TECHNICAL FIELD

[0001] The application relates to the technical field of wheat breeding auxiliary equipment, and in particular to a wheat breeding manual auxiliary fertilization device. BACKGROUND

[0002] A seedling raising tray is an important tool in seedling production. When it is applied to wheat breeding activities, it has the following advantages: 1. It is convenient to manage and observe, and the seedling raising environment such as temperature and humidity can be adjusted in time, which is beneficial to the growth of wheat seedlings; 2. The seeds are uniformly distributed in the tray, ensuring that each seed can obtain sufficient nutrients and water, thereby improving the germination rate and growth uniformity of the seeds.

[0003] During the seedling raising process, the environmental temperature and humidity need to be controlled, and the watering and fertilization plan should be reasonably arranged. In order to reduce the labor burden of workers, a fertilization device is usually used during the fertilization process. For example, the utility model patent with the publication number CN216853094U. It mainly includes a support frame, a stirring box and a water jet head. The water jet head is installed below the stirring box supported by the stirring box support frame. During the fertilization process, water and fertilizer are mixed in the stirring box, and then uniformly sprayed by the water jet head. The support frame is provided with rollers below, which facilitates the movement of the support frame and the fertilization of a large area of wheat.

[0004] The size of the fertilization device in the related art changes with the width of the nursery. For some small nurseries, it is more labor-intensive to fertilize by using the device, and the efficiency is relatively low in the actual operation process. Therefore, the fertilization device in the related art has a relatively narrow application range. UTILITY MODEL CONTENT

[0008] By adopting the technical scheme, for the large nursery, the rotating part is parallel to the horizontal part, and the supporting leg is perpendicular to the ground, at this time, the rotating wheel group on the supporting leg can assist the gantry to move, and then drive the fertilizing device to move, so as to complete the fertilizing work of the wheat in the large nursery. For the case that the nursery is small, the rotating part can be rotated to make the rotating part perpendicular to the ground and the supporting leg parallel to the ground, in this state, the rotating part supports the horizontal part, and the supporting member on the supporting leg forms a moving platform. The workers can take out the seedling tray in the nursery and place it on the moving platform, and the fertilizing device can fertilize the wheat by moving the seedling tray. According to different conditions, the working form of the fertilizer machine is changed, so as to expand the application range of the fertilizer machine.

[0009] Optionally, the supporting member is a cylindrical structure, and the supporting member is rotationally connected to the supporting leg about its own axis and is spaced apart in a direction perpendicular to its own axis.

[0010] By adopting the technical scheme, a plurality of supporting members are arranged to form a moving platform for supporting the seedling tray.

[0015] Optionally, the walking wheel group comprises a fixed shaft fixedly connected to the supporting leg and a rotating wheel rotationally sleeved on the fixed shaft.

[0016] By adopting the technical scheme, the rotating wheel is rotationally connected to the fixed shaft to realize the rotational connection between the rotating wheels and the supporting leg, thereby facilitating the movement of the gantry.

[0017] Optionally, the stabilizing disc is a disc-shaped structure, and the stabilizing disc is coaxially arranged on the fixed shaft.

[0018] By adopting the technical scheme, the stabilizing disc is installed on the fixed shaft, and the fixed shaft is used to install the stabilizing disc, thereby reducing the overall area occupied by the fertilizer machine.

[0019] Optionally, the stabilizing disc is threadedly connected with the fixing shaft, and the stabilizing disc is capable of moving along the length direction of the fixing shaft by rotating the stabilizing disc.

[0020] By adopting the technical scheme, in the fixed state of the fertilizer applicator (i.e. the state when the supporting legs are parallel to the ground), the stabilizing disc is capable of moving by rotating the stabilizing disc, so that the stabilizing disc is close to or away from the ground, thereby facilitating the response to the uneven ground.

[0021] Optionally, a limiting assembly is arranged between the rotating part and the horizontal part, the limiting assembly comprises two mounting plates and a connecting rod located between the two mounting plates, the two mounting plates are respectively connected with the rotating part and the horizontal part, and one of the two mounting plates is capable of sliding in a direction perpendicular to the rotating axis of the rotating part, the connecting rod is respectively connected with the two mounting plates at two ends, the rotating axis of the connecting rod is parallel to the rotating axis of the rotating part, and the mounting plate capable of sliding is provided with a locking screw for limiting the movement of the mounting plate.

[0022] By adopting the technical scheme, one of the two mounting plates is capable of sliding, and the sliding plate capable of sliding is adaptively slid during the rotation of the rotating part. When the position of the rotating part is determined, the mounting plate is limited by the locking screw, so that the rotation of the rotating part is limited, and the stability of the fertilizer applicator during the operation in the two working states is improved.

[0023] In summary, the present application has at least one of the following beneficial technical effects: when the large-scale nursery is fertilized, the supporting legs are perpendicular to the ground, the walking wheel set drives the gantry to move, and then drives the fertilizer device to move, thereby completing the fertilization of the wheat in the large-scale nursery. When the small-scale nursery is fertilized, the rotating part is rotated, so that the supporting legs are parallel to the ground, at this time, the supporting pieces on the supporting legs are closed to form a moving platform, the seedling tray moves on the moving platform, and the fertilizer device fertilizes the wheat in the seedling tray. By changing the state of the fertilizer applicator, the fertilization of the wheat in the nurseries of different scales is realized, and the application range of the fertilizer applicator is expanded.

DETAILED DESCRIPTION

[0029] The following will be described in detail in combination with the accompanying Figures 1-4 The application is further described in detail.

[0030] The embodiment of the application discloses a wheat breeding manual auxiliary fertilizing device.

[0031] Referring to Figure 1 and Figure 2 A wheat breeding manual auxiliary fertilizing device comprises a gantry 1, a walking trolley 2 installed on the gantry 1 and a fertilizing device 3 installed on the walking trolley 2 for spreading fertilizer. The gantry 1 comprises a crossbeam 11 and support legs 12, the support legs 12 are fixedly connected to the crossbeam 11 perpendicularly at positions close to both ends of the crossbeam 11, forming a door type structure. The walking trolley 2 is installed on the crossbeam 11 and can move along the length direction of the crossbeam 11. The crossbeam 11 comprises a horizontal part 112 and rotating parts 111, the rotating parts 111 are provided in two, and the two rotating parts 111 are respectively rotatably connected to both ends of the horizontal part 112. The support legs 12 are fixedly connected to the rotating parts 111, and an end of the support legs 12 close to the ground is provided with a walking wheel set 4 to facilitate the movement of the gantry 1 in a nursery.

[0032] Referring to Figure 1 and Figure 2 The support legs 12 are provided with support pieces 51, and the rotating rotating parts 111 can make the support legs 12 parallel to the ground. After the support legs 12 are parallel to the ground, the support pieces 51 on the two support legs 12 are closed to form a moving platform 5 for supporting the seedling tray 8 (wheat is cultivated in the seedling tray 8 in the embodiment). The seedling tray 8 can move on the moving platform 5 along the length direction of the horizontal part 112 and pass through the fertilizing machine. A worker can take out the seedling tray 8 in the nursery to make it pass through the moving platform 5. In the process that the seedling tray 8 passes through the moving platform 5, the seedling tray 8 moves relative to the fertilizing device 3, so that the fertilization of the wheat is realized. The wheat fertilizing device in the application has multiple working states, so that the wheat fertilization work in nurseries of different scales can be adapted, and the application range of the wheat fertilizing device is expanded.

[0033] Referring to Figure 1 and Figure 2The support 51 is a cylindrical structure, the support 51 is rotationally connected to the supporting leg 12 and is arranged at intervals along the length direction of the supporting leg 12. When the supporting leg 12 is perpendicular to the ground, the wheat fertilizing device is in a fixed state, and when the wheat fertilizing device is in the fixed state, the plurality of supports 51 on the two supporting legs 12 are arranged at intervals in the horizontal direction to form the moving platform 5. When the seedling tray 8 is placed on the support 51, the worker exerts force on the seedling tray 8, and the movement of the seedling tray 8 can drive the support 51 to rotate, thereby reducing the friction between the seedling tray 8 and the supporting leg 12, facilitating the movement of the seedling tray 8 by the worker. In order to improve the stability of the support 51 supporting the seedling tray 8, the support 51 can be arranged at intervals in multiple groups along the direction of the rotation axis of the support 51, and in the embodiment, two groups are arranged, and the seedling tray 8 can be arranged across the two groups of supports 51, thereby improving the stability of the seedling tray 8 during movement.

[0034] With reference to Figure 2 and Figure 3 The walking wheel set 4 includes a fixed shaft 41 and a rotating wheel 42. The fixed shaft 41 is welded vertically on the supporting leg 12, and the rotating wheel 42 is rotationally sleeved on the fixed shaft 41 to realize the rotational connection between the rotating wheel 42 and the supporting leg 12. The rotating wheel 42 rolls on the ground to drive the gantry 1 to move, thereby realizing the walking of the gantry 1.

[0035] With reference to Figure 1 and Figure 3 The fixed shaft 41 is welded on the side walls of the supporting legs 12 away from each other, and the end of the fixed shaft 41 away from the supporting leg 12 extends through the rotating wheel 42 to the side of the rotating wheel 42 away from the supporting leg 12. The end of the fixed shaft 41 away from the supporting leg 12 is welded with a stabilizing disc 6, and the stabilizing disc 6 is a disc-shaped structure. The stabilizing disc 6 is coaxially arranged with the fixed shaft 41. When the wheat fertilizing device is converted to the fixed state, the stabilizing disc 6 abuts against the ground to support the supporting leg 12. The end of the fixed shaft 41 close to the stabilizing disc 6 is provided with external threads, and the stabilizing disc 6 is provided with a threaded groove corresponding to the position of the fixed shaft 41. The fixed shaft 41 is threadedly connected in the threaded groove to fix the stabilizing disc 6. The diameter of the stabilizing disc 6 is smaller than the diameter of the rotating wheel 42, so as to reduce the interference between the stabilizing disc 6 and the ground during the walking of the rotating wheel 42 on the ground.

[0036] With reference to Figure 2 and Figure 4A limiting assembly 7 is arranged between the rotating part 111 and the horizontal part 112, the limiting assembly 7 comprises two mounting plates 71 arranged corresponding to the rotating part 111 and the horizontal part 112, and a connecting rod 72 located between the two mounting plates 71. The mounting plate 71 corresponding to the horizontal part 112 is slidingly connected to the horizontal part 112 along the length direction of the horizontal part 112. The connecting rod 72 is rotatably connected to the two mounting plates 71 at both ends, and the rotation axis between the connecting rod 72 and the mounting plate 71 is parallel to the rotation axis between the rotating part 111 and the horizontal part 112, so that the sliding plate can move following the rotation of the rotating part 111. The mounting plate 71 connected to the horizontal part 112 is provided with a locking screw 73 threadedly connected, and rotating the locking screw 73 can make the locking screw 73 abut against the horizontal part 112, and under the action of friction, the movement of the mounting plate 71 can be limited. After the position of the mounting plate 71 is fixed, the rotation between the rotating part 111 and the horizontal part 112 can be limited, thereby improving the stability of the wheat fertilizing device in the two states.

[0037] With reference to Figure 1 The fertilizing device 3 comprises a mixing box 31 and a plurality of spray heads 32 arranged below the mixing box, the fertilizer and water are mixed in the mixing box 31 during the fertilizing process, and then sprayed out by the spray heads 32 to realize the fertilizing of the wheat seedlings.

[0038] The implementation principle of the wheat breeding artificial auxiliary fertilizing device is that the gantry 1 and the moving trolley drive the fertilizing device 3 to move, realizing the fertilizing operation of the wheat in the nursery. Meanwhile, the cross beam 11 of the gantry 1 is divided into the rotating part 111 and the horizontal part 112, by rotating the rotating part 111, the supporting legs 12 mounted on the rotating part 111 can be parallel to the ground and combined to form the moving platform 5, in this state, the worker can place the seedling tray 8 on the moving platform 5, and by moving the seedling tray 8, the fertilizing operation of the wheat is realized, expanding the application range of the wheat fertilizing device.
