinder through the air injection pipe. The compressed air in the horizontal cylinder flows through the L-shaped air pipe, and is finally ejected from the air jet at the end of the L-shaped air pipe, and the compressed air is released in the soil layer below the surface. The airflow flows along the gaps between the soil particles, so that the gaps between the soil particles are increased, and the soil containing organic matter in the deep layer is loosened. Since the compressed air is released in the soil layer below the surface, the soil is loosened only at the soil depth layer where the wheat root system grows, and no damage is caused to the soil above the surface.

[0021] 2. The integrated equipment for precision sowing and loosening the soil of wheat in the example of the present invention starts the electromagnetic pulse valve and intermittently injects compressed air into the horizontal cylinder. Part of the compressed air flowing through the vertical section inside the L-shaped air pipe enters the embedded tube along the conical bucket and the serpentine guide tube, and blows the wheat seeds moved into the embedded tube, applying the wheat seeds to the soil at a higher speed, so that the wheat seeds can be stably embedded in the specified position of the soil, accurately controlling the sowing position of the wheat seeds, avoiding blockage of the wheat seeds, and achieving good continuous sowing effect.

[0022] 3. The integrated equipment for wheat precision sowing and loosening the soil in an example of the present invention utilizes the compressed air flowing through the vertical section inside the L-shaped air pipe to apply a vertical downward pressing force to the conical bucket, and utilizes an electromagnetic pulse valve to intermittently inject compressed air into the horizontal cylinder. Under the action of the tension spring, the sealed air guide, the conical bucket and the embedded tube are vertically reciprocated and lifted between the L-shaped air pipe and the wheat seed conduit. The wheat seeds flowing through the embedded tube are moved by the wheat seed prying tool to prevent multiple wheat seeds from clumping together and adhering to each other, so that the wheat seeds can be evenly dispersed and embedded in the soil.

[0023] 4. In the integrated equipment for precision sowing and loosening the soil of wheat in the example of the present invention, the anti-clogging is arranged at the end of the conical end head, a main airway is arranged inside the anti-clogging, and a plurality of oblique exhaust channels connected to the main airway are arranged at equal angles at one end of the anti-clogging toward the outside of the conical end head. Since the oblique exhaust channels are inclined and have a certain angle with respect to the horizontal section of the L-shaped air pipe, the multiple oblique exhaust channels can be used to make the airflow sprayed into the soil more dispersed, thereby improving the loosening effect of deep soil containing organic matter.

[0024] 5. The integrated wheat precision sowing and loosening soil equipment of the example of the present invention, when facing relatively hard soil blocks or a large amount of loose soil, as the power equipment moves, the soil exerts a squeezing force on the end of the sealing cover. Due to the uncertainty of soil conditions in various places on the surface, the squeezing force exerted by the soil on the end of the sealing cover changes dynamically. When the squeezing force is greater than the driving force of the compressed air on the sealing end, the spring is compressed and contracts; the synchronous folding seat moves deep into the anti-blocking interior, and the inner edge of the sealing end is tightly attached to the end of the oblique exhaust channel, and the end opening of the oblique exhaust channel is automatically closed to prevent the oblique exhaust channel from being blocked by a large amount of loose soil, and the equipment has a good continuous use effect.

[0047] Embodiment 1:

[0048] like Figure 1 , Figure 2 and Figure 6 As shown, the present embodiment provides an integrated equipment for wheat precision sowing and loosening soil, including a vehicle body connecting frame 1, wherein the vehicle body connecting frame 1 includes a base 11 which is detachably fixedly mounted on a power device, a transverse cylinder 12 is arranged on the lower side of the base 11, an air injection pipe 13 is fixedly and connectedly arranged on the side of the transverse cylinder 12, the other end of the air injection pipe 13 is connected to an air compressor through a polytetrafluoroethylene pressure hose, and an electromagnetic pulse valve is arranged on the polytetrafluoroethylene pressure hose so as to intermittently inject compressed air into the transverse cylinder 12.

[0049] The power equipment may be wheeled tractors and crawler tractors of the John Deere agricultural machinery tractor, Dongfanghong tractor and Zoomlion tractor brands. The specific equipment models may be adjusted according to the actual soil conditions.

[0050] like Figure 1 and Figure 7 As shown, the plow body 2 includes an L-shaped air pipe 21 and a plow blade 22 fixedly installed on the upper side of the L-shaped air pipe 21. The L-shaped air pipe 21 is arranged at the bottom of the horizontal cylinder 12 and is connected to the horizontal cylinder 12. The L-shaped air pipe 21 has an L-shaped structure, which divides the L-shaped air pipe 21 into two parts: a vertical section and a horizontal section.

[0051] like Figure 1 As shown, the lower end of the plow blade 22 extends toward the outer side of the horizontal section end of the L-shaped air pipe 21, blocking the air jet outlet at the end of the L-shaped air pipe 21, preventing soil particles from entering the L-shaped air pipe 21 as the power equipment moves, and ensuring that the compressed gas flowing through the L-shaped air pipe 21 can be continuously and stably ejected into the soil layer below the surface.

[0052] like Figure 1 , Figure 3 , Figure 7 , Fig. 9 and Fig.14As shown, a precision sowing component 4 is provided on the side of the vertical section of the L-shaped air pipe 21, and the precision sowing component 4 includes a wheat seed conduit 41 and an embedded tube 46. The embedded tube 46 is slidably installed in the wheat seed conduit 41, and the outer side surface of the embedded tube 46 is in contact with the inner side surface of the wheat seed conduit 41. A plurality of wheat seed ridges 461 for preventing a plurality of wheat seeds from clumping and adhering to each other are fixedly installed on the inner side of the embedded tube 46. The plurality of wheat seed ridges 461 are respectively located on both sides of the inner part of the embedded tube 46. The wheat seed conduit 41 is fixedly installed on the U-shaped arm 24 on the side of the L-shaped air pipe 21, and the other end of the wheat seed conduit 41 is connected to the wheat seed storage box through a hose.

[0053] like Figure 1 , Figure 7 , Figure 8 , Fig. 9 and Fig.13 As shown, the side of the embedded tube 46 is fixed and connected with a sealing air guide 42, which is slidably installed between the L-shaped air pipe 21 and the wheat seed conduit 41. The sealing air guide 42 is plugged and slidably connected with the slide groove 411 on the side of the wheat seed conduit 41, and covers the sides of the L-shaped air pipe 21 and the wheat seed conduit 41; a tension spring 421 is fixedly installed between the sealing air guide 42 and the wheat seed conduit 41 for pulling the sealing air guide 42 to automatically rise.

[0054] like Fig. 9 , Fig.13 and Fig.14 As shown, the sealed air guide 42 is fixed and connected to the side thereof with a serpentine duct 44 for guiding the high-pressure airflow flowing through the L-shaped air pipe 21 to the inner side and lower side of the embedded tube 46. The specific structure is shown in 9, so as to implement the wheat seed spraying operation; the other end of the serpentine duct 44 extends toward the upper side of the inside of the L-shaped air pipe 21, and a sealing edge 211 is fixedly installed on the side of the L-shaped air pipe 21. The outer side surface of the serpentine duct 44 is tightly fitted against the inner side surface of the sealing edge 211 to reduce wear; the top of the serpentine duct 44 is integrally formed with a conical bucket 45, and the opening direction of the conical bucket 45 is opposite to the flow direction of the airflow inside the L-shaped air pipe 21.

[0055] The steps of using the wheat precision sowing and loosening integrated equipment of the present application to carry out wheat loosening and sowing operations are as follows:

[0056] Step 1: Install the base 11 on the power equipment, and as the power equipment moves, use the plow 22 to loosen the soil layer on the surface, forming strip-shaped pits on the surface to provide space for the L-shaped air pipe 21 and the wheat seed conduit 41 to be inserted;

[0057] Step 2: Start the air compressor and inject compressed air into the horizontal cylinder 12 through the air injection pipe 13. The compressed air in the horizontal cylinder 12 flows through the L-shaped air pipe 21 and finally ejects from the air jet at the end of the L-shaped air pipe 21, releasing the compressed air in the soil layer below the surface. The airflow flows along the gaps between the soil particles, increasing the gaps between the soil particles. On the basis of reducing the damage to the top structure of the soil, the soil containing organic matter in the deep layer is loosened to avoid turning this part of the soil to the surface.

[0058] Step 3: Add wheat seeds into the wheat seed conduit 41, so that the wheat seeds move downward along the wheat seed conduit 41 into the embedded tube 46;

[0059] Step 4: Start the electromagnetic pulse valve and intermittently inject compressed air into the horizontal cylinder 12. Part of the compressed air flowing through the vertical section inside the L-shaped air pipe 21 enters the embedded tube 46 along the conical bucket 45 and the serpentine guide tube 44, and blows the wheat seeds moved into the embedded tube 46, applying the wheat seeds to the soil at a higher speed, so that the wheat seeds can be stably embedded in the specified position of the soil, accurately controlling the sowing position of the wheat seeds, avoiding wheat seed blockage, and achieving good continuous sowing effect.

[0060] In the above step one, the moving direction of the power equipment is defined as forward, and the plow blade 22, L-shaped air pipe 21 and wheat seed conduit 41 are arranged in sequence from front to back, and the surface soil plowing operation, the subsurface soil loosening operation and the wheat seed spraying operation are carried out in sequence; because the compressed air is released in the soil layer below the surface, the soil loosening operation is only carried out on the soil depth layer where the wheat root system grows, and no damage is caused to the soil above the surface.

[0061] In the above step three, the wheat seeds can be put into the wheat seed conduit 41 by the vibration generated by the running of the power equipment, so that the wheat seeds in the wheat seed storage box enter the wheat seed conduit 41 along the hose. A screw conveyor that can be purchased on the market can also be added to the wheat seed storage box to continuously supply the wheat seeds into the hose for continuous spraying of the wheat seeds.

[0062] In the above step four, the compressed air flowing through the vertical section inside the L-shaped air pipe 21 is used to apply a vertical downward pressing force to the conical bucket 45, and the electromagnetic pulse valve is used to intermittently inject compressed air into the horizontal cylinder 12. Under the action of the tension spring 421, the sealed air guide 42, the conical bucket 45 and the embedded tube 46 are vertically reciprocated and lifted between the L-shaped air pipe 21 and the wheat seed conduit 41. The wheat seeds flowing through the embedded tube 46 are moved by the wheat seed ridges 461 to prevent multiple wheat seeds from clumping together and adhering to each other, so that the wheat seeds can be evenly dispersed and embedded in the soil.

[0063] In order to facilitate the adjustment of the inclination angle of the coulter 22, as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the L-shaped air pipe 21 is rotatably installed at the bottom of the horizontal cylinder 12, so that the top rotating sleeve 23 of the L-shaped air pipe 21 is nested on the outside of the bottom conducting cylinder 14 of the horizontal cylinder 12, and a driving column 241 is set on the U-shaped arm 24, and the driving columns 241 corresponding to multiple plow bodies 2 are connected together through a synchronization arm 16.

[0064] Since the relative positions of the multiple L-shaped air pipes 21 and the conducting tube 14 at the bottom of the horizontal tube 12 remain constant, the synchronization arm 16 can always remain flush with the side surface of the horizontal tube 12; the synchronization arm 16 is manually moved, and the relative angles of the conducting tube 14 and the rotating sleeve 23 are locked using fasteners, driving the multiple L-shaped air pipes 21 to rotate synchronously relative to their respective corresponding conducting tubes 14, thereby adjusting the angle between the plow blade 22 and the travel direction of the power equipment, as well as the position of the jet port at the end of the L-shaped air pipe 21.

[0065] When the plow blade 22 is in the same direction as the travel direction of the power equipment, the plow blade 22 loosens the surface soil, and the strip-shaped depression left on the surface has a lower degree of damage to the surface than the plowing components in the background technology, and will not turn the organic matter and beneficial microorganisms in the deeper layer of the soil to the upper layer of the soil, thereby avoiding a large loss of organic matter due to the influence of soil sandification and reducing the damage to the soil layer structure.

[0066] When the plow blade 22 forms an angle with the traveling direction of the power equipment, the side position of the plow blade 22 is utilized to turn the loosened soil to one side for subsequent fertilization operations.

[0067] In order to increase the sliding stability of the sealing air guide 42 between the L-shaped air pipe 21 and the wheat seed conduit 41, as shown in FIG. Fig.13 As shown, a plurality of slip rings 43 are fixedly installed on both sides of the sealing air guide 42, and the plurality of slip rings 43 on both sides are respectively sleeved and slidably installed on the outside of the L-shaped air pipe 21 and the wheat seed conduit 41; the tension spring 421 is installed on the slip ring 43 located at the upper end of the outer side of the wheat seed conduit 41, and the top of the tension spring 421 is fixedly connected to the wheat seed conduit 41 through a sleeve structure; the sealing air guide 42 can stably slide between the L-shaped air pipe 21 and the wheat seed conduit 41 by means of the sleeve-sliding connection of the plurality of slip rings 43 with the L-shaped air pipe 21 and the wheat seed conduit 41.

[0068] In order to facilitate the adjustment of the pitch angle of the plow blade 22, Figure 1 As shown, the transverse cylinder 12 is rotatably mounted on the bottom of the base 11 , and shafts are fixedly mounted on both ends of the transverse cylinder 12 , so that the shafts are plug-connected and rotatably connected with the support arms at the bottom of the base 11 .

[0069] In this embodiment, the method for controlling the rotation of the horizontal cylinder 12 at the bottom of the base 11 is as follows: a rotating driver (not shown in the figure) for driving the shaft rod at the end of the horizontal cylinder 12 to rotate is installed on the base 11, and the rotating driver is started to drive the horizontal cylinder 12 to rotate at the bottom of the base 11, adjust the pitch angle of the plow 22, loosen the soil with different depth requirements, and change the sowing depth at the same time.

[0070] Embodiment 2:

[0071] 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 3 and Fig.10 As shown, in this embodiment, an air jet is provided at the end of the horizontal section of the L-shaped air pipe 21, and a multi-directional air guide terminal 3 is installed at the air jet. The multi-directional air guide terminal 3 includes a conical terminal 31 and an anti-blocking 32. The conical terminal 31 is detachably fixedly installed at the lower end of the L-shaped air pipe 21, and the anti-blocking 32 is arranged at the end of the conical terminal 31. A main airway is arranged inside the anti-blocking 32. A plurality of oblique exhaust channels 321 connected to the main airway are arranged at equal angles at one end of the anti-blocking 32 facing the outer side of the conical terminal 31. Since the oblique exhaust channels 321 are inclined and have a certain angle relative to the horizontal section of the L-shaped air pipe 21, the multiple oblique exhaust channels 321 are used to make the airflow sprayed into the soil more dispersed, thereby improving the loosening effect of deep soil containing organic matter.

[0072] Among them, the middle part of the anti-blocking 32 is provided with an inwardly recessed bulge, and the bulge in the middle of the inner side of the anti-blocking 32 forms two trumpet mouths with opposite opening directions at both ends of the main airway, which increases the air flow rate flowing through the anti-blocking 32 and restricts the soil from entering the L-shaped air pipe 21.

[0073] Embodiment three:

[0074] 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 6 As shown, in this embodiment, a first telescopic driver 15 is installed between the transverse cylinder 12 and the synchronous arm 16, and the fixed end and the movable end of the first telescopic driver 15 are rotatably mounted on a ring seat 151 on the outside of the transverse cylinder 12 and a rotating shaft 152 on the top of the synchronous arm 16 respectively.

[0075] Start the first telescopic drive 15, control the movement of the synchronous arm 16, drive the multiple L-shaped air pipes 21 to rotate synchronously relative to their corresponding guide tubes 14, adjust the angle between the plow 22 and the travel direction of the power equipment, and the position of the air jet at the end of the L-shaped air pipe 21; in addition, by controlling the periodic swing of the plow 22, it is possible to apply an extrusion and pushing force in a direction horizontal and vertical to the travel direction to the agglomerated sandy loam, thereby crushing it.

[0076] Compared with the method of controlling the movement of the synchronization arm 16 in the first embodiment, the above scheme of the present embodiment can increase the convenience of movement control and operation response efficiency of the synchronization arm 16. Figure 4 , Figure 5 and Figure 7 As shown, the tilt angle of the plow blade 22, the jet range of the multi-directional air guide terminal 3 and the spraying position of the wheat seeds by the wheat seed conduit 41 are dynamically adjusted, and the operation flexibility is good.

[0077] Embodiment 4:

[0078] 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 3 As shown, in this embodiment, a cross arm 121 is fixedly installed on the shaft rod at the end of the cross cylinder 12, a sliding sleeve 122 is slidably installed on the cross arm 121, at least two second telescopic drivers 17 are installed on the base 11, and a hinged end 171 is fixedly installed on the movable end of the second telescopic driver 17, and the hinged end 171 is rotatably connected to the sliding sleeve 122.

[0079] The second telescopic driver 17 is started to control the movement of the hinged end 171, driving the sliding sleeve 122 to slide on the cross arm 121, so that the cross cylinder 12 and the cross arm 121 rotate together at the bottom of the base 11, as shown in FIG. Figure 1 As shown, the pitch angle of the coulter 22 is adjusted to loosen the soil at different depth requirements and change the sowing depth at the same time.

[0080] Compared with the method of controlling the rotation of the transverse cylinder 12 in the first embodiment, the above-mentioned scheme of this embodiment moves the force point acting on the transverse arm 121 away from the rotation center of the shaft rod at the end of the transverse cylinder 12, thereby being able to control the rotation of the transverse cylinder 12 more effortlessly, reducing the power requirements for the driving components and optimizing the manufacturing cost of the equipment.

[0081] Embodiment five:

[0082] 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: Fig.10 , Fig.11 and Fig.12 As shown, in this embodiment, a synchronous retracting seat 33 is slidably installed on the inner side of the end of the anti-blocking 32, and a plurality of blocking ends 36 on the synchronous retracting seat 33 are used to prevent soil from entering the oblique exhaust channel 321.

[0083] Specifically: a plurality of blocking ends 36 are rotatably mounted on one end of the synchronous folding seat 33, the blocking end 36 penetrates the oblique exhaust channel 321, and the inner side of the end of the blocking end 36 can block the end of the oblique exhaust channel 321; the other end of the synchronous folding seat 33 extends toward the outer side of the anti-blocking 32, and a sealing cover 34 is fixedly mounted on one end of the synchronous folding seat 33 located on the outer side of the anti-blocking 32, and a spring 35 is sleeved on the outer side of the synchronous folding seat 33, and the two ends of the spring 35 are respectively fixedly connected to the sealing cover 34 and the outer side of the end of the anti-blocking 32;

[0084] In the natural state, the spring 35 applies a traction force to the sealing cover 34, so that the blocking end 36 remains extended to the outside of the end of the oblique exhaust channel 321, so that the high-pressure airflow flowing through the anti-blocking 32 is ejected from the blocking end 36 and the annular channel at the end of the oblique exhaust channel 321; on the one hand, the ejected airflow can be more dispersed, thereby improving the loosening effect on the deep soil; on the other hand, the width of the air jet port is reduced, thereby limiting the entry of soil particles with larger particle sizes into the oblique exhaust channel 321.

[0085] When the above solution of this embodiment is used, when facing a relatively hard soil block or a large amount of loose soil, as the power equipment moves, the soil exerts a squeezing force on the end of the sealing cover 34. Due to the uncertainty of the soil conditions at various places on the surface, the squeezing force exerted by the soil on the end of the sealing cover 34 changes dynamically. When the squeezing force is greater than the driving force of the compressed air on the plugging end 36, the spring 35 is compressed and contracted;

[0086] During this process, the synchronous folding seat 33 moves deep into the anti-blocking 32, and the inner edge of the sealing end 36 is tightly attached to the end of the oblique exhaust channel 321, and the end opening of the oblique exhaust channel 321 is automatically closed to prevent a large amount of loose soil from clogging the oblique exhaust channel 321, and the equipment has a good continuous use effect.

[0087] In the present application, the telescopic drive uses a linear electric cylinder or a hydraulic cylinder that can be purchased on the market; the rotation drive uses a stepper motor or a servo motor that can be purchased on the market.

[0088] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.

[0089] Except for the technical features described in the specification, the remaining technical features are known technologies to those skilled in the art. In order to highlight the innovative features of the present invention, the remaining technical features will not be described here in detail.
