Detailed Implementation

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1 , Figure 2 As shown, an automated harvesting device for hydroponic barley grass is installed inside a hydroponic container 1. In this invention, the hydroponic container can be a greenhouse or nursery, or it can be a container structure, such as a mobile shipping container. This invention is illustrated using a shipping container as the hydroponic container. It includes a material transfer mechanism located near the bottom of the hydroponic container 1. The transfer mechanism's conveying direction is along the length of the hydroponic container 1, and it is used to collect and transport the mature barley grass. Preferably, the material transfer mechanism is located at the center line of the bottom of the hydroponic container 1, dividing the internal space of the hydroponic container into two symmetrical spaces. A support 2 is installed in each space of the hydroponic container 1, with the end of the support 2 adjacent to the material transfer mechanism designated as the front end, and the end of the support 2 away from the material transfer mechanism designated as the rear end. The support 2 is arranged with several layers of seedling areas from top to bottom. Each layer of seedling area has several seedling trays 4 arranged side by side along the conveying direction of the transfer mechanism. Similarly, the end of each seedling tray 4 closest to the transfer mechanism is the front end, and the end furthest from the transfer mechanism is the rear end. The front end of the seedling tray 4 is hinged to the support 2 through the hinge shaft 7. The rear end of the bottom surface of the seedling tray 4 is hinged to the lifting element 3 through the hinge pin 31. The lifting element 3 is hinged to the support 2. The lifting element 3 is preferably a cylinder.

[0034] The material moving mechanism can be a conveying belt or a movable collecting barrel 10. If the material moving mechanism is a conveying belt, the terminal of the conveying belt corresponds to the position of the door 101 of the container, and the conveying belt can transport the collected barley straw to the position of the door 101 of the container, so as to facilitate subsequent transfer of the barley straw to other processing equipment, such as a crushing and stirring device, for further processing. The material moving mechanism shown in the figure is a collecting barrel 10, which is preferably a square barrel with a height lower than the height of the lowermost layer of the seedling tray 4.

[0035] A spraying pipe 8 is arranged at each layer of the seedling area and is horizontally arranged at a position directly above the seedling tray 4 of the seedling area. In the utility model, the spraying pipe 8 is arranged along the conveying direction of the material moving mechanism. The spraying pipe 8 is connected to a water tank 11 through a pump (not shown in the figure), and the spraying pipe 8 is provided with a plurality of spraying nozzles facing the seedling tray 4. The water tank 11 stores water for water culture of the barley straw, and the water is sprayed to the barley seeds and the barley after germination in the seedling tray 4 through the spraying pipe 8 and the spraying nozzles, so as to supply water for growth. The structure is a commonly used water supply structure for water culture of seedlings, and will not be described in detail here.

[0036] In the utility model, the seedling tray 4 can be flipped around the hinge shaft 7 under the action of the lifting element 3, so that the seedling tray 4 is in an inclined state with the front end being low and the rear end being high. After the barley in the seedling tray 4 grows, the seedling tray 4 is flipped, and the barley in the seedling tray 4 can automatically slide to the material moving mechanism under the action of gravity, and then is transported out by the material moving mechanism, so as to realize automatic harvesting of the barley.

[0037] A rotating shaft 6 is arranged at each layer of the seedling area and is arranged at a position in the upper front part (the side close to the material moving mechanism) of the seedling area. The rotating shaft 6 is arranged in the same direction as the conveying direction of the material moving mechanism, is installed on the support 2 and is driven to rotate by the motor 9. A plurality of material pushing mechanisms 5 are arranged at the rotating shaft 6 of each layer of the seedling area. The number of the material pushing mechanisms 5 is the same as the number of the seedling trays 4 of the seedling area and corresponds to the seedling trays 4 one by one. As shown in Figure 3 The material pushing mechanisms 5 can push the barley on the corresponding seedling trays 4 out. The specific structure of the material pushing mechanism 5 is shown in Figure 4As shown, it comprises a pushing element 51, a pushing plate 52 and a baffle 54. The pushing element 51 is preferably a cylinder which is mounted on a cylinder seat, and the cylinder seat is welded on the rotating shaft 6 to realize the connection and fixation of the pushing element 51 and the rotating shaft 6. The pushing rod of the pushing element 51 is arranged horizontally and rearwardly (towards the rear end of the seedling tray). The pushing plate 52 is mounted on the pushing rod of the pushing element 51, and the pushing plate 52 is provided with a plurality of poking rods 53 corresponding to the seedling tray 4. The front end of each poking rod 53 is preferably conical to facilitate the insertion into the root system of the barley grass. The plurality of poking rods 53 are uniformly arranged along the direction of the rotating shaft 6. The baffle 54 is arranged outside the pushing plate 52, i.e. on the side of the pushing plate 52 which is away from the rotating shaft 5. The baffle 54 is connected and fixed with the rotating shaft 6 through the connecting plates at both ends, and the baffle 54 is provided with through holes corresponding to the poking rods 53. When the pushing rod of the pushing element 51 is retracted, the front end of the poking rod 53 is retracted into the corresponding through hole, as shown in Figure 4 When the pushing rod of the pushing element 51 is extended, the front end of the poking rod 53 is extended from the corresponding through hole, as shown in Figure 5

[0038] After the barley grass grows in the seedling tray 4, the root system of the barley grass will be entangled and tightly wound together, and at this time, the root system of the barley grass forms a carpet-like structure, so that the barley grass in the seedling tray 4 forms an integral structure. The arrangement of the poking mechanism 5 facilitates the poking and carrying of the barley grass out of the seedling tray. The working principle is shown in Figure 7 When the seedling tray 4 is tilted to the unloading state under the action of the lifting element 3, the motor drives the rotating shaft 6 to rotate, thereby driving the poking mechanism 5 to rotate to the position directly opposite to the seedling tray 4. The pushing rod of the pushing element 51 is extended, thereby driving the poking rod 53 to extend from the corresponding through hole and insert into the root system of the barley grass in the seedling tray 4. The rotating shaft 6 drives the poking mechanism 5 to continue to rotate, and the poking rod 53 carries part of the barley grass in the seedling tray 4 out of the seedling tray. Then, the pushing rod of the pushing element 51 is retracted, and the poking rod 53 is retracted into the through hole of the baffle 54. The baffle 54 pushes and unloads the root system of the barley grass inserted on the poking rod 53. Since the seedling tray 4 is in the tilted state, the whole barley grass slides out of the seedling tray under the action of gravity and falls into the collecting barrel 10 for collection, thereby realizing the automatic harvesting of the barley grass. After the collection of the barley grass in one seedling tray 4 is completed, the seedling tray 4 is reset, the rotating shaft 6 is reversely rotated to reset, the collecting barrel 19 is moved to the position of the next seedling tray, and the harvesting of the barley grass in the next seedling tray is carried out.

[0039] ​If the material moving mechanism is a conveying belt, the barley grass in all the seedling trays of each layer can be harvested at the same time, and the barley grass falls on the conveying belt and is output by the conveying belt. If the material moving mechanism is the collecting barrel 10, the barley grass in the seedling trays of the same layer is harvested one by one, so the harvesting operation of the barley grass in the same layer needs to be operated several times to complete, only the roots of the barley grass in the seedling trays are wound together, the stems of the barley grass are independent of each other and have high flexibility, only the corresponding one of the material moving mechanisms 5 on the rotating shaft 6 operates each time the barley grass is harvested, and only the barley grass to be harvested in the inclined seedling tray 4 is operated, so even if the other material moving mechanisms 5 rotate with the rotating shaft, the growth state of the barley grass in the other seedling trays will not be affected.

[0040] In the utility model, the structure of the seedling tray 4 is as shown in Figure 6 The seedling tray 4 is a square tray, the front side wall 41, that is, the side wall close to the material moving mechanism, is an inclined wall with the top end close to the front and the bottom end close to the back. The structure is convenient for the grown barley grass to slide off. At the same time, the left and right side walls of the seedling tray 4 are respectively provided with a plurality of overflow holes 42, and the overflow holes 42 are away from the bottom of the seedling tray 4. The water collecting groove can be arranged at the lowest end of the support 2 of the water culture box 1, which is not shown in the drawing, and is used for collecting the overflow water of the seedling tray 4 to maintain a clean environment in the water culture box.

[0041] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
