Description

Technical Field

[0001] The present invention relates to the technical field of land improvement, and more specifically, to a device for adjusting the soil pH value of farmland. Background Art

[0002] The acidity and alkalinity of soil, also known as "soil pH", is the general term for soil acidity and alkalinity. It is usually used to measure the strength of soil acid-base reaction. The influence of acidity and alkalinity on plants is multi-faceted, generally divided into the influence on the external environment and the influence on the plant itself. It is necessary to adjust the soil pH value to ensure the normal growth of plants. However, some methods of adjusting the soil pH value are to disperse the corresponding acid-base adjusting powder on the soil surface, which results in uneven mixing with the soil and slow penetration of the acid-base adjusting powder into the soil, causing some soil to not effectively absorb the drug. Therefore, it is necessary to provide a device for adjusting the soil pH value of farmland to solve the problems raised in the above background art. Summary of the Invention

[0003] To achieve the above object, the present invention provides the following technical solution: A device for adjusting the soil pH value of farmland, comprising:

[0004] A body, which bears the whole device and protects the device;

[0005] Drive wheels, which are arranged at the front of the body, and driven wheels opposite thereto are arranged at the rear of the body;

[0006] A tilling rotating shaft, which is connected to the body through a rotating arm;

[0007] A driving motor, which is fixed at the front of the body and provides the main power source for the device;

[0008] A leveling rotating shaft, which is arranged behind the tilling rotating shaft;

[0009] A feeding device, which is fixed inside the body and is located behind the leveling rotating shaft;

[0010] A mixing device, which is fixed inside the body and is arranged corresponding to the feeding device, and a spraying assembly is arranged behind the mixing device;

[0011] A transmission mechanism, which connects the tilling rotating shaft, the driving motor, the leveling rotating shaft and the feeding device;

[0012] A rotating motor, which is connected to the mixing device.

[0013] Further, preferably, the tilling rotating shaft is rotatably connected to the machine body through a rotating arm and is connected to the driving motor through a transmission mechanism. That is to say, driven by the rotating arm, the tilling rotating shaft rotates, thereby adjusting the contact depth between the tilling rotating shaft and the soil. Moreover, the rotating arm and the transmission mechanism do not affect each other. After the position of the tilling rotating shaft is adjusted by the rotating arm, the driving motor drives the tilling rotating shaft to rotate through the transmission mechanism 8 to perform the soil turning work.

[0014] Further, preferably, a plurality of wave-shaped steel bars are annularly distributed on the outer circle of the leveling rotating shaft. The wave-shaped steel bars on the leveling rotating shaft are located slightly below the land surface. Thus, driven by the transmission mechanism, the leveling rotating shaft drives the plurality of wave-shaped steel bars to rotate to crush the turned soil blocks and keep the land surface flat at the same time.

[0015] Further, preferably, the feeding device includes:

[0016] A loading frame fixed inside the machine body;

[0017] A storage bin arranged on the top of the loading frame;

[0018] A mixing and conveying bin arranged at the bottom of the storage bin and internally provided with a conveying rotating shaft;

[0019] A feeding pipe connected to the bottom outlet of the mixing and conveying bin;

[0020] A ditching group, which is linearly distributed with multiple groups from front to back, and the contact depth of each group with the soil decreases in turn;

[0021] Ditching components, which are linearly distributed with multiple ones to form the ditching group. That is to say, when the whole equipment moves forward, the leveling rotating shaft levels the land after soil turning, and then the ditching components in the ditching group perform the ditching work. Meanwhile, the acid-base regulating powder in the storage bin is conveyed to the mixing and conveying bin, and the transmission mechanism drives the conveying rotating shaft to rotate, and conveys the acid-base regulating powder to the ditch through the feeding pipe. Since the contact depth of each group of the ditching group with the soil changes in turn, that is, the acid-base regulating powder is conveyed to the soil from deep layer to surface layer in turn. Thus, when mixing in the mixing device, it can effectively ensure that the acid-base regulating powder is fully mixed with the soil, avoiding the phenomenon of uneven mixing caused by lack and failing to achieve the expected effect.

[0022] Further, preferably, all the ditching components in the ditching group are not arranged in coincidence. That is to say, the distribution of the ditching components in the next ditching group is set at intervals with reference to all the previous ditching groups. The setting of multiple ditching groups gradually subdivides the intervals between the ditching components. The multiple ditch channels with different depths enable the acid-base regulating powder to be distributed between the soil layers, so as to facilitate the full mixing of the soil and the acid-base regulating powder.

[0023] Furthermore, preferably, the ditching assembly includes:

[0024] A ditching knife, which is arc-shaped, is located below the bearing frame and penetrates into the soil;

[0025] A limiting sleeve, which is fixed on the convex side of the ditching knife and is connected to the material conveying pipe;

[0026] A connecting plate, which is a telescopic adjustable structure and connects the ditching knife and the bearing frame. Under the action of the connecting plate, the contact depth between the ditching knife and the soil in each ditching group can be actively adjusted. While the ditching knife is ditching the land, the material conveying pipe fixed on the limiting sleeve conveys the acid-base regulating powder into the ditch. Through multiple ditching assemblies, the acid-base regulating powder is conveyed to different positions and depths of the soil for preliminary distribution.

[0027] Furthermore, preferably, the mixing device includes:

[0028] Multiple mixing components are linearly distributed and correspond to the ditching groups, and the contact depth between the bottom of the mixing components and the soil increases in sequence;

[0029] A rotating shaft, which is fixedly connected to the rotating motor and connects multiple mixing components. Driven by the rotating motor, the rotating shaft drives the mixing components to perform reciprocating misaligned movements, fully mixing the soil and the acid-base regulating powder on the same horizontal plane. And through the sequential mixing of multiple mixing components, the soil is mixed from the surface layer to the deep layer in sequence to achieve the purpose of full mixing.

[0030] Furthermore, preferably, the mixing component includes:

[0031] A limiting frame, which is fixed inside the machine body;

[0032] Two moving parts are symmetrically distributed and are slidably arranged on both sides of the limiting frame;

[0033] Two rotating circular surfaces are symmetrically distributed and are rotatably arranged at the center of the limiting frame, and the middle part thereof is fixedly connected to the rotating shaft;

[0034] A moving panel, which is correspondingly arranged with the moving part and is fixed at the bottom of the moving part;

[0035] Multiple inclined surfaces are linearly distributed and are fixed at the bottom of the moving panel, and the inclined angles of the inclined surfaces on both sides of the moving panel are opposite. Driven by the rotating shaft, the rotating circular surface rotates, driving the two moving parts on both sides to slide in the opposite direction on the limiting frame, and at the same time driving the bottom moving panel to move. The acid-base regulating powder in the ditch is mixed with the soil on both sides through the inclined surfaces, and the inclined surfaces are inclined with respect to the moving panel, effectively reducing the resistance of the inclined surfaces to the soil during the movement.

[0036] Further, as a preference, tooth tracks are provided on both the upper and lower sides of the moving member, a limiting tooth is provided at one end of the tooth track, and the positions of the upper and lower limiting teeth are opposite.

[0037] Further, as a preference, tooth blocks are arc - distributed on the rotating circular surface, the tooth blocks are engaged with the tooth tracks, and the tooth blocks on both sides of the rotating circular surface are centrosymmetric about the connection center of the rotating circular surface. That is to say, the rotating circular surface mainly drives the moving member to move on the limiting frame body through the mutual engagement between the tooth blocks and the tooth tracks. Then, the tooth blocks are differently distributed on both sides of the rotating circular surface. That is, when the current - side tooth block is engaged with the lower tooth track, the rear - side tooth block is engaged with the upper tooth track, which drives the two - side moving members to move in opposite directions. And under the limitation of the limiting teeth, when the tooth blocks switch between the upper and lower two tooth tracks, effective limitation is carried out. It should be noted that to ensure the limiting effect of the limiting teeth, the rotating circular surface rotates clockwise.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] In the present invention, the soil is trenched at different depths and non - repeating positions by multiple groups of trenching components with different heights. While trenching from deep to shallow, the acid - base regulating powder is conveyed into the trenches, so that the acid - base regulating powder is distributed in different layers of the soil. Under the action of the mixing device, the soil layer is mixed from shallow to deep, so that the acid - base regulating powder in each layer of soil is fully mixed with the soil. And under the action of the tail spraying component, the mixed soil is wetted to promote the absorption of the acid - base regulating powder by the soil. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0047] Please refer to Figures 1 to 6 , in the embodiment of the present invention, a farmland soil pH adjustment device includes:

[0048] Body 1, carrying the whole device and protecting the device;

[0049] Drive wheel 2, arranged at the front of body 1, and a driven wheel opposite thereto is arranged at the rear of body 1;

[0050] Tilling rotating shaft 3, connected to body 1 through rotating arm 31;

[0051] Drive motor 4, fixed at the front of body 1, providing the main power source for the device;

[0052] Leveling rotating shaft 5, arranged at the rear side of tilling rotating shaft 3;

[0053] Feeding device 6, fixed inside body 1 and located at the rear side of leveling rotating shaft 5;

[0054] Mixing device 7, fixed inside body 1, arranged corresponding to feeding device 6, and a spraying component is arranged at the rear side of mixing device 7;

[0055] Transmission mechanism 8, connecting tilling rotating shaft 3, drive motor 4, leveling rotating shaft 5 and feeding device 6;

[0056] Rotating motor 9, connected to mixing device 7.

[0057] In this embodiment, the tilling rotating shaft 3 is rotatably connected to the body 1 through the rotating arm 31 and is connected to the drive motor 4 through the transmission mechanism 8. That is to say, driven by the rotating arm 31, the tilling rotating shaft 3 is driven to rotate, thereby adjusting the contact depth between the tilling rotating shaft 3 and the soil. Moreover, the rotating arm 31 and the transmission mechanism 8 do not affect each other. After the position of the tilling rotating shaft 3 is adjusted by the rotating arm 31, the drive motor 4 drives the tilling rotating shaft 3 to rotate through the transmission mechanism 8 to perform the soil turning work.

[0058] In this embodiment, a plurality of wavy steel bars 51 are annularly distributed on the outer ring of the finishing rotating shaft 5. The wavy steel bars 51 on the finishing rotating shaft 5 are located slightly below the land surface. Then, driven by the transmission mechanism 8, the finishing rotating shaft 5 drives the plurality of wavy steel bars 51 to rotate, breaking up the turned soil blocks while keeping the land surface flat.

[0059] In this embodiment, the feeding device 6 includes:

[0060] A bearing frame 61, fixed inside the machine body 1;

[0061] A storage bin 62, arranged on the top of the bearing frame 61;

[0062] A mixing and conveying bin 63, arranged at the bottom of the storage bin 62 and internally provided with a conveying rotating shaft 631;

[0063] A feeding pipe 64, connected to the bottom outlet of the mixing and conveying bin 63;

[0064] A ditching group 65, with multiple groups linearly distributed from front to back, and the contact depth with the soil of each group decreasing in turn;

[0065] Ditching assemblies 66, with multiple linearly distributed, constitute the ditching group 65. That is to say, when the whole equipment moves forward, the finishing rotating shaft 5 levels the land after soil turning, and then the ditching assemblies 66 in the ditching group 65 carry out ditching work. At the same time of ditching, the acid-base regulating powder in the storage bin 62 is conveyed into the mixing and conveying bin 63, and the transmission mechanism 8 drives the conveying rotating shaft 631 to rotate, conveying the acid-base regulating powder into the ditch through the feeding pipe 64. Since the contact depth of each group of the ditching group 65 with the soil changes in turn, that is, the acid-base regulating powder is conveyed to the soil from deep layer to surface layer in turn. Then, when the mixing device 7 mixes, it effectively ensures that the acid-base regulating powder is fully mixed with the soil, avoiding the phenomenon of uneven mixing caused by lack and failing to achieve the expected effect.

[0066] In this embodiment, all the ditching assemblies 66 in the ditching group 65 are not arranged in coincidence. That is to say, the distribution of the ditching assemblies 66 in the next ditching group 65 is set at intervals with reference to all the previous ditching groups 65. The setting of multiple ditching groups 65 gradually subdivides the intervals between the ditching assemblies 66. The multiple ditches with different depths enable the acid-base regulating powder to be distributed between the layers of the soil, facilitating the full mixing of the soil and the acid-base regulating powder.

[0067] In this embodiment, the ditching assembly 66 includes:

[0068] A ditching knife 661, in an arc shape, below the bearing frame 61 and penetrating into the soil;

[0069] The limiting sleeve 662 is fixed on the convex side of the ditching knife 661 and is connected to the material conveying pipe 64.

[0070] The connecting plate 663 is a telescopically adjustable structure that connects the ditching knife 661 and the bearing frame 61. Under the action of the connecting plate 663, the contact depth between the ditching knife 661 and the soil in each ditching group 65 can be actively adjusted. While the ditching knife 661 is ditching the land, the material conveying pipe 64 fixed on the limiting sleeve 662 conveys the acid-base regulating powder into the ditch, and through a plurality of ditching assemblies 66, the acid-base regulating powder is conveyed to different positions and depths of the soil for preliminary distribution.

[0071] In this embodiment, the mixing device 7 includes:

[0072] A plurality of mixing components 71 are linearly distributed and correspond to the ditching groups 65, and the contact depth between the bottom of the mixing components 71 and the soil increases in sequence.

[0073] The rotating shaft 72 is fixedly connected to the rotating motor 9 and connects a plurality of mixing components 71. Driven by the rotating motor 9, the mixing components 71 are driven by the rotating shaft 72 to perform reciprocating misaligned movements, so as to fully mix the soil and the acid-base regulating powder on the same horizontal plane. And under the sequential mixing of a plurality of mixing components 71, the soil is mixed from the surface layer to the deep layer in sequence to achieve the purpose of full mixing.

[0074] In this embodiment, the mixing component 71 includes:

[0075] The limiting frame body 711 is fixed inside the machine body 1;

[0076] Two moving parts 712 are symmetrically distributed and are slidably arranged on both sides of the limiting frame body 711;

[0077] Two rotating circular surfaces 713 are symmetrically distributed and are rotatably arranged at the center of the limiting frame body 711, and the middle part thereof is fixedly connected to the rotating shaft 72;

[0078] The moving panel 714 is correspondingly arranged with the moving part 712 and is fixed at the bottom of the moving part 712;

[0079] A plurality of inclined surfaces 715 are linearly distributed and are fixed at the bottom of the moving panel 714, and the inclination angles of the inclined surfaces 715 on the two side moving panels 714 are opposite. Driven by the rotating shaft 72, the rotating circular surface 713 rotates, driving the two side moving parts 712 to slide in opposite directions on the limiting frame body 711, and at the same time driving the bottom moving panel 714 to move, mixing the acid-base regulating powder in the ditch with the soil on both sides through the inclined surfaces 715. And the inclined surfaces 715 are inclined with respect to the moving panel 714, effectively reducing the resistance of the inclined surfaces 715 to the soil during the movement.

[0080] In this embodiment, tooth tracks 7121 are provided on the upper and lower sides of the moving member 712. A limiting tooth 7122 is provided at one end of the tooth track 7121, and the positions of the upper and lower limiting teeth 7122 are opposite to each other.

[0081] In this embodiment, tooth blocks 7131 are arranged in an arc shape on the rotating circular surface 713. The tooth blocks 7131 are engaged with the tooth tracks 7121, and the tooth blocks 7131 on the two rotating circular surfaces 713 on both sides are centrosymmetric about the connection center of the rotating circular surface 713. That is to say, the rotating circular surface 713 mainly drives the moving member 712 to move on the limiting frame 711 through the meshing between the tooth blocks 7131 and the tooth tracks 7121. Then, the tooth blocks 7131 are distributed differently on the two rotating circular surfaces 713 on both sides. That is, when the current-side tooth block 7131 is engaged with the lower tooth track 7121, the rear-side tooth block 7131 is engaged with the upper tooth track 7121, which drives the moving members 712 on both sides to move in the opposite direction. And under the limitation of the limiting teeth 7122, when the tooth blocks 7131 switch between the upper and lower tooth tracks 7121, effective limitation is carried out. It should be noted that to ensure the limiting effect of the limiting teeth 7122, the rotating circular surface 713 rotates clockwise.

[0082] During specific implementation, first, the position of the tilling rotating shaft 3 is adjusted through the rotating arm 31. Then, the positions of the ditching group 65 and the mixing device 7 are adjusted in sequence. The lowest point of the ditching group 65 corresponds to the lowest point of the tilling rotating shaft 3, and the subsequent ditching groups 65 are arranged in sequence upward. Then, the machine body 1 moves under the action of the driving wheel 2 and the driven wheel. At the same time, the driving motor 4 provides power for the tilling rotating shaft 3, the finishing rotating shaft 5, and the conveying rotating shaft 631. Thus, under the action of the tilling rotating shaft 3, the soil is turned over. Then, under the action of the finishing rotating shaft 5, the soil clods are broken and the land is leveled. Then, the ditching component 66 in the ditching group 65 carries out ditching work. And while ditching, the acid-base regulating powder is conveyed into the ditch through the material conveying pipe 64. Since the contact depth of each group of the ditching group 65 with the soil changes in sequence, that is, the acid-base regulating powder is conveyed into the soil from the deep layer to the surface layer. Then, under the action of a plurality of mixing components 71 corresponding to the ditching group 65, the soil is mixed from the surface layer to the deep layer in sequence. During the movement of the equipment, the acid-base regulating powder in the soil layer is mixed in sequence. And after mixing, water is sprayed through the spraying component to moisten the mixed soil and promote the absorption of the acid-base regulating powder by the soil.

[0083] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
