Description

Technical Field

[0001] The invention relates to a fertilizer applicator and to the field of agricultural planting equipment, in particular to a corn proportioning fertilizer applicator in an intercropping mode. Background Art

[0002] For tall crops like corn, they can be intercropped with a variety of short crops, which can make more rational use of planting space and increase economic benefits. Fertilization operations including root fertilizer and leaf fertilizer for crops can facilitate fertilization at different stages of crops to ensure crop yields. However, unlike traditional planting, fertilization in intercropping must also consider plant distribution factors.

[0003] On the one hand, foliar fertilizer spraying of different crops needs to consider the crops' demand for nutrients, and on the other hand, the height of the crop leaves should be covered as much as possible. The existing technology usually adopts a single nozzle structure, and the spraying height and spraying amount are changed through the operator's subjective judgment and manual control. During this period, a lot of blank areas that are not convenient for switching spraying are wasted.

[0004] To this end, those skilled in the art have proposed a corn ratio fertilizer applicator in an intercropping mode, which can facilitate the ratio adjustment and control of foliar fertilizer spraying on intercropped crops and perform height and quantity adaptation operations on different crops. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a corn proportioning fertilizer applicator under the intercropping mode. A height-adjusting slide rail on which more than one atomizing nozzle can be installed is arranged at the end of the conveying pipe. The rotating sleeve and the angle adjustment rod are cooperated to realize the synchronous adjustment of the operating angles of multiple atomizing nozzles. In intercropping, foliar fertilizer spraying operations can be carried out on crops of different heights respectively, and the spraying angle and spraying amount of the atomizing nozzle can be conveniently controlled separately.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a corn ratio fertilizer applicator under intercropping mode, including a delivery pipe and an atomizing nozzle, the atomizing nozzle is arranged at the end of the delivery pipe, and liquid fertilizer is delivered to the atomizing nozzle through the delivery pipe for atomization spraying to cover the leaf height of the crop.

[0007] Unlike the planting of traditional crops, the plant heights of different crops in the intercropping planting mode vary greatly. The traditional method of foliar fertilizer spraying requires manual observation and movement of the atomizing nozzle to cover the plants in a targeted manner. However, different crops have different nutritional requirements at different stages. In addition, manual conversion of the spraying height results in fertilizer waste and is difficult to control the spraying amount. In order to facilitate foliar fertilizer spraying of crops in the intercropping mode, technical personnel in this field have proposed a corn ratio fertilizer applicator in the intercropping mode.

[0008] The end of the delivery pipe is fixedly connected with a hard pipe, the side of the hard pipe is fixedly connected with a height adjustment slide rail, the atomizing nozzle is slidably arranged inside the height adjustment slide rail, and the height adjustment slide rail is arranged at the end of the delivery pipe through the hard pipe, which not only facilitates the arrangement of more than one atomizing nozzle, but also facilitates the adjustment of the setting height of the atomizing nozzle, so as to facilitate the adjustment of the working height of intercropping crops at different heights.

[0009] A rotating sleeve is rotatably arranged on the outer side of the hard tube, and an angle adjustment rod is slidably arranged on the side of the rotating sleeve. The angle adjustment rod is slidably connected to the atomizing nozzle. In the intercropping mode, the height of the atomizing nozzle is moved according to the crop height distribution. At the same time, the inclination angle is adjusted by the angle adjustment rod, so as to facilitate the atomizing nozzle to change the working angle when the rotating sleeve is rotated.

[0010] Preferably, a stop valve is provided on the inner side of the atomizing nozzle, and one end of the stop valve passing through the side wall of the atomizing nozzle is fixedly connected to an L-shaped rod. When the rotating sleeve is rotated, the L-shaped rod is pushed to rotate at an angle, thereby adjusting the opening angle of the stop valve and controlling the spraying amount of the atomizing nozzle.

[0011] Preferably, a fixed sleeve is fixedly connected to the side of the atomizing nozzle, and a first spring is provided on the inner side of the fixed sleeve to press against the L-shaped rod. The L-shaped rod pressed against by the first spring can reset the stop valve after losing the squeezing of the rotating sleeve, thereby facilitating the control of the spraying amount of the atomizing nozzle.

[0012] Preferably, a guide rod is fixed parallel to one side of the hard tube, and the rotating sleeve is slidably connected to the guide rod. The rotating sleeve can be raised and lowered and positioned along the guide rod, thereby expanding the height adjustment range of the equipment.

[0013] The end of the atomizing nozzle is hingedly connected to a first slider, and the atomizing nozzle is slidably arranged on the inner side of the height-adjusting slide rail through the first slider. A spherical hinge structure is adopted between the atomizing nozzle and the first slider, so that the atomizing nozzle can not only swing in the left and right directions when the rotating sleeve rotates, but also perform spraying operations at an inclined angle on the crop leaves.

[0014] Preferably, a locating pin is inserted into the side of the first slider, and a second spring is sleeved on the side of the locating pin. The locating pin presses against the height-adjusting slide rail under the elastic force of the second spring to achieve positioning. The first slider is moved along the height-adjusting slide rail to adjust the installation height of the atomizing nozzle by pressing the locating pin to cancel the limit.

[0015] Preferably, a lever is fixedly connected to the side of the positioning pin, and a positioning groove is provided on the side of the first sliding block corresponding to the positioning pin and the lever. The lever extends outside the rotating sleeve to facilitate manual adjustment of the installation height of the atomizing nozzle.

[0016] Preferably, a connecting hose is fixedly connected between the atomizing nozzle and the hard pipe, and the atomizing nozzle connected by the connecting hose can be easily adjusted in installation height and working angle.

[0017] A feeding pipe is fixedly connected to the side of the connecting hose, and the separate feeding pipe delivers nutrient liquid to the relative atomizing nozzles, thereby distinguishing the differences in the requirements of different crops for nutrient components.

[0018] Preferably, the end of the feeding pipe away from the atomizing nozzle is connected to a material box, and a booster pump is provided inside the material box. The booster pump is used to pressurize the liquid material in the material box, and the pressurized liquid material is directly transported to the corresponding atomizing nozzle through the feeding pipe for atomization spraying.

[0019] Preferably, a slide groove is provided on the side surface of the rotating sleeve symmetrically and parallel to the atomizing nozzle, a second slider is slidably provided inside the slide groove, and one end of the angle adjustment rod is fixedly connected to the second slider.

[0020] Two second sliders are correspondingly arranged in the two slide grooves, and the angle adjustment rod is installed through the two second sliders, so that the angle adjustment rod with different inclination angles can be formed through the positions of the two second sliders. When the rotating sleeve rotates, the angle adjustment rod pushes the atomizing nozzle to make the atomizing nozzle deflect along the angle of the angle adjustment rod. When the coverage range of crop leaves is different, the deflection amount of the atomizing nozzle can be controlled by adjusting the inclination angle of the angle adjustment rod.

[0021] Preferably, one end of the angle adjustment rod away from the second slider passes through the atomizing nozzle and is slidably connected thereto, and the side sliding sleeves of the intersecting ends of the two angle adjustment rods are provided with connecting blocks, and the two angle adjustment rods are connected by the connecting block, and the two angle adjustment rods can be stretched in length as the position of the second slider is adjusted.

[0022] The present invention discloses a corn proportioning fertilizer applicator in an intercropping mode, which has the following beneficial effects:

[0023] 1. The corn proportioning fertilizer applicator in the intercropping mode sets the atomizing nozzle by sliding the slide rail at the end of the conveying pipe. The installation height of the two atomizing nozzles can be adjusted according to the needs of use. In addition, a rotating sleeve and an angle adjustment rod are provided. After the height of the atomizing nozzle is installed, the atomizing nozzle is pushed by rotating the rotating sleeve to deflect the angle, so that the atomizing nozzle is rotated to the required angle. At the same time, the spraying amount of the atomizing nozzle can be controlled, and targeted spraying operations can be carried out on the leaves of crops with different densities to reduce fertilizer loss. In the intercropping mode, foliar fertilizer spraying of more than one crop can be carried out in a targeted manner.

[0024] 2. The corn proportioning fertilizer applicator under the intercropping mode is equipped with a height-adjusting slide rail on the side of the hard pipe for installing the atomizing nozzle. When in use, the height of the atomizing nozzle is set according to the height of the crop plants. It is aimed at the synchronous spraying of foliar fertilizers of various crops under the intercropping mode. In addition, an L-shaped rod fixed to the stop valve is arranged on the side of the atomizing nozzle. The opening of the stop valve is controlled by rotating the angle of the sleeve, and then the spraying amount of different atomizing nozzles is controlled. Not only can the foliar fertilizer spraying of intercropped crops be carried out synchronously, but also the loss of fertilizer can be minimized.

[0025] 3. In the intercropping mode, the corn proportioning fertilizer applicator has a rotating sleeve sleeved on the outer side of the hard tube, and an angle adjustment rod is slidably arranged on the side of the rotating sleeve. The angle adjustment rod is slidably connected to the atomizing nozzle. When in use, the rotating sleeve can be rotated to push the atomizing nozzle to change the angle, thereby changing the spraying angle and spraying amount of the atomizing nozzle to adapt to the foliar fertilizer spraying of crop density in different areas and reduce fertilizer loss.

[0026] 4. In the intercropping mode, the two angle adjustment rods are slidably installed through the second sliders, and the connecting blocks are slidably arranged on the sides of the cross ends of the two angle adjustment rods. The connecting blocks ensure that the two second sliders form angle adjustment rods with different inclination angles when adjusted, so that the deflection angles of the two atomizing nozzles can be controlled during use to cover different ranges of plant leaves.

The liquid fertilizer is delivered to the atomizing nozzle 2 through the delivery pipe 1 for atomization spraying to cover the leaf height of the crop.

[0038] Different from the planting of traditional crops, the plant heights of different crops in the intercropping planting mode vary greatly. The traditional method of foliar fertilizer spraying requires manual observation and movement of the atomizing nozzle 2 to cover the plants in a targeted manner.

The L-shaped rod 8 pressed against by the first spring 10 can reset the stop valve 7 after losing the squeezing of the rotating sleeve 5, so as to facilitate the control of the spraying amount of the atomizing nozzle 2.

[0043] Preferably, a guide rod 11 is fixed parallel to one side of the hard tube 3, and the rotating sleeve 5 is slidably connected to the guide rod 11.
