Technical Field

[0001] The utility model relates to the technical field of seedling cultivation, in particular to a seedling raising frame with adjustable layer height. Background Art

[0002] A seedling rack is a support system used to grow seedlings or seeds. It usually includes one or more devices that can provide the necessary conditions for plant growth, such as light, temperature and humidity control devices. Seedling racks can be used indoors or outdoors to provide growers with a controlled environment to help seeds germinate and seedlings grow. This equipment is widely used in agriculture, horticulture and plant breeding.

[0003] The upper and lower placement boards of the existing seedling rack are fixedly installed on the rack, so that the layer height cannot be adjusted. When the seedlings grow to a certain height, the seedling heads will hit the upper placement board, thereby affecting the growth of the seedlings. Therefore, a seedling rack with adjustable layer height is needed to improve the above problem. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Example: See Figure 1-3 The seedling rack with adjustable layer height shown in the figure comprises a lower fixed plate 1, a vertical pole 2 is installed at the end corner of the lower fixed plate 1, a first sliding sleeve 3 is slidably connected to the outer wall of the vertical pole 2, four first sliding sleeves 3 are connected through a first movable plate 4, a second sliding sleeve 5 is slidably connected to the outer wall of the vertical pole 2 and located above the first sliding sleeve 3, four second sliding sleeves 5 are connected through a second movable plate 6, a through hole 7 is opened on the lower fixed plate 1 and the first movable plate 4, a lifting structure 8 is installed on the lower fixed plate 1 and the first movable plate 4, the lifting structure 8 comprises a transmission shaft 801, connecting rods 802 are installed on the outer walls of the front and rear sides of the transmission shaft 801, a short pin 803 is installed on the side wall of the other end of the connecting rod 802, a support rod 804 is rotatably connected to the outer wall of the short pin 803, and the other end of the support rod 804 One end is rotatably connected with a long pin 805 through a connecting hole, and an L-shaped plate 806 is installed on the side walls of the lower fixed plate 1 and the first movable plate 4, and an axis locker 807 is installed on the side wall of the L-shaped plate 806. The upper ends of the four vertical rods 2 are connected through the upper fixed plate 9, and the crank 809 in the assembly is used to drive the transmission shaft 801 to rotate forward, and the transmission shaft 801 drives the two connecting rods 802 to move upward. Through the cooperation of the connecting rod 802, the short pin 803, the support rod 804 and the long pin 805, the long pin 805 drives the placement plate connected to it to move upward, thereby increasing the layer height of the seedling rack. By setting the lifting structure 8, the problem that the layer height of the existing seedling rack cannot be adjusted is solved, and the situation that the upper placement plate is hit during the growth of the seedlings is avoided, which helps the seedlings to grow taller.

[0020] In this embodiment, refer to Figure 1-3 As shown, the lower fixed plate 1 and the first movable plate 4 are rotatably connected to the transmission shaft 801 through the through hole 7 respectively; the other ends of the two long pins 805 on the lower side are fixedly connected to the first movable plate 4, and the other ends of the two long pins 805 on the upper side are fixedly connected to the second movable plate 6; a support column 10 is installed at the bottom corner of the lower fixed plate 1, and a walking wheel 11 is provided at the lower end of the support column 10, and the walking wheel 11 is a lockable universal wheel; the walking wheel 11 is a lockable universal wheel, which is convenient for moving the seedling rack, and the seedling rack can be locked when it is parked;

[0021] In this embodiment, refer to Figure 1 and 2As shown, the vertical rod 2 and the lower fixed plate 1 are arranged perpendicular to each other, and the lower fixed plate 1, the first sliding sleeve 3, the second movable plate 6 and the upper fixed plate 9 are arranged parallel to each other in pairs; a limit block 808 is arranged at one end of the short pin 803 and the long pin 805, and a crank 809 is arranged at one end of the transmission shaft 801, and the limit block 808 is a disc-shaped structure; by arranging the limit block 808 at one end of the short pin 803 and the long pin 805, the positions of the two ends of the support rod 804 can be limited to prevent the support rod 804 from being out of control and causing the lifting structure 8 to fail to operate;

[0022] Working principle: When the seedling rack with adjustable layer height is in use, the user turns the crank 809 forward, and the crank 809 moves the two connecting rods 802 upward. The connecting rod 802 moves the support rod 804 upward under the transmission action of the short pin 803, and the support rod 804 drives the long pin 805 to move, and the support rod 804 rotates on the outer wall of the long pin 805. In this scheme, the two long pins 805 on the lower side drive the first movable plate 4 to move upward, and the two long pins 805 on the upper side drive the second movable plate 6 to move, which can increase the layer height of the seedling rack; the crank 809 drives the transmission shaft 801 to rotate in the opposite direction, which is opposite to the above-mentioned step of increasing the layer height, and can reduce the layer height. By setting the lifting structure 8, the problem that the layer height of the existing seedling rack cannot be adjusted is solved, and the situation that the seedlings hit the upper placement plate during the growth process is avoided, which is helpful for the seedlings to grow taller.
