Description

Technical Field

[0001] The invention relates to the technical field of mechanical automation, and in particular to a vegetable planting and maintenance device, specifically a lettuce growth management machine. Background Art

[0002] At present, with the continuous improvement of people's living standards, the vigorous development of science and technology, and the continuous reduction of manual labor, agricultural machinery is becoming more and more popular among people. Lettuce growth management machine is one of the more popular agricultural machinery in the market. Now some machines related to lettuce have been launched one after another, but there are very few machines for lettuce growth management and they are all single-function machines for a certain aspect.

[0003] At present, the domestic lettuce growth management process is relatively mature. Some practical problems that may arise during the lettuce growth process still require a lot of labor for large-scale lettuce planting. For example, lettuce needs to maintain sufficient air permeability in the soil, and it needs to be loosened manually at regular intervals; the work of removing the bottom leaves of lettuce also needs to be done manually; the fertilization and watering of lettuce are also inseparable from human labor, that is, the low loading rate of fertilizer transportation, low efficiency of loosening the soil, and the long-term bending over for leaf removal, which consumes a lot of body energy, all of which restrict the growth and development of lettuce. Although in today's information and industrial automation technology, the automation application of modern agricultural machinery has also made some great progress, but the mechanization and automation of equipment in the lettuce growth process is generally not high, and the equipment of most production bases is not developed, especially the automation of the entire lettuce growth management is not high, and it needs to be improved.

[0004] In order to solve the above problems, it is necessary to research and design an automated lettuce growth management machine with stronger applicability and higher degree of automation, which can be used for watering, fertilizing and leaf removal of lettuce, so as to replace the tedious manual work and solve the problem of high labor intensity and low efficiency. Summary of the invention

[0005] The present invention aims to solve the problems existing in the above-mentioned prior art and provide a lettuce growth management machine to solve the problem of low automation level in maintenance processes such as loosening soil, fertilizing and leaf beating during the current lettuce growth process, and meet the demand of replacing manual labor.

[0006] The technical solution adopted by the present invention to solve the technical problem is as follows: the lettuce growth management machine comprises a movable frame, a growth management mechanism and a control system are arranged on the frame, the control system controls the growth management mechanism through a control circuit, the growth management mechanism comprises a loosening device, a leaf beating device, a fertilizing device and an irrigation device from front to back, the loosening device comprises a loosening wheel for rotating loosening, and the loosening wheel is provided with loosening blades for loosening the soil near the root system. After such arrangement, the loosening machine device utilizes the loosening wheel to drive the loosening blades to rotate so that the loosening blades penetrate into the soil and stir, and can effectively perform rotary loosening, and can also utilize the adjustment of the rotation speed of the loosening machine to adapt to land of different ecology and soil quality, so as to make the soil more breathable.

[0007] The fertilization device includes a fertilizer storage box fixed on a frame, an outlet end is provided at the bottom of the fertilizer storage box and is connected to a retractable and deformable discharge pipe, the outlet end of the discharge pipe is connected to the frame by moving forward and backward, and the control system is connected to a first sensor fixed on the frame to detect lettuce, and the control system confirms the position of the lettuce through the first sensor and controls the outlet end of the discharge pipe to move toward the position of the lettuce to apply fertilizer. After such a setting, the lettuce may have different plant spacings due to planting and other reasons, making accurate fertilization more difficult, and the fertilization device can solve the problem of accurate positioning according to the properties of different fertilizers, such as decomposed fertilizer, nitrogen fertilizer, potash fertilizer, and wood ash, and the control system determines the position of the lettuce through the first sensor, and solves the problem of accurate positioning, so that the outlet end of the discharge pipe can be accurately sown according to the position of the lettuce. This design can effectively improve the efficiency and accuracy of fertilization, reduce the situation of excessive or insufficient fertilization, and thus improve the yield and quality of crops.

[0008] The irrigation device includes a water tank for storing water and a water pump for pumping water. The water outlet of the water pump is connected to a spraying end, and the spraying end is located above the lettuce to form a top-down whole-plant irrigation structure. After this arrangement, the water pump draws water from the water tank and releases it through the spraying end. The roots of the lettuce itself are very shallow and fragile, and water cannot be sprayed directly on the roots. Too much water cannot be absorbed by the lettuce, otherwise water will accumulate and affect the growth of the lettuce. However, watering must ensure that the soil is moist, so the top irrigation method is adopted to allow the roots of the lettuce to fully absorb water. The specific plan is to place the spraying end above the lettuce to achieve top-down whole-plant irrigation, and use water to slowly penetrate into the soil.

[0009] The beating device includes a beating blade that can adaptively clamp the lettuce left and right. The beating blade is connected to the frame in a lifting manner. The clamping surface of the beating blade becomes the beating end surface for peeling off the lettuce leaves when it clamps and embraces the lettuce and moves up and down. After such arrangement, the beating blade can adaptively clamp and embrace the lettuce left and right according to the size of the lettuce and move up and down at the same time to peel off the lettuce leaves using the beating end surface, so that the beating can be done quickly and the efficiency can be rapidly improved.

[0010] As a further improvement of the present invention, the loosening blades are radially distributed on the loosening wheel and are tilted outwardly, so that a rotating loosening area is formed outside the loosening wheel. After such arrangement, the loosening blades are radially spread to improve the loosening efficiency, and the loosening blades are tilted outwardly to limit the loosening area to the outside of the loosening wheel, thereby avoiding a large amount of soil from being brought into the equipment to cause pollution and damage, and playing a certain protective role.

[0011] As a further improvement of the present invention, a feeding wheel placed horizontally on the feeding path is rotatably connected to the bottom outlet of the fertilizer storage box, and grooves for receiving the lowered fertilizer are evenly arranged on the circumference of the feeding wheel. The grooves cooperate with the feeding wheel to rotate at a uniform speed during feeding to form a timed and quantitative fertilizer feeding structure. After such arrangement, there is a feeding wheel with rotating motion in the outlet of the fertilizer storage box. When the feeding wheel rotates, the fertilizer discharged from the fertilizer storage box first enters the groove of the feeding wheel, and then the groove flips after the feeding wheel rotates to release the fertilizer. The timed and quantitative management of fertilizer spreading can be realized during the rotation of the feeding wheel.

[0012] As a further improvement of the present invention, the beating device includes a horizontally placed electric cylinder, the beating blade is a sheet structure made of an elastic material with an arc, the beating blade is rotatably connected to the moving end of the electric cylinder, and a spring is connected between the beating blade and the moving rod of the electric cylinder, the rotating connection between the beating blade and the moving end of the electric cylinder is respectively located on both sides of the lettuce and are horizontally staggered, and the beating blade relies on the spring elasticity and the arc structure of the beating blade to form an adaptive clamping structure that embraces the lettuce when clamping. After such a setting, when the beating blades on both sides move toward and clamp the lettuce in the middle, since the rotating connection between the beating blade and the moving end of the electric cylinder is respectively located on both sides of the lettuce and are horizontally staggered, the beating blade will first rotate to clamp the lettuce, and then rotate under the pressure of the spring to cooperate with the arc of the beating blade itself to achieve an adaptive clamping and embracing effect of the lettuce, meeting the clamping requirements of the beating blade.

[0013] As a further improvement of the present invention, the frame includes a top connecting frame, a left movable frame, a middle fixed frame and a right movable frame, the middle fixed frame is fixedly connected to the middle position of the bottom of the top connecting frame, the left movable frame and the right movable frame are respectively located on the left and right sides of the middle fixed frame and are connected to the bottom of the top connecting frame with the middle fixed frame as the center, and the left movable frame and the middle fixed frame, and the middle fixed frame and the right movable frame are between a channel structure with an adjustable width for the lettuce planting area to pass through. After being set in this way, the frame is composed of the top connecting frame, the left movable frame, the middle fixed frame and the right movable frame, and the left movable frame and the middle fixed frame, and the middle fixed frame and the right movable frame are between a channel structure with an adjustable width for the lettuce planting area to pass through, so that the machine can move along the lettuce planting area and complete the watering, fertilizing and leaf beating operations during the advancement.

[0014] As a further improvement of the present invention, a distance adjustment mechanism connected to the control system is provided on the frame, and the distance adjustment mechanism includes a sliding connection structure between the left movable frame and the right movable frame and the middle fixed frame respectively through a movable slider and a slide rail, and a driving motor is provided on the left movable frame and the right movable frame. The outer ends of the left movable frame and the right movable frame are connected with universal wheels, and the driving motor is connected to the corresponding movable slider through a screw rod to cooperate with the universal wheels that can be turned at will to form a width adjustable structure between the left movable frame and the right movable frame with respect to the middle fixed frame. After such arrangement, the row spacing adjustment mechanism can adjust the distance between the left movable frame and the right movable frame relative to the middle fixed frame, and realize the adjustment of the width of the left and right channels to adapt to planting areas of different widths, so as to avoid the situation where the use is limited due to the width of the planting area, and the adaptability range is wider. The row spacing adjustment mechanism can be controlled and adjusted by the control system, and the adjustment is fast and easy.

[0015] As a further improvement of the present invention, a moving block that moves along the moving direction of the frame is slidably connected to the middle fixed frame, the outlet end of the discharge pipe is fixed on the moving block, and the mobile block controls the access control system to form a mobile structure that accurately reaches the fertilization position. After such a setting, the moving block is used to drive the outlet end of the discharge pipe to move. When the control system cooperates with the first sensor to locate the lettuce position, the moving block sends the outlet end of the discharge pipe to the vicinity of the lettuce root for fertilization, which greatly improves the fertilization efficiency and accuracy.

[0016] As a further improvement of the present invention, the bottom end of the beating blade is a serrated structure. After such arrangement, the serrated structure at the bottom end of the beating blade can better and faster peel off the residual lettuce leaves, thereby improving the beating efficiency.

[0017] As a further improvement of the present invention, the spraying end is fixed on the top of the frame and directly facing the lettuce growing area, and the spraying end is an atomizing spraying end.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings:

[0029] Referring to the accompanying drawings: the lettuce growth management machine in the present embodiment comprises a movable frame, a growth management mechanism and a control system are arranged on the frame, the control system controls the growth management mechanism through a control circuit, the growth management mechanism comprises a loosening device, a leaf beating device, a fertilizing device and an irrigation device from front to back, the loosening device comprises a loosening wheel 1 for rotating loosening, and the loosening wheel 1 is provided with loosening blades 1-1 for loosening the soil near the root system. In the scheme, a variable speed motor is used as the power of the loosening wheel 1. The rated speed of the motor is 500r / min, and the speed is adjusted to a suitable speed of 160-260r / min. The motor is used to transmit the power generated by the rotation to the loosening wheel to drive the loosening blades to realize the loosening function. After the fertilizer is loaded, the device has a certain weight enough to allow the loosening blade wheel to sink into the soil. The loosening wheel is driven by the motor to rotate to loosen the soil, so that the loosening effect is better. On the other hand, the loosening wheel is rotated in the opposite direction of the device to loosen the soil, which can greatly improve the loosening effect.

[0030] The fertilization device includes a fertilizer storage box 2 fixed on a frame, an outlet end is provided at the bottom of the fertilizer storage box 2 and connected to a retractable and deformable discharge pipe 3, the outlet end of the discharge pipe 3 is connected to the frame by moving forward and backward, and the control system is connected to a first sensor fixed on the frame to detect lettuce, and the control system confirms the position of the lettuce through the first sensor and controls the outlet end of the discharge pipe 3 to move toward the position of the lettuce to apply fertilizer. Since the fertilizer storage box 2 stores various fertilizers, there is a discharge pipe 3 under the storage box, and the fertilizer will flow out quantitatively along the discharge pipe 3 by gravity. At the same time, because the front and rear spacing of lettuce may be different, in order to prevent the situation that some fertilizers cannot be sprinkled around the lettuce due to the fixed fertilization position, the control system in the scheme judges the position of the lettuce through the first sensor, controls the outlet end of the discharge pipe 3 to be close to the root of the lettuce and then applies fertilizer, so as to achieve precise fertilization.

[0031] The irrigation device includes a water tank 4 for storing water and a water pump for pumping water. The water outlet of the water pump is connected to a spraying end 16. The spraying end 16 is located above the lettuce to form a whole-plant irrigation structure from top to bottom. The roots of the lettuce itself are shallow and fragile. Excessive watering can easily affect the growth of the lettuce. It is not possible to spray water directly on the roots, so we use spraying from above to allow the roots of the lettuce to fully absorb water. In the scheme, water is drawn from the water tank by a water pump and then irrigated from above through the spraying end 16. At the same time, the water tank can also be filled with pesticides, and the function of spraying pesticides can also be realized.

[0032] The beating device comprises a beating blade 5 for clamping the lettuce adaptively on the left and right sides, the beating blade 5 is connected to the frame by lifting, and the clamping surface of the beating blade 5 becomes the beating end surface for peeling the lettuce leaves when clamping and hugging the lettuce and moving up and down. Preferably, the bottom end of the beating blade 5 is a serrated structure.

[0033] The loosening blades 1 - 1 are distributed in a circumferential radial pattern on the loosening wheel 1 and are arranged to be inclined outward, so that a rotating loosening area is formed outside the loosening wheel 1 .

[0034] A discharge wheel 6 is rotatably connected to the bottom outlet end of the fertilizer storage box 2 and is horizontally placed on the discharge path. Grooves for receiving the discharged fertilizer are evenly arranged on the circumference of the discharge wheel 6. When discharging, the grooves cooperate with the discharge wheel 6 to rotate at a uniform speed to form a timed and quantitative fertilizer discharging structure.

[0035] The beating device includes a horizontal electric cylinder 7, and the beating blade 5 is a sheet structure made of an elastic material with an arc. The beating blade 5 is rotatably connected to the moving end of the electric cylinder 7, and a spring 8 is connected between the beating blade 5 and the moving rod of the electric cylinder 7. The rotating connection between the beating blade 5 and the moving end of the electric cylinder 7 is respectively located on both sides of the lettuce and is horizontally staggered. When the beating blade 5 is clamped, the elasticity of the spring 8 and the arc structure of the beating blade 5 form an adaptive clamping structure that surrounds the lettuce, as shown in the attached figure. Figure 6 The beating blades are made of soft material with barbed texture on the surface, which increases the friction and ensures the peeling effect of the lettuce. At the same time, it is not easy to damage the lettuce body and avoid unnecessary losses.

[0036] The frame includes a top connecting frame 9, a left movable frame 10, a middle fixed frame 11 and a right movable frame 12. The middle fixed frame 11 is fixedly connected to the middle position of the bottom of the top connecting frame 9.

The driving motor is connected to the corresponding movable slider 13 through a screw rod and cooperates with the universal wheel that can be turned at will to form an adjustable width structure between the left movable frame 10 and the right movable frame 12 and the middle fixed frame 11.

[0038] A moving block 14 that moves along the moving direction of the frame is slidably connected to the middle fixed frame 11, and the outlet end of the discharge pipe 3 is fixed on the moving block 14. The moving block 14 controls the access control system to form a mobile structure that can accurately reach the fertilization position.
