[0029] The present application provides a wheat foliar fertilizer spraying device, as shown in Figures 1 to 5 The wheat foliar fertilizer spraying device comprises two oppositely arranged hinged plates 1, a support side plate 2, a spring arm 3, a rotating shaft support arm 4, a bearing base plate 5, a fertilizer preparation assembly 6, a conduit 7 and a spraying assembly 8. One side of the two oppositely arranged hinged plates 1 is provided with a connecting surface, and a through hole is formed in the surface of the other side, and the two hinged plates 1 are movably connected with a hub 10 through the through hole.

One side of the spraying assembly 8 is fixedly installed in the fertilizer preparation assembly 6, and the top of the spraying assembly 8 is adapted to the other end of the conduit 7.

[0030] Specifically, the articulated plate 1 serves as a connection hub, closely fitted on one side to the hub 10, ensuring stable docking of the two, building the basic structure of the entire device, the support side plate 2 on the side of the articulated plate 1 is perpendicular, providing reliable lateral support for the overall structure, ensuring the stability of the device in complex operating environments. The spring arm 3 connected to it is connected to the hub 10, which can sense the ups and downs of the ground when the device is driving on the uneven soil of the wheat field, and through its own stretching and deforming, it can efficiently absorb and buffer the shock energy, greatly reducing the impact on the hub 10, and then ensuring that the entire device can move smoothly and smoothly, perfectly adapting to the complex soil conditions of the wheat field. The top of the hub 10 is installed with a bearing base plate 5 for carrying a fertilizer assembly component 6. In the traditional fertilization process, due to the limited amount of fertilizer reserves, the fertilization process needs to be frequently interrupted, and the farmer needs to constantly add fertilizer, which not only consumes a lot of manpower, but also frequently hinders the progress of the spraying process, seriously slowing down the overall spraying efficiency. Therefore, the large-capacity fertilizer assembly component 6 is directly installed on the device, so that it can continuously produce fertilizer during the operation process, providing sufficient fertilizer for the spraying operation, and improving the fertilization efficiency.

[0031] In some embodiments, the bearing base plate 5 can include side ears 501 and bent ends 502; wherein the side ears 501 are arranged on the surface of the bearing base plate 5 close to the shaft support arm 4, and the bearing base plate 5 is movably connected with the shaft support arm 4 through the side ears 501; the bent ends 502 are arranged on one end of the bearing base plate 5 close to the side ears 501, and are fixedly connected with the fertilizer assembly component 6, and abut with the shaft support arm 4.

[0032] Further, the number of side ears 501 is two, and they are symmetrically distributed on both sides of the bearing base plate 5 corresponding to the shaft support arm 4. One side surface of the two side ears 501 is provided with a hole, and the bearing base plate 5 is movably connected with the shaft support arm 4 through the hole.

[0033] Please refer to Figure 1 The connected bearing base plate 5 can move in the sliding groove on both sides of the shaft support arm 4, and is fixedly installed on the shaft support arm 4 by means of bolts, so that the height of the bearing base plate 5 can be appropriately changed, so that it can be adjusted according to the growth height of the wheat.

[0034] In the example embodiment, the fertilizer preparation assembly 6 can include a bearing support 601, a drive box 602, a fertilizer box 603, and an inclined support plate 604; wherein two bearing supports 601 are fixedly installed on the surface of the bearing base plate 5 away from the shaft support arm 4; the drive box 602 is fixedly installed on the upper surface of the bearing base plate 5 and located between the two bearing supports 601; the outer wall of the fertilizer box 603 is fixedly installed on the end of the bearing support 601 away from the bearing base plate 5; and the inclined support plate 604 is movably connected to the connecting rod connecting the two ends of the bearing support 601 away from the bearing base plate 5 through a bearing and connected to the outer wall of the surface of the fertilizer box 603.

[0035] Further, the upper surface of the drive box 602 is movably connected with a stirring rod 605, one end of the stirring rod 605 penetrates into the interior of the fertilizer box 603, the front middle part of the drive box 602 is connected with a drive shaft 606, one end of the fertilizer box 603 is connected with the conduit 7, and the conduit 7 is spirally overlapped on the outer wall of the fertilizer box 603.

[0036] Specifically, according to Figure 1 , Figure 2 and Figure 3 , the two bearing supports 601 are fixedly installed on the surface of the bearing base plate 5 away from the shaft support arm 4, establishing a stable support structure to lay a solid foundation for the installation and operation of subsequent assemblies, the drive box 602 is fixedly installed on the upper surface of the bearing base plate 5 and located between the two bearing supports 601, respectively providing power for the stirring rod 605 and the drive shaft 606.

[0037] One end of the stirring rod 605 penetrates into the interior of the fertilizer box 603, in the process of continuous fertilization, the stirring rod 605 rotates at a constant speed to continuously stir and mix the fertilizer in the box by relying on the continuous power of the drive box 602, which can effectively break the solidification state of the fertilizer that may occur due to static placement, resolve the problem of poor flow caused by too thick fertilizer, ensure that the fertilizer always maintains in the appropriate humidity range, and make it have good flowability and sprayability, thereby providing strong guarantee for precise and efficient fertilization. At the same time, the drive shaft 606 also drives the rotation of the subsequent spraying link to output kinetic energy.

[0038] In the example embodiment, the spraying assembly 8 can include a hinged wheel 801, a support sleeve column 802, a spraying funnel 803, and a spray pipe 804; wherein the hinged wheel 801 is in a circular ring structure, a partition plate 805 is arranged along the diameter of the circular ring structure, and the partition plate 805 is connected with the drive shaft 606; the support sleeve column 802 is connected to one side of the hinged wheel 801; the rod part of the spraying funnel 803 penetrates into the support sleeve column 802; and the spray pipe 804 is arranged on the outer arc surface of the spraying funnel 803.

[0039] Further, the side surface bottom of the partition plate 805 is provided with a connecting cavity, and a universal seat 806 is fixedly installed in the connecting cavity.

[0040] Still further, one end of the spherical joint rod 807 is fixedly provided with a concave part 808, and the outer arc surfaces of the support sleeve column 802 are provided with slot holes 809, the concave part 808 is connected to the slot holes 809 through bearings, and the bottom end of the spraying funnel 803 is connected to the concave part 808, and the inner arc surface of the spray pipe 804 is provided with an auxiliary assembly 9.

[0041] Please continue according to Figure 3 As shown in the figure, the driving shaft 606 is connected with the articulated wheel 801 at one end, when the driving shaft 606 starts to rotate under the driving of the power, the articulated wheel 801 continuously and stably rotates in the same direction, the partition plate 805 is fixedly connected with the universal seat 806 on the surface of the articulated wheel 801, and the universal seat 806 rotates synchronously with the articulated wheel 801, the spherical joint rod 807 is connected at the front end of the universal seat 806, and the spherical joint rod 807 can change flexibly at any angle and any position under the bearing and constraint of the universal seat 806 due to the spherical structure design, and the concave part 808 connected at the distal end of the spherical joint rod 807 moves around the articulated wheel 801 in a graceful detour under the driving of the spherical joint rod 807.

[0042] The concave part 808 is installed at the bottom end of the spraying funnel 803 at both sides, and the two are connected through a movable shaft, so that the concave part 808 and the spraying funnel 803 can be connected and matched, and a certain relative movement space is reserved at the same time, and the spraying funnel 803 is arranged in the inside of the support sleeve column 802, and it is worth noting that the transverse slot holes 809 are provided at the outer arc surfaces of the support sleeve column 802, which avoids the synchronous rotation of the support sleeve column 802 with the concave part 808, since the connection between the concave part 808 and the spraying funnel 803 is a movable shaft, the motion track of the concave part 808 presents an up-down curve range under the driving of the spherical joint rod 807, and at the same time, the connecting shaft of the concave part 808 can only move left and right in the transverse slot hole 809 due to the constraint of the transverse slot hole 809, so that the spraying funnel 803 connected at the top can rotate left and right synchronously, which greatly expands the spraying range, ensures that the fertilizer can be uniformly and accurately sprinkled in the effective absorption area of the wheat, and provides sufficient nutrients for the vigorous growth of the wheat.

[0043] In the example embodiment, the auxiliary assembly 9 can include an acceleration pipeline 901 and a deceleration pipeline 902; wherein the acceleration pipeline 901 is sleeved in the inner arc surface of the spray pipe 804; the tail end of the deceleration pipeline 902 is connected in the spray pipe 804, and the deceleration pipeline 902 coincides with the central axis of the acceleration pipeline 901.

[0044] Further, the front end of the acceleration pipeline 901 is provided with a conical boss 903, the inner arc surface of the acceleration pipeline 901 is provided with a conical path 904, the inner arc surface of the conical boss 903 is provided with a cylindrical path 905, the tail end of the deceleration pipeline 902 is provided with a conical groove 906, the conical groove 906 is matched with the tail end cylindrical path 905, and the inner arc surface of the deceleration pipeline 902 is provided with a discharge hole 907 at one side edge.

[0045] As shown in Figure 4 The hole diameter of the deceleration pipeline 902 gradually increases along the direction away from the acceleration pipeline 901 and close to the discharge hole 907, which is beneficial to reduce the flow speed of the irrigation water and ensure the uniform mixing of the fertilizer after entering the deceleration pipeline 902 from the conical groove 906, and ensure the flow stability of the irrigation fertilizer solution.

[0046] The size of the hole diameter of the cylindrical path 905 of the acceleration pipeline 901 is set to be one tenth of the size of the conical path 904 of the acceleration pipeline 901, that is, the size of the hole diameter of the cylindrical path 905 of the acceleration pipeline 901 is one tenth of the size of the hole diameter of the spray pipe 804. In this way, the outlet section of the acceleration pipeline 901 and the spray pipe 804 have sufficient pressure difference, so that the fertilizer obtains sufficient flow rate at the outlet of the acceleration pipeline 901, effectively avoids the blockage of the fertilizer and is beneficial to shorten the spraying time. At the same time, the greater the flow rate of the irrigation water at the outlet of the acceleration pipeline 901, the greater the suction force generated at the spraying funnel 803, which is beneficial to ensure the rapid discharge of the fertilizer and avoid pipeline blockage.

[0047] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
