Description

Technical Field

[0001] The present application belongs to the field of vegetable fertilization, and specifically relates to a vegetable root fertilizer applicator. Technical Background

[0002] In the prior art, there is a Chinese application with application number CN201911105986.8 and the patent name is an orchard water and fertilizer integrated high-efficiency hole applicator.

[0003] The application relates to an orchard water and fertilizer integrated high-efficiency hole-applying machine, which belongs to the technical field of agricultural machinery. The application includes a crawler walking device, a frame, a power supply, an engine, a gearbox, a control device, a four-bar mechanism, a variable fertilizer discharge device, a variable drainage device, a covering plate, a walking wheel, a pit digging device, and a hydraulic device.

[0004] This application mainly solves the problem that there is a lack of efficient and reliable integrated water and fertilizer hole-applying machines on the market, which have single functions and low mechanization levels, insufficient control over the precision of water and fertilizer application, and cannot achieve continuous operation in orchard management, and fail to effectively reduce the work pressure of fruit farmers. In the continuous forward process, it can complete the synchronous operations of digging pits, discharging fertilizers, applying water, and covering the soil for integrated water and fertilizer hole-applying in orchards, and can adjust the amount of water and fertilizer applied according to agronomic requirements to ensure that all water and fertilizer enter the pit, thus achieving efficient management of integrated water and fertilizer hole-applying in orchards. This application strictly complies with the design requirements of agricultural machinery, and has a relatively simple structure and is easy to use.

[0005] However, the above application still has the following problems:

[0006] After the trenching device digs the pit, the fertilizer is discharged into the pit by aligning the fertilizer discharge components (variable fertilizer discharge device, variable drainage device and hydraulic device) with the preset pit position. However, the environment in which agricultural machinery operates in the field is complex and the terrain is not in an ideal shape. When the agricultural machinery is traveling on the rugged road in the field, the fuselage will shake, resulting in the direction of the pit dug by the trenching device not being the preset pit position and direction, and the fertilizer discharge components arranged on the rear side of the trenching device can only be aligned with the preset pit position and direction. This results in the fertilizer discharge components of the agricultural machinery of the above application being unable to accurately spray water and fertilizer into the actually dug fertilization pit, and cannot ensure that all the sprayed water and fertilizer enter the pit. Therefore, in fact, there is still a technical problem of some water and fertilizer being sprayed outside the fertilization pit, and there is still a waste of water and fertilizer. Summary of the invention

[0007] The purpose of this application is to address the technical problem that in the prior art, part of the water and fertilizer is actually sprayed outside the fertilization pit, resulting in a waste of water and fertilizer.

[0035] Please refer to Figures 1 to 7 In a specific embodiment of the present application, Figure 1 As shown, there is a vegetable root fertilizer applicator, comprising:

[0036] A walking frame 100, the walking frame 100 has two layers, the lower frame is provided with a walking mechanism, such as tires, crawlers or any walking mechanism in the prior art, and the upper frame is higher than the lower frame;

[0037] A fertilizer box 200, wherein the fertilizer box 200 is arranged on the traveling frame 100. As mentioned above, the fertilizer box 200 is arranged on the upper shelf of the traveling frame 100, that is, the height of the fertilizer box 200 is higher than the lower shelf;

[0038] The adjustable mounting frame 300 is slidably arranged on the walking frame 100. As described above, specifically, the adjustable mounting frame 300 is arranged on the lower frame of the walking frame 100, and the height of the fertilizer box 200 is higher than the lower frame, that is, the height of the fertilizer box 200 is higher than the adjustable mounting frame 300, and the adjustable mounting frame 300 can slide in the horizontal direction. The walking frame 100 is provided with a sliding frame that enables the adjustable mounting frame 300 to slide in the horizontal direction. In a specific embodiment, the lower frame is provided with a sliding frame parallel to the forward direction along the forward direction of the fertilizing device of the present application, and the sliding frame is a linear frame. The adjustable mounting frame 300 can slide straight forward and backward along the forward direction on the linear sliding frame, that is, the adjustable mounting frame 300 can adjust its position forward and backward on the walking frame 100 along the forward direction of the fertilizing device of the present application;

[0039] A trenching assembly 400, wherein the trenching assembly 400 is arranged on the adjustable mounting frame 300, and can slide forward and backward along a straight line on the linear sliding frame along the advancing direction along with the adjustable mounting frame 300, and the trenching assembly 400 can rotate downward along an arc (and is hinged with the adjustable mounting frame 300), and the trenching assembly 400 can be a mechanical gripper, and the soil on the surface of the land is grabbed by the mechanical gripper along the arc to form a pit on the surface of the land, and the dug pit is the fertilizer pit. The trenching assembly 400 can also be any device or mechanism in the prior art before the filing date of this application that can dig a fertilizer pit on the surface of the land along an arc track;

[0040] In a preferred embodiment, considering the cost problem, the trenching assembly 400 includes a trenching member 410 and a driving member 420, wherein the middle portion of the trenching member 410 is hinged to the adjustable mounting frame 300, and the driving member 420 is disposed on the adjustable mounting frame 300 and is drivingly connected to the upper end of the trenching member 410, and the driving member 420 drives the upper end of the trenching member 410 to rotate around the hinge point, so that the lower end of the trenching member 410 moves along an arc and digs a fertilizer discharge pit in the soil; and

[0041] A fertilizer spraying assembly 500 is connected to the fertilizer box 200, and the fertilizer spraying assembly 500 is arranged on the back side of the trenching member 410 and connected to the trenching member 410. The fertilizer spraying assembly 500 sprays fertilizer into the fertilizer discharge pit after the trenching member 410 digs the fertilizer discharge pit. In the process of the trenching component 400 digging a fertilizer pit on the land surface along the arc, its arc trajectory has a starting end and an ending end, that is, the trenching component 400 can dig a fertilizer pit on the land surface along the arc from the starting end to the ending end, and the fertilizer spraying component 500 is arranged on one side of the trenching component 400 (the fertilizer spraying component 500 is arranged on the side of the trenching component 400 close to the starting end) and is connected to the trenching member 410. The fertilizer spraying component 500 is connected to the trenching component 400 on the side close to the starting end. In this way, when the trenching component 400 digs a fertilizer pit on the land surface along the arc, the dug fertilizer pit is located between the vertical line from the starting end to the soil surface and the vertical line from the ending end to the soil surface. When the trenching assembly 400 moves to the terminal end, the fertilizer spraying assembly 500 moves with the trenching assembly 400 to a position some distance away from the terminal end, and the position is aligned with the fertilizer pits located at the starting end and the terminal end. The fertilizer spraying assembly 500 can be any device connected to the fertilizer box 200 that can spray water and fertilizer into the fertilizer pit. Regardless of which device the fertilizer spraying assembly 500 is, the water and fertilizer in the fertilizer box 200 can be better sprayed into the fertilization pit under the action of gravity (because the height of the fertilizer box 200 is higher than the trenching fertilizer discharge unit, that is, the height of the fertilizer box 200 is higher than the fertilizer spraying assembly 500, so the water and fertilizer can be better sprayed by the fertilizer spraying assembly 500 under the action of gravitational potential energy).

[0042] As mentioned above, a specific implementation process of the vegetable root fertilizer spreader is as follows:

[0043] The vegetable root fertilizer spreader rides on the vegetable ridges (that is, the walking frame 100 is on the ridges, and the walking mechanism of the walking frame 100 is located at the ridge furrows between the ridges), advances along the ridges, and advances to the area to be fertilized where fertilizer is needed. The vegetable root fertilizer spreader stops advancing in the area to be fertilized for a period of time. During this period, the trenching assembly 400 performs trenching operations on both sides of the ridges in the area to be fertilized. In the first case, while digging fertilizer pits on both sides of the ridges in the area to be fertilized, the fertilizer spraying assembly 500 and the trenching assembly 400 are linked in the prior art, for example, the linkage technology of a liquid pump type manual sprayer. In this application, the following implementation is performed: a structure of a liquid pump type manual sprayer is added to the adjustable mounting frame 300, and one end of the rocker arm is hinged to the adjustable mounting frame 300. The other end of the rocker is hinged to the upper end of the trenching member 410. When working, the upper end of the trenching member 410 movably shakes the rocker, and through the action of the connecting rod mechanism, the plug rod is made to reciprocate in the pump barrel.

[0044] When the plug rod moves upward (when the trenching member 410 returns to its original position after trenching), the leather cup moves upward from the lower end, and a partial vacuum is formed under the leather cup due to the increasing volume of the cavity formed by the leather cup and the pump barrel. At this time, the water and fertilizer in the water and fertilizer tank 200, under the pressure difference between the liquid surface and the cavity, opens the water inlet ball valve and enters the pump barrel along the water inlet pipeline, completing the water absorption process.

[0045] When the leather cup moves downward from the upper end (when the trenching member 410 performs trenching), the water and fertilizer in the pump barrel begin to be squeezed, causing the water and fertilizer pressure to increase suddenly, the water inlet valve is closed, the water outlet valve is pressed open, and the water and fertilizer enter the air chamber through the water outlet valve. The air in the air chamber is compressed, generating pressure (up to 800kPa) on the water and fertilizer, and the air chamber has the function of stabilizing the pressure. After turning on the switch, the water and fertilizer are sprayed out through the nozzle. ) In the second case, fertilizer is sprayed at the same time; in the second case, after the fertilizer pits are dug on both sides of the ridge of the area to be fertilized, the fertilizer spraying assembly 500 is opened by a separate control method. No matter which of the above methods is used, the fertilizer spraying assembly 500 will move along the arc with the trenching assembly 400, so as to align with the dug fertilizer pit, and the water and fertilizer can be accurately sprayed into the fertilizer pit by the fertilizer spraying assembly 500 under the action of gravitational potential energy. Then the vegetable root fertilizer spreader continues to ride on the vegetable ridges (that is, the traveling frame 100 is on the ridges, and the traveling mechanism of the traveling frame 100 is located at the furrows between the ridges), moves along the ridges to the next area to be fertilized, and repeats the above operation.

[0046] Preferably, a pressure pump is provided between the fertilizer box 200 and the fertilizer spraying assembly 500. When the water fertilizer cannot be sprayed into the fertilizer pit smoothly due to special circumstances (blockage, component deformation and other emergencies), the pressure pump can pressurize the water fertilizer and spray it into the fertilizer pit smoothly.

[0047] As described above, the beneficial effects of the vegetable root fertilizer applicator are as follows: fertilizer pits are dug along the arc on both sides of the vegetable ridge by the trenching component 400, and the fertilizer spraying component 500 can be aligned with the actually dug fertilizer pits along the arc along the trenching component 400, and then the fertilizer spraying component 500 sprays water and fertilizer into the fertilizer pits, so that the water and fertilizer in the fertilizer pits penetrate into the roots of the vegetables (the vegetables are planted on the ridges, and the water and fertilizer infiltrate into the ridges in the fertilizer pits, which means they penetrate into the roots of the vegetables), thereby preventing the water and fertilizer from flowing from the soil surface to the vegetables. The problem of areas that cannot be absorbed and utilized is solved, and water and fertilizer are prevented from flowing on the soil surface and causing waste of water and fertilizer. The fertilizer spraying component 500 can be aligned with the actual dug fertilizer pit along the arc along the trenching component 400, avoiding the problem in the prior art that in complex field operations, the fertilizer pit is not dug at the preset position, resulting in some water and fertilizer being unable to be sprayed into the fertilizer pit. By aiming the fertilizer spraying component 500 at the dug fertilizer pit for spraying fertilizer, the technical effect of accurately spraying water and fertilizer into the fertilizer pit and saving water and fertilizer is thoroughly achieved.

[0048] As mentioned above, melons and vegetables include watermelons, cucumbers, wild rice melons and other fruits and vegetables. The amount of fertilizer and the depth of fertilizer required for each melon and vegetable are different, so it is necessary to open fertilizer pits of different sizes and depths in the melon field. In a possible embodiment, the trenching member 410 includes a main rod 411 and a trenching triangle plate 412. The main rod 411 is hinged to the adjustable mounting frame 300, and one end of the main rod 411 is connected to the driving member 420. One end of the main trunk is driven by the driving member 420 to rotate around the intersection hinge point. The trenching triangle plate 412 is arranged at the other end of the main rod 411. When one end of the main trunk is driven by the driving member 420 to rotate around the intersection hinge point, the trenching triangle plate 412 at the other end will rotate along the arc, thereby digging a fertilizer pit in the melon field. The trenching triangle plate 412 of different shapes and sizes can be replaced according to the different varieties of melons and vegetables, so that when the trenching triangle plate 412 at the other end rotates along the arc, fertilizer pits of different shapes and sizes are dug. Beneficial effects: The trenching triangle plates 412 of different shapes and sizes can be replaced according to different varieties of melons and vegetables, so that the trenching triangle plate 412 at the other end can be rotated along the arc to dig fertilizer pits of different shapes and sizes.

[0049] As described above, the fertilizer spraying assembly 500 is arranged on one side of the trenching member 410, that is, the fertilizer spraying assembly 500 is directly installed on the main rod 411. It takes multiple experimental attempts to install the fertilizer spraying assembly 500 at different positions of the main rod 411 to determine that the fertilizer spraying direction of the fertilizer spraying assembly 500 can be aligned with the dug fertilizer pit. In a possible embodiment, the fertilizer spraying assembly 500 includes a mounting plate 510, a nozzle 520 and a fertilizer pipe 530. The mounting plate 510 is arranged on the back side of the main rod 411. The mounting plate 510 is a flat plate-shaped plate that can be positioned and aligned with the fertilizer pit when the fertilizer spraying assembly 500 is installed thereon, and is close to the trenching triangle plate 412. Being close to the trenching triangle plate 412 can make the mounting plate 510 better play the above-mentioned positioning role. The nozzle 520 is installed on the mounting plate 510. As described above, it can be aligned with the fertilizer pit while the fertilizer pit is dug out by the other end of the trenching member 410. One end of the fertilizer pipe 530 is connected to the fertilizer box 200, and the other end is connected to the nozzle 520. Beneficial effect: By determining the installation position of the nozzle 520 through the installation plate 510, the alignment angle of the nozzle 520 can be quickly and efficiently positioned, so that when the vegetable root fertilizer spreader is used and maintained, the nozzle 520 can be directly installed on the installation plate 510, making the installation and maintenance of the nozzle 520 more efficient and quick.

[0050] Further, the nozzle 520 is an electric nozzle 520, and is connected to the driving member 420 by electrical signals. When the driving member 420 drives the trenching member 410 to rotate and dig out a fertilizer pit without retracting it, the electric nozzle 520 is installed on one side of the trenching member 410 so that it is just aimed at the dug fertilizer pit. At this time, the electric nozzle 520 senses the action of the driving member 420 driving the trenching member 410 to rotate and dig out the fertilizer pit, and sends a signal to the electric nozzle 520. The electric nozzle 520 receives the signal and sprays water and fertilizer into the dug fertilizer pit. The beneficial effect is that the electric nozzle 520 can avoid unreliable mechanical structures and directly respond by sensing the state of the driving member 420 driving the trenching member 410. When the driving member 420 drives the trenching member 410 to rotate around the hinge point to dig out the fertilizer pit without retracting it, the electric nozzle 520 is just aimed at the dug fertilizer pit. The electric nozzle 520 responds to the signal sent by the driving member 420, and the sprayed water and fertilizer are accurately sprayed into the dug fertilizer pit.

[0051] Furthermore, the number of the adjustable mounting frames 300 is an even number. The beneficial effect is that the trenching assembly 400 and the fertilizer spraying assembly 500 as described above are all arranged on the multiple adjustable mounting frames 300, so that an even number of fertilizer pits can be dug in the melon field at the same time, which significantly increases the efficiency of the melon and vegetable root fertilizer spreader in the field.

[0052] As mentioned above, melons and vegetables include watermelon, cucumber, wild rice squash and other fruits and vegetables. Most of the melons and vegetables are planted in ridges. If trenching and fertilization are only performed on one side of the ridge, the water and fertilizer required for the area will be applied on one side of the ridge. This will cause the roots of the vegetables on that side to be burned by excessive water and fertilizer, while the other side will be malnourished due to lack of water and fertilizer, resulting in root deformities of the vegetables. In a possible embodiment, an even number of the adjustable mounting frames 300 are divided into two rows, and the number of the two rows of the adjustable mounting frames 300 is equal. The two rows of the adjustable mounting frames 300 are parallel to each other and distributed on both sides of the walking frame 100. Beneficial effect: When the vegetable root fertilizer spreader is applying fertilizer in the field, the vegetable root fertilizer spreader rides on the vegetable ridge, and two rows of adjustable mounting frames 300 are respectively located on both sides of the vegetable ridge, and trenches are dug and fertilized on both sides of the vegetable ridge, and the water and fertilizer required for the corresponding area are divided into two parts, which are applied on both sides of the vegetable ridge respectively, to avoid the vegetable roots on one side being burned by excessive water and fertilizer, and the other side being malnourished due to lack of water and fertilizer, thereby avoiding the problem of vegetable root deformities.

[0053] As mentioned above, melons and vegetables include watermelons, cucumbers, wild rice melons and other fruits and vegetables. Different melons and vegetables require different amounts of fertilizer. In a possible embodiment, a detachable sleeve 310 is provided on the lower side of the adjustable mounting frame 300. The detachable sleeve 310 can be slidably engaged with the walking frame 100. The detachable sleeve 310 is sleeved on the sliding frame as described above, so that the adjustable mounting frame 300 can adjust the distance between the adjustable mounting frames 300 on the walking frame 100. By adjusting the distance between the adjustable mounting frames 300, the effect of adjusting the fertilization density (the number of fertilizer pits dug and fertilizer sprayed per unit area of ​​land) can be achieved. Beneficial effect: By adjusting the distance between the adjustable mounting frames 300, different amounts of fertilizer required to adapt to different melons and vegetables can be achieved.

[0054] As described above, when the vegetable root fertilizer spreader is performing trenching and fertilizing operations in the vegetable field, the vibration generated by the rotation of the trenching member 410 around the hinge point and the vibration generated by the movement of the vegetable root fertilizer spreader may cause the sliding sleeve on the sliding frame of the walking frame 100 to be displaced by the vibration and deviate from the pre-adjusted position, causing the fertilization density (the number of fertilization pits dug and fertilizer sprayed per unit area of ​​land) to exceed or be less than the predetermined fertilization density (the number of fertilization pits dug and fertilizer sprayed per unit area of ​​land). A fixing hole 311 is provided on the detachable sliding sleeve 310, and a fastener 312 is provided in the fixing hole 311. After the adjustable mounting frame 300 is adjusted to slide to the position corresponding to the fertilization density of the vegetable type (the number of fertilizer pits dug and fertilizer sprayed per unit area), the detachable sleeve 310 can be fixed at this position by the fastener 312, thereby achieving the following beneficial effects: when the vegetable root fertilizer spreader is performing trenching and fertilizing operations in the vegetable field, the vibration generated by the rotation of the trenching member 410 around the hinge point and the vibration generated by the movement of the vegetable root fertilizer spreader are avoided, causing the sleeve to be displaced on the sliding frame of the walking frame 100 due to the vibration, avoiding the adjustable mounting frame 300 from being separated from the pre-adjusted position, and avoiding the fertilization density (the number of fertilizer pits dug and fertilizer sprayed per unit area) exceeding or being less than the predetermined fertilization density (the number of fertilizer pits dug and fertilizer sprayed per unit area).

[0055] Furthermore, the adjustable mounting frame 300 is provided with a pitch-adjusting screw 320, and two adjacent adjustable mounting frames 300 in each row are connected by the pitch-adjusting screw 320. Beneficial effect: The pitch-adjusting screw 320 can adjust the distance between two adjacent adjustable mounting frames 300, and a finer distance can be adjusted by the pitch-adjusting screw 320 than directly sliding the adjustable mounting frame 300 on the walking frame 100 by the staff.

[0056] Furthermore, the traveling frame 100 is provided with elevated traveling wheels 110, and the height of the traveling frame 100 from the ground is at least 50 cm. The beneficial effect is that the height of the traveling frame 100 from the ground is at least 50 cm, so that when the vegetable root fertilizer spreader is operating in the field, the traveling frame 100 is prevented from colliding with the vegetable ridges and the vegetables on the vegetable ridges.

[0057] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation methods of the present application. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
