Description

Technical Field

[0001] The invention relates to the technical field of fertilization devices, in particular to an organic fertilizer variable fertilization device. Background Art

[0002] When fertilizing plants with organic fertilizers, the following two methods can be used. First, a linear groove is opened on the side of the plant, and organic fertilizer is buried along the linear groove and then backfilled and covered. Second, a circular groove is opened around the planting area of ​​each plant, and organic fertilizer is buried in the circular groove and then backfilled and covered.

[0003] When using straight trenches to bury organic fertilizers, you can directly drive a trencher to open and fill, which is efficient, but the fertilization effect is reduced. Using circular trenches to bury organic fertilizers can effectively increase the plant's absorption rate of organic fertilizers, improve the fertilization effect, and supplement plant nutrition more evenly. However, currently, circular trenches are mostly opened by manual excavation, manual fertilization and burial, which is inefficient and costly. When driving a trencher to open a circular trench and apply fertilizer, the trench opening diameter is also large, and the optimal fertilization distance cannot be achieved.

[0004] To this end, the present invention proposes an organic fertilizer variable fertilization device for performing circular fertilization on plants. Summary of the invention

[0028] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention in conjunction with the drawings in the specification.

[0029] In the following description, many specific details are set forth to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0030] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that mutually exclude other embodiments.

[0031] Embodiment 1, referring to Figures 1 to 5 , which is the first embodiment of the present invention. This embodiment provides an organic fertilizer variable fertilization device, including a lifting mechanism 1; a connecting frame 11 is provided on the lifting end of the lifting mechanism 1, and a mounting frame 12 is provided on the outer wall of the lifting mechanism 1. The lifting mechanism 1 is connected to an agricultural machine through the mounting frame 12, and the lifting mechanism 1 can control the lifting of the connecting frame 11. It should be noted that the lifting mechanism 1 can be a screw rod elevator or a chain elevator.

[0032] A storage mechanism 2, which is provided on the lifting mechanism 1; the storage mechanism 2 is used to store organic fertilizer; the storage mechanism 2 includes an annular silo 21 and an annular silo door 22 movably provided on the annular silo 21; the feeding of the organic fertilizer in the annular silo 21 can be controlled by controlling the opening and closing of the annular silo door 22.

[0033] A flexible connecting member 3, which is provided on the annular silo 21; in this embodiment, the flexible connecting member 3 can be a rubber belt, a steel chain, or a sling. A plurality of flexible connecting members 3 are provided and are circumferentially arrayed at the bottom of the annular silo 21.

[0034] A suspension member 4, which is connected to the flexible connecting member 3; a plurality of abutting blocks 42 are provided on the suspension member 4 and are circumferentially arrayed on the suspension member 4. The feeding operation can be realized by the abutting blocks 42 abutting against the annular silo door 22.

[0035] In use, the lifting mechanism 1 is connected to the agricultural machinery, and the agricultural machinery can move near the plants. First, the storage mechanism 2 is lifted above the plants by the lifting mechanism 1, and then the center of the annular silo 21 is aligned with the plants. The lifting mechanism 1 is used to control the annular silo 21 to descend. Under the action of gravity, the suspension member 4 is first suspended below the storage mechanism 2 through the flexible connection member 3 until the lifting mechanism 1 controls the storage mechanism 2 to descend until the suspension member 4 touches the ground. At this time, when the lifting mechanism 1 continues to control the storage mechanism 2 to descend, the annular hatch 22 and the abutting block 42 will approach until they fit. At this time, the annular hatch 22 can be lifted by the abutting block 42 abutting against it, thereby opening the annular hatch 22, so that the organic fertilizer stored in the annular silo 21 falls, realizing annular fertilization. By controlling the lifting mechanism 1 to lift the storage mechanism 2, the annular hatch 22 closes under the action of gravity and the feeding stops. By controlling the storage mechanism 2 to reciprocate up and down, the abutting block 42 intermittently abuts against the annular hatch 22 for feeding, and the amount of organic fertilizer during fertilization can be controlled, which is convenient for adjustment according to different growth states of the plants and different amounts of organic fertilizer required, thereby realizing variable fertilization, further improving the soil absorption effect, being more conducive to the growth of the plants, and when controlling the storage mechanism 2 to reciprocate up and down, the organic fertilizer stored in the storage mechanism 2 can be leveled, making the discharging more uniform.

[0036] Example 2, refer to Figures 1 - 6 , which is the second embodiment of the present invention. Different from the previous embodiment, the annular silo 21 includes an annular plate 211 and arc-shaped baffles 212 arranged in a circumferential array on the annular plate 211; the annular hatch 22 includes a connecting ring 221 and baffle plates 222 arranged in a circumferential array on the connecting ring 221; the baffle plates 222 are slidably connected to the arc-shaped baffles 212, the connecting ring 221 is slidably arranged on the outer wall of the annular plate 211, the baffle plates 222 and the arc-shaped baffles 212 are arranged at intervals, and the baffle plates 222 and the arc-shaped baffles 212 are arranged in one-to-one correspondence.

[0037] Specifically, the storage mechanism 2 further includes a spring 23 arranged on the annular silo 21. The elastic force of the spring 23 can make the connecting ring 221 tend to move towards the arc-shaped baffle 212. The spring 23 is sleeved on the outer wall of the annular plate 211, and the bottom end of the spring 23 abuts against the connecting ring 221.

[0038] In use, refer to Figure 2 , when the suspension member 4 is in a suspended state, under the action of the elastic force of the spring 23 and the gravity of the annular hatch 22, the baffle plates 222 are inserted between the arc-shaped baffles 212. At this time, the annular hatch 22 is in a closed state, and the organic fertilizer in the annular silo 21 will not fall. Refer to Figure 6When the abutment block 42 abuts against the baffle plate 222 to compress the spring 23, the connecting ring 221 slides on the outer wall of the annular plate 211. Since the baffle plate 222 and the arc baffle plate 212 are misaligned, the organic fertilizer can fall, forming an annular fertilization. When the annular silo 21 is lifted and lowered back and forth, the abutment block 42 intermittently abuts against the annular silo door 22, which can cause shaking, and the organic fertilizer on the baffle plate 22 can be shaken off, so as to facilitate unloading.

[0039] Since the organic fertilizer is stored in the storage mechanism 2, when applying fertilizer, the amount of material released when the friction block 42 is squeezed for the first time is the largest. As the content of fertilizer in the storage mechanism 2 decreases, the material released by subsequent squeezing of the friction block 42 will gradually decrease. Therefore, when the friction block 42 is squeezed for multiple times to apply fertilizer, the amount released by one squeezing is reduced as the number of squeezing times increases, which facilitates more accurate application and avoids excessive application of organic fertilizer. The amount of organic fertilizer released after each squeezing of the friction block 42 will decrease, so each fertilization is variable fertilization.

[0040] Example 3, reference Figures 1 - 6 , which is the third embodiment of the present invention, is different from the previous embodiment in that it also includes a rotating mechanism 5 arranged on the lifting mechanism 1, and the rotating mechanism 5 can control the storage mechanism 2 to rotate.

[0041] By driving the storage mechanism 2 to rotate through the rotating mechanism 5 and cooperating with the lifting mechanism 1 to lift, the material inside the annular silo 21 can be distributed more evenly, which is convenient for uniform material discharge, and when the storage mechanism 2 rotates, it is convenient to add organic fertilizer inside.

[0042] Specifically, the rotating mechanism 5 includes a fixed ring 51 arranged at the lifting end of the lifting mechanism 1, and a gear ring 52 rotatably arranged on the fixed ring 51, and also includes a driving motor 53 arranged on the fixed ring 51, and a gear 54 is provided on the driving motor 53; the gear 54 is meshedly connected with the gear ring 52, and the fixed ring 51 is connected to the lifting end of the lifting mechanism 1 through the connecting frame 11.

[0043] The operation of the driving motor 53 causes the gear 54 to rotate, and the gear 54 drives the gear ring 52 to rotate, so that the annular plate 211 arranged below the gear ring 52 rotates, and can drive the storage mechanism 2 to rotate.

[0044] Example 4, reference Figures 1 - 8 , which is the fourth embodiment of the present invention, is different from the previous embodiment in that it also includes a digging mechanism 6 rotatably arranged on the suspension member 4.

[0045] The storage mechanism 2 is controlled to rotate by the rotating mechanism 5, and the storage mechanism 2 is connected to the suspension member 4 through the flexible connecting member 3, thereby driving the suspension member 4 to rotate together. When the suspension member 4 rotates, the soil on the ground is excavated by the digging mechanism 6, thereby facilitating the excavation of the annular pit and placing the organic fertilizer.

[0046] It should be noted that, since the flexible connector 3 is a flexible structure, at the beginning of the rotation of the storage mechanism 2, the suspension member 4 will cause the flexible connector 3 to be slightly twisted during rotation due to its own inertia. When the digging mechanism 6 contacts the soil, if the soil is hard, the reaction force provided by the digging mechanism 6 will assist the flexible connector 3 to further twist. After the flexible connector 3 is twisted, the distance between the digging mechanism 6 and the storage mechanism 2 is reduced, thereby changing the depth of the digging mechanism 6 embedded in the soil. By reducing the depth of excavation during rotation, the rotation of the digging mechanism 6 is guaranteed, which is effective. It has a certain buffering capacity, and if forced excavation is required, it only needs to be lowered through the lifting mechanism 1 when the digging mechanism 6 rotates. Since the flexible connecting member 3 will be twisted when the digging mechanism 6 digs, there will be an angle deviation between the storage mechanism 2 and the suspension member 4, and the resistance block 42 will be misaligned with the baffle plate 222 through the angle deviation. At this time, it only needs to be lowered until the resistance block 42 and the arc baffle plate 212 are in contact, and downward pressure is applied. The flexible connecting member 3 provides pulling force to drive the digging mechanism 6 to rotate, thereby achieving more powerful excavation and facilitating the opening of the annular groove.

[0047] Furthermore, a limiting rod 24 is provided on the arc-shaped baffle plate 212 ; the suspension member 4 includes a counterweight ring 41 , and an arc-shaped groove 411 provided on the counterweight ring 41 ; the arc-shaped groove 411 and the limiting rod 24 are slidably connected.

[0048] When in use, the counterweight ring 41 can be limited by the cooperation between the limiting plug rod 24 and the arc groove 411, thereby increasing the stability of the suspension member 4 during rotation.

[0049] It should be noted that, since the hanging member 4 is placed directly below the storage mechanism 2 when the fertilizer is added, it may cause obstruction to the organic fertilizer, causing some fertilizer to accumulate on the hanging member 4. After the feeding operation is completed, the storage mechanism 2 is controlled to rise, and then the storage mechanism 2 is controlled to rotate by the rotating mechanism 5. During the rotation of the storage mechanism 2, the organic fertilizer accumulated on the hanging member 4 can be shaken off by slightly twisting the flexible connecting member 3.

[0050] Example 5, reference Figures 1 - 8, which is the fifth embodiment of the present invention. Different from the previous embodiment, a support portion 421 and a boss portion 422 are provided on the abutting block 42; a blanking gap 213 is provided between adjacent arc-shaped baffles 212; a separation gap 223 is provided between adjacent material blocking plates 222; the width of the blanking gap 213 is smaller than the width of the separation gap 223.

[0051] The cross-sectional area of the boss portion 422 gradually increases from bottom to top. Therefore, under the action of the support portion 421 and the boss portion 422, when the upper surface of the boss portion 422 abuts against the arc-shaped baffle 212, a relatively large abutting area can be achieved, increasing the service life of the structure, with uniform force. And because the cross-sectional area of the boss portion 422 gradually decreases from top to bottom, when the boss portion 422 abuts against the material blocking plate 222, a larger space can be provided for the falling of organic fertilizer after the boss portion 422 is inserted, facilitating the dropping of organic fertilizer.

[0052] It should be noted that the width of the blanking gap 213 is small while the width of the separation gap 223 is large, which means that the arc length of the arc-shaped baffle 212 is large and the arc length of the material blocking plate 222 is small. Therefore, after the flexible connecting member 3 is twisted, the abutting block 42 is more likely to be misaligned with the material blocking plate 222, ensuring that during the excavation process of the earth excavation mechanism 6, the abutting block 42 will not cause material feeding and fertilization due to abutting against the material blocking plate 222.

[0053] Example 6, referring to Figures 1 - 8 , which is the sixth embodiment of the present invention. Different from the previous embodiment, the earth excavation mechanism 6 includes an earth excavation shovel 61 and a guiding plate 62 provided on the earth excavation shovel 61; during the rotation of the earth excavation shovel 61, the soil can be inclinedly excavated, and after the soil is dug up, it can be pushed to the periphery through the guidance of the guiding plate 62.

[0054] A limiting surface 611 is provided on the earth excavation shovel 61; a limiting block 43 is provided on the counterweight ring 41; a connecting shaft 412 is provided on the counterweight ring 41; the earth excavation shovel 61 is rotationally connected to the counterweight ring 41 through the connecting shaft 412.

[0055] The limiting block 43 can cooperate with the limiting surface 611 to limit the maximum deflection angle of the earth excavation shovel 61.

[0056] Referring to Figure 2 , at this time, the earth excavation shovel 61 is in a natural falling state. When earth excavation is required, the earth excavation shovel 61 is controlled to descend through the lifting mechanism 1. Until the earth excavation shovel 61 is about to contact the ground, the suspension member 4 is controlled to rotate. During the rotation, due to inertia, the earth excavation shovel 61 will generate a slight deflection, and the deflection direction is related to the rotation direction, facilitating the control of the deflection orientation of the earth excavation shovel 61. After the earth excavation shovel 61 is slightly deflected, at this time, the lifting mechanism 1 continues to control the earth excavation shovel 61 to descend. Under the gravity of the counterweight ring 41, finally, the front end of the earth excavation shovel 61 faces the ground, referring toFigure 7 At this time, the limiting plug rod 24 is also inserted into the soil, and the limiting block 43 and the limiting surface 611 are in a state of conflict. The excavation of the annular pit can be achieved by controlling the digging mechanism 6 to rotate through the rotating mechanism 5. In addition, the limiting plug rod 24 will also crush the soil during the rotation process. If the hardness of the soil is high during rotation, the counterweight ring 41 can be pulled up by the twisting of the flexible connecting member 3, thereby reducing the digging depth of the digging shovel 61 for buffering. When strong digging is required, it is only necessary to continue to lower the storage mechanism 2 so that the conflicting block 42 conflicts with the arc baffle 212. At this time, the downward force will directly act on the counterweight ring 41, thereby pressing the digging shovel 61 downward for rapid excavation. It should be noted that the limiting plug rod 24 during rapid excavation conflicts with the inner wall of the arc groove 411. The conflict between the two can reduce the force on the flexible connecting member 3, thereby avoiding excessive force on the flexible connecting member 3 and causing breakage and damage.

[0057] After the pit is excavated, the digging mechanism 6 is lifted up and separated from the annular pit. Under the action of gravity, the digging mechanism 6 will be deflected. During the deflection, the soil attached to the digging mechanism 6 can be thrown off, and the digging mechanism 6 can be swung in coordination with the reciprocating rotation of the rotating mechanism 5 to prevent the soil from sticking to the digging mechanism 6.

[0058] When it is necessary to place organic fertilizer, when the digging mechanism 6 is in the suspended state, the suspension member 4 is directly controlled to descend until the digging mechanism 6 contacts the soil. Figure 6 After the digging mechanism 6 hits the annular pit, the surrounding digging mechanism 6 forms a support for the counterweight ring 41. At this time, it continues to descend so that the baffle plate 222 hits the resistance block 42, and the feeding and fertilization are carried out.

[0059] After fertilization, refer to Figure 8 By controlling the rotation of the suspension member 4 and lowering the height of the storage mechanism 2, the digging mechanism 6 is deflected to the side away from the limit block 43. At this time, the digging mechanism 6 can dig the surrounding soil and perform backfilling operations. When the abutment block 42 abuts against the arc baffle 212, the limit rod 24 is inserted into the soil and rotated. In conjunction with the digging of the digging mechanism 6, it can also play a certain mixing role to mix the soil and organic fertilizer.

[0060] Example 7, reference Figures 1 - 8 , which is the seventh embodiment of the present invention, is different from the previous embodiment in that a scraper 63 is provided on the digging shovel 61.

[0061] Reference Figure 6 When feeding, the scraper 63 can increase the supporting area, thereby improving the stability of the counterweight ring 41 supported by the excavating mechanism 6.

[0062] Reference Figure 8, when backfilling, the scraper 63 can improve the soil scraping effect and the backfilling efficiency.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
