Description

Technical Field

[0001] The utility model relates to the technical field of agricultural implements, in particular to an automatic deep loosening machine which is convenient for adjusting the loosening depth. Background Art

[0002] A subsoiler is a farming machine used in conjunction with a high-horsepower tractor. It is mainly used for mechanized tillage of deep soil between rows or in all directions. It has the functions of breaking the bottom layer of the plow, restoring the structure of the soil plow layer, improving the soil's ability to store water and retain moisture, eliminating some weeds, reducing pests and diseases, leveling the surface, and improving the standard of agricultural mechanization operations. Subsoilers are widely used in agriculture.

[0003] However, the existing deep tillage machine needs to remove the bolts fixing the tillage blade and re-fix the tillage blade in order to adjust the loosening depth. Therefore, the equipment cannot quickly till the soil at different depths. Therefore, an automatic deep tillage machine that is easy to adjust the loosening depth is proposed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figures 1 to 4 The utility model provides an automatic deep loosening machine which is convenient for adjusting the loosening depth: it comprises a frame 1, a connecting plate 2 is fixedly arranged in the frame 1, a connecting frame 3 is fixedly arranged on the top of the connecting plate 2, mounting frames 4 are fixedly arranged on both sides of the frame 1, supporting wheels 5 are arranged in the mounting frames 4, a plurality of mounting cylinders 6 are fixedly arranged at the bottom of the frame 1, a connecting rod 7 is movably arranged in the mounting cylinder 6, limiting grooves 11 are arranged on the front inner wall and the back inner wall of the mounting cylinder 6, limiting blocks 9 are fixedly arranged on the front and back sides of the connecting rod 7, the limiting blocks 9 and the limiting grooves 11 are movably connected, a tilling blade 8 is fixedly arranged at the bottom of the connecting rod 7, and a plurality of positioning holes 10 are arranged on one side of the connecting rod 7;

[0027] Reference Figure 4In order to achieve the purpose of rapid adjustment, a positioning structure 12 is provided on one side of the mounting tube 6. The positioning structure 12 includes a fixing frame 121 fixedly connected to the mounting tube 6. A positioning rod 122 is movably provided on the fixing frame 121. One end of the positioning rod 122 passes through the mounting tube 6 and extends into the positioning hole 10. A first spring 123 is sleeved on the positioning rod 122. Two baffles are fixedly provided on the outside of the positioning rod 122. One end of the first spring 123 is in contact with the mounting tube 6, and the other end of the first spring 123 is in contact with the two baffles. Two slide grooves 124 are provided on the front of the fixing frame 121. A slider 122 is movably provided in the slide groove 124. 6. A slide bar 125 is fixedly provided in the slide groove 124, and a second spring is sleeved on the slide bar 125. The slider 126 is movably connected to the slide bar 125, and a limit plate 127 is fixedly provided on the slider 126. When the opening depth needs to be adjusted, the two limit plates 127 are pulled away from each other to make them break away from the contact with the positioning rod 122. The positioning rod 122 is pushed outward by the first spring 123 and breaks away from the contact with the positioning hole 10. At this time, the connecting rod 7 can be held to adjust the extension length of the tilling blade 8 to adjust the opening depth. There is no need to remove the tilling blade 8 and readjust the height, which can speed up the rapid adjustment of the length of the tilling blade 8.

[0028] Reference Figure 3 In order to achieve the purpose of protection, a protective structure 13 is provided on one side of the mounting tube 6. The protective structure 13 includes an external threaded tube 131 fixedly connected to the mounting tube 6, and an outer sleeve 132 is movably provided on the external threaded tube 131. After adjustment, the outer sleeve 132 is installed on the external threaded tube 131, which can effectively prevent soil from entering the gap between the movable connection between the positioning rod 122 and the fixing frame 121, thereby ensuring the normal extension and retraction of the positioning rod 122.

[0029] Working principle: When the opening depth needs to be adjusted, first rotate the outer sleeve 132 counterclockwise to remove it from the external threaded tube 131, and then pull the two limit plates 127 away from each other. The limit plate 127 drives the slider 126 to squeeze the second spring on one side. When the limit plate 127 is out of contact with the positioning rod 122, the first spring 123 pushes the baffle, and the baffle drives the positioning rod 122 to move to one side, so that one end of it is out of contact with the positioning hole 10. At this time, the connecting rod 7 can be held to adjust the extension length of the tiller 8 to achieve the opening depth. After the adjustment is completed, the positioning rod 122 is squeezed inwardly so that one end of the positioning rod 122 is inserted into the positioning hole 10, and then the limit plate 127 is loosened. The second spring restores the position of the slider 126, so that the two limit plates 127 fit the positioning rod 122 to limit the positioning rod 122, thereby realizing rapid adjustment of the opening depth. Finally, the outer sleeve 132 is installed on the external threaded tube 131 to protect the positioning structure 12, which can effectively prevent soil from entering the gap between the positioning rod 122 and the fixing frame 121.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
