For the mulch film precision sealing machine, in the transmission system, the shaft 14 is the output shaft of the gearbox 15 . Axle 14 left side is positioned with driving sprocket 4, forms chain drive by transmission chain 16 and crushed soil sprocket 5, sends soil sprocket 6, and right side is positioned with driving sprocket 4, by transmission chain 16 and crushed soil sprocket 5 , Covering soil sprocket wheel 17 constitutes chain drive.

For the mulch film precision sealing machine, in the soil fetching and screening system, the two soil fetching wheel assemblies 3 on the left and right are connected to the shaft (14), and the soil fetching wheel guards 13 on the left and right sides are covered by the soil fetching wheel assembly. 3, two broken soil nail teeth 2 are connected with two broken soil sprockets 5 of effect respectively, and its bottom is broken soil grid bar 7.

For the mulch film precision sealing machine, in the soil sending and sealing system, the soil sending drum 12 is connected with the soil sending sprocket 6, and the left side spiral drum 8 and the right side spiral drum 10 are evenly distributed with three soil retaining barrels 11, and are connected with Covering soil sprocket 17 is connected.

For the mulch precision soil sealing machine, in the ground soil profiling mechanism, the soil guide groove support 19 is positioned at the excavation opening of the rear lower part of the frame, and is hinged with the soil guide groove 9 by the rotating pin 20, and the soil guide groove 9 bottom is Roller 18.

Detailed ways

The invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the pole is hooked to the rear of the tractor through the three-point suspension on the frame 1, and the power is transmitted to the gearbox through the rear power output shaft, and the gearbox 15 then transmits the power to the shaft 14. The earth taking and crushing parts are symmetrically arranged. After cutting the earth taking wheel guard 13, it can be seen that the left earth taking wheel assembly 3 has a certain machete, and the shaft 14 distributes the power to the driving sprockets at both ends. 4. The left and right earth-taking wheel assemblies 3 connected to the shaft 14 rotate, chop the soil on the ground surface and throw it to the left and right soil-crushing nail teeth 2 at the upper rear, and send it to the top of the soil-crushing nail teeth 2. The nail teeth 2 rotate to further break up the soil on the ground surface.

As previously mentioned, the left driving sprocket 4 distributes the power to the left side broken soil sprocket 5 and the soil sending sprocket 5 respectively through the chain drive and drives them to rotate together, respectively distributing the power to the left side broken soil nail teeth 2 and The soil sending sprocket 6 and the right driving sprocket 4 respectively distribute power to the right crushing sprocket 5 and the covering sprocket 17 through chain transmission, and drive them to rotate together, respectively distributing the power to the right crushing nail teeth 2 And cover sprocket wheel 17.

As previously mentioned, the left and right crushing soil sprockets 5 drive the left and right crushing nail teeth 2 to rotate, and the crushed soil sprinkled by the left and right soil taking wheel assemblies 2 is further crushed, and the crushed soil passes through the left and right crushing soil bars 7 The sieved soil falls into the soil sending drum 12 below. At this time, the soil sending drum 12 is rotated by the power transmitted by the soil sending sprocket 6, and the finely crushed soil is transported to the middle of the drum. At this time, the pushing of the soil sending drum 12 is still It has the function of further crushing the clods.

As mentioned above, after the soil sending roller 12 sends the crushed soil to the middle, it is pushed to both sides by the left screw drum 8 and the right screw drum 10 respectively. Due to the soil retaining effect of the soil retaining bucket 11, quantitative The crushed soil falls into the excavation opening below the soil retaining bucket, which ensures the uniformity of excavation.

As previously mentioned, the soil guide tank support 19 below the outlet port sends broken soil into the soil guide tank 9, because the roller 18 installed on the soil guide tank 9 is in contact with the ground, and is hinged with the soil guide tank support 19 by the rotating pin 20 Therefore, the ground profiling of the soil guide groove 9 has been realized, thereby ensuring that the unearthed height of the soil guide groove 9 is always a certain height with the ground, ensuring that the crushed soil is evenly sprinkled on the hole sowing opening of the plastic film of the plant seedling, and the hole sowing hole To seal, to serve the purpose of sealing the soil. After the soil sending roller 12 sends the crushed soil to the middle, the wind is pushed to both sides by the left spiral drum 8 and the right spiral drum 10. Due to the soil retaining effect of the soil retaining bucket 11, a quantitative amount of crushed soil can be guaranteed at this time. Falling into the bottom of the soil retaining bucket ensures the uniformity of excavation.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not limit them. Although the innovation of the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be Modifications or equivalent replacements of the technical solutions without departing from the spirit and scope of the solutions of the present invention are all included in the scope of the claims of the present invention.
