Description

Technical Field

[0001] The present invention relates to the technical field of agricultural fertilization, and more specifically, to a fertilization device with a soil turning structure for agricultural planting. Background Art

[0002] Fertilizer devices are divided into manual fertilizer devices and mechanical power fertilizer devices. Mechanical power fertilizer devices are often used to fertilize the soil before crops are sown and germinated. Once crops grow in the soil and need secondary fertilization, the crops are usually planted in the field in the form of a rectangular array. Large mechanical power devices are likely to crush the crops when fertilizing. When using a small manual fertilizer device to fertilize the soil, the manual fertilizer device can move along the ridges of the field without crushing the crops.

[0003] Existing manual fertilization devices include drum type and direct insertion type. During the use of the drum type manual fertilization device, an equal amount of granular fertilizer is generally buried near the root system of crops in an equidistant manner. However, the soil fertility in different areas of the farmland is not the same, and the growth of crops is also different. The equidistant and equal amount of fertilization will lead to excessive fertilization in areas with high soil fertility, resulting in excessive soil fertilization, while insufficient fertilization in areas with low soil fertility will lead to lack of nutrition for crops in the soil of this area. The above two situations will lead to reduced crop yields and even affect the normal operation of farmland rotation or continuous cropping systems. Summary of the invention

DETAILED DESCRIPTION

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0035] Existing manual fertilization devices bury equal amounts of fertilizers near the roots of crops in an equidistant manner. However, in reality, the soil fertility of different areas in the farmland is not the same. This form of fertilization will lead to excessive fertilization in areas with high soil fertility, resulting in excessive soil fertilization, while insufficient fertilization in areas with low soil fertility will cause the crops in the soil in this area to lack nutrition. The above two situations will lead to reduced crop yields and even affect the normal operation of farmland rotation or continuous cropping systems.

[0036] Embodiment 1: A fertilizing device with a soil turning structure for agricultural planting, such as Figure 1-Figure 5As shown, it includes a bracket 1, the bracket 1 is fixedly connected to a hopper 101, the bracket 1 is provided with an injection channel 102 connected to the hopper 101, the bracket 1 is fixedly connected to a shell 103 connected to the injection channel 102, the hopper 101 and the shell 103 are both made of transparent materials, which are used to observe the amount of fertilizer in the hopper 101 and the shell 103, the bracket 1 is rotatably connected to a handle 104 symmetrically distributed front and back, the rear side of the front handle 104 is fixedly connected to a first extrusion rod 105, and a second extrusion rod 106 that is extruded and matched with the first extrusion rod 105 is slidably connected in the bracket 1, so as to Figure 3 As a reference, the horizontal cross-sections of the first extrusion rod 105 and the second extrusion rod 106 are both wedge-shaped. When the first extrusion rod 105 rotates counterclockwise, the first extrusion rod 105 rotates and squeezes the second extrusion rod 106 to move backward. A first hydraulic telescopic rod 107 is fixedly connected in the bracket 1. When the first extrusion rod 105 rotates 160° counterclockwise, the telescopic end of the first hydraulic telescopic rod 107 shrinks to the limit state, so that the maximum rotation angle of the first extrusion rod 105 is limited to 160°. An elastic member is fixedly connected between the second extrusion rod 106 and the fixed part of the first hydraulic telescopic rod 107, wherein the elastic member is a compression spring. The telescopic end of the first hydraulic telescopic rod 107 is fixedly connected to the second extrusion rod 106. A spring with a through hole in the middle is fixedly connected in the housing 103. A support plate 108 is provided, in which a second hydraulic telescopic rod 109 connected to the first hydraulic telescopic rod 107 through a conduit is fixedly connected, and a limiting plate 110 slidably connected to the shell 103 is fixedly connected to the telescopic end of the second hydraulic telescopic rod 109 through a connecting rod, and the limiting plate 110 is provided with a trapezoidal hole 111, and the area of ​​the trapezoidal hole 111 gradually decreases from right to left, and is used to adjust the flow rate of fertilizer during the movement of the trapezoidal hole 111. A connecting channel for connecting the trapezoidal hole 111 with the through hole of the support plate 108 is provided on the lower side of the shell 103, and the front-to-back maximum width of the trapezoidal hole 111 is the same as the front-to-back width of the connecting channel on the shell 103, and a soil turning component 3 for turning the soil is provided on the shell 103.

[0037] like Figure 1 , Figure 4 and Figure 6-Figure 8As shown, the soil turning assembly 3 includes a rotating ring 31, which is rotatably connected to the shell 103, and the upper limit of the rotating ring 31 is rotatably connected to a plurality of fixed plates 301 evenly distributed in the circumferential direction, and the rotating ring 31 is rotatably connected to a blocking plate 302 evenly distributed in the circumferential direction, and a torsion spring is fixedly connected between the blocking plate 302 and the rotating ring 31, and the number of the blocking plates 302 is the same as the number of the fixed plates 301, and the blocking plates 302 and the adjacent fixed plates 301 together form a triangular block containing a chamber inside, and the triangular block is provided with a sharp blade for shoveling soil at a position away from the center of the rotating ring 31, and the blocking plates 302 and the adjacent fixed plates 301 are connected to each other. The contact is counteracted, and the rotating ring 31 is provided with through holes which are evenly distributed in the circumference and are connected and matched with the connecting channels of the shell 103. The number of the through holes is the same as the number of the blocking plates 302. The through holes are located on the side of the adjacent fixed plates 301 and the adjacent blocking plates 302 close to the axis of the rotating ring 31. The blocking plates 302 are fixedly connected with limit rods 303 which are symmetrically distributed frontward and rearward. The lower side of the shell 103 is fixedly connected with limit protrusions 304 which are symmetrically distributed frontward and rearward. The limit rods 303 are squeezed and matched with the adjacent limit protrusions 304. When the limit rods 303 are rotated to contact with the limit protrusions 304 and are squeezed, the limit rods 303 are limited and rotate.

[0038] like Figure 6 , Figure 7 and Fig. 9 As shown, the blocking plate 302 is slidably connected with the baffle plate 4, and the front-to-back width of the baffle plate 4 is greater than the front-to-back width of the adjacent fixed plate 301, so that after the baffle plate 4 is inserted into the soil, the baffle plate 4 is used to turn out more soil, and a sharp blade for shoveling soil is provided at the position of the baffle plate 4 away from the rotating ring 31, and symmetrically distributed elastic members are fixed between the baffle plate 4 and the adjacent blocking plate 302, wherein the elastic members are tension springs, and the distance between the position of the baffle plate 4 away from the rotating ring 31 and the axis of the rotating ring 31 is L, and the distance between the position of the baffle plate 302 away from the rotating ring 31 and the axis of the rotating ring 31 is H, wherein L is always greater than H. Taking the lower baffle plate 4 as an example, the lowermost end of the lower baffle plate 4 is farther from the axis of the rotating ring 31 than the adjacent blocking plate 302, so as to deepen the excavation of the soil, thereby delivering fertilizer into the soil.

[0039] like Figure 5 , Figure 6 and Fig. 9As shown, the second hydraulic telescopic rod 109 is fixedly connected with a sliding rod 5 which is symmetrically distributed frontward and rearward, the sliding rod 5 is slidably connected to the support plate 108, the sliding rod 5 is slidably connected to the shell 103, the shell 103 is slidably connected with a sliding frame 501 which is symmetrically distributed frontward and rearward, a guide surface is provided on the lower side of the sliding frame 501, an inclined slide groove which is limitedly slidably matched with the adjacent sliding rod 5 is provided on the sliding frame 501, the sliding rod 5 drives the sliding frame 501 to move by squeezing the adjacent inclined slide grooves, the baffle 4 is fixedly connected with wedge blocks 502 which are symmetrically distributed frontward and rearward and are respectively squeezed and matched with the adjacent sliding frames 501, when the wedge blocks 502 rotate to contact with the guide surfaces of the adjacent sliding frames 501, along with the rotation of the wedge blocks 502, they are squeezed downward by the guide surfaces of the adjacent sliding frames 501.

[0040] When the operator needs to use the device to fertilize the soil where crops grow, the operator adds granular fertilizer into the hopper 101, so that the fertilizer enters the shell 103 along the injection channel 102, and then the operator holds the corresponding handles 104 with both hands, and drives the bracket 1 to move left by pushing the handles 104, the bracket 1 drives the shell 103 to move left, the shell 103 drives the rotating ring 31 to move left, and the rotating ring 31 drives the parts on it to move left, so that the circumferentially evenly distributed fixed plate 301 and the circumferentially evenly distributed blocking plate 302 are both moved to the left. The baffle plate 302 drives the adjacent baffle plate 4 to move leftward, and when the baffle plate 4 contacts the soil, the fixed plate 301, the adjacent baffle plate 302 and the adjacent baffle plate 4 are simultaneously affected by the gravity of the upper parts and the fertilizer and inserted into the soil, so that the fixed plate 301, the adjacent baffle plate 302 and the adjacent baffle plate 4 are blocked by the soil and relatively displaced with the shell 103 during the leftward movement, and the fixed plate 301, the adjacent baffle plate 302 and the adjacent baffle plate 4 jointly drive the rotating ring 31 to rotate, so that the rotating ring 31 synchronously rotates counterclockwise during the leftward movement (the rotation direction is Figure 1 as a reference to the front view).

[0041] When the rotating ring 31 moves to the left and rotates counterclockwise, the rotating ring 31 drives the parts on it to rotate. For example, the fixed plate 301, the adjacent blocking plate 302 and the adjacent baffle plate 4 inserted into the soil at the lower side, at this time, the through hole on the lower side of the rotating ring 31 rotates to align with the connecting channel of the shell 103, and the fertilizer in the shell 103 enters the through hole on the lower side of the rotating ring 31 along the through hole of the support plate 108, the trapezoidal hole 111 and the connecting channel of the shell 103 in sequence, and then the fertilizer falls between the fixed plate 301 and the adjacent blocking plate 302. Along with the rotation of the rotating ring 31, the rotating ring 31 drives the adjacent limiting rod 303 to rotate through the lower blocking plate 302, and the lower limiting rod 303 rotates and gradually squeezes the limiting protrusion 304, and the limiting protrusion 304 blocks the lower limiting rod 303, forcing the lower limiting rod 303 to rotate counterclockwise. The needle flips, and the lower limiting rod 303 drives the adjacent baffle plate 4 to flip counterclockwise through the adjacent blocking plate 302. The torsion spring of the blocking plate 302 rotates and accumulates force. The blocking plate 302 and the adjacent baffle plate 4 jointly squeeze the soil on its right side and gradually move away from the adjacent fixed plate 301. The blocking plate 302 drives the adjacent baffle plate 4 to flip, and the blocking plate 302 squeezes the adjacent fixed plate 301 during the rotation process, so that an opening appears on the lower side of the blocking plate 302 and the adjacent fixed plate 301, and the fertilizer between the fixed plate 301 and the adjacent blocking plate 302 falls into the soil. The blocking plate 302 and the adjacent baffle plate 4 are used to shovel the soil and directly pour the fertilizer into the soil to prevent the fertilizer from falling on the soil surface and volatilizing and losing due to high temperature or being washed away by rain. Along with the rotation of the rotating ring 31, the lower limiting rod 303 gradually rotates until it loses contact with the limiting protrusion 304.

[0042] When the lower limiting rod 303 rotates until it loses contact with the limiting protrusion 304, the through hole on the lower side of the rotating ring 31 and the connecting channel of the shell 103 are gradually misaligned and blocked, and the torsion spring of the lower blocking plate 302 drives it to reset, and the lower blocking plate 302 drives the adjacent limiting rod 303 to reset. When the operator pushes the bracket 1 to the left, the circumferentially evenly distributed blocking plates 302 contact the soil in turn and repeat the above steps to bury the fertilizer in the soil in equal amounts and at equal distances.

[0043] When the operator fertilizes the soil through the above steps, the operator rotates the front handle 104 to rotate counterclockwise and drive the first extrusion rod 105 to rotate. The first extrusion rod 105 rotates and squeezes the second extrusion rod 106 to move backward. The elastic member of the second extrusion rod 106 contracts. The second extrusion rod 106 drives the telescopic end of the first hydraulic telescopic rod 107 to move backward. The first hydraulic telescopic rod 107 injects its internal liquid into the second hydraulic telescopic rod 109 through the catheter, so that the telescopic end of the second hydraulic telescopic rod 109 contracts. The telescopic end of the second hydraulic telescopic rod 109 drives the limit plate 110 to move rightward through the connecting rod. 10 drives the trapezoidal hole 111 on it to move rightward, so that the projection area of ​​the trapezoidal hole 111 at the lower connecting channel of the shell 103 gradually decreases. When the next through hole on the rotating ring 31 rotates to be connected with the trapezoidal hole 111, the amount of fertilizer entering the through hole on the lower side of the rotating ring 31 through the trapezoidal hole 111 is reduced, thereby changing the amount of fertilizer injected into the soil, so as to adapt to the amount of fertilizer applied to soils with different fertility. For example, if the operator observes with the naked eye that the crops in the area are growing well and the soil fertility is sufficient, the amount of fertilizer applied in the area can be reduced through the above-mentioned adjustment steps, thereby achieving the adjustment of the amount of fertilizer applied, thereby preventing excessive fertilization from causing root burns of crops and affecting the yield of crops.

[0044] During the rotation of the rotating ring 31, the blocking plate 302 rotated to the lower side drives the adjacent baffle plate 4 to rotate, and the baffle plate 4 drives the adjacent wedge block 502 to rotate until it contacts the adjacent sliding frame 501. The sliding frame 501 squeezes the adjacent wedge block 502 on the lower side, so that the wedge block 502 drives the adjacent baffle plate 4 to move downward, and the elastic part of the baffle plate 4 stretches and accumulates force. The baffle plate 4 moves downward to shovel the soil through its lower sharp edge, thereby increasing the buried depth of the fertilizer.

[0045] During the contraction of the telescopic end of the second hydraulic telescopic rod 109, the telescopic end of the second hydraulic telescopic rod 109 drives the two sliding rods 5 to move to the right. The sliding rod 5 moves to the right and squeezes the inclined slide groove of the adjacent sliding frame 501, so that the adjacent sliding frame 501 gradually moves upward. At this time, the telescopic end of the second hydraulic telescopic rod 109 contracts, which indicates that the soil in this area is fertile and the crops are growing well. Therefore, the sliding frame 501 moves upward, which shortens the distance that the sliding frame 501 squeezes the lower wedge block 502 to move downward, and shortens the distance that the baffle 4 moves downward, thereby preventing the baffle 4 from shoveling the soil too deep when the crops are growing well and the root system is well developed, which will damage the root system of the crops, thereby preventing the baffle 4 from shoveling the soil too deep, causing the fertilizer to directly contact the root system of the crops and cause root burns, thereby affecting the yield of the crops.

[0046] When the operator finishes fertilizing, the operator takes out the fertilizer in the hopper 101, the injection channel 102 and the housing 103 and collects and processes them, and then cleans the device for the next use.

[0047] If the moisture content in the external air is high during the storage of granular fertilizers, the granular fertilizers are easily affected by moisture and stick to each other, which can easily cause the granular fertilizers to clump and block the discharge port of the manual fertilization device, making it impossible for the fertilizers to be injected into the soil. Even if the agglomerated fertilizers can be discharged into the soil through the discharge port, the efficiency of the agglomerated fertilizers being absorbed by the soil will be reduced, which will lead to insufficient soil fertilization and affect the production of crops.

[0048] Embodiment 2: Based on embodiment 1, Figure 10-12 As shown, it also includes an outer gear ring 6, which is fixed to the rotating ring 31. The housing 103 is rotatably connected to a first gear 601 meshing with the outer gear ring 6. The first gear 601 is coaxially connected to a missing gear 602 located in the housing 103. When the missing gear 602 is meshed with the second gear 603, the missing gear 602 rotates and drives the second gear 603 to rotate. The torsion spring of the second gear 603 stores force. When the missing gear 602 loses meshing with the second gear 603, the torsion spring of the second gear 603 resets and drives it to reset, so as to realize the reciprocating rotation of the second gear 603. The housing 103 is rotatably connected to a first gear 601 that is transmission-matched with the missing gear 602. The second gear 603, a protective shell wrapped around the missing gear 602 and the second gear 603 is fixedly connected in the shell 103, which is used to prevent the fertilizer in the shell 103 from contacting the missing gear 602 and the second gear 603, causing the fertilizer to be stuck between the missing gear 602 and the second gear 603. The second gear 603 passes through the protective shell of the shell 103 through the gear shaft and is fixedly connected to the rotating plate 604. The rotating plate 604 is provided with a linear array of symmetrically distributed leakage holes. The leakage holes are used to isolate large lumps of agglomerated fertilizer on the upper side of the rotating plate 604 during the rotation of the rotating plate 604. A torsion spring is fixedly connected between the gear shaft of the second gear 603 and the shell 103.

[0049] like Figure 11-Figure 15As shown, a guide block 7 is fixedly connected to the shell 103, and the middle part of the upper side of the guide block 7 is concave downward, so that the left and right sides of the guide block 7 form inclined surfaces for guiding the fertilizers on the left and right sides to the middle part of the guide block 7. The middle part of the guide block 7 is rotatably and slidably connected with a grinding ring 701. The guide block 7 is provided with a plurality of inclined holes connected with the through holes of the support plate 108. The middle part of the guide block 7 is provided with a truncated cone portion 702 located in the grinding ring 701. A gap is provided between the grinding ring 701 and the truncated cone portion 702. The gap gradually decreases from top to bottom, and is used to grind the agglomerated fertilizer layer by layer from top to bottom. The inclined hole of the guide block 7 is connected to the gap, a plurality of first protrusions 703 evenly distributed in the circumferential direction are fixedly connected to the lower side of the grinding ring 701, and a plurality of second protrusions 704 evenly distributed in the circumferential direction are fixedly connected to the upper side of the guide block 7. The number of the first protrusions 703 is the same as the number of the second protrusions 704. The first protrusion 703 is squeezed and matched with the adjacent second protrusion 704. The shapes of the first protrusion 703 and the second protrusion 704 are both curved semi-disc-shaped. When the first protrusion 703 squeezes the adjacent second protrusion 704, the first protrusion 703 moves upward along the adjacent second protrusion 704 as the first protrusion 703 moves.

[0050] like Fig.10 , Fig.13 and Fig.14 As shown, the shell 103 is rotatably connected to a third gear 8 meshing with the outer gear ring 6, and the third gear 8 penetrates into the shell 103 and the guide block 7 through the gear shaft, and the gear shaft of the third gear 8 is fixedly connected to a reciprocating telescopic rod 801, wherein a spherical limit block is provided in the fixed part of the reciprocating telescopic rod 801, and an elliptical closed groove is provided on the telescopic end of the reciprocating telescopic rod 801, and the limit block moves in the closed groove, so that when the fixed part of the reciprocating telescopic rod 801 rotates, the limit block of the reciprocating telescopic rod 801 squeezes the closed groove on the telescopic end thereof, so that the telescopic end of the reciprocating telescopic rod 801 reciprocates and telescopes, and the telescopic end of the reciprocating telescopic rod 801 is fixedly connected to a rack 802 through a connecting rod, and the grinding ring 701 is fixedly connected to a rotating gear ring 803 meshing with the rack 802, and the height of the rack 802 is greater than the thickness of the rotating gear ring 803, which is used to provide a margin for the rotating gear ring 803 to slide up and down.

[0051] During the rotation of the rotating ring 31, the rotating ring 31 drives the outer gear ring 6 to rotate, the outer gear ring 6 drives the first gear 601 to rotate, the first gear 601 drives the missing gear 602 to rotate, when the missing gear 602 rotates to mesh with the second gear 603, the missing gear 602 drives the second gear 603 to rotate, the torsion spring of the second gear 603 stores force, and the second gear 603 drives the rotating plate 604 to rotate through the gear shaft, when the missing gear 602 rotates to lose meshing with the second gear 603, the torsion spring of the second gear 603 drives it to reset, and the second gear 603 drives the rotating plate 604 to reverse, during the rotation of the outer gear ring 6, the rotating plate 604 continues to reciprocate through the above steps, and the agglomerated fertilizer located on the upper side of the rotating plate 604 is screened out through the leakage hole of the rotating plate 604, and during the rotation of the rotating plate 604, the fertilizer entering the shell 103 leaks into the upper side of the guide block 7 through the leakage hole of the rotating plate 604.

[0052] When the fertilizer moves to the upper side of the guide block 7, the fertilizer enters into the gap between the grinding ring 701 and the truncated cone portion 702 along the inclined surfaces on the left and right sides of the guide block 7. The outer gear ring 6 drives the third gear 8 to rotate during the rotation process. The third gear 8 drives the fixed part of the reciprocating telescopic rod 801 to rotate through its gear shaft, so that the telescopic end of the reciprocating telescopic rod 801 reciprocates. The telescopic end of the reciprocating telescopic rod 801 drives the rack 802 to move back and forth through the connecting rod. The rack 802 drives the rotating gear ring 803 to reciprocate. The rotating gear ring 803 drives the grinding ring 701 to rotate, and the fertilizer in the gap between the grinding ring 701 and the truncated cone portion 702 is ground to prevent the fertilizer from agglomerating and causing it to be absorbed too slowly after entering the soil, thereby reducing the effective utilization rate of the fertilizer.

[0053] During the fertilizer grinding process, the grinding ring 701 drives all the first protrusions 703 thereon to rotate. When the first protrusion 703 rotates to contact the adjacent second protrusion 704, the first protrusion 703 is blocked by the adjacent second protrusion 704 and moves upward along it. The first protrusion 703 and the adjacent second protrusion 704 move in opposite directions, so that the grinding ring 701 and the guide block 7 move in opposite directions. The fertilizer flows into the through hole of the support plate 108 along the inclined hole on the guide block 7, and then the ground fertilizer is temporarily stored on the support plate 108. 8 and the limiting plate 110, and then repeat the above steps. With the rotation of the rotating ring 31, the through hole on the lower side of the rotating ring 31 rotates to be aligned with the connecting channel of the shell 103, and the fertilizer in the shell 103 enters the through hole on the lower side of the rotating ring 31 along the through hole of the support plate 108, the trapezoidal hole 111, and the connecting channel of the shell 103 in turn, and then the fertilizer falls between the fixed plate 301 and the adjacent blocking plate 302, and finally the soil is shoveled through the above-mentioned blocking plate 302 and the fertilizer is directly poured into the soil.

[0054] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
