Description

Technical Field

[0002] Agricultural fertilizer spreaders are devices used to evenly distribute fertilizers on farmland or gardening sites. Their purpose is to ensure that plants can obtain the right amount of nutrients to promote healthy growth and high yields. Agricultural fertilizer spreaders are widely used in irrigation and fertilization of mountain fruit trees, field vegetable grains and cash crops, facility agriculture cultivation, greenhouse fruit trees, greenhouse vegetables, and other crops with good economic benefits. They can reduce the number of workers and reduce labor intensity. Through precise irrigation and fertilization management, they can realize the accumulation of agricultural big data, continuously optimize irrigation and fertilization strategies, and ultimately achieve standardized production that saves water and fertilizer.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 13 In an embodiment of the present invention, a fast-penetrating agricultural fertilizer fertilization device includes a fertilizer trolley 10, a fertilizer supply mechanism 20 and a fertilizer mechanism 40 disposed on the fertilizer trolley 10. The fertilizer trolley 10 includes a vehicle body 11 and wheels 15 mounted on the vehicle body 11. When the wheels 15 are rotating, they drive the vehicle body 11 to move on the surface of the soil 70, so that the vehicle body 11 reaches a preset fertilization position. In this embodiment, when the vehicle body reaches the fertilization position, it is above the plant 60. Figure 7-Figure 13As shown, the fertilizing mechanism 40 includes a first fertilizer box 41, a second fertilizer box 42 and a soil turning mechanism 50. The first fertilizer box 41 is connected to the vehicle body 11 through an elastic connecting piece 412, and the second fertilizer box 42 is rotatably connected to the first fertilizer box 41. The soil turning mechanism 50 is hingedly installed at the bottom of the second fertilizer box 42, and a hydraulic rod 416 for adjusting the rotation of the soil turning mechanism 50 is provided at the bottom of the second fertilizer box 42. A rotating assembly for controlling the rotation of the second fertilizer box 42 is provided on the first fertilizer box 41. When the rotating assembly controls the rotation of the second fertilizer box 42, the second fertilizer box 42 drives the soil turning mechanism 50 to rotate, so that the soil turning mechanism 50 digs a fertilizer pit in the soil 70 around the plant 60, that is, Fig.13 As shown, it should be noted that the fast-penetrating agricultural fertilizer fertilization device disclosed in this embodiment is mainly used for fertilization after sowing or during the seedling stage of plants;

[0033] Furthermore, in the embodiment of the present application, the soil turning mechanism 50 includes a frame 51, a soil turning roller 52, a fixed shaft 526 and a rotating shaft 527. A plurality of partition frames 53 are fixedly installed at the bottom of the frame 51. A soil turning roller 52 is arranged between the partition frames 53 and the frame 51 and between two adjacent partition frames 53. The soil turning roller 52 includes an outer roller body 521 and an inner roller body 524 arranged inside the outer roller body 521. The outer wall of the inner roller body 524 fits the inner wall of the outer roller body 521. A soil turning blade 522 is installed on the surface of the outer roller body 521. The inner roller body 524 is rotatably connected to the outer roller body 521. The rotating shaft 527 is fixedly connected to the outer roller body 521, and the rotating shaft 527 is rotatably connected to the frame 51 and the partition frames 53. It can be understood that when the rotating shaft 527 is in a rotating state, When the outer roller 521 is in the rotating state, the outer roller body 521 rotates with the rotating shaft 527. During this process, the outer roller body 521 digs a fertilizer pit in the soil 70 around the plant 60; the rotating shaft 527 is a hollow shaft structure, and the fixed shaft 526 is arranged inside the rotating shaft 527. One end of the fixed shaft 526 is fixedly connected to the right end of the frame 51, and the fixed shaft 526 is also fixedly connected to the inner roller body 524. It can be understood that when the outer roller body 521 is in the rotating state, the fixed shaft 526 and the inner roller body 524 are in a fixed state; a plurality of first liquid outlets 523 are provided on the side wall of the outer roller body 521, and a plurality of second liquid outlets 525 cooperating with the first liquid outlets 523 are provided at the bottom of the inner roller body 524. A plurality of liquid supply ports are provided on the shaft section of the fixed shaft 526 located on the inner roller body 524. Fig.12As can be seen in the figure, the inner roller body 524 is a hollow structure. When fertilizer flows into the fixed shaft 526, the fertilizer enters the inner roller body 524 from the liquid supply port. During the rotation of the outer roller body 521, when the first liquid outlet 523 of the outer roller body 521 is connected with the second liquid outlet 525 of the inner roller body 524, the fertilizer inside the inner roller body 524 flows out through the second liquid outlet 525 and the first liquid outlet 523 in sequence, so as to realize fertilization during the soil turning process, and keep the fertilizer in a downward outflow state during the fertilization process, so that all the fertilizer flows to the fertilization pit, avoiding the phenomenon of fertilizer waste during the fertilization process;

[0034] Furthermore, in the embodiment of the present application, a rotating motor 54 and a third gear box 55 are installed on the frame 51, and a first bevel gear 551 and a second bevel gear 552 are arranged inside the third gear box 55. The output end of the rotating motor 54 extends into the third gear box 55 and is fixedly connected to the first bevel gear 551. One end of the rotating shaft 527 extends into the third gear box 55 and is fixedly connected to the second bevel gear 552. The first bevel gear 551 and the second bevel gear 552 are meshed. The rotating motor 54 is meshed with the first bevel gear 551 and the second bevel gear 552. The bevel gear 552 drives the rotating shaft 527 to rotate; in addition, in the embodiment of the present application, the other end of the fixed shaft 526 passes through the end of the rotating shaft 527 and extends out, and the extended end of the fixed shaft 526 is used to connect a fertilizer pipe (not shown in the figure), and the fertilizer pipe is arranged at the bottom of the second fertilizer box 42, and the fertilizer pipe is connected to the second fertilizer box 42. It can be understood that the fertilizer supply mechanism 20 is used to provide fertilizer to the first fertilizer box 41, the first fertilizer box 41 is connected to the second fertilizer box 42, and the second fertilizer box 42 supplies fertilizer to the soil-turning roller 52 through the fertilizer pipe, thereby realizing the simultaneous turning of soil and fertilizing.

[0035] In order to improve the fertilization efficiency and make the fertilizer penetrate into the soil 70 faster, a groove is provided at the bottom of the partition frame 53. When the second fertilizer box 42 drives the soil turning mechanism 50 to rotate, the soil turning mechanism 50 digs a fertilizer pit in the soil 70 around the plant 60. Fig.13As shown, since the tilling mechanism 50 is in an inclined state during the tilling process, the side of the fertilizer pit facing the plant 60 is an inclined surface. During the tilling process, the groove at the bottom of the partition frame 53 is formed on the inclined surface with multiple protrusions. The multiple protrusions are distributed in a stepped manner. Between two adjacent protrusions is a fertilization area 71. The fertilization area 71 is an annular trough structure. When the fertilizer is discharged by the tilling roller 52, it is retained inside each fertilization area 71, and the soil 70 is divided into multiple layers from top to bottom. The fertilizer inside each fertilization area 71 can quickly reach each layer of the soil 70 within the same leakage time, thereby improving the fertilizer penetration efficiency and the fertilizer absorption efficiency of the root system of the plant 60. In addition, compared with the fertilization method in the prior art, by opening multiple fertilization areas 71 in the soil 70, the fertilization uniformity can also be improved, avoiding the problem that the fertilizer concentration in the upper layer of the soil is too high to damage the root system of the plant 60 and the fertilizer concentration in the lower layer of the soil is too low to meet the fertilization requirements.

[0036] Please refer again Figure 7-8 In the embodiment of the present application, the rotating assembly includes a rotating motor 414 fixedly mounted on the first fertilizer box 41, a driving gear 415 fixedly connected to the output end of the rotating motor 414, and a ring gear 422 fixedly connected to the second fertilizer box 42, the driving gear 415 is meshed with the ring gear 422, and when the rotating motor 414 controls the driving gear 415 to rotate, the driving gear 415 drives the ring gear 422 and the second fertilizer box 42 to rotate; in addition, a protective cover 421 is also installed on the second fertilizer box 42, the upper end of the hydraulic rod 416 is connected to the protective cover 421, the lower end of the hydraulic rod 416 is hinged to the frame 51, and the hydraulic rod 416 is used to adjust the rotation angle of the frame 51, so that the fertilizer vehicle 10 retracts the soil turning mechanism 50 when driving and puts down the soil turning mechanism 50 when the fertilizer vehicle 10 reaches the preset fertilization position, so that the soil turning mechanism 50 is inserted into the soil 70.

[0037] See also Figure 1-Figure 6The side of the vehicle body 11 is installed with a connecting frame 12, the bottom of the connecting frame 12 is fixedly installed with a mounting frame 14, and the wheel 15 is rotatably installed on the mounting frame 14; the fertilizer supply mechanism 20 includes a base 21 and a fertilizer box 22, a guide rail 13 is fixedly installed on the vehicle body 11, a slider 131 is slidably installed inside the guide rail 13, one side of the slider 131 is connected to the guide rail 13 through a return spring 132, the base 21 is fixedly connected to the slider 131, and a sliding connection seat 215 is fixedly installed at the bottom of the base 21, and a second rack 211 is installed at the bottom of the sliding connection seat 215, and a drive shaft 2 is rotatably installed at the bottom of the vehicle body 11 13. A sector gear 212 is fixedly mounted on the driving shaft 213, and the sector gear 212 is meshed with the second rack 211. When the driving shaft 213 is in a rotating state, the sector gear 212 intermittently contacts the second rack 211, thereby driving the base 21 to slide along the guide rail 13. When the base 21 slides away from the center of the vehicle body 11, the return spring 132 is in a stretched state. When the sector gear 212 is separated from the second rack 211, the return spring 132 is reset and drives the base 21 to slide toward the center of the vehicle body 11. This reciprocating process causes the fertilizer box 22 to move continuously, thereby shaking the fertilizer inside the fertilizer box 22 to prevent the fertilizer from sinking to the bottom or clumping.

[0038] Furthermore, in the embodiment of the present application, the drive shaft 213 is connected to the rotating shaft of the wheel 15 through a transmission mechanism. When the fertilizer spreading vehicle 10 is in a driving state, the rotating shaft of the wheel 15 drives the drive shaft 213 to rotate through the transmission mechanism, thereby driving the base 21 and the fertilizer box 22 to move continuously; in addition, a stirring shaft 222 is rotatably installed inside the fertilizer box 22, and a plurality of stirring blades are arranged on the stirring shaft 222. The lower end of the stirring shaft 222 passes through the base 21 and is fixedly installed with a connecting gear 224. The first rack 111 is fixedly installed on the vehicle body 11, as shown in FIG. Figure 4 As shown, the first rack 111 is meshed with the connecting gear 224. During the reciprocating movement of the base 21 and the fertilizer box 22, the first rack 111 drives the connecting gear 224 to rotate, thereby driving the stirring shaft 222 to rotate, so that the stirring shaft 222 further stirs the fertilizer inside the fertilizer box 22 through the stirring blades.

[0039] It should be noted that the fertilizer box 22 is provided with a feed port 221, and the feed port 221 is used to add fertilizer. In the present embodiment, the fertilizer is liquid fertilizer. A liquid pump 225 is installed inside the fertilizer box 22. The liquid inlet end of the liquid pump 225 is connected to the fertilizer cavity inside the fertilizer box 22, and the liquid discharge end of the liquid pump 225 is connected to the feed pipe 30. The first fertilizer box 41 is provided with a liquid inlet 413, and the liquid inlet 413 is connected to the interior of the first fertilizer box 41. The liquid inlet 413 is also connected to the feed pipe 30. In the present embodiment, the feed pipe 30 is a hose structure, which is used to transport the fertilizer inside the fertilizer box 22 to the first fertilizer box 41. In addition, the fertilizer box 22 is also provided with a flushing port 223, which is used to flush and clean the interior of the fertilizer box 22. It should also be noted that, during the soil turning process, since the outer wall of the inner roller body 524 fits with the inner wall of the outer roller body 521, during the rotation of the outer roller body 521, when the first liquid outlet 523 and the second liquid outlet 525 are connected, the fertilizer inside the inner roller body 524 flows out through the second liquid outlet 525 and the first liquid outlet 523 in sequence. Since the fertilizer inside the inner roller body 524 is provided by the fertilizer pipe, and the fertilizer pipe is obtained by the fertilizer supply mechanism 20 by pumping (liquid pump 225), the fertilizer flows out of the second liquid outlet 525, The fertilizer at the first liquid outlet 523 has water pressure, which can impact the soil, thereby preventing the soil from clogging the second liquid outlet 525 and the first liquid outlet 523 during the soil turning process. In addition, when the first liquid outlet 523 and the second liquid outlet 525 are not connected, the outer wall of the inner roller body 524 blocks the first liquid outlet 523. Even if a small amount of soil is retained inside the first liquid outlet 523, when the first liquid outlet 523 and the second liquid outlet 525 are connected again, the soil retained inside the first liquid outlet 523 is dispersed under the action of the fertilizer water pressure.

[0040] See also Figure 1 as well as Figure 7 In the embodiment of the present application, an extrusion block 411 is installed on the top of the first fertilizer box 41, and the upper end of the extrusion block 411 has an extrusion slope. A through hole with the same shape as the extrusion block 411 is opened on the vehicle body 11. During the driving process of the fertilizer spreading vehicle 10, the extrusion slope of the upper end of the extrusion block 411 is exposed to the through hole. Figure 1As shown, at this time, the fertilizer supply mechanism 20 reciprocates in the area between the extrusion block 411 and the connecting frame 12 on the vehicle body 11. When the fertilizer vehicle 10 stops driving, the sector gear 212 disengages from the second rack 211, and the reset spring 132 drives the fertilizer supply mechanism 20 to reset. The fertilizer supply mechanism 20 moves toward the center of the vehicle body 11, that is, the position of the extrusion block 411. After the reset is completed, the fertilizer supply mechanism 20 presses the extrusion block 411 downward through the extrusion slope, so that the extrusion block 411 drives the first fertilizer box 41 to move downward, thereby lowering the height of the fertilizer mechanism 40. It should be noted that the purpose of lowering the fertilizer mechanism 40 is to facilitate the soil turning mechanism 50 to turn the soil 70. During the driving process of the fertilizer vehicle 10, in order to prevent the fertilizer mechanism 40 from touching the debris on the surface of the soil 70, the fertilizer mechanism 40 needs to be raised. It should also be noted that in the initial state, that is, when the vehicle body 11 is stationary, the fertilizer feeding mechanism 20 is located at the center of the vehicle body 11. After the vehicle body 11 starts to move, the fan gear 212 intermittently contacts the second rack 211. In order to prevent the second rack 211 from driving the fertilizer feeding mechanism 20 back to the center of the vehicle body 11, the rotation speed of the fan gear 212 can be adjusted so that the fan gear 212 contacts and meshes with the second rack 211 again before the second rack 211 is completely reset. The technical solution for adjusting the rotation speed of the fan gear 212 can adopt the existing technology, which will not be elaborated in this embodiment.

[0041] In the embodiment of the present application, since two fertilizer feeding mechanisms 20 are symmetrically arranged on both sides of the vehicle body 11, in order to drive the two fertilizer feeding mechanisms 20 to move, the corresponding transmission mechanism includes a first gear box 151 and a second gear box 153, and the first gear box 151 and the second gear box 153 are both equipped with a drive motor 152, and the drive motor 152 is connected to the input shaft of the first gear box 151 or the second gear box 153, and the first gear box 151 and the second gear box 153 both have a first output shaft and a second output shaft, wherein the first output shaft of the first gear box 151 is connected to the rotating shaft of the left wheel 15, and the second output shaft of the first gear box 151 is connected to the rotating shaft of the left wheel 15, and the second output shaft of the first gear box 151 is connected to the rotating shaft of the left wheel 15 through the synchronous belt 214. The first output shaft of the second gear box 153 is connected to the rotating shaft of the right wheel 15, and the second output shaft of the second gear box 153 is connected to the driving shaft 213 on the same side through a synchronous belt 214. The second output shaft of the first gear box 151 and the second output shaft of the second gear box 153 rotate in opposite directions, so that the driving shaft 213 on the left and the driving shaft 213 on the right are opposite in direction. In this embodiment, the driving shaft 213 on the left rotates counterclockwise and the driving shaft 213 on the right rotates clockwise, thereby driving the fertilizer feeding mechanisms 20 on both sides to move toward the center of the vehicle body 11 and away from the center of the vehicle body 11 at the same time.
