[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0036] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0037] This invention provides a moisture-proof and non-sticky small fertilizer applicator, such as... Figure 1-14 As shown, the moisture-proof and adhesive-resistant small fertilizer applicator includes: a frame housing 1 with an opening at the bottom and a fertilizer tank 2 fixedly installed inside the frame housing 1. The top of the fertilizer tank 2 is a feed inlet and the bottom is a discharge outlet. The moisture-proof and adhesive-resistant small fertilizer applicator also includes: a hydraulic cylinder 3 located on one side of the fertilizer tank 2 and fixedly connected to the inner wall of the top of the frame housing 1; a transmission housing 4 with a reciprocating mechanism fixedly installed on the output rod of the hydraulic cylinder 3; a digging scraper 5 telescopically located at the bottom of the transmission housing 4 for digging open fertilizer application pits; and a soil scraper cover 6 slidably sleeved on the digging scraper 5 for scraping off soil adhering to the digging scraper 5. The soil scraper cover 6 is located below the transmission housing 4. The upper and lower halves of the transmission housing 4 are rectangular in structure, the middle part is arc-shaped, and the lower half has a rectangular opening for the digging scraper 5 to slide.

[0038] It should be noted that in order to reduce damage to plants during plant growth, the current fertilization process requires first digging a hole in the soil, then spreading fertilizer into the hole, and finally covering it with soil. Although existing equipment can accomplish this, the success rate is usually low. In particular, during the digging process, because the soil usually contains moisture, the sticky soil tends to adhere to the equipment. The digging components with a large amount of soil adhering to them have greater resistance and are difficult to penetrate the soil. The effect is better in the early stage of digging, but the standard of the hole is poor in the later stage, which affects the penetration of fertilizer. Taking the patent document with authorization announcement number CN113115618B as an example, there is a problem of soil adhesion after the soil is removed by the soil-removing plate.

[0039] In this embodiment, the fertilizer tank 2 located inside the frame housing 1 is used to store fertilizer that needs to be applied. The transmission housing 4 on the output rod of the hydraulic cylinder 3 can be raised and lowered during use, thereby adjusting the operating height of the digging scraper 5 and the depth of digging according to the usage. The reciprocating mechanism drives the digging scraper 5 and the soil scraper 6 to move relative to each other, so that the digging scraper 5 can be lowered to a specified depth and then raised. The soil scraper 6 moves relative to the digging scraper 5, which can scrape off the residual soil on the digging scraper 5, thereby reducing adhesion and improving the digging effect.

[0040] To further improve the leveling of fertilized land, in another embodiment, the bottom of the pit-removing scraper 5 is provided with a storage groove, and a plow tooth plate 33 is slidably provided in the storage groove. The plow tooth plate 33 forms a soil-leveling rod through multiple notches, and at least two positioning holes 34 are provided on the plow tooth plate 33 for positioning bolts 35 on the pit-removing scraper 5.

[0041] In this embodiment, after the land has dried slightly after fertilization, people usually use a rake to integrate the land so that the fertilizer can be better mixed with the soil. This step is usually performed before planting. At this time, people slide the plow plate 33 out of the storage groove, and then fix it with positioning bolts 35 and positioning holes 34 so that the device can move to rake the land. It can be used for multiple purposes and reduces the investment cost.

[0042] In order to more accurately control the amount of fertilizer applied during fertilization, in another embodiment, a soil moisture detection sensor 36 for detecting soil moisture is detachably installed at the bottom of the plowshare 33, and a soil moisture data processor 37 for processing the detection information of the soil moisture detection sensor 36 is provided inside the frame housing 1.

[0043] In this embodiment, since the content of trace elements in the soil varies in different regions, the soil moisture detection sensor 36 can detect the soil moisture while the shovel scraper 5 is making holes. After detection, the data is transmitted to the soil moisture data processor 37 for analysis. Then, the rotation speed of the feeding motor 28 on the fertilizer tank 2 is controlled, thereby controlling the amount of fertilizer discharged, reducing waste and avoiding fertilizer shortage, and improving the fertilization effect.

[0044] In a further preferred embodiment of the present invention, the reciprocating mechanism includes: a drive shaft 7 rotatably mounted inside the transmission housing 4 and arranged parallel to the ground; a cam 8 disposed inside the transmission housing 4 and fixedly sleeved on the drive shaft 7; a tile 9 disposed inside the transmission housing 4 and fixedly connected to the top of the pit-removing scraper 5, the tile 9 being located below the rotation trajectory of the cam 8; a long screw 10 slidably mounted on the inner wall of the top of the transmission housing 4 and having a nut, the bottom end of the long screw 10 being fixedly connected to the tile 9; a spring 11 disposed on the top of the transmission housing 4 and slidably sleeved on the long screw 10 and pressed by the nut; and a driven mechanism disposed on the transmission housing 4 and the drive shaft 7 for driving the soil scraper 6.

[0045] In this embodiment, the reciprocating mechanism, through the rotation of the drive shaft 7, drives the cam 8 to rotate. When the cam 8 rotates, it pushes the tile 9, which, together with the long screw 10 and the spring 11, enables the pit-digging scraper 5 to extend and retract up and down, and to reciprocate. The operation process reduces manual intervention, is more labor-saving, and makes the pit digging more uniform.

[0046] In a further preferred embodiment of the present invention, the driven mechanism includes: a second cam 12 disposed on one side of the transmission housing 4 and fixedly sleeved on the drive shaft 7; a second tile 13 disposed below the second cam 12 and slidingly contacting the side of the transmission housing 4, the second tile 13 being fixedly connected to the side of the scraper cover 6; a support frame 14 fixedly installed on both sides of the transmission housing 4 for mounting a second long screw 15, the second long screw 15 slidingly passing through the second tile 13 and being limited by a nut; and a second spring 16 slidably sleeved on the second long screw 15 and located between the support frame 14 and the second tile 13; wherein the second cam 12 and the first cam 8 have the same structure, both being bidirectional cam structures, and the second cam 12 and the first cam 8 are arranged in a cross shape, the upper part of the second tile 13 has an "Ω" structure, and the lower part has an "L" shape structure.

[0047] In this embodiment, the driven mechanism moves in accordance with the rotation of the drive shaft 7. Cam 2 12 and Cam 1 8 are arranged in a cross shape, so that the pushing process of the two cams is staggered, which can avoid the pit-digging scraper 5 being affected. Tile 2 13 is pushed by Cam 2 12. With the use of long screw 2 15 and spring 2 16, the soil scraper 6 slides relative to the pit-digging scraper 5, which can remove more adhering soil on the pit-digging scraper 5 and ensure the effect of digging pits.

[0048] In a further preferred embodiment of the present invention, the transmission housing 4 is provided with a drive mechanism for driving the drive shaft 7 to rotate and the equipment to move. The drive mechanism includes: at least two axles 17 rotatably mounted on the frame housing 1; a drive motor 18 fixedly mounted in the frame housing 1, wherein a small sprocket 19 is fixedly sleeved on the output shaft of the drive motor 18 and on any one of the axles 17; and a sprocket disc 20 fixedly mounted on either end of the drive shaft 7 and connected to the two small sprockets 19 by a synchronous chain.

[0049] In this embodiment, the power for the device's movement and the power for the reciprocating mechanism both come from the drive mechanism. The drive mechanism drives the linkage, which can ensure consistency and uniformity in movement and digging. During use, the output shaft of the drive motor 18 drives the corresponding small sprocket 19 to rotate. At this time, the small sprocket 19 uses a synchronous chain to drive another small sprocket 19 and the sprocket disc 20 to rotate, thereby realizing the synchronous rotation of the wheel axle 17 and the drive shaft 7, realizing the intermittent movement of movement, digging, and scraping mud.

[0050] In a further preferred embodiment of the present invention, a second hydraulic cylinder 21 is provided on one side of the synchronization chain and is fixedly connected to the frame housing 1. A tensioning wheel 22 for tensioning the synchronization chain is provided on the output rod of the second hydraulic cylinder 21.

[0051] In this embodiment, in order to accommodate the change in the position of the sprocket disc 20 caused by the lifting and lowering of the transmission housing 4 by the hydraulic cylinder 3, the length of the synchronous chain changes. At this time, the hydraulic cylinder 21 needs to be operated synchronously to adjust the tensioning wheel 22 to press against the synchronous chain, ensuring smooth operation.

[0052] In a further preferred embodiment of the present invention, an assembly frame 23 is fixedly installed on one side of the transmission housing 4, and a soil covering plate 24 is provided on the rear walking side of the ditch scraper 5. An adjustment port 25 is provided on the assembly frame 23, and an adjustment bolt 26 for adjusting the height of the soil covering plate 24 by means of the adjustment port 25 is provided on the side of the soil covering plate 24 and the assembly frame 23; wherein, the soil covering plate 24 is arranged in a "U" shape, and the opening of the "U" shape is consistent with the walking side.

[0053] In this embodiment, after digging the pit and applying fertilizer, the pit needs to be filled with a soil covering board 24. During use, the soil covering board 24 is used at the same height as the ground. The adjusting bolt 26 can be raised and lowered using the adjusting port 25 to adjust the height of the soil covering board 24, thereby ensuring that it can be covered smoothly after the soil is covered.

[0054] In a further preferred embodiment of the present invention, a feeding wheel 27 is rotatably installed inside the discharge port of the fertilizer tank 2, and a feeding motor 28 is fixedly installed on the fertilizer tank 2. The output shaft of the feeding motor 28 is connected to the output end of the feeding wheel 27.

[0055] In this embodiment, during fertilization, the output shaft of the feeding motor 28 drives the feeding wheel 27 to rotate, and the fertilizer is evenly discharged through the blade groove on the feeding wheel 27. The feeding motor 28 is used in conjunction with the soil moisture detection sensor 36 and the soil moisture data processor 37 to locate the amount of fertilizer applied. Only the rotation speed of the feeding motor 28 needs to be adjusted.

[0056] In a further preferred embodiment of the present invention, a receiving hopper 29 is detachably installed outside the discharge port of the fertilizer tank 2, and a guide pipe 30 is integrally and fixedly connected to the bottom of the receiving hopper 29. The discharge end of the guide pipe 30 extends between the pit scraper 5 and the soil covering plate 24.

[0057] In this embodiment, the receiving hopper 29 is used to receive the fertilizer discharged from the fertilizer tank 2, and then guides it into the pit through the guide pipe 30 to achieve topdressing.

[0058] In a further preferred embodiment of the present invention, at least two axles 17 are fixedly mounted with a traveling wheel 31 at both ends, and the outer rim of the traveling wheel 31 is provided with an anti-slip layer.

[0059] In this embodiment, the anti-slip layer on the outer side of the walking wheel 31 can prevent slipping during walking and reduce energy loss.

[0060] In a further preferred embodiment of the present invention, a controller 32 is provided on one side of the frame housing 1, a cover for sealing the feed inlet of the fertilizer tank 2 is hinged to the top of the frame housing 1, a handle is fixedly installed on the frame housing 1, and a battery pack 38 is provided inside the frame housing 1.

[0061] In this embodiment, the controller 32 is used to control the overall operation of the equipment, the cover seals the fertilizer tank 2, and the handle is used to hold and operate the device.

[0062] In summary, this device can remove the soil adhering to the digging components while digging the hole, improving the standard of digging and the fertilizer penetration effect, thus ensuring that the plants can successfully absorb nutrients.

[0063] Compared with related technologies, this device uses a soil scraper 6 outside the digging scraper 5 to scrape away the adhering soil, which improves the standard of digging and the fertilizer penetration effect, thus ensuring that the plants can successfully absorb nutrients. The operation of the digging scraper 5 and the soil scraper 6 are driven by the same set of reciprocating mechanisms, which can achieve synchronization and have good consistency in use. At the same time, the power for the equipment to move and the power for the reciprocating mechanism are both from the drive mechanism, and the drive mechanism drives the linkage, which can ensure the consistency of movement and digging, and is relatively uniform.
