Description

Technical Field

[0001] The invention belongs to the technical field of fruit tree cultivation, and particularly relates to a fruit tree fertilization device and a zinc-enriched apple cultivation method. Background Art

[0002] Zinc is one of the trace elements required by the human body. It has certain effects on human growth and development, metabolism, promoting children's growth, maintaining appetite, and alleviating vision loss. Zinc-rich apples can be obtained by spraying amino acid chelated zinc solution.

[0003] Amino acid chelated zinc solution is a commonly used fertilizer and is packaged in bags. Each bag needs to be cut open and mixed for each use. This process is not only cumbersome but also easily causes waste of solution and environmental pollution.

[0004] At the same time, the existing spraying equipment often lacks an effective stirring and mixing structure when spraying the amino acid chelated zinc solution. This causes the solution to be easily mixed unevenly during the spraying process, thereby affecting the absorption effect of the nutrient elements by the crops. Moreover, the unevenly mixed solution may also cause the nozzle 10 to be blocked, reducing the working efficiency of the spraying equipment. Summary of the invention

A double-output shaft motor is fixedly connected to the vehicle frame. One output shaft of the double-output shaft motor drives a connecting shaft to rotate through a first transmission assembly, and the other output shaft drives the movable thorns plate to reciprocate through a second transmission assembly.

[0007] The first transmission assembly adopts a belt transmission mechanism.

[0008] A carriage is fixedly connected to the vehicle frame. The spraying rod is hinged to the carriage through a rotating shaft, and a groove for accommodating the spraying rod is arranged on the carriage; a driving assembly is arranged between the spraying rod and the carriage to drive the spraying rod to rotate.

[0009] The driving assembly includes a driving gear, a driving rack and a telescopic cylinder. The driving gear is fixedly connected to the rotating shaft, the cylinder body of the telescopic cylinder is fixedly connected to the carriage, the piston rod of the telescopic cylinder is fixedly connected to the driving rack, and the driving rack meshes with the driving gear.

[0010] A guide rod is fixedly connected to the movable thorns plate, and one end of the guide rod passes through the chemical dosing tank and extends out; the second transmission assembly includes a rocker arm, a connecting rod and a transmission shaft. The two ends of the connecting rod are respectively rotatably connected to the guide rod and the rocker arm; the transmission shaft is rotatably connected to the carriage, and the rocker arm is fixedly connected to the transmission shaft; the other output shaft of the double-output shaft motor drives the transmission shaft to rotate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The water tank wheel serves both as a water tank and a wheel body. During the traveling process, the rotation of the water tank wheel and the stirring shaft can ensure the uniform mixing of fertilizers. By moving the movable thorns in the medicine adding box, the outer packaging bag can be punctured, thus eliminating manual operation.

[0017] During the medicine preparation process, water in the water tank wheel is pumped into the medicine adding box by a water pump and then sprayed into the water tank wheel through a nozzle. Through this water flow circulation method, the mixing effect can be further improved, and by flushing the packaging bag in the medicine adding box with water, the waste caused by the residual liquid medicine in the packaging bag can be avoided.

[0018] The structure of the carriage can increase the loading capacity and protect the spraying rod through the groove (when not in spraying operation). The driving assembly and the second transmission assembly are linked through a movable shaft. When the spraying rod is in the vertical state (spraying operation), the movable thorns also move reciprocally accordingly; when the spraying rod is in the vertical state, the movable shaft is not connected to the transmission shaft, and the movable thorns do not perform reciprocating motion.

[0019] The structure of the paddle assembly can play a stirring role during the spraying process. After the spraying operation is completed, water is injected into the fixed paddle and the movable paddle, and by changing the position of the movable paddle, a "eccentric wheel" structure is formed; when it rotates, it can perform ramming operation on the ground. During the ramming operation, no water is added to the water tank wheel, which can increase the loading weight of the carriage.

[0020] This cultivation method can promote the absorption of nutrients by young fruits during the cell division period, thereby forming zinc-rich apples. After the late fruit expansion period, the zinc-rich nutrient elements are fully absorbed by the fruits, so that the apples achieve the effect of zinc-rich apples. Description of the Drawings

Detailed implementation manners

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1 As Figure 1-8 shown, a fruit tree fertilizing device includes a vehicle frame 1, a water tank wheel 2, a traveling wheel 3 and a spraying rod 4; the traveling wheel 3 and the spraying rod 4 are both arranged on the vehicle frame 1. There are two traveling wheels 3, and the two traveling wheels 3 are respectively driven by motors; steering is achieved by controlling the rotation speeds of the two traveling wheels 3.

[0024] A connecting arm 5 and a support arm 6 are fixedly connected to the vehicle frame 1. A stirring shaft 7 and a fixed shaft 8 are arranged inside the water tank wheel 2. The stirring shaft 7 and the fixed shaft 8 are coaxially arranged and rotatably connected. A paddle assembly 9 and a nozzle 10 are arranged on the stirring shaft 7, and a liquid flow channel communicating with the nozzle 10 is arranged on the stirring shaft 7. At both ends of the water tank wheel 2, a connecting shaft 11 and a connecting shaft 12 are rotatably connected respectively. The connecting arm 5 communicates with the liquid flow channel through the connecting shaft 11. The connecting arm 5 is rotatably connected with the connecting shaft 11, and the connecting shaft 12 is fixedly connected with the stirring shaft 7.

[0025] Both the fixed shaft 8 and the support arm 6 are fixedly connected to the connecting shaft 12. A water pump 13 is fixedly connected to the support arm 6. The end of the water suction pipe 14 of the water pump 13 passes through the connecting shaft 12 and the fixed shaft 8 and extends into the water tank wheel 2. The water pump 13 can pump out the water in the water tank wheel 2 through the water suction pipe 14.

[0026] A medicine adding box 15 is fixedly connected to the vehicle frame 1. A fixed thorns plate 16 and a movable thorns plate 17 are arranged inside the medicine adding box 15. The fixed thorns plate 16 is fixedly connected to the medicine adding box 15, and the movable thorns plate 17 is slidably connected to the medicine adding box 15. A medicine adding cover 18 is connected to the medicine adding box 15. The medicine adding cover 18 and the medicine adding box 15 can be connected by a threaded manner. The fertilizer packaging bag is put into the medicine adding box 15 through the medicine adding cover 18, and the packaging bag is punctured through the cooperation of the fixed thorns plate 16 and the movable thorns plate 17, thus eliminating manual removal. When the punctured packaging bags accumulate to a certain number, they are taken out by opening the medicine adding cover 18.

[0027] The medicine adding box 15 communicates with the connecting arm 5. Both the medicine adding box 15 and the spraying rod 4 are communicated with the water outlet pipe of the water pump 13 through pipelines. A three-way valve is arranged at the communicating place, and the water flow direction can be controlled according to needs. When preparing medicine, the three-way valve is controlled to make the water outlet pipe communicate with the medicine adding box 15. The water pump 13 pumps the water in the medicine adding box 15 into the medicine adding box 15. After flushing the packaging bags (punctured) in the medicine adding box 15, it then passes through the connecting arm 5, the connecting shaft 11 and the stirring shaft 7 in sequence, and sprays out from the nozzle 10 and flows back into the medicine adding box 15 again. When carrying out spraying operation, the three-way valve is controlled to make the water outlet pipe communicate with the spraying rod 4. The water pump 13 pumps the water in the medicine adding box 15 to the spraying rod 4 for pesticide spraying operation.

[0028] Specifically: A lid can be arranged on the water tank wheel 2, and water is added into the water tank wheel 2 by opening the lid; or water can be added into the water tank wheel 2 by opening the medicine adding cover 18 and through the medicine adding cover 18.

[0029] A double-output shaft motor 19 is fixedly connected to the vehicle frame 1. One output shaft of the double-output shaft motor 19 drives the connecting shaft 12 and the stirring shaft 7 to rotate through a first transmission assembly 20; the other output shaft drives the movable thorns plate 17 to reciprocate through a second transmission assembly 21, thereby puncturing the packaging bag.

[0030] The specific usage process is as follows: Water is added by opening the chemical addition cover 18, and the water flows into the water tank wheel 2 through the chemical addition tank 15, the connecting arm 5, and the connecting shaft 11. After the required amount of water is added to the water tank wheel 2, the fertilizer packaging bag is loaded into the chemical addition tank 15. Finally, the dual-output shaft motor 19 and the water pump 13 are started, so that the stirring shaft 7 rotates and the movable thorn plate 17 reciprocates to prepare the medicine.

[0031] After the medicine preparation is completed, the three-way valve is controlled to change the water flow direction; the motor of the traveling wheel 3 is started to drive the whole to move for pesticide spraying. During the traveling process, the rotation of the water tank wheel 2 and the stirring shaft 7 can ensure the uniform mixing of the fertilizer.

[0032] Furthermore, the first transmission component 20 adopts a belt transmission mechanism, that is, belt pulleys are fixed on both the connecting shaft 12 and the output shaft, and the two belt pulleys are connected by a belt.

[0033] Furthermore, a carriage 22 is fixedly connected to the vehicle frame 1. Agricultural items can be loaded in the carriage 22, which has a certain loading capacity. The spraying rod 4 is hinged to the carriage 22 through a rotating shaft. The spraying rod 4 is fixedly connected to the rotating shaft, and the rotating shaft is hinged to the carriage 22. Specifically, there are two spraying rods 4. The two spraying rods 4 are connected through a rotating shaft, and several atomizing nozzles are provided on each spraying rod 4.

[0034] A groove 220 for accommodating the spraying rod 4 is provided on the carriage 22; a driving component 23 is provided between the spraying rod 4 and the carriage 22. When spraying operations are carried out, the spraying rod 4 is driven to rotate by the driving component 23 so that the spraying rod 4 is in a vertical state; when spraying operations are not required, the spraying rod 4 is driven to rotate in the reverse direction by the driving component 23 so that the spraying rod 4 enters the groove 220, thus playing a protective role.

[0035] Furthermore, the driving component 23 includes a driving gear 230, a driving rack 231, and a telescopic cylinder 232. The driving gear 230 is fixedly connected to the rotating shaft. The cylinder body of the telescopic cylinder 232 is fixedly connected to the carriage 22, and the piston rod of the telescopic cylinder 232 is fixedly connected to the driving rack 231. The driving rack 231 meshes with the driving gear 230. The movement of the driving rack 231 is driven by the telescopic piston rod, and the driving rack 231 meshes with the driving gear 230 to drive the rotating shaft and the spraying rod 4 to rotate.

[0036] Furthermore, a guide rod 24 is fixedly connected to the movable thorn plate 17, and one end of the guide rod 24 passes through the chemical addition tank 15 and extends out. The second transmission component 21 includes a rocker arm 210, a connecting rod 211, and a transmission shaft 212. The two ends of the connecting rod 211 are respectively rotatably connected to the guide rod 24 and the rocker arm 210, that is, a crank and connecting rod mechanism is formed.

[0037] The transmission shaft 212 is rotatably connected to the carriage 22, and the rocker arm 210 is fixedly connected to the transmission shaft 212; the other output shaft of the dual-output shaft motor 19 drives the transmission shaft 212 and the rocker arm 210 to rotate, thereby driving the movable thorns plate 17 to reciprocate and puncture the packaging bag.

[0038] Further, the second transmission assembly 21 further includes a movable shaft 213, and the other output shaft of the dual-output shaft motor 19 is connected to the transmission shaft 212 through the movable shaft 213.

[0039] The movable shaft 213 is slidably connected to the carriage 22, and the corresponding arc-shaped groove 221 is provided on the carriage 22; the movable shaft 213 and the other output shaft are driven by a belt, and the corresponding belt pulleys are fixed on the output shaft and the movable shaft 213. Bevel gears 214 are provided on both the movable shaft 213 and the transmission shaft 212, and the two bevel gears 214 are in meshing transmission; when the two bevel gears 214 are meshed, the transmission shaft 212 drives the movable thorns plate 17 to reciprocate; when the two bevel gears 214 are separated, the movable thorns plate 17 lacks power input and does not perform reciprocating motion.

[0040] A push-up plate 215 and a push-down plate 216 are fixed on the driving rack 231, and the movable shaft 213 is located between the push-up plate 215 and the push-down plate 216. That is, when the driving rack 231 moves upward, the spraying rod 4 turns to the vertical state; and the push-down plate 216 pushes the movable shaft 213 to slide upward, so that the two bevel gears 214 are meshed, and the transmission shaft 212 drives the movable thorns plate 17 to reciprocate. When the driving rack 231 moves downward, the spraying rod 4 turns into the groove 220; and the push-up plate 215 pushes the movable shaft 213 to slide downward, so that the two bevel gears 214 are separated.

[0041] Further, the paddle assembly 9 includes a fixed paddle 90 and a movable paddle 91. The fixed paddle 90 is fixedly connected to the stirring shaft 7, and both ends of the movable paddle 91 are rotatably connected to the stirring shaft 7 through connecting rings 92 respectively; an adjusting assembly 93 is provided between one of the connecting rings 92 and the stirring shaft 7. During the process of medicine preparation and spraying operation, the angle between the fixed paddle 90 and the movable paddle 91 is 180 degrees; that is, the liquid in the water tank wheel 2 is stirred by the fixed paddle 90 and the movable paddle 91.

[0042] When it is necessary to compact the ground, the position of the movable paddle 91 is changed so that the angle between the movable paddle 91 and the fixed paddle 90 is less than 90 degrees, forming a structure similar to an eccentric wheel. At this time, when the stirring shaft 7 drives the fixed paddle 90 and the movable paddle 91 to rotate, vibration will be generated, thereby compacting the ground.

[0043] Further, a cover plate 25 is detachably connected to the water tank wheel 2; by opening the cover plate 25, the adjusting assembly 93 can be adjusted, thereby changing the position of the movable paddle 91. The adjusting assembly 93 includes a worm gear 930 and a worm 931. The worm gear 930 is fixedly connected to the connecting ring 92, the worm 931 is rotatably connected to the stirring shaft 7, and a corresponding support seat is provided on the stirring shaft 7. The worm 931 meshes with the worm gear 930. By rotating the worm 931, the position of the movable paddle 91 can be changed.

[0044] Further, a water adding cavity and a water adding port communicating with the water adding cavity are provided on both the fixed paddle 90 and the movable paddle 91, and a plug 94 is provided at each water adding port. By opening the plug 94, water is added into the water adding cavity, thereby increasing the weight and improving the ramming effect.

[0045] With such a structural arrangement, during the ramming operation, no water is added to the water tank wheel 2, which can increase the loading weight of the carriage 22, and heavier items can be loaded in the carriage 22.

[0046] Embodiment 2 On the basis of Embodiment 1, this embodiment provides a method for cultivating zinc-rich apples. After the apples drop their flowers, the amino acid chelated zinc solution is sprayed on the fruits for the first time using the fruit tree fertilizing device in Embodiment 1, and then the second and third sprays are carried out at intervals of 10 days respectively.

[0047] The dilution ratio of the first amino acid chelated zinc solution is 1000 times, the dilution ratio of the second time is 800 times, and the dilution ratio of the third time is 600 times.

[0048] Specifically: the above fertilization process needs to be completed before the fruits are bagged; at the same time, in order to reduce the competition for zinc elements between the fruit trees and the fruits, organic zinc fertilizer can be applied to the roots of each fruit tree or zinc sulfate can be applied to each fruit tree in September - October every year.
