Description

Technical Field

[0001] This utility model relates to the field of agricultural cultivation equipment technology, specifically a self-cleaning strawberry planting lifting mechanism with a guide channel. Background Technology

[0002] Strawberries are widely cultivated due to their high nutritional value and good economic benefits. Traditional strawberry cultivation mostly uses ground-level seedbed planting, which not only requires a large area and has low space utilization, but also makes the plants susceptible to pests and diseases and soil pollution due to their constant proximity to the ground, leading to increased pesticide use. This is not in line with the development trend of modern green agriculture. To solve these problems, vertical cultivation technology has emerged, among which the lifting cultivation rack has attracted attention because it can flexibly adjust the plant's lighting position and facilitates management and harvesting.

[0003] However, existing lifting cultivation devices still have many shortcomings: First, irrigation and fertilization mostly use ordinary drip irrigation or sprinkler systems, which easily cause water and fertilizer to splash out. Furthermore, the residual withered leaves, rotten fruits, and substrate particles in the cultivation trough cannot be effectively cleaned. Over time, these impurities accumulate, breeding bacteria and clogging pipes, seriously affecting crop growth and the lifespan of the device. Second, the drainage system of existing devices is simply designed, mostly with straight discharge or simple sloping troughs. Poor drainage can easily cause water to backflow and contaminate the lower plants. Third, current lifting mechanisms mostly use motors in conjunction with steel wire ropes or chains for traction, resulting in poor operational stability and positioning accuracy, posing safety hazards.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1-5 As shown, the self-cleaning strawberry planting lifting mechanism with guide channels includes:

[0032] Base frame 1;

[0033] Two vertical columns 2 are fixedly installed at their bottom ends on the base frame 1;

[0034] A horizontal beam 3 is slidably connected at both ends to two vertical columns 2 via linear sliders 4;

[0035] One or more planting trough units 5, the frames of which are fixedly installed on the horizontal beam 3;

[0036] The V-shaped guide channel bottom plate 6 has one long side that is rotatably connected to the bottom edge of the planting trough unit 5 frame via a hinge 7;

[0037] Drainage outlet 8 is located at the lowest point of the inclined surface of the V-shaped guide channel bottom plate 6;

[0038] The electric push rod 9 has its cylinder body hinged to the base frame 1, and its push rod end hinged to the bottom of the horizontal beam 3, which is used to drive the horizontal beam 3 to rise and fall along the vertical column 2.

[0039] The high-pressure spray pipe 10 is fixedly installed above the horizontal beam 3 by the support frame 11 and is located directly above the opening of the planting trough unit 5.

[0040] The central controller 12 is fixedly installed on the base frame 1 or on the external wall. Its output end is electrically connected to and controls the solenoid valve of the electric push rod 9 and the high-pressure spray pipe 10 via a cable. Its input end is electrically connected to a sensor used to detect environmental parameters.

[0041] A filter assembly 13 is detachably connected inside the drain outlet 8. The filter assembly 13 is connected to the inner wall of the drain outlet 8 by threads to prevent solid impurities such as planting substrate (such as soil, coconut coir), dead leaves, and rotten fruit from entering the drainage pipe, thus avoiding pipe blockage.

[0042] The filter assembly 13 is equipped with a rotating scraper 15 driven by a micro motor 14. The power and control lines of the micro motor 14 pass through the side wall of the drain outlet 8 and are electrically connected to the central controller 12, which realizes the self-cleaning function of the filter and solves the core problem that the filter itself is clogged with impurities and affects the drainage efficiency.

[0043] A sealing strip 16 is provided at the contact edge between the bottom plate 6 of the V-shaped guide channel and the frame of the planting trough unit 5. The sealing strip 16 is adhered to the sealing groove at the bottom of the frame to ensure that wastewater will not leak from the joint during the rinsing operation.

[0044] The end of the electric linear actuator 9 is connected to the horizontal beam 3 by a universal joint 17, which eliminates the problem of different axiality caused by machining, installation errors or frame deformation, and avoids the electric linear actuator 9 bearing additional radial force (lateral force).

[0045] The sensors include a light sensor 18 and a substrate moisture sensor 19. The light sensor 18 is installed at the end of the horizontal beam 3, and the probe of the substrate moisture sensor 19 extends into the substrate of the planting trough unit 5, providing a reliable data basis for the intelligent decision-making of the central controller 12, thereby realizing closed-loop intelligent control.

[0046] One or more hooks 20 are installed on the side of the V-shaped guide channel bottom plate 6 opposite to the hinge, and a locking ring 21 is installed on the corresponding position of the planting trough unit 5 frame to lock the V-shaped guide channel bottom plate 6 and the planting trough 5.

[0047] The mechanism comprises multiple planting trough units 5, which are fixedly installed side by side on the same horizontal beam 3, improving the efficiency of a single operation (multiple troughs can be handled in one lifting or cleaning operation).

[0048] The working principle of this utility model is as follows:

[0049] The central controller 12 receives environmental data collected in real time from the light sensor 18 and the substrate moisture sensor 19. When the light needs to be adjusted, the controller controls the electric push rod 9 to work. The push rod smoothly pushes or pulls the horizontal beam 3 through the universal joint 17, which drives all planting trough units 5 to rise and fall to the appropriate height along the linear slider 4 on the vertical column 2. When insufficient substrate moisture is detected, the controller opens the solenoid valve of the high-pressure spray pipe 10 for precise irrigation. In self-cleaning mode, the controller first lowers the planting trough to a suitable height, then activates the high-pressure spray pipe 10 to flush away dirt in the trough with high water pressure. Wastewater and impurities flow along the bottom plate 6 of the V-shaped guide channel to the drain outlet 8, and are discharged after being filtered by the filter assembly 13. During the process, the controller can periodically activate the micro motor 14 to drive the rotating scraper 15 to rotate. The micro motor 14 is fixed to the side wall of the filter assembly 13 by the motor frame to remove the blockages attached to the filter screen. The sealing strip 16 effectively prevents wastewater from leaking from the joints. When cleaning or maintenance is required, the hook 20 is manually released from the locking ring 21, and the bottom plate 6 of the V-shaped guide channel can rotate and hang down around the hinge 7. After completion, it is raised to a horizontal position and the hook 20 is hung up. This achieves integrated operation of lifting adjustment, intelligent irrigation and efficient self-cleaning.
