Description

Technical Field

[0001] The invention belongs to the technical field of fertilization equipment, and more specifically is a special fertilization device for biological fertilizers. Background Art

[0002] Existing agricultural and forestry fertilization devices usually have a rotary tillage component in front to stir the soil, and then the hopper of the fertilization component follows the entire equipment travel route, sprinkles the corresponding fertilizer, and falls on the stirred soil, thereby realizing automatic fertilization.

[0003] Biofertilizer, also known as microbial fertilizer or bacterial fertilizer, refers to a type of fertilizer that utilizes the life activities of microorganisms to provide necessary nutrients for crops through their functions such as nitrogen fixation and decomposition of organic matter and minerals in the soil, while improving the soil environment. It is different from traditional chemical fertilizers because its ingredients contain active microorganisms that can continue to reproduce and function in the soil, thereby continuously providing nutrients for crops. Due to the characteristics of its internal microorganisms, when applying fertilizer, compared with traditional fertilizers, higher uniformity of fertilization is required. Otherwise, the excessive concentration of microorganisms will not only affect the rapid growth of the colony, but also greatly reduce the fertilizer effect it can produce. In particular, the microorganisms in biological fertilizers have requirements for the growth environment. Unlike traditional fertilizers that can be applied at will, they have vitality themselves. Therefore, they cannot be sprinkled on the surface or in the shallow layer that does not meet the depth. This is because microorganisms will be exposed to direct sunlight on the ground and it is difficult for them to survive. In the shallow layer that does not meet their growth needs, they may be restricted in growth and reproduction due to sunlight, as well as restrictions on moisture content and temperature, which will then affect the fertilizer effect. In particular, when some bacterial fertilizers have requirements for soil temperature, humidity and pH value, traditional fertilization equipment is even more difficult to solve this problem. Summary of the invention

[0004] In view of the technical status quo mentioned in the background technology, in order to overcome the corresponding defects in the prior art, the present invention particularly discloses a special fertilizing device for biological fertilizer, which can better solve the problem that the existing fertilizing equipment cannot evenly mix the bacterial fertilizer with the soil, and the fertilizer effect is poor after fertilization.

The rotary tillage component can dig a fertilizer ditch along a predetermined path. The fertilizer bin is used to pour bacterial fertilizer into the excavated fertilizer ditch.

The rotary tillage component is provided with two parallel components, the two rotary tillage components are coaxially installed on a rotating shaft, the two rotary tillage components are respectively installed in two inclined slides, and the rotating shaft is arranged along the width of the fertilizer ditch. The soil mixing component is located on the side of the second slide close to the edge of the fertilizer ditch, and the second slide can transport the soil mixed by the second rotary tillage component to this side. The soil covering component includes a scraper across the fertilizer ditch, and the scraper can backfill the soil on the side of the second slide close to the edge of the fertilizer ditch to the upper surface of the soil on which the bacterial fertilizer has been poured when moving forward.

[0006] Furthermore, the rotary tillage component includes a mounting arm, which is arranged along the inclination direction of the slide, and the bottom end of the mounting arm is rotatably mounted with a rotary tillage tooth assembly, and the top end of the mounting arm is rotatably mounted with a crushing reamer assembly, and the soil crushed by the crushing reamer assembly splashes upward into the fertilizer bin.

[0007] Furthermore, a spiral conveying shaft is also provided in the two slides, and one of the spiral conveying shafts conveys the soil turned up by the corresponding rotary tillage tooth assembly upward to the bottom of the crushing reamer assembly, so that the soil is further crushed and thrown upward.

[0008] Furthermore, after the top port of the second slide is deflected 90 degrees to one side, it is located above one side of the fertilizer ditch.

[0009] Furthermore, a fertilizer discharge pipe is connected to the bottom of the fertilizer bin. After the fertilizer discharge pipe extends obliquely downward toward the rear side, a fertilizer pipe is fixed with a bottom having a plurality of fertilizer holes or a fertilizer slit arranged along the length direction. The fertilizer pipe is arranged across the fertilizer ditch to evenly apply the bacterial fertilizer in the fertilizer ditch.

[0010] Furthermore, the stirring component includes a sliding plate, a vertical tube, a transverse connecting rod, and a longitudinal connecting rod, wherein the sliding plate is horizontally slidably installed at the upper part of the fertilizer bin, a plurality of drop holes are provided on the sliding plate, the sliding plate is connected to a driving device, and when the driving device drives the sliding plate to reciprocate in the horizontal plane, the entire plate edge of the sliding plate will never separate from the bin wall of the fertilizer bin, so that the fertilizer falls downward in an unfixed direction when the sliding plate moves translationally; the transverse connecting rod is fixed vertically to the surface of the vertical tube, and the longitudinal connecting rod is fixed vertically to the bottom of the transverse connecting rod, so that all the connecting rods and the vertical tubes can stir the spilled bacterial fertilizer together.

[0011] Furthermore, the vertical pipe is connected to an oxygen source or a water source, and both the oxygen source and the water source are provided with a heating device to heat the oxygen or water to a required temperature and spray the oxygen or water evenly in the fertilizer bin.

[0012] Furthermore, the top of the fertilizer bin has a through hole, through which the top of the vertical tube passes and can perform free translational movement. A flange is fixed to the top of the vertical tube, and the bottom surface of the flange is in rolling contact with the bin top through balls.

[0013] Furthermore, a connecting pipe section is provided on the upper end surface of the flange, the bottom port diameter of the connecting pipe section is larger than the top port diameter of the vertical pipe, and within the range of reciprocating movement of the vertical pipe in the horizontal plane, the top port of the vertical pipe is always located within the bottom port of the connecting pipe section; a wear-resistant sealing gasket is embedded in the bottom end surface of the connecting pipe section, and the wear-resistant sealing gasket is in sliding sealing contact with the top end surface of the flange.

[0014] Furthermore, moving wheels are provided at the bottom of the fertilizer bin, and the fertilization pipe is located behind all the moving wheels; the stirring component also includes a pair of crushing wheels, and a fertilizer discharge pipe is connected below the two crushing wheels.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the biological fertilizer special fertilizing device in the present invention is essentially different from the traditional fertilizing equipment, that is, the present fertilizing device turns over and crushes the soil and then transports it to the air above the ground to mix evenly with the scattered bacterial fertilizer, and then falls into the fertilizing ditch, which ensures the uniform dispersion of the microbial colonies of the bacterial fertilizer in the soil on the one hand; on the other hand, the contact and mixing with the soil are more sufficient, which is more conducive to the rapid reproduction of microorganisms; in addition, when necessary, the depth of the soil and bacterial fertilizer after the mixture falls and the thickness of the covered bacterial fertilizer soil can be changed, which can be achieved by changing the size of the corresponding first slide and its rotary tillage tooth assembly in the present invention during production, and changing the amount of soil transported into the fertilizer bin can change the covering thickness of the soil containing the bacterial fertilizer falling in the fertilizing ditch, that is, realizing the design control of the thickness of the fertilizer-effective soil layer, and the depth can be directly achieved by setting the corresponding first slide inclination during design and manufacturing, or the installation depth of the rotary tillage tooth assembly, and specific adaptive design adjustments can be made based on the specific type of bacterial fertilizer to achieve the purpose of the best fertilization effect.

[0016] Finally, the present invention can also improve the mixing uniformity of the bacterial fertilizer by jetting air through the vertical pipe, and adjust the humidity or temperature, or pH value by spraying water through the vertical pipe to meet the optimal growth environment requirements of the bacterial fertilizer.

DETAILED DESCRIPTION

[0020] Based on the several drawings in the embodiments of the present invention and referring to the following text description, a relatively clear and complete introduction of the technical scheme in the embodiments of the present invention can be made. However, it should be understood that the embodiments mentioned in this article are only one or several specific methods of the present invention, and not all implementation structures or method steps.

[0021] like Figure 1 As shown, as one of the embodiments of the present invention, a special fertilizing device for biofertilizer is introduced in detail, and its structure mainly includes a rotary tillage component 2 for turning and mixing the soil, a fertilizer bin 1 for containing bacterial fertilizer, and a soil covering component 3, which are arranged in sequence from front to back, and are used to backfill the soil after trenching into the trench. The rotary tillage component 2 can dig a fertilizer trench 17 along a predetermined path, and the fertilizer bin 1 is used to pour bacterial fertilizer into the excavated fertilizer trench 17. The soil covering component 3 backfills the soil on both sides of the fertilizer trench 17 to cover the bacterial fertilizer, thereby realizing the application of bacterial fertilizer. At the same time, the most critical thing is that in this embodiment, one of the biggest differences from the traditional equipment is that the above-mentioned rotary tillage components 2 are provided with two parallel ones, and the two rotary tillage components 2 are coaxially installed on a rotating shaft and rotate together to dig the fertilizer trench 17. At the same time, during installation, the two rotary tillage components 2 are respectively installed in two inclined slides 8, and the cross-section of the slide 8 can be as shown Figure 3 As shown, the rotating shaft passes through the two slides 8 along the width direction of the fertilizer groove 17, so that the soil turned over by the first rotary tillage component 2a is transported to the fertilizer bin 1 through the first slide 801, and then stirred by a stirring component arranged in the fertilizer bin 1, so as to achieve the mixing of soil and bacterial fertilizer, so that the soil mixed with bacterial fertilizer falls into the fertilizer groove 17, and then the purpose of uniformly distributing the bacterial fertilizer in the soil of a predetermined depth is achieved, which is convenient for the bacterial fertilizer to continue to reproduce and grow in the soil, and lays a solid foundation for the bacterial fertilizer to play a subsequent role.

[0022] like Figure 1-2 As shown, the soil covering component 3 is located on the side of the second slide 802 close to the edge of the fertilizer ditch 17, and the second slide 802 can transport the soil stirred by the second rotary tillage component 2b to this side, for example Figure 2 As shown, the top end of the second slide 802 is deflected 90 degrees to one side and is located above one side of the fertilizer ditch 17. Accordingly, the soil covering component 3 includes a scraper 301 across the fertilizer ditch 17. The scraper 301 must be tilted to facilitate the soil on that side to be fully backfilled into the fertilizer ditch 17. When the scraper 301 moves forward, it can backfill the soil on the side of the second slide 802 near the edge of the fertilizer ditch 17 to the upper surface of the soil where the bacterial fertilizer has been poured, that is, Figure 2 In the position shown, the scraper 301 of the soil covering component 3 is arranged on the right side so that the soil output by the second slide 802 can be fully covered in the fertilizer trench 17 to ensure that the fertilizer trench 17 is fully filled.

[0023] As one of the specific implementation structures, such as Figure 1 as well as Figure 5 As shown, the rotary tillage component 2 includes a mounting arm 19, which is arranged along the inclined direction of the slide 8 so as to output the soil upward. At the same time, a rotary tillage tooth assembly 201 is rotatably mounted at the bottom of the mounting arm 19 to quickly turn up the soil, which is then transported to a crushing reamer assembly 202 rotatably mounted at the top. The soil crushed by the crushing reamer assembly 202 splashes upward into the fertilizer bin 1, and then mixes with the bacterial fertilizer sprinkled downward in the fertilizer bin 1 in the air. Relatively speaking, the mixing is relatively uniform and sufficient. In the above embodiment, the two rotary tillage components arranged in parallel are specifically as follows: Figure 5 The rotary tilling tooth assembly 201a of the first rotary tilling component 2a, the rotary tilling tooth assembly 201b of the second rotary tilling component 2b, the crushing reamer assembly 202a of the first rotary tilling component 2a and the crushing reamer assembly 202b of the second rotary tilling component 2b are shown in the figure.

[0024] To facilitate the transportation of soil, a spiral conveying shaft (not shown in the figure) or an existing conveying element such as a conveyor belt can be further provided in the two slides 8. One of the spiral conveying shafts conveys the soil turned up by its corresponding rotary tillage tooth assembly 201 upward to the bottom of the crushing reamer assembly 202, so that the soil is further crushed and thrown upward, or sprinkled, and then evenly mixed with the falling bacterial fertilizer.

[0025] In order to better fertilize, Figure 1 As shown, the bottom of the fertilizer bin 1 is connected to a fertilizer discharge pipe 10, which extends obliquely downward toward the rear side to evenly spread the bacterial fertilizer. In addition, a fertilizer pipe 11 is fixed to the bottom of the fertilizer bin 1. The bottom of the fertilizer pipe 11 is provided with a plurality of fertilizer holes along the length direction, or a fertilizer pipe 11 with a fertilizer slit. The bacterial fertilizer falls from the fertilizer holes, or from the fertilizer pipe 11 through the fertilizer slit to form a curtain-like fertilizer falling area. In order to ensure comprehensive fertilization, the fertilizer pipe 11 is arranged across the fertilizer ditch 17 to evenly apply the bacterial fertilizer in the fertilizer ditch 17.

[0026] In practice, in order to further improve the uniformity of fertilization, an auger (not shown in the figure) can be axially installed in the fertilization pipe 11 to quickly spread the bacterial fertilizer throughout the fertilization pipe 11 .

[0027] When manufacturing, Figure 1 As shown, the stirring component includes a sliding plate 4, a vertical tube 5, a transverse connecting rod 6, and a longitudinal connecting rod 7, wherein the sliding plate 4 is horizontally slidably installed on the upper part of the fertilizer bin 1, and a plurality of drop holes are provided on the sliding plate 4 for the bacterial fertilizer to fall down. Initially, the bacterial fertilizer is located in the fertilizer bin above the sliding plate 4, and the bacterial fertilizer is supported by the sliding plate 4. Moreover, more specifically, the dropping method of the bacterial fertilizer is that the sliding plate 4 is connected to a driving device, and when the driving device drives the sliding plate 4 to reciprocate in the horizontal plane, the entire plate edge of the sliding plate 4 will never separate from the bin wall of the fertilizer bin 1, so that the sliding plate 4 always plays the role of supporting the bacterial fertilizer on the upper surface, thereby making it possible to When the sliding plate 4 moves in translation, the bacterial fertilizer passes through the drop hole and falls downward in an unfixed direction. In this way, the bacterial fertilizer can fully cover the entire fertilizer bin 1 when it falls, and it is more dispersed, which is convenient for uniform mixing with the soil. On the other hand, if the sliding plate 4 is stationary, the bacterial fertilizer is added into the fertilizer bin 1, which is likely to block the drop hole, resulting in the bacterial fertilizer being unable to fall normally, and the effect of the bacterial fertilizer being evenly scattered downward cannot be achieved. Therefore, a driving device is used to drive the sliding plate 4 to move back and forth, which can be specifically left and right reciprocating movement, front and back reciprocating movement, or left and right and front and back intermittent reciprocating movement. When installing, a hydraulic rod can be directly set in the corresponding direction for telescopic movement. As a recommended design structure, the driving device is preferably driven by a device such as a vibration motor, so that the sliding plate 4 can rotate in the left plane in the horizontal plane, that is, similar to the plane swing or shaking of the hand-held sieve in the plane when manually screening grains, so that the bacterial fertilizer can be scattered more dispersedly. In the above structural design, the vertical tube 5 is fixedly connected to the sliding disk 4, a transverse connecting rod 6 is fixed perpendicularly to the surface of the vertical tube 5, and a longitudinal connecting rod 7 is fixed perpendicularly to the bottom of the transverse connecting rod 6, forming a series of stirring rods, which can enable all the connecting rods and the vertical tube 5 to stir the spilled bacterial fertilizer together, so that the bacterial fertilizer is mixed with the soil during the falling process, and then mechanically stirred and mixed again, achieving the effect of secondary stirring and making the mixing more uniform.

[0028] As a groundbreaking design, Figure 1As shown, in order to meet the requirements of appropriate temperature and pH value of bacterial fertilizer, the vertical pipe 5 can be designed with multiple functions, that is, the vertical pipe 5 is connected to an oxygen source or a water source, and both the oxygen source and the water source are provided with a heating device to heat the oxygen or water to the required temperature, and evenly spray it in the fertilizer bin 1 through the spray hole 501, and the heating or pH value adjustment of the bacterial fertilizer and soil mixture can be achieved by spraying it in the fertilizer bin 1, so that the bacterial fertilizer can be propagated and grown in the soil in the best way. On the other hand, when oxygen is used, necessary oxygen can also be provided to some aerobic bacteria, so that they can be propagated in time after being buried in the ground to form a stable bacterial colony. These oxygen can be mixed in the air and transported together. When these gases are ejected from the vertical pipe 5, they play a role of lateral sweeping and then uniform mixing on the falling soil and bacterial fertilizer.

[0029] like Figure 1 In the above structural design, the top of the fertilizer bin 1 has a through hole 16, through which the top of the vertical tube 5 passes, and can freely translate or swing. A flange 12 is fixed to the top of the vertical tube 5, and the bottom surface of the flange 12 is in rolling contact with the bin top through the ball 15 to reduce friction during movement. In addition, Figure 4 The upper end surface of the flange 12 is provided with a connecting pipe section 13, the bottom end diameter of the connecting pipe section 13 is larger than the top end diameter of the vertical pipe 5, and within the range of the reciprocating movement of the vertical pipe 5 in the horizontal plane, the top end of the vertical pipe 5 is always located within the bottom end of the connecting pipe section 13, so that the two are always connected. In order to make it easier to seal, a wear-resistant sealing gasket 14 can be embedded in the bottom end surface of the connecting pipe section 13, and the wear-resistant sealing gasket 14 is in sliding sealing contact with the top end surface of the flange 12. The sealing gasket 14 can be a graphite gasket or washer that is both wear-resistant and has sealing properties.

[0030] Finally, in this embodiment, if Figure 1 As shown, at the bottom of the fertilizer bin 1, there are moving wheels 9, which are preferably moved forward in the trench of the excavated fertilizer trench 17. Specifically, corresponding driving elements can be installed, or the special fertilization device can be installed on some agricultural vehicles to achieve forward driving, digging trenches and fertilizing at the same time. In order to ensure that the bacterial fertilizer falls into the same depth layer range, the fertilizer pipe 11 is located behind all the moving wheels 9 to avoid being crushed by the moving wheels 9. In addition, the stirring component also includes a pair of crushing wheels 18, and a fertilizer discharge pipe 10 is installed below the two crushing wheels 18, so that the mixed soil bacterial fertilizer can be evenly stirred again and output to the fertilizer pipe 11 for uniform fertilization.

[0031] The present invention is not limited to the field involved in this implementation case. Some well-known structures or principles are not further described. However, ordinary technicians in the relevant field can theoretically know all the known technologies in this technical field before the application date or priority date, can fully master all the existing technologies in this technical field, and have the means and ability to apply these existing technologies for actual design and application. Under the technical inspiration given by this application, technicians can improve and implement the present invention more comprehensively based on their own abilities.

[0032] In addition, it should be pointed out that although the text and graphics of the above embodiments have shown the specific implementation scenarios of the present invention, for those skilled in the art, it is entirely possible to make a variety of obvious expansions and extensions to these embodiments without departing from the design concept of the present invention to form different embodiments, but this does not affect the scope of protection of the present invention, which is covered and embodied by the above-mentioned technical features and equivalent technical features.
