[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Example 1
[0020] Reference Figure 1-4A seedling pressing device for grain planting comprises a base 1, wherein first pressing rollers 2 are arranged on both sides of one side of the bottom of the base 1, a second pressing roller 3 is arranged on the other side of the bottom of the base 1, a driving assembly is arranged between the two first pressing rollers 2 and the base 1, a rotating mechanism is arranged between the second pressing roller 3 and the base 1, a weight block 4 is arranged in the middle of the bottom of the base 1, a connecting mechanism is arranged between the weight block 4 and the base 1, the connecting mechanism comprises a moving block 5 arranged at the bottom of the base 1, a moving mechanism is arranged between the moving block 5 and the base 1, a fixing frame 6 is installed at the bottom of the moving block 5, the weight block 4 is slidably arranged in the fixing frame 6, a motor 7 is installed on the fixing frame 6, a first threaded rod 8 is installed on the output shaft of the motor 7, one end of the first threaded rod 8 is threadedly connected to the weight block 4, the moving mechanism comprises a groove 9 opened on one side of the base 1, one end of the moving block 5 is slidably arranged in the groove 9, a second threaded rod 10 is installed in the groove 9 by bolts, and the second threaded rod 10 threadably penetrates the moving block 5 in the groove 9.
[0021] Combined with Figure 1-4 It can be seen that two support columns are arranged at the bottom of the base 1, and the two first pressure rollers 2 are installed on the support columns through bearings. A transmission shaft is arranged between the two first pressure rollers 2, and the rotating shaft is connected to the driving assembly on the base 1, so that the two first pressure rollers 2 can rotate, and the driving assembly is connected to the second threaded rod 10, so that the second threaded rod 10 can rotate; a rotating shaft is installed on the base 1 through a bearing, a support frame is installed at the bottom of the rotating shaft, a second pressure roller 3 is installed on the support frame, and a handle is installed at one end of the rotating shaft, so that the second pressure roller 3 is responsible for steering. Therefore, in the utility model, the second pressure roller 3 is a steering roller, and the two first pressure rollers 2 are driving rollers, so that the base 1 can be steered during the movement.
[0022] When the operator is on the base 1 and operates the device through the handle, the operator controls the driving assembly through the external control switch, so that the second threaded rod 10 rotates. During the rotation of the second threaded rod 10, the moving block 5 is moved with it, so that the position of the weight block 4 can be adjusted, so that the center of gravity of the device is shifted, and then the driving assembly is rotated with the two first pressing rollers 2, so that the device can press the grain seedlings, so that the device is not prone to tipping over front and back during the process of pressing the grain seedlings; and when the device needs to turn, the motor 7 is controlled by the external control switch, so that the output shaft of the motor 7 rotates with the first threaded rod 8, so that the weight block 4 extends out of the fixed frame 6 and is pressed on the ground, so that the pressing force of the second pressing roller 3 on the ground is reduced, so that the second pressing roller 3 can be turned significantly, making it easier for the device to turn.
[0023] Example 2
[0024] In Example 1, the fixed frame 6, the weight block 4, the motor 7, and the first threaded rod 8 exert a relatively large gravity on the moving block 5, so that the connection between the moving block 5 and the fixed frame 6 is very easy to break. Based on Example 1, the optimization is performed, and reference is made to Figure 1-4 A reinforcement mechanism is provided between the fixing frame 6 and the base 1 , and the reinforcement mechanism includes a slot 11 opened on one side of the base 1 , a reinforcement rod 12 is slidably provided on the slot 11 , and one end of the reinforcement rod 12 is installed on one side of the fixing frame 6 .
[0025] By using the reinforcing rod 12 and the slot 11 , the reinforcing rod 12 can share the gravity, thereby reducing the gravity on the moving block 5 , thereby reducing the probability of fracture at the connection between the moving block 5 and the fixing frame 6 .
[0026] Example 3
[0027] Based on the optimization of Example 1-2, refer to Figure 1-4 The number of the card slots 11 and the number of the reinforcement rods 12 are both two, and the two card slots 11 and the two reinforcement rods 12 are symmetrically arranged around the motor 7 , and the depth of the card slots 11 is consistent with the depth of the groove 9 .
[0028] By arranging the card slot 11 and the reinforcement rod 12 symmetrically around the motor 7, the gravity generated by the fixed frame 6, the weight block 4, the motor 7, and the first threaded rod 8 on the moving block 5 in Example 1 can be shared by the two reinforcement rods 12, thereby reducing the probability of the moving block 5 causing the groove 9 to deform, thereby increasing the service life of the device; by setting the depth of the card slot 11 to be consistent with the depth of the groove 9, the position of the moving block 5 in the groove 9 can be determined by observing the position of the reinforcement rod 12 in the card slot 11, thereby facilitating the probability of the position of the weight block 4. When encountering similar terrain in the later stage, it is convenient to adjust the position of the weight block 4, thereby reducing the calibration time of the device.
[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
