A wheat layered fertilizer machine convenient to adjust

Abstract

The present application relates to the field of agricultural machinery, especially to a wheat layered fertilizer applicator convenient to adjust. The technical problem to be solved is that frozen soil is easy to crack during fertilization, which causes the soil of the wheat root to be taken away together, exposes the wheat root to the outside, causes the wheat seedling to die, reduces the wheat yield, and the large frozen soil is not scattered, which affects the soil permeability, further affects the wheat root respiration, further, the soil temperature of the lower layer is low, which reduces the activity of the microorganism in the soil, and affects the fertilization effect. The technical scheme is a wheat layered fertilizer applicator convenient to adjust, which comprises a frame and a rotating shaft. The frozen soil is formed into holes by the sliding rod extrusion, which forms continuous holes on the left and right sides of the plow head, and the frozen soil is easy to crack along the holes on the left and right sides of the plow head, so as to avoid the frozen soil from being taken away together with the soil of the wheat root during the cracking of the frozen soil, which causes the wheat root to be exposed to the outside and die.

Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural machinery, in particular to a wheat layered fertilizer applicator convenient to adjust. BACKGROUND

[0002] In the process of planting wheat, especially in winter, "wax fertilizer" needs to be applied, that is, fertilizer is applied to wheat from the winter solstice to the winter solstice. In order to avoid evaporation of fertilizer, it is usually necessary to use a fertilizer machine to groove on both sides of the wheat and apply fertilizer into the groove. However, due to low temperature in the north, water in the soil crystallizes and then forms frozen soil. At this time, when the fertilizer machine grooves, the frozen soil is easily cracked, which causes the soil around the wheat roots to be taken away, so that the wheat roots are exposed outside, resulting in dead seedlings and reducing the yield of wheat.

[0003] Further, since the plowshare still has large blocks of frozen soil that have not been broken up when grooving in the wheat field, the soil permeability is affected, which in turn affects the respiration of the wheat root system. Furthermore, the lower layer of frozen soil is difficult to break and difficult to contact with the outside world, resulting in low soil temperature in the lower layer, which reduces the activity of microorganisms in the soil and affects the application effect of the fertilizer.

DETAILED DESCRIPTION

[0034] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0035] Example 1

[0036] like Figures 3-7 As shown, an easily adjustable wheat stratified fertilizer applicator includes a frame 1, a rotating shaft 2, plowshares 3, and a storage bin 4. The rotating shaft 2 is movably connected to the rear of the frame 1. At least three plowshares 3 are mounted on the rotating shaft 2. Each plowshare 3 has several discharge holes 3001. The storage bin 4 is mounted on the upper side of the frame 1. The storage bin 4 contains fertilizer. The storage bin 4 is connected to at least three plowshares 3 through a conveying pipe. Wheat is located between two adjacent plowshares 3.

[0037] It also includes sleeves 5, slide bars 6 and a crushing system; at least six sleeves 5 are installed on the frame 1; each sleeve 5 is movably connected to a slide bar 6; each slide bar 6 has a frustum-shaped lower side; each plow head 3 is located between two adjacent slide bars 6; the frame 1 is equipped with a crushing system, which crushes the frozen soil in front of the plow head 3, breaking the frozen soil into granules, thereby ensuring the soil's permeability.

[0038] The angle between the slide rod 6 and the horizontal plane is set to 45 degrees, and the upper side of the slide rod 6 is inclined towards the front of the frame 1 to reduce the pressure of the slide rod 6 on the frozen soil, thereby preventing the frozen soil at the hole from cracking into large pieces when the slide rod 6 moves forward, thus avoiding the exposure of the wheat roots.

[0039] The slide rod 6 is divided into upper and lower parts, which are rotatably connected. Each slide rod 6 has several protrusions 6001 at its lower part. Each sleeve 5 has a spiral groove 5001, which limits the lower part of the slide rod 6 to rotate spirally.

[0040] It also includes baffles 201; each slide rod 6 is rotatably connected with at least three baffles 201. The baffles 201 scrape the inner wall of the hole to loosen the frozen soil inside the hole and avoid affecting the respiration of wheat roots. When the lower part of the slide rod 6 rotates spirally, the baffles 201 scrape the inner wall of the hole in a spiral manner, further enhancing the soil loosening effect of the baffles 201 on the frozen soil.

[0041] The power assembly comprises a first motor 202, a belt pulley set 203 and a connecting rod set 204; the first motor 202 is fixed on the frame 1; three belt pulley sets 203 are installed on the middle part of the upper side of the frame 1; each belt pulley set 203 is fixed with the output shaft of the first motor 202; each belt pulley set 203 is hinged with two left-right symmetrical connecting rod sets 204; each connecting rod set 204 is hinged with the adjacent slide rod 6; the first motor 202 drives the belt pulley set 203 to rotate, and then drives the connecting rod set 204 to rotate, and then drives the slide rod 6 to slide in the sleeve 5.

[0042] The fertilizer application process is described in detail as follows: when applying "wax fertilizer", the user first fixes the frame 1 on the agricultural tractor, adjusts the height and adjacent spacing of the plow head 3, inserts the plow head 3 into the frozen soil, and places the plow head 3 between the two rows of wheat; at this time, the frame 1 is driven by the agricultural tractor to move forward on the wheat field, and then the plow head 3 is driven to move forward, so that the plow head 3 grooves the wheat field, and the fertilizer in the storage bin 4 is transported to the plow head 3 through the conveying pipe, and then is transported to the groove of the wheat field through the discharge hole 3001; in order to avoid the large frozen soil from cracking and taking the soil with the wheat roots away, the belt pulley set 203 is driven by the first motor 202 to rotate clockwise, and then the connecting rod set 204 is driven to rotate, and then the slide rod 6 is driven to slide up and down in the sleeve 5; when the slide rod 6 moves downward and inserts into the frozen soil, the frozen soil is extruded by the slide rod 6 to form a hole, so that when the frame 1 moves forward, the frozen soil on the left and right sides of the plow head 3 forms a continuous hole, which facilitates the cracking of the frozen soil along the hole on the left and right sides of the plow head 3, thereby avoiding the frozen soil from cracking and taking the soil with the wheat roots away, resulting in the exposure of the wheat roots to frost and the occurrence of dead seedlings; on this basis, when the frame 1 drives the slide rod 6 to move forward, since the angle between the slide rod 6 and the horizontal plane is forty-five degrees, and the upper side of the slide rod 6 is inclined to the front side of the frame 1, the extrusion force of the slide rod 6 on the frozen soil is reduced, thereby avoiding the frozen soil at the hole from cracking into large blocks when the slide rod 6 moves forward, thereby avoiding the exposure of the wheat roots, and further, when the slide rod 6 inserts into the frozen soil to form a hole, the frozen soil at the inner wall of the hole is harder, thereby affecting the respiration of the wheat roots; therefore, when the slide rod 6 moves downward, the baffle 201 is inserted into the frozen soil by adhering to the surface of the slide rod 6; when the slide rod 6 moves upward, the three baffles 201 contact the inner wall of the hole, so that the three baffles 201 are unfolded, and then the hole inner wall is scraped by the baffles 201, so as to loosen the frozen soil at the hole inner wall and avoid affecting the respiration of the wheat roots; on this basis, the lower part of the slide rod 6 is limited by the spiral groove 5001 to rotate spirally, i.e. when the slide rod 6 moves upward, the lower part of the slide rod 6 rotates clockwise spirally, thereby driving the baffle 201 to rotate clockwise, and then the hole inner wall is scraped spirally, thereby further enhancing the loosening effect of the baffle 201 on the frozen soil.

[0043] Embodiment 2

[0044] On the basis of embodiment 1, as shown in the figure, the crushing system comprises a crushing roller 301; at least three crushing rollers 301 are rotatably connected to the inner side of the frame 1; each crushing roller 301 is located between two adjacent slide rods 6, and the frozen soil on the front side of the plowshare 3 is crushed by the crushing roller 301, so that the frozen soil is crushed into granules, thereby ensuring the air permeability of the soil and avoiding affecting the respiration of the wheat root system. Figures 8-10

[0045] The crushing system further comprises a first protruding rod 302 and a second protruding rod 303; one first protruding rod 302 is fixedly connected to the opposite side of each two adjacent crushing rollers 301; the rotating shaft 2 is connected to the frame 1 through a torsion spring; at least four second protruding rods 303 are fixedly connected to the rotating shaft 2; each second protruding rod 303 is in sliding contact with the adjacent first protruding rod 302, and when the crushing roller 301 rotates counterclockwise, the first protruding rod 302 is driven to rotate, thereby contacting and pressing the second protruding rod 303, so that the plowshare 3 rotates upward, and the frozen soil in the lower layer is turned up by the rotation of the plowshare 3, thereby being fully crushed by the crushing roller 301, further ensuring the air permeability of the soil.

[0046] The crushing system further comprises a pressing plate 304; one pressing plate 304 is fixedly connected to the rear side of each plowshare 3, and when the plowshare 3 rotates clockwise, the pressing plate 304 rotates clockwise, thereby beating the frozen soil particles on the rear side of the plowshare 3, so that the surface layer of frozen soil particles is uniformly stressed, avoiding the blowing of frozen soil particles by strong winds.

[0047] ​The process of breaking up frozen soil is described as follows: when the plow head 3 is trenching in the wheat field, there are still large blocks of frozen soil that have not been broken up, which affects the soil permeability and in turn affects the respiration of the wheat roots. Therefore, with the right-to-left view as the reference, the second motor 305 drives the breaking roller 301 to rotate counterclockwise, and then the breaking roller 301 breaks up the frozen soil in front of the plow head 3, so that the frozen soil is broken into particles, thereby ensuring the soil permeability and avoiding affecting the respiration of the wheat roots. At the same time, the contact area between the frozen soil particles and the outside environment is increased, thereby increasing the soil temperature and the activity of microorganisms in the soil, and further enhancing the effect of fertilizer application. On this basis, when the breaking roller 301 rotates counterclockwise, the first protruding rod 302 is driven to rotate counterclockwise, and then contacts and presses the second protruding rod 303, so that the second protruding rod 303 rotates clockwise with the right-to-left view as the reference, thereby driving the shaft 2 to rotate and in turn driving the plow head 3 to rotate clockwise. At the same time, the torsional spring is stressed, and the frozen soil in the lower layer is turned up by the rotation of the plow head 3. When the breaking roller 301 continues to rotate, the first protruding rod 302 is separated from the second protruding rod 303, and the torsional spring drives the shaft 2 to reset the plow head 3. Thus, the frozen soil in the lower layer is turned up and broken up by the breaking roller 301, thereby further ensuring the soil permeability. On this basis, when the plow head 3 rotates clockwise, the pressing plate 304 rotates clockwise, thereby making the pressing plate 304 beat the frozen soil particles behind the plow head 3, so that the surface frozen soil particles are uniformly stressed and are not blown away by the wind.

[0048] Embodiment 3

[0049] On the basis of embodiments 1 and 2, as shown in Figure 1 , Figure 2 and Figures 11-12 , a protection system is further included, which comprises a protection plate 401. At least two protection plates 401 are fixed to the rear side of the frame 1. Each protection plate 401 is located between two adjacent first protruding rods 302. The protection plate 401 is located above the wheat, and the two sides of the plow head 3 are shielded by the protection plate 401 to avoid the broken frozen soil covering the wheat and affecting the growth of the wheat.

[0050] The width of the protection plate 401 is gradually narrowed from front to back, and the lower side of the protection plate 401 is inserted into the frozen soil. The protection plate 401 slides on the frozen soil, and the frozen soil particles on the left and right sides of the wheat are compacted through the guidance of the protection plate 401, thereby avoiding the collapse of the soil on both sides of the wheat during the soil breaking process, which causes the roots of the wheat to be exposed.

[0051] The left and right sides of the protection plate 401 are arc-shaped, and the protection plate 401 is made of elastic material. The first protruding rod 302 contacts and presses the protection plate 401, so that the left and right sides of the protection plate 401 move to the middle, and in turn the protection plate 401 presses the frozen soil particles on both sides of the wheat, thereby further ensuring the compacting effect of the frozen soil particles on both sides of the wheat.

[0052] The protection process of the broken frozen soil on the wheat is described in detail as follows: in the process of breaking the frozen soil, the frozen soil is easy to disperse to the left and right sides of the plowshare 3, and then easy to cover the wheat on the left and right sides of the plowshare 3, thereby affecting the growth of the wheat. Therefore, the protection plate 401 is used to shield the wheat on the left and right sides of the plowshare 3, so as to avoid the broken frozen soil covering on the wheat and affecting the growth of the wheat. On this basis, when the rack 1 drives the protection plate 401 to slide on the frozen soil, since the width of the protection plate 401 is gradually narrowed from front to back, the frozen soil particles inside the protection plate 401 are guided by the protection plate 401, so that the frozen soil particles on the left and right sides of the wheat are compacted, thereby avoiding the soil collapse on the left and right sides of the wheat in the soil loosening process, which causes the roots of the wheat to be exposed. Further, when the first convex rod 302 rotates counterclockwise, since the left and right sides of the protection plate 401 are provided with arc surfaces, and the protection plate 401 is made of elastic material, the protection plate 401 is contacted and extruded by the first convex rod 302, so that the left and right sides of the protection plate 401 move to the middle part, thereby extruding the frozen soil particles on the left and right sides of the wheat by the protection plate 401, and further ensuring the compaction effect of the frozen soil particles on the left and right sides of the wheat, thereby avoiding the soil collapse on the left and right sides of the wheat, which causes the roots of the wheat to be exposed.

[0053] The above embodiments are provided for those skilled in the art to implement or use the present application. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive idea of the present application, and thus the protection scope of the present application should not be limited by the above embodiments, but should be the maximum scope meeting the innovative features mentioned in the claims.
