[0025] EMBODIMENT

[0026] As Figures 1 to 5As shown, the precise shallow fertilization needle device comprises a feeding shaft body 1 with an inner channel for connecting with an external support, an inner circular container 2 sleeved on the feeding shaft body for containing fertilizers, a ring body support frame 3 rotationally arranged on the feeding shaft body, an outer ring container 4 arranged on the ring body support frame and corresponding to the ring wall of the inner circular container, a plurality of needle heads 5 circumferentially and uniformly distributed on the radial outer wall of the outer ring container, and a conveying channel 6 fixedly connected to the inner circular container at one end and movably connected to the outer ring container at the other end, wherein the inner channel of the feeding shaft body is in communication with the inner circular container, and the needle heads and the conveying channel are both provided with control valves 7. The needle device is mainly applied in a fertilizer applicator and can be dragged and moved by a power equipment such as a tractor, and precise shallow fertilization can be performed in a specified area according to a set path. The fertilizers are mainly gas fertilizers or / and liquid fertilizers, the gas fertilizers can be carbon dioxide and ammonia, and the liquid fertilizers are generally liquid fertilizer products containing a nutrient element required by crops; the fertilizers can also be superfine solid fertilizers, which are superfine powders manufactured by special processes such as crushing and grinding of composite fertilizers with organic matter as a carrier. The external support 8 connected with the feeding shaft body can be used as an integral support and connection component and arranged on the power equipment such as a tractor, and a lifting device can be configured on the external support to adjust the height of the needle device. A gas pressure power source and a fertilizer tank and other auxiliary equipment can be configured on the fertilizer applicator or the power equipment, connected to the corresponding inner channel interface position on the feeding shaft body through pipelines 9, and pressure supply and fertilizer supply can be realized. In specific implementation, the inner circular container contains fertilizers with a corresponding capacity and ratio, under the movement of the power equipment, the needle heads at the bottom are used as fulcrums, the wheel structure composed of the outer ring container and the ring body support frame rolls in the moving direction, the corresponding needle heads are inserted into the next fertilization position, then the control valves are connected to the conveying channels and the needle heads at the specified position, a fertilization channel from the inner circular container to the shallow land (near the crop roots) through the conveying channels and the needle heads is formed, and the fertilizers are directly applied to the roots under the action of the pressure provided by the gas pressure power source, so that precise shallow fertilization is realized.

[0027] Specifically, in order to better transport the fertilizer, the transport channel is arranged at a radial position between the inner circular container and the outer ring container, and is fixedly connected with the outer wall of the inner circular container. The inner side wall of the outer ring container is movably connected with the transport channel in the form of a gas seal ring. That is, the inner side wall of the outer ring container is provided with an annular guide groove, and the bottom of the annular guide groove is provided with a one-way opening matched with the position of the needle head. The movable end of the transport channel is clamped in the annular guide groove through a sealing element, so that the outer ring container can also seal the channel during relative rotation. When the movable end of the transport channel is rotated to the position of the one-way opening, it can be connected. As a preferred embodiment, the transport channel is provided with three at the lower part and one at the upper part, thereby forming fertilizer channels in different directions to adapt to different conditions of fertilizer application, such as applying fertilizer to the shallow layer of the soil, applying fertilizer quantitatively on the surface of the soil, spraying air or mist from bottom to top on the back of the leaf, etc.

[0028] Specifically, in order to facilitate the opening and closing control of the corresponding fertilizer transport channel, the control valve is a pneumatic valve or an electromagnetic valve, which can be controlled by manual control or simple circuit control to open and close the valve at different positions. For example, when the needle head at the bottom is directly below the axis, the control valve on the needle head and the corresponding transport channel is opened, and the pressure of the air pressure power source can make the fertilizer sprayed from the needle head to the vicinity of the crop root in the soil. For another example, when the needle head is rotated to the upper transport channel, the control valve on the needle head and the corresponding transport channel is opened, so that the fertilizer is sprayed from bottom to top to the wax-free area on the back of the leaf, thereby enhancing the absorption of the fertilizer.

[0029] Specifically, the tip portion of the needle head is in an arc shape, which can facilitate the insertion of the needle head into the soil during movement, and can also improve the flexibility when encountering hard objects such as stones, so that the needle head can be relatively dislocated to avoid collision and damage.

[0030] Specifically, the supply shaft body is provided with a plurality of inner channels, the number of which is determined according to the types of fertilizers to be added. One of the inner channels is used to transmit the air pressure power source, and the remaining inner channels are used to transmit different fertilizers. By controlling the amount of different fertilizers transported, different proportions of fertilizer mixing can be achieved in the inner circular container.

Specifically, the hole plate feeder comprises a first fixed plate 11, an intermediate adjusting plate 12 and a second fixed plate which are arranged in sequence and closely along the coaxial center, a plurality of first perforations 13 are annularly arranged on the first fixed plate, a plurality of second perforations are arranged on the second fixed plate and correspond to the first perforations one by one, and a plurality of adjusting holes 14 are annularly arranged on the intermediate adjusting plate, the number of the adjusting holes is more than that of the first perforations, and the interval of adjacent adjusting holes is different from that of adjacent first perforations, thereby forming a staggered arrangement; when the intermediate adjusting plate is rotated to different positions, the number of the adjusting holes, the first perforations and the second perforations is different, so that the fertilizer supply with different proportions is realized, and the precise fertilization effect is realized.

[0032] As another alternative, the needle head is replaced by a spray head, and since the spray head does not need to be inserted into the soil, the device can be appropriately lifted as a whole during use. Through the arrangement of the spray head, liquid fertilizer can be atomized and sprayed from the crop root part upwards to realize precise atomization fertilization, the leaf back can also be sprayed and fertilized from bottom to top, and the device is also compatible with air fertilizer.

[0033] The above embodiment is only a preferred embodiment of the utility model, and does not limit the protection scope of the utility model, but any design principle of the utility model and changes made on the basis of non-creative labor should belong to the protection scope of the utility model.
