Description

Technical Field

[0001] The present invention relates to the field of agricultural planting equipment, and more specifically, to a film covering equipment used for agricultural planting. Background Art

[0002] Film covering equipment in agricultural planting is an important part of modern agricultural technology. They play an important role in improving agricultural production efficiency and protecting the crop growth environment. Plastic film is covered on the surface to maintain soil moisture, increase ground temperature and promote crop growth. Fertilizers applied to the soil under the protection of the film will not be lost due to wind, sun and rain, and the growth of weeds can be effectively controlled. The colorless film has a strong ability to reflect light and improve the light and heat conditions of the near-ground atmosphere. Film covering cultivation also promotes soil microbial activity, accelerates the decomposition of organic matter, improves the physical and chemical structure of the soil, and creates a suitable ecological environment for the growth of crops.

[0003] Referring to the Chinese patent application with publication number CN113711827B, a film covering device for agricultural planting is disclosed, which can automatically complete the film covering work by automatically driving the main box to move forward step by step, and in the process of moving forward, the film can be pressed into the soil by a tamping rod to enhance the fixing effect of the film covering;

[0004] However, in the prior art, land ridge making, film covering and seeding are performed separately, and the efficiency of agricultural planting has a large room for development.

The fourth motor 25 is fixedly mounted on the moving block, and the output end of the fourth motor 25 is coaxially fixedly connected with one of the bevel gears 26, and the end of the transmission plate 27 close to the bevel gear 26 is provided with end face teeth meshing with the bevel gear 26, and a plurality of moving guide grooves are provided on the side wall of the second mounting plate 23, and a plurality of moving connecting blocks 28 are respectively arranged in the plurality of moving guide grooves, and the end of the moving connecting block 28 close to the transmission plate 27 is provided with meshing teeth 281, and the end of the transmission plate 27 close to the second mounting plate 23 is provided with vortex teeth adapted to the meshing teeth 281, and the ends of the plurality of moving connecting blocks 28 away from the meshing teeth 281 are respectively fixedly connected with the plurality of cavitation devices 24;

[0049] The effect of such arrangement is that after the ridging device 36 has ridged the ground, the film coating roller 171 on the machine body 1 attaches the ground film to the ground after the ridging, and the ground film is pierced by controlling the ground spikes on the machine body 1. At the same time, the first movable platform 111 is driven to move on the mounting frame 11 by the output end of the first motor 12, and the clamping part 13 is controlled to move on the first movable platform 111, so as to facilitate the removal of the seedlings to be planted in the placement groove 141.

[0051] like Figure 1 and Figure 2As shown, a first slide groove is provided on the mounting frame 11, a first screw is provided in the first slide groove, a first slider is provided on the first movable platform 111, the first slider is arranged in the first slide groove, and a threaded hole matching the thread of the first screw is provided on the first slider, a first motor 12 is fixedly installed on the machine body 1, an output end of the first motor 12 is coaxially fixedly connected with one of the first screws, and a same connecting belt is wound between a group of first screws;

[0052] A group of mounting grooves 15 are provided on the machine body 1, and a second screw is provided in the mounting grooves 15. A group of second sliders are provided on the second moving platform 16, and a group of second sliders are respectively provided in a group of mounting grooves 15, and a threaded hole matching the thread of the second screw is provided on the second slider. A second motor 151 is fixedly installed on the machine body 1, and an output end of the second motor 151 is coaxially fixedly connected with one of the second screws, and a common transmission belt 152 is wound between the group of second screws.

[0054] The effect of such arrangement is that the output end of the first motor 12 drives the first movable platform 111 to move on the mounting frame 11, and controls the clamping part 13 to move on the first movable platform 111, so as to facilitate taking out the seedlings to be planted in the placement groove 141, and at the same time, the output end of the second motor 151 is controlled by the control panel to drive the second movable platform 16 to move on the machine body 1, and controls the movable plate 2 to move on the second movable platform 16, and the movement of the movable plate 2 corresponds to the movement of the clamping part 13, so as to facilitate the automatic sowing of the seedlings to be planted, and realize the integrated operation of ridging, film covering and sowing of the land, and at the same time, fertilization and irrigation mechanisms can be added to the machine body 1 to realize automatic integrated planting operations, and the planting efficiency is greatly improved.

[0055] From the above, we can see that the working principle of this application is as follows:

[0056] The output end of the fifth motor 33 is controlled by the control panel to work, so that the second threaded rod 331 rotates, and the nut connecting block 321 drives the lifting platform 32 to move in the installation frame 3 under the restriction of the guide groove 31 and the thread cooperation with the second threaded rod 331. Since a plurality of guide limit grooves 322 are evenly provided on the surface of the installation frame 3 that contacts the lifting platform 32, the limit block 351 on the sliding block 35 is arranged in the guide limit groove 322, and the plurality of sliding blocks 35 are evenly arranged on a group of optical axes 34. Since the guide limit grooves 322 are inclined, when the fifth motor 33 drives the lifting platform 32 to move up and down in the installation frame 3, the plurality of sliding blocks 35 are close to or away from each other, so that the equal spacing between the plurality of sliding blocks 35 is achieved. At the same time, a plugging is provided on the sliding block 35, and the plugging is fixed to the sliding block 35 by bolts.

[0058] The clamping part 13 puts the clamped seedlings to be planted into the discharge port 211 of the guide discharge cylinder 21, and the seedlings to be planted move along the guide discharge cylinder 21 to the hole former 24. At the same time, by moving the guide discharge cylinder 21 downward, the hole former 24 is inserted into the ground, and then the fourth motor 25 is controlled by the control panel to drive one of the bevel gears 26 to rotate. The bevel gear 26 is meshed with the end face teeth on the transmission disk 27 for transmission. At the same time, under the rotation of the transmission disk 27, the spiral teeth cooperate with the meshing teeth 281 on the mobile connecting block 28, so that multiple mobile connecting blocks 28 move outward synchronously, and the hole former 24 inserted into the ground is opened, and the seedlings to be planted originally located in the closed hole former 24 fall into the opened hole.
