A soil loosening device for vegetable growing

Abstract

This invention belongs to the technical field of vegetable soil loosening equipment, and provides a soil loosening device for vegetable planting, including a bearing unit and an adjustment unit. The bearing unit includes a protective frame, which is hollow. The inner wall of the protective frame has vertically formed first receiving grooves and first sliding grooves on both sides, with the first receiving grooves located at the top of the first sliding grooves. The invention uses a first telescopic rod to drive a limiting plate down along the first sliding groove, causing the limiting plate to gradually insert the bottom of the shovel plate vertically into the soil. Then, by activating a second telescopic rod, the second telescopic rod drives a connecting block down along a fourth sliding groove via an adjustment block. When the limiting block moves to the corner of the fourth sliding groove, under the downward pressure of the second telescopic rod, the limiting block drives the connecting block to rotate 90° clockwise, thereby causing the shovel plate to rotate 90° clockwise. This allows the device to be adjusted according to the required soil loosening depth for different vegetables, expanding the device's applicability.

[0050] Annular mounting blocks 1810 for supporting the crushing blades 1811 are fixedly connected to both the first driven shaft 181 and the second driven shaft 182. The annular mounting blocks 1810 are located inside the receiving frame 183. Multiple sets of crushing blades 1811 for crushing soil are fixedly connected to the annular mounting blocks 1810.

[0051] It should be noted that an electromagnet is embedded in the slope 1812. By energizing the electromagnet, the magnet removes any magnetic materials that may be mixed in with the soil, thus protecting the crushing blade 1811 while improving the purity of the soil.

[0052] It should be noted that the sieve 1813 and the receiving frame 183 are detachably connected, and the operator can change the sieve 1813 with different mesh sizes according to the looseness of the soil for different kinds of vegetables.

[0053] The movable component 19 includes a rotating shaft 192 that rotates horizontally through the protective frame 11 and follows the driven roller 191, and a connecting shaft 193 that is fixed on both sides of the protective frame 11 to limit the second rotating wheel 195. The rotating shaft 192 is connected to the protective frame 11 by bearings. Both ends of the rotating shaft 192 are provided with a first rotating wheel 194 that rotates with the rotating shaft 192. The first rotating wheel 194 is connected to the rotating shaft 192 by a universal joint. The driven roller 191 is fixedly sleeved on the rotating shaft 192. One end of the connecting shaft 193 is connected to the second rotating wheel 195 that drives the equipment to move by a universal joint.

[0054] Example 1: As Figures 1-12 As shown, in this embodiment, when it is necessary to loosen the soil, the screen 1813 with the required soil looseness for vegetables is replaced first, and the first telescopic rod 26 is activated, so that the first telescopic rod 26 drives the limiting plate 23 to descend along the first sliding groove 13. During the process of the limiting plate 23 descending, the bottom end of the soil shovel 27 is gradually inserted vertically into the soil.

[0055] When the limiting plate 23 descends to the required soil loosening depth, the second telescopic rod 29 is activated. The second telescopic rod 29 drives the connecting block 21 to descend along the fourth slide 24 via the adjusting block 28. When the limiting block 25 moves to the corner of the fourth slide 24, under the downward pressure of the second telescopic rod 29, the limiting block 25 drives the connecting block 21 to rotate 90° clockwise, which in turn drives the shovel plate 27 to rotate 90° clockwise. This allows the equipment to be adjusted according to the required soil loosening depth for different vegetables, expanding the applicability of the equipment.

[0056] During the process of adjusting the soil loosening depth according to different vegetables, the second connecting rod 173 in the conveyor 17 moves with the connecting block 21. The second connecting rod 173 drives the first connecting rod 171 to move along the limiting groove 14 through the toothed belt 175. During the movement of the first connecting rod 171, the elastic element 1710 on one side of the first connecting rod 171 is subjected to pressure, and the pressure on the elastic element 1710 on the other side of the first connecting rod 171 is reduced, thereby causing the elastic element 1710 to undergo elastic deformation, which in turn drives the fixing block 179 and the soil retaining plate 1711 to move, thereby causing the soil retaining plate 1711 to block the limiting groove 14 and prevent soil from leaking out of the protective frame 11 from the limiting groove 14 when the toothed belt 175 is conveying soil.

[0057] When the first connecting rod 171 moves along the limiting groove 14, the first connecting rod 171 drives the stepper motor 176 to move along the limiting groove 14, so that the stepper motor 176 drives the slider 178 to move along the second slide groove 15 through the limiting frame 177; the length of the first belt 188 is adjusted according to the distance between the first connecting roller 186 and the transmission roller 172, thereby ensuring the normal operation of the device.

[0058] After adjusting the soil loosening depth according to the different vegetables, the stepper motor 176 is started, causing the stepper motor 176 to drive the first connecting rod 171 to rotate. The first connecting rod 171 drives the rotating shaft 192 to rotate through the transmission roller 172, the first belt 188, the first connecting roller 186, the first driven shaft 181, the first driven gear 184, the second driven gear 185, the second driven shaft 182, the second connecting roller 187, the second belt 189, and the driven roller 191, thereby driving the first rotating wheel 194 to rotate and driving the equipment to perform soil shoveling operations.

[0059] When the equipment moves, the first connecting rod 171 drives the toothed belt 175 through the transmission gear 174 to transport the soil shoveled on the shovel plate 27. The soil shoveled on the shovel plate 27 is transported to the receiving frame 183 by the toothed belt 175. Under the action of the transmission roller 172, the first belt 188 and the first connecting roller 186, the first driven shaft 181 starts to rotate. The first driven shaft 181 drives the second driven shaft 182 to rotate under the action of the first driven gear 184 and the second driven gear 185, which in turn drives the annular mounting block 1810 and the crushing blade 1811 to rotate, thereby crushing the soil transported by the toothed belt 175.

[0060] During the soil crushing process, the slope 1812 guides the soil onto the screen 1813, which screens the crushed soil. Soil particles of suitable size fall to the ground through the screen 1813, while larger soil particles remain in the receiving frame 183 for further crushing, thereby making the crushed soil loose enough to meet the requirements for planting vegetables.

[0061] It should be noted that: the top of the protective frame 11 has a vertical through hole, which is connected to the internal space of the receiving frame 183. A plug is installed in the through hole. During the operation of the crusher 18, the operator can remove the plug in the through hole and pour the fertilizer into the receiving frame 183 along the through hole. The crusher 18 will then mix the fertilizer with the soil, thereby achieving simultaneous loosening of the soil and fertilization.

[0062] It should be noted that the above method can also be used when operators need to adjust the soil pH, so as to achieve simultaneous soil loosening and pH adjustment.

[0063] After the soil is loosened, the screen 1813 is removed, and the electromagnet on the slope 1812 is de-energized, so that the magnetic material collected by the electromagnet slides down the slope 1812 to the ground.

[0064] The embodiments of the present invention are given for the purposes of illustration and description. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
