DETAILED DESCRIPTION

[0021] In order to make the above purpose, features and advantages of the utility model more obvious and easy to understand, the following will make detailed description to the specific implementation of the utility model by combining with the drawings in the specification.

[0022] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can be practiced in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore, the present application is not limited to the specific embodiments disclosed below.

"In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent of or mutually exclusive with other embodiments.

[0024] As shown in the accompanying drawings Figure 1 , 2 and the accompanying drawings Figure 3 :

[0025] Embodiment one: the embodiment provides a double-row perforated film under drip irrigation seeding machine with adjustable row spacing, which comprises two seeding mechanisms 1 and a row spacing adjusting mechanism 2; the seeding mechanism 1 comprises a seeding wheel 101, the side of the seeding wheel 101 is provided with a seed bin 102, and the seed bin 102 is fixedly installed with a fixed frame 103; the row spacing adjusting mechanism 2 comprises a gear reversing device 201, the input end of the gear reversing device 201 is provided with a driving piece 203, and the two output ends of the gear reversing device 201 are both installed with a threaded rod 204; the fixed frame 103 of the two seeding mechanisms 1 is both installed with a threaded cylinder 205, and the threaded cylinder 205 is threadedly connected with the threaded rod 204.

[0026] The seeding mechanism 1 is an existing drip irrigation seeder, and the working principle is that the seed bin 102 stores seeds, when the personnel push the device to make the seeding wheel 101 roll, the duckbill on the outer surface of the seeding wheel 101 will be inserted into the soil in turn to complete the punching, and the duckbill will be automatically opened in the process, so as to place the seeds in the hole to complete the seeding, which is the prior art, and therefore, excessive description will not be made, and the hole spacing of the duckbill is between 3-10 cm;

[0027] Two seeding mechanisms 1 are adopted, which can simultaneously perform two-row seeding operation under the condition that a single person pushes the device, greatly improving the work efficiency;

[0028] The driving piece 203 can be started in the process, which includes but is not limited to a motor, the motor transmits the driving force to the threaded rod 204 through the gear reversing device 201, the threaded directions of the two threaded rods 204 are opposite, and then the threaded cylinder 205 is driven to move synchronously together or separately when rotating, the threaded cylinder 205 will drive the seeding mechanism 1 to move through the fixed frame 103, so as to adjust the distance between the two seeding mechanisms 1, thereby adjusting the row spacing of the double-row seeding, and improving the flexibility and application range of the device;

[0029] The gear reverser 201 is a worm gear reverser, the electric motor drives the worm to rotate, the power is transmitted to the worm wheel through the meshing of the worm and the worm wheel, and the two threaded rods 204 are connected with the two ends of the worm wheel respectively to complete the transmission, the speed reduction transmission of the worm gear can improve the adjustment accuracy, and the self-locking effect is obtained, and the stability after adjustment is improved.

[0030] Specifically, the gear reverser 201 on the periphery of the threaded cylinder 205 is fixedly installed with a protective shell 206, and the threaded cylinder 205 and the protective shell 206 are both square, the protective shell 206 not only limits and guides the moving direction of the threaded cylinder 205, but also shields the threaded cylinder 205, and can shield the threaded rod 204 at all times in cooperation with the threaded cylinder 205, so that the device service life is not affected by the soil entering the device during sowing.

[0031] Specifically, the gear reverser 201 is fixedly installed with a holding rod 202, and the holding rod 202 is telescopically connected with the fixed frame 103, the two fixed frames 103 can be connected together through the holding rod 202, the connection stability between the two seeding mechanisms 1 is greatly improved, when adjusting the row spacing, the fixed frame 103 will telescopically move in the holding rod 202, and the holding range of the holding rod 202 is always kept connected, and the personnel holding is facilitated.

[0032] As shown in the accompanying drawings: Figure 1 , 3 and the accompanying drawings: Figure 4

[0033] Embodiment two: the embodiment is basically the same as the above embodiment, the difference lies in that the double-row perforated film under-drip irrigation seeder further comprises a supporting mechanism 3, the supporting mechanism 3 comprises connecting frames 301 arranged at the bottom of both sides of the gear reverser 201, and the connecting frames 301 are movably installed with a soil covering wheel 303 through a support 302.

[0034] Specifically, the support 302 and the soil covering wheel 303 are provided with two groups, and the two groups of supports 302 and soil covering wheels 303 are located at the bottom of both ends of the connecting frame 301.

[0035] Specifically, springs 304 are installed between the supports 302 of the two soil covering wheels 303.

[0036] The driving member 203 can adopt a rotating wheel, and a rotating driving force can be manually applied to change the device into a non-electric structure, reduce the gravity of the device, and further increase the application range;

[0037] ​The gear commutator 201 is a worm gear commutator. The motor drives the worm to rotate, and the power is transmitted to the worm wheel through the meshing of the worm and the worm wheel. The two threaded rods 204 are connected to the two ends of the worm wheel respectively to complete the transmission. The speed reduction transmission of the worm gear can improve the adjustment accuracy, and at the same time, it has a self-locking effect, improves the stability after adjustment, reduces the resistance of the operator to rotate the wheel, and eliminates the need for manual locking after adjustment.

[0038] As can be seen from the above, during the process of moving the device for sowing, the soil-covering wheel 303 will roll on the ground, thereby covering and pressing the sown holes with soil. The two soil-covering wheels 303 can be set up so that the device can be stably stopped on the ground when it is not working, without the need for personnel to hold it, thus improving stability. When personnel need to adjust the row and plant spacing, they only need to hold the handle 202 and press down, which will lift the sowing wheel 101 with the soil-covering wheel 303 as the midpoint, making it convenient for personnel to make adjustments. The two soil-covering wheels 303 can improve stability when the sowing wheel 101 is lifted. At the same time, due to the increased downward pressure, they will rotate and open on the connecting frame 301 to be buffered by the spring 304. The two soil-covering wheels 303 will open synchronously to both ends of the device to avoid instability caused by synchronous forward or backward movement, and will increase the ground contact area, further improving stability.
