Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a ground film covering device. Background Art

[0002] The existing colored peppers are a special series of sweet peppers, which are available in yellow, red, white, green, purple, orange and other colors. A mulch covering device is required during the planting process of colored peppers.

[0003] At present, there is an existing high-efficiency film covering device for pepper planting (such as patent number: CN217958052U), which discloses a ground film covering device, including a movable body, a support plate is provided under the movable body, two mounting plates are fixed on the surface of the support plate, and the mounting plate is fixedly connected to the bottom surface of the movable body by a plurality of screws, a controller is provided on the surface of the support plate, and two rectangular grooves are provided on the surface of the support plate; thereby, an efficient film covering effect can be achieved through the movable body and the film covering mechanism, and the fixed shaft is fixedly connected to the two fixed plates by screws, so that the film covering roller can be replaced for the next film covering work, and by setting a film pressing mechanism, the soil can be covered on both sides of the ground film during the film covering process to prevent the ground film from being deformed or deviating from the area to be covered due to the influence of wind after covering, so that the ground film can be sprayed with water during the film covering process to increase the fit between the ground film and the ground and increase the moisture in the soil.

[0004] However, during the implementation of the above technical solution, it was found that there are at least the following problems: the soil needs to be put into the film pressing mechanism for covering the device. This process requires the staff to prepare the soil in advance, which increases the workload of the staff. In order to reduce the workload of the staff, the existing ground film covering device changes the film pressing mechanism, and the film pressing disk is rotatably connected to the two ends of the device. The film pressing disk rotates with the movement of the device to move the soil to the top of the ground film. However, when installing the film roller in this ground film covering device, the two ends of the film roller are only placed on the inner side of the mounting frame at both ends of the bracket. As the ground film on the film roller decreases, the weight of the film roller decreases, and the vibration generated by the operation of the device can easily cause the connection between the film roller and the mounting frame to be released, thereby affecting the normal operation of the device.

As the film on the film covering roller decreases, the weight of the film covering roller decreases, and the vibration generated by the operation of the device easily causes the connection between the film covering roller and the mounting frame 2 to be released, thereby affecting the normal operation of the device. The overall idea is as follows:

[0028] Each fixing mechanism includes a slide groove 4, a pressure plate 5, a groove 6, a threaded hole 7, a fixing screw 8 and a mounting plate 9;

[0029] The slide groove 4 is provided on the outside of the mounting frame 2, the pressing plate 5 is slidably connected to the inside of the slide groove 4, the groove 6 is provided at one end of the pressing plate 5 away from the slide groove 4, the threaded hole 7 is provided on the outside of the pressing plate 5, the threaded hole 7 is communicated with the groove 6, the fixing screw 8 is threadedly connected to the inside of the threaded hole 7, and the mounting plate 9 is fixedly connected to the outside of the mounting frame 2;

[0031] By setting the fixing screws 8 and cooperating with the pressure plate 5, when the two ends of the coating roller are respectively placed on the inner sides of the mounting frame 2, the pressure plate 5 is pressed downward and slid so that the pressure plate 5 fits with the end of the coating roller located on the inner side of the mounting frame 2. At this time, the other end of the pressure plate 5 is slidably connected to the outside of the mounting plate 9 through the groove 6. At this time, the fixing screws 8 can be rotated to fit the fixing screws 8 and the pressure plate 5 to fix the pressure plate 5. At this time, the two ends of the coating roller are fixed. When the weight of the coating roller decreases, the vibration generated by the operation of the device will not cause the connection between the coating roller and the mounting frame 2 to be released, thereby preventing the normal operation of the device from being affected.

[0032] A protective plate 10 is provided on the outside of each mounting frame 2;

[0033] The protection plate 10 is in contact with a side of the fixing screw 8 away from the mounting plate 9 , thereby limiting the movement of the fixing screw 8 .

[0034] Each mounting frame 2 is provided with a mounting groove 11 on its exterior;

[0035] The protection plate 10 is snap-fitted into the installation slot 11 , which facilitates the disassembly and assembly of the protection plate 10 .

[0036] Each protective plate 10 is slidably connected to a limiting plate 13 inside, and the limiting plate 13 is a concave body;

[0037] A limiting groove 15 is formed inside each installation groove 11 , and the limiting plate 13 is slidably connected inside the limiting groove 15 , so as to strengthen the connection between the protective plate 10 and the installation groove 11 .

[0038] Each protective plate 10 has a built-in groove 12 formed inside, and each protective plate 10 has two openings 14 formed outside, and the two openings 14 are communicated with the built-in groove 12;

[0039] The limiting plate 13 is slidably connected to the inside of the protective plate 10 through the built-in groove 12 , and the two ends of the limiting plate 13 are slidably connected to the inside of the two openings 14 , so as to facilitate the operation of the limiting plate 13 .

[0040] Two springs 16 are fixedly connected inside each built-in groove 12;

[0041] One end of the limiting plate 13 away from the hole 14 is fixedly connected to the outside of the two springs 16 , so as to provide support for the limiting plate 13 .

[0042] By setting the protective plate 10 and cooperating with the limiting plate 13, after the fixing screw 8 is fitted with the pressure plate 5, the upper end part of the limiting plate 13 is pressed so that the two ends of the limiting plate 13 enter the inside of the opening 14. At this time, the spring 16 is compressed. At this time, the protective plate 10 is inserted into the inside of the installation groove 11. At this time, the upper end part of the limiting plate 13 is loosened. At this time, the lower end of the limiting plate 13 enters the inside of the limiting groove 15 under the action of the spring 16. At this time, the protective plate 10 is installed in the inside of the installation groove 11. At this time, the protective plate 10 is fitted with the outside of the fixing screw 8, thereby limiting the rotation of the fixing screw 8, reducing the probability of the fixing screw 8 loosening due to the vibration generated by the operation of the device, thereby improving the stability of the installation of the pressure plate 5.

[0043] Working principle:

[0044] In the first step, when the two ends of the coating roller are placed on the inner side of the mounting frame 2 respectively, the pressing plate 5 is pressed downward and slid to make the pressing plate 5 fit with the end of the coating roller located on the inner side of the mounting frame 2. At this time, the other end of the pressing plate 5 is slidably connected to the outside of the mounting plate 9 through the groove 6. At this time, the fixing screw 8 can be rotated to make the fixing screw 8 fit with the pressing plate 5 to fix the pressing plate 5. At this time, the two ends of the coating roller are fixed. When the weight of the coating roller decreases, the vibration generated by the operation of the device will not cause the connection between the coating roller and the mounting frame 2 to be released, so as to prevent affecting the normal operation of the device;

[0045] The second step is to press the upper end of the limiting plate 13 so that both ends of the limiting plate 13 enter the interior of the opening 14. At this time, the spring 16 is compressed. At this time, the protective plate 10 is inserted into the interior of the mounting groove 11. At this time, the upper end of the limiting plate 13 is loosened. At this time, the lower end of the limiting plate 13 enters the interior of the limiting groove 15 under the action of the spring 16. At this time, the protective plate 10 is installed in the interior of the mounting groove 11. At this time, the protective plate 10 is in contact with the outside of the fixing screw 8, thereby limiting the rotation of the fixing screw 8.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
