DETAILED DESCRIPTION

[0022] Embodiment 1

[0023] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it can be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application.

[0026] like Figure 1 As shown, an embodiment of the present application provides a stepless fertilizer amount adjustment quantitative fertilization device, which includes a frame 1, a traveling structure 2, a counting structure 3, a fertilizer box 4, a stepless fertilizer storage structure 5 and a fertilization drive structure 6.

[0027] Among them, the traveling structure 2, the counting structure 3, the fertilizer box 4, the stepless fertilizer storage structure 5 and the fertilization drive structure 6 are all arranged on the frame 1, and the structure of the frame 1 can be set based on technical personnel in this field to install the traveling structure 2, the counting structure 3, the fertilizer box 4, the stepless fertilizer storage structure 5 and the fertilization drive structure 6.

[0028] Exemplarily, the traveling structure 2 is arranged at the front end of the traveling direction on the frame 1 inside the fertilizing device, the counting structure 3 is connected to the traveling structure 2, and the fertilizer box 4, the stepless fertilizer storage structure 5 and the fertilizer driving structure 6 are arranged at the rear end of the traveling direction on the frame 1 inside the fertilizing device.

[0029] The traveling structure 2 is used to drive the stepless fertilizer amount adjustment quantitative fertilization device to move. Figure 2As shown, the traveling structure 2 includes ground wheels for rotating and traveling in the field and avoiding slipping.

[0030] Optionally, the traveling structure 2 may include four ground wheels, which are arranged on both sides of the frame 1, and are driven by a power device or manual drive to drive the stepless fertilizer amount adjustment quantitative fertilization device to move.

[0031] In one embodiment, the counting structure 3 is connected to the traveling structure 2, and the traveling distance is counted when the traveling structure 2 is traveling, and counting information is obtained. The counting information includes the distance traveled by the traveling structure 2. Fertilization control is performed according to the counting information, which can ensure that fertilization is performed at a uniform traveling distance and the uniformity of the fertilization intervals.

[0032] In one embodiment, the counting structure 3 further includes a counting wheel 31, a magnetic component 32 and a sensor 33. The counting wheel 31 is connected to the ground wheel in the traveling structure 2 and rotates together with the ground wheel when traveling. Exemplarily, the rotation ratio of the counting wheel 31 to the ground wheel in the traveling structure 2 is 1:1, that is, when the ground wheel rotates one circle, the counting wheel 31 also rotates one circle.

[0033] The magnetic component 32 is arranged on the counting wheel 31, and moves in a circular motion with the counting wheel 31. The sensor 33 is arranged on the side of the frame 1 close to the counting wheel 31. When the magnetic component 32 moves close to the sensor 33 with the counting wheel 31, a magnetic field effect can be generated, and the sensor 33 can count and generate counting information. Specifically, the counting information includes the number of revolutions of the counting wheel 31, that is, the number of revolutions of the ground wheel. In this way, the distance traveled by the traveling structure 2 can be counted and obtained.

[0034] Optionally, the distance traveled by the traveling structure 2 may be obtained by positioning and counting to obtain the counting information.

[0035] Preferably, the sensor 33 is a Hall sensor.

[0036] The fertilizer box 4 is fixed on the frame 1, and fertilizer is stored in the fertilizer box 4 for fertilization.

[0037] like Figure 3 and Figure 4 As shown, the stepless fertilizer storage structure 5 includes at least two stepless fertilizer storage devices 51. At each moment, the first end of one stepless fertilizer storage device 51 is connected to the fertilizer box 4 for supplementing fertilizer, and the second end of one stepless fertilizer storage device 51 is connected to the outside to spread the fertilizer by gravity for fertilization. The second end is the end opposite to the first end. The first end and the second end of the other stepless fertilizer storage devices 51 are both closed, waiting for supplementing fertilizer or fertilizing, and the capacity of each stepless fertilizer storage device 51 can be adjusted steplessly to improve the flexibility of controlling the amount of fertilizer applied.

[0038] In one embodiment, a fertilizer replenishing port 41 is provided on one side of the fertilizer box 4 connected to the stepless fertilizer storage structure 5. At each moment, at least one of the two stepless fertilizer storage devices 51 is connected to the fertilizer replenishing port 41, thereby connecting to the fertilizer box 4, so that the fertilizer enters the connected stepless fertilizer storage device 51 for fertilizer replenishment.

[0039] In one embodiment, the fertilizer box 4 is fixed to the frame 1 through the fertilizer box 4 height adjustment structure 12, and the height of the fertilizer box 4 height adjustment structure 12 is adjustable, so that the height of the fertilizer box 4 is adjustable. Exemplarily, fixed columns are provided on both sides of the frame 1, and sliders are provided on the fixed columns. The sliders can be fixed to the fixed columns by bolts or slide relative to the fixed columns. The two sliders are fixedly connected to the fertilizer box 4, so that the height of the fertilizer box 4 is adjusted.

[0040] like Figure 5 As shown, in one embodiment, the stepless fertilizer storage structure 5 includes a connecting disk 52, and the connecting disk 52 includes at least two connecting holes, which correspond one to one with the at least two stepless fertilizer storage devices 51 mentioned above. At least two stepless fertilizer storage devices 51 are fixed on the connecting disk 52 and are connected to the at least two connecting holes. At each moment, one of the at least two connecting holes is connected to the fertilizer replenishing port 41, so that one stepless fertilizer storage device 51 is connected to the fertilizer replenishing port 41.

[0041] like Figure 6 As shown, each of the at least two continuously variable fertilizer storages 51 includes a primary fertilizer storage 511 , a secondary fertilizer storage 512 , and a tertiary fertilizer storage 513 .

[0042] The primary fertilizer storage 511 is tubular and connected to the corresponding connection hole. The secondary fertilizer storage 512 is tubular and is sleeved in the primary fertilizer storage 511. It can move relative to the primary fertilizer storage 511 along the axis and cannot be separated. The tertiary fertilizer storage 513 is tubular and is sleeved in the secondary fertilizer storage 512. It can move relative to the secondary fertilizer storage 512 along the axis and cannot be separated. In this way, a stepped sleeve-shaped stepless fertilizer storage 51 is formed.

[0043] The primary fertilizer storage 511, the secondary fertilizer storage 512 and the tertiary fertilizer storage 513 are arranged in sequence in a direction away from the connecting disk 52, and their diameters decrease gradually.

[0044] Preferably, the primary fertilizer storage 511, the secondary fertilizer storage 512 and the tertiary fertilizer storage 513 are installed by interference fit.

[0045] When the amount of fertilizer needs to be adjusted, the secondary fertilizer storage device 512 and the tertiary fertilizer storage device 513 can be moved along the axis line so that the volume of the cavity formed by the primary fertilizer storage device 511, the secondary fertilizer storage device 512 and the tertiary fertilizer storage device 513 are connected in a sleeve manner, thereby changing the volume of the cavity and realizing stepless fertilizer amount adjustment.

[0046] When adjusting the amount of fertilizer, the height of the fertilizer box 4 can be adjusted through the height adjustment structure 12 of the fertilizer box 4, thereby adjusting the height of the first-level fertilizer storage 511 connected to the fertilizer box 4, and then adjusting the size of the internal volume of each stepless fertilizer storage.

[0047] In one embodiment, the connecting disk 52 in the stepless fertilizer storage structure 5 is connected to the fertilizer box 4 through a bearing, so that the stepless fertilizer storage structure 5 can rotate relative to the fertilizer box 4, so that different stepless fertilizer storage devices 51 are connected to the fertilizer replenishing port 41 through the connecting hole, and fertilizer is replenished to different level fertilizer storage devices.

[0048] In order to achieve fertilization at uniform intervals, the frame 1 also includes a fertilizer plate and a fertilizer outlet 11. The fertilizer plate is arranged at one end of the stepless fertilizer storage structure 5 away from the fertilizer box 4, that is, the lower end of the stepless fertilizer storage structure 5.

[0049] The fertilizer outlet 11 is arranged on the fertilizer application plate, and is connected to one of the at least two stepless fertilizer storages 51, specifically connected to the third-level fertilizer storage 513 in one of the stepless fertilizer storages 51, so that it is connected to the outside for fertilization. The axis of the fertilizer outlet 11 does not coincide with the axis of the fertilizer supplementation port 41, so that in at least two stepless fertilizer storages 51, the stepless fertilizer storage 51 whose first end is connected to the fertilizer supplementation port 41 and the stepless fertilizer storage 51 whose second section is connected to the fertilizer outlet 11 are not the same stepless fertilizer storage 51, so that one stepless fertilizer storage 51 is used for fertilization, and the other stepless fertilizer storage 51 is used for fertilization, and then the stepless fertilizer storage 51 is moved and the second end is connected to the fertilizer outlet 11 for fertilization after the first end of the stepless fertilizer storage 51 is connected to the fertilizer supplementation port 41 for fertilization.

[0050] In one embodiment, the fertilization driving structure 6 includes a motor 61, a motor driver 62, a driving pulley 63 and a driven pulley 64. The motor 61 is used to provide power to drive fertilization, and the motor driver 62 is connected to the counting structure 3 and the motor 61 to make a judgment based on the counting information and drive the motor 61.

[0051] The driving pulley 63 is connected to the motor 61 and rotates under the drive of the motor 61. The driven pulley 64 is connected to the driving pulley 63 and the stepless fertilizer storage structure 5, and is driven by the driving pulley 63 through a belt transmission, and rotates under the drive of the motor 61, and drives the stepless fertilizer storage structure 5 to rotate relative to the fertilizer box 4 through the bearing.

[0052] Exemplarily, the driven pulley 64 is connected to the stepless fertilizer storage structure 5 through a transmission shaft to drive the stepless fertilizer storage structure 5 to rotate and move. In addition to the fertilizer outlet 11, a through hole is provided on the fertilizing disc, and the transmission shaft passes through the through hole to connect the driven pulley 64 and the stepless fertilizer storage structure 5.

[0053] Through the above structure, when the counting information has not reached the counting threshold, the fertilization drive structure 6 is on standby, so that the stepless fertilizer storage structure 5 is in a static state. When the counting information reaches the counting threshold, the counting information is cleared, and the fertilization drive structure 6 is started to drive the stepless fertilizer storage structure 5 to move, so that the stepless fertilizer storage device 51 connected to the fertilizer box 4 and the outside is transformed to perform fertilization and fertilization.

[0054] Exemplarily, a program for determining whether the counting information reaches a counting threshold is set up through a circuit board in the prior art and embedded in the motor driver 62 .

[0055] In one embodiment, when the counting information does not reach the counting threshold, the motor driver 62 is in a standby state, wherein the stepless fertilizer storage 51 connected to the fertilizer outlet 11 scatters all the stored fertilizers, and when the counting information reaches the counting threshold, the motor driver 62 clears the counting information, the counting structure 3 counts again, and the motor driver 62 drives the motor 61 to work for a preset time, so that the stepless fertilizer storage structure 5 rotates a preset angle, and at least two stepless fertilizer storages 51 rotate a preset angle with the axis of the connecting disk 52 as the center of the circle, so that the stepless fertilizer storage 51 connected to the fertilizer replenishment port 41 and the fertilizer outlet 11 is changed. Among them, after the stepless fertilizer storage 51 connected to the fertilizer outlet 11 is changed, it is not connected to the fertilizer outlet 11, and after the stepless fertilizer storage 51 connected to the fertilizer replenishment port 41 is changed, the fertilizer replenishment is completed and it is not connected to the fertilizer replenishment port 41.

[0056] The preset time and the preset angle are set according to the number of the at least two stepless fertilizer storages 51 .

[0057] Preferably, the stepless fertilizer storage structure 5 includes four stepless fertilizer storages 51, and the preset angle is 90°. In this way, after the motor driver 62 drives the motor 61 to work, the stepless fertilizer storage 51 connected to the fertilizer outlet 11 moves to wait for fertilizer supplementation, and the stepless fertilizer storage 51 connected to the fertilizer supplementation port 41 moves to wait for fertilization, the stepless fertilizer storage 51 that has completed fertilization moves to connect with the fertilizer outlet 11 to fertilize, the stepless fertilizer storage 51 to be fertilized moves to connect with the fertilizer supplementation port 41 to fertilize, and the stepless fertilizer storage 51 to be fertilized moves to connect with the fertilizer outlet 11 to fertilize.

[0058] In this way, the amount of fertilizer can be adjusted steplessly, and fertilizer and supplementary fertilizer can be applied at uniform intervals.

[0059] In one embodiment, those skilled in the art can set the counting threshold according to their needs, for example, according to the distance interval of crop fertilization, for example, the counting threshold can be 2 circles, or 0.5m, etc. In this way, stepless fertilization interval adjustment can be achieved.

[0060] The embodiment of the present application provides a quantitative fertilization device with stepless fertilizer amount adjustment. Through the quantitative fertilization device with stepless fertilizer amount adjustment proposed in the present application, a stepless fertilizer storage structure is set in the fertilization device to perform stepless adjustment of the fertilizer amount, so that the fertilizer amount adjustment is more flexible, and fertilizer waste and influence on crop growth are avoided. By setting a counting structure and a fertilizer driving structure adapted to the stepless fertilizer storage structure, through the structure and partial electronic control design, automatic fertilization is performed according to the distance traveled by the device, and it can be adjusted, so that the fertilizer amount and the fertilization interval can be adjusted steplessly, thereby improving the flexibility and accuracy of the fertilizer amount control and the fertilization interval control, and achieving the technical effect of improving the fertilization effect.

[0061] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
