The bearings are installed at the tops of the two opposite vertical steel plates 10, the directions of the two opposite transverse steel plates 11 are opposite, and the rotating shaft 3 is installed between the two vertical steel plates 10 through the bearings.
The simple pendulum frame 7 is fixed on the rotating shaft 3 through a key, the whole simple pendulum frame 3 is of an inverted V-shaped structure, and any one side of the simple pendulum frame 3 can be regarded as a common seedling tray. A rotating part 8 is installed at the tail end of a cylinder 41 of the cylinder assembly, the rotating part 8 is installed at the tail end of the transverse steel plate 11 through the stepped shaft 2, one end of a piston rod 42 of the cylinder assembly is fixed on the fixing part 6 through a round nut 5, and the fixing part 6 is fixed in the middle of a frame body of the simple pendulum frame 7.
When the seedling feeding simple pendulum machine is in a static state, the simple pendulum machine frame 7 in the inverted V-shaped structure is static in the middle of the whole machine frame, the gravity center of the seedling feeding simple pendulum machine is located on the vertical extension line of the rotating shaft 3, and the seedling feeding simple pendulum machine is in axial symmetry by taking the rotating shaft 3 as a symmetry axis.
The inverted-V-shaped structure of the embodiment 1 adopts the working mode of the seedling taking and feeding simple pendulum machine:
seedling is arranged on the two face plates of the single pendulum machine frame 7 according to the sequence, the moving time point of the air cylinder is set, the time point of seedling discharging just enables the piston rod of one air cylinder assembly to extend to the longest, namely, one side face seedling plate of the single pendulum machine frame 7 is located at the lowest position, when seedling discharging is conducted, the damage to the seedling is the smallest, and the other side face seedling plate of the single pendulum machine frame 7 is located at the highest position.
The left cylinder component and the right cylinder component reciprocate alternately, so that the simple pendulum frame 7 reciprocates by taking the rotating shaft 3 as the center of a circle and the vertical line in the vertical direction as an axis to form similar simple pendulum motion.
The simple pendulum machine frame 7 is named after the simple pendulum motion, and the shape of the simple pendulum machine frame is an inverted V-shaped symmetrical structure. The preferred design angle is 40 °.
Example 2 differs from example 1 in that the pendulum frame 7 is two separate seedling tray frames independently mounted on the rotating shaft, and the rest is the same as in the example.
The specific working process of embodiment 1 or embodiment 2 of the present invention:
seedling is arranged on two face plates of the single pendulum machine frame according to a sequence respectively, the time point of cylinder movement is set, the time point of seedling discharging just enables a piston rod of one cylinder assembly to extend to the longest, namely, a side face seedling plate of the single pendulum machine frame is located at the lowest position, when seedling discharging is conducted, the damage to the seedling is the smallest, and the seedling plate on the other side of the single pendulum machine frame is located at the highest position. At this time, the piston rod of the cylinder assembly on one side is also extended to the longest and inserted into the seedling placed in the seedling tray. And after the seedlings are successfully fed from one side of the simple pendulum frame and the seedlings are successfully picked from the other side of the simple pendulum frame, the simple pendulum frame starts to return to the original path. At the moment, one side with the seedlings is at the lowest position to facilitate the seedling discharging, and the other side without the seedlings is at the highest position to facilitate the seedling taking. And returning the path after finishing the corresponding action. This is repeated.
The first characteristic of the invention is that the seedling taking at two ends of the single pendulum frame overcomes the efficiency problem.
The second characteristic is that the simple pendulum frame symmetrically solves the problem that the center of gravity is not stable when the former frame runs.
Referring to fig. 3 and 4, it can be seen that the height of the center of gravity of the single pendulum frame is only about half of that of the common frame when the two frames are at the same angle. When the two racks form an angle of 40 degrees with the horizontal plane, the gravity center of the simple pendulum rack is only 20 degrees, while the gravity center of the common rack is 45.7 degrees.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
