Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a pollen suspension sprayer for macadamia tree planting. Background Technology

[0002] Macadamia nuts, a globally renowned high-value economic nut crop, are rich in unsaturated fatty acids, protein, and various trace elements. Demand is strong in food processing and health and wellness sectors, leading to a continuously expanding market. However, the yield and quality of macadamia trees are highly dependent on pollination effectiveness during the flowering period.

[0003] In existing technologies, traditional manual pollination requires operators to use hand brushes and sprayers to apply or spray each flower individually. This method is not only time-consuming and labor-intensive, but also significantly increases planting costs, making it difficult to meet the needs of large-scale orchards. Furthermore, pollen is prone to sedimentation and its activity is easily destroyed in liquids. Ordinary stirring devices cannot guarantee the uniformity of the suspension, resulting in low pollen utilization and directly affecting fruit set rate and fruit quality. To solve the above problems, we propose a pollen suspension sprayer for macadamia tree planting. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pollen suspension sprayer for macadamia tree cultivation includes a mobile vehicle. A mixing tank is installed on the top side wall of the mobile vehicle. A support plate is installed on the inner side wall of the mixing tank. A housing is fixedly connected to the inner side wall of the support plate. A water inlet pipe is installed on the top side wall of the housing. A cover plate is detachably connected to the top of the water inlet pipe.

[0013] Compared with the prior art, this utility model has the following beneficial effects: This pollen suspension sprayer for macadamia tree planting adopts a dual-mode mixing mechanism of "mechanical stirring + airflow disturbance". The stirring sleeve drives the stirring plate to rotate to achieve basic mixing. At the same time, the gear rack drives the piston to generate compressed air, which is injected into the shell through the air transmission pipe to greatly reduce pollen precipitation. This solves the problem of local pollen concentration being too high or too low due to uneven mixing in traditional equipment. The pollen storage tank is equipped with a solenoid valve to realize quantitative pollen dispensing. Combined with the precise control of water volume by the floating ball and quantitative pointer, the error of the pollen-to-water ratio is reduced, avoiding the impact of improper concentration on pollen activity and pollination effect.

[0021] In this embodiment, the mixing mechanism 2 includes a stirring sleeve 21 rotatably connected to the top of the inner side wall of the housing 13. The outer side wall of the stirring sleeve 21 is provided with stirring plates 2995 arranged in a circumferential array. The top side wall of the moving vehicle 1 is provided with a protective shell 24. The top of the protective shell 24 is fixedly connected to the bottom of the housing 13. The bottom of the stirring sleeve 21 is provided with a first bevel gear 22 that penetrates the housing 13. The side wall of the protective shell 24 is rotatably connected with a drive shaft 25. One end of the drive shaft 25 is provided with a second bevel gear 23, which meshes with the first bevel gear 22.

[0022] Specifically, the drive shaft 25 rotates, which in turn drives the stirring sleeve 21 to rotate inside the housing 13 through the meshing of the second bevel gear 23 and the first bevel gear 22. The stirring plate 2995 on the outer wall of the stirring sleeve 21 rotates with the sleeve, stirring the pollen and water inside the housing 13 and accelerating the dispersion of pollen.

[0023] In this embodiment, a fixed plate 27 is provided on the top side wall of the mobile vehicle 1, and a first gear 26 is provided through the fixed plate 27 at the other end of the transmission shaft 25. An electric telescopic rod 28 is provided on one side wall of the support plate 12, and a gear rack 29 is provided at the telescopic end of the electric telescopic rod 28. The side wall of the gear rack 29 is slidably connected to the side wall of the support plate 12, and the gear rack 29 meshes with the first gear 26.

[0024] Specifically, when the electric telescopic rod 28 is activated, its telescopic end drives the gear rack 29 to slide back and forth along the side wall of the support plate 12. Furthermore, the gear rack 29 meshes with the first gear 26, thereby driving the transmission shaft 25 to rotate.

[0025] In this embodiment, a push rod 291 is provided at the other end of the gear rack 29, a piston 292 is provided on the side wall of one end of the push rod 291, a second sleeve 298 is fixedly connected to the inner side wall of the mixing barrel 18, a first sleeve 293 is provided at the other end of the second sleeve 298, the piston 292 is slidably connected inside the first sleeve 293, and the outer side wall of the piston 292 is in close contact with the inner side wall of the first sleeve 293.

[0026] Specifically, when the piston 292 is pulled out of the first sleeve 293, the two second rotating plates 297 open and the first rotating plate 295 closes, and external air enters the first sleeve 293 through the second slot 296.

[0027] In this embodiment, a first slot 294 is provided on one side wall of the first sleeve 293, and a first rotating plate 295 is rotatably connected to the side wall of the first slot 294. Two second slots 296 are provided on one side wall of the first sleeve 293, and a second rotating plate 297 is rotatably connected to the side wall of the second slot 296. A gas transmission pipe 299 is provided on one side wall of the second sleeve 298 through the mixing tank 18, and the other end of the gas transmission pipe 299 passes through the support plate 12 and is fixedly connected to the inside of the shell 13.

[0028] Specifically, when the piston 292 pushes into the first sleeve 293, the two second rotating plates 297 close and the first rotating plate 295 opens, and air is forced into the housing 13 through the second sleeve 298 and the air transmission pipe 299.

[0029] In this embodiment, the stirring sleeve 21 has two third slots 2991 on its side wall, the top side wall of the shell 13 has an observation window 2994, the top side wall of the shell 13 has a hole, and a floating ball 2992 is slidably connected to the inner side wall of the hole. A quantitative pointer 2993 is provided on the top side wall of the floating ball 2992.

[0030] Specifically, the water level is observed through the observation window 2994, and the water volume is precisely controlled by the quantitative pointer 2993 at the top of the floating ball 2992.

[0031] In this embodiment, a spraying mechanism 3 for spraying the suspension is provided on the side wall of the mixing tank 18. The spraying mechanism 3 includes a water pump 31 provided on the inner side wall of the mixing tank 18, a first water supply pipe 32 provided at the input end of the water pump 31, and the other end of the first water supply pipe 32 being fixedly connected to the housing 13. A pipe take-up wheel 34 is provided on one side wall of the mixing tank 18, and a second water supply pipe 33 is provided on the outer side wall of the pipe take-up wheel 34. One end of the second water supply pipe 33 passes through the mixing tank 18 and is fixedly connected to the output end of the second water supply pipe 33. A handheld telescopic sprayer 35 is provided at the other end of the second water supply pipe 33.

[0032] Specifically, the water pump 31 is started, and the pollen suspension in the housing 13 is pumped into the second water pipe 33 through the first water pipe 32, and then transported to the handheld telescopic sprayer 35 through the pipe outside the retractor 34. The operator holds the telescopic sprayer 35 and sprays it into the gaps between the branches and leaves so that the droplets can cover the stigma inside the petals. The mobile vehicle 1 moves slowly in coordination with the operator's walking speed to ensure that the entire tree can be sprayed evenly.

[0033] It should be noted that this utility model is a pollen suspension sprayer for macadamia tree planting. The user opens the feeding port of the pollen storage tank 16 and pours the dried macadamia pollen into the pollen storage tank 16. At this time, the solenoid valve 17 is in the closed state. Then, the cover plate 15 of the water inlet pipe 14 is opened, and a certain amount of clean water is injected into the housing 13. The water level can be observed through the observation window 2994. The amount of water is precisely controlled by the quantitative pointer 2993 at the top of the floating ball 2992. After the injection is completed, the cover plate 15 is closed. According to the pollen and water ratio requirements, the solenoid valve 17 on the inner side wall of the pollen storage tank 16 is opened. The pollen falls from the pollen storage tank 16 into the housing 13 below under the action of gravity and comes into contact with the clean water in the housing 13. After the preset time is reached, the solenoid valve 17 automatically closes, completing the quantitative addition of pollen.

[0034] When the electric telescopic rod 28 is activated, its telescopic end drives the gear rack 29 to slide back and forth along the side wall of the support plate 12. The gear rack 29 meshes with the first gear 26, thereby driving the transmission shaft 25 to rotate. This, in turn, through the meshing of the second bevel gear 23 with the first bevel gear 22, drives the stirring sleeve 21 to rotate within the housing 13. The stirring plate 2995 on the outer wall of the stirring sleeve 21 rotates with the sleeve, stirring the pollen and water within the housing 13 and accelerating pollen dispersion. Simultaneously, as the gear rack 29 slides back and forth, the push rod 291 at the other end drives the piston 292 to reciprocate within the first sleeve 293. When the piston 292 is pulled out of the first sleeve 293, the two second rotating plates 297 open and the first rotating plate 295 closes, allowing external air to enter the first sleeve 293 through the second slot 296. When piston 292 pushes into first sleeve 293, two second rotating plates 297 close and first rotating plate 295 opens. Air is forced into housing 13 through second sleeve 298 and air transmission pipe 299, forming microbubbles. As the bubbles rise in housing 13, they further agitate the liquid, making the pollen and water mix more evenly and preventing pollen from settling at the bottom. Water pump 31 is started, and the pollen suspension in housing 13 is pumped into second water transmission pipe 33 through first water transmission pipe 32 and delivered to handheld telescopic sprayer 35 through pipe outside retractor 34. The operator holds telescopic sprayer 35 and sprays deep into the gaps between branches and leaves, so that the droplets can cover the stigma inside the petals. Mobile vehicle 1 moves slowly in coordination with the operator's walking speed to ensure that the entire tree can be sprayed evenly.
