When fertilizer needs to be added, the cover bolt 104 is rotated to disconnect the cover bolt 104 from the storage tank 102, and then the cover 103 can be manually rotated to open the storage tank 102, and then the fertilizer can be put into the storage tank 102. After being filled, the storage tank 102 can store 1.4 kilograms of fertilizer.
[0020] like Figures 1 to 4As shown, a dosage barrel 201 is fixedly installed at one end of the storage tank 102 away from the handle 101, and the diameter of the dosage barrel 201 is half of the storage tank 102. An inclined surface is provided at the connection between the storage tank 102 and the dosage barrel 201, and its purpose is to allow the fertilizer in the storage tank 102 to completely fall into the dosage barrel 201. The end of the dosage barrel 201 away from the storage tank 102 is provided with a protruding flat shovel 208 for penetrating into the soil. The end of the dosage barrel 201 provided with the protruding flat shovel 208 is the outlet end, and the protruding flat shovel 208 is connected to the outlet end on the dosage barrel 201 through threads. The shape of the outlet end on the dosage barrel 201 is conical, which is conducive to completely spreading the fertilizer into the pits for planting. When there are no pits in the soil, simple digging is required through the protruding flat shovel 208, and when there are pits, the protruding flat shovel 208 can also be removed from the thread of the outlet end.
[0021] like Figures 2 to 5As shown, a pressing ring 218 for being pressed is slidably installed on the outer wall of the dose barrel 201, and a plurality of pressure plate springs 206 for restoring the position of the pressing ring 218 are fixedly installed on one end of the pressing ring 218 close to the storage tank 102, and the other end of the pressure plate spring 206 is fixedly connected to the outer wall of the dose barrel 201. A block barrel 202 is also fixedly installed on the pressing ring 218, and the block barrel 202 is arranged on the inner wall of the dose barrel 201, and the block barrel 202 is slidably connected to the inner wall of the dose barrel 201, and the block The function of the cylinder 202 is to block the slide groove on the dosage cylinder 201 to prevent the fertilizer from falling out of the dosage cylinder 201. A leakage block 205 is fixedly installed in the block cylinder 202. The leakage block 205 is slidably connected to the outlet end of the dosage cylinder 201. In the initial state, the leakage block 205 closes the outlet end of the dosage cylinder 201. An adjusting screw 204 is rotatably installed in the leakage block 205. The end of the adjusting screw 204 away from the storage tank 102 is fixedly installed with an inner hand The inner handle 207 is rotatably connected to the leakage stopper 205. The end of the adjusting screw rod 204 away from the inner handle 207 is provided with an inner hollow cylinder 203, and the inner hollow cylinder 203 is connected to the adjusting screw rod 204 by threads. The inner hollow cylinder 203 is a cylindrical setting to provide a movable space for the adjusting screw rod 204. A driving column 215 is fixedly installed on the inner hollow cylinder 203, and a rotating slide groove is provided on the outer wall of the driving column 215. When the pressing ring 218 is pressed and squeezed, the pressing ring 218 moves to When moving toward the storage tank 102, the pressing ring 218 will also drive the block cylinder 202 and the leakage block 205 to slide on the inner wall of the dosage cylinder 201, so that the leakage block 205 can be separated from the contact with the inner wall of the dosage cylinder 201 after sliding, thereby opening the outlet end of the dosage cylinder 201 and allowing the fertilizer to fall out of the dosage cylinder 201 into the soil pit. When the pressure on the pressing ring 218 disappears, the leakage block 205 will return to the initial position to close the outlet end of the dosage cylinder 201.
[0022] like Figures 3 to 6As shown, a sliding block 213 is slidably installed on the inner wall of the dosage barrel 201. The sliding block 213 is semicircular and has the same diameter as the inner wall of the dosage barrel 201. An intermediate column 214 is rotatably installed on the sliding block 213. The intermediate column 214 is arranged on a rotating slide groove. The connection between the intermediate column 214 and the rotating slide groove is to convert the linear movement of the driving column 215 into the rotational movement of the intermediate column 214. A closed block 216 serving as a fertilizer switch is fixedly installed on the intermediate column 214. The closed block 216 is fan-shaped. The arc length of the closed block 216 exceeds the arc length of the sliding block 213. The closed block 216 is rotatably connected to the side of the sliding block 213 away from the storage tank 102. During the rotation of the closed block 216 The center of the intermediate column 214 is arranged on the axis of the intermediate column 214. The sliding block 213 is also provided with a plurality of stop columns 217. The stop columns 217 are used to stop the rotation of the closing block 216. After the closing block 216 rotates ninety degrees, it can cooperate with the sliding block 213 to completely isolate the dosage cylinder 201 from the storage tank 102. In the initial state, the closing block 216 overlaps with the sliding block 213 at least half of the sector area. In this state, the fertilizer in the storage tank 102 can enter the dosage cylinder 201 through the remaining gap. After the driving column 215 moves toward the storage tank 102, the driving column 215 will drive the intermediate column 214 to rotate through the rotating slide groove, and the intermediate column 214 will rotate with the closing block 216. When the closing block 216 rotates around the axis of the intermediate column 214 Figure 6 After rotating ninety degrees, the closed block 216 will contact another stop post 217 on the sliding block 213. At this time, the sliding block 213 and the closed block 216 will completely isolate the dosing cylinder 201 from the storage tank 102. This state is when the dosing cylinder 201 begins to release fertilizer into the pit, so that the fertilizer in a pit can be controlled.
[0023] like Figures 4 to 6As shown, a movable rod 211 is fixedly installed on the side of the sliding block 213 away from the storage tank 102, and the movable rod 211 is slidably connected to the dosage barrel 201. One end of the movable rod 211 connected to the sliding block 213 is arranged in the dosage barrel 201, and the other end of the movable rod 211 is arranged outside the dosage barrel 201. A sliding groove baffle is arranged on the movable rod 211, and the sliding groove baffle is in close contact with the inner wall of the dosage barrel 201 to prevent the fertilizer from falling out of the dosage barrel 201 from the movable rod 211. 01 is also rotatably mounted on the outer wall of the dosing cylinder 201, and the outer screw rod 210 is connected to the movable rod 211 by threads. An outer handle 209 is fixedly mounted on the outer screw rod 210. When the outer handle 209 is rotated, the movable rod 211 can be driven to slide on the dosing cylinder 201, and then the movable rod 211 drives the sliding block 213 and the closed block 216 to slide on the inner wall of the dosing cylinder 201, so that the storage space of the dosing cylinder 201 can be increased or decreased, and then the application amount of fertilizer in one hole can be increased or decreased.
[0024] Working principle: Here is an example of fertilizer dosage. For example, when planting tobacco seedlings, 34 grams of fertilizer is required for one hole of tobacco seedlings, and 40 tobacco seedlings need to be fertilized in one row or at one time. In this way, 1.4 kilograms of fertilizer can be stored in the storage tank 102, and the amount of fertilizer applied at one time in the dosage cylinder 201 must be adjusted. The inner handle 207 and the outer handle 209 are manually rotated. The rotation of the outer handle 209 can change the position of the sliding block 213 and the closing block 216 in the dosage cylinder 201. The rotation of the inner handle 207 is to allow the inner handle 207 to drive the adjusting screw 204, and the adjusting screw 204 drives the inner hollow cylinder 203 and the driving column 215 to move, so that the driving column 215 and the intermediate column 214 move in the same direction, so that the closing work of the closing block 216 on the device can be carried out normally.
[0025] When in use, the handle 101 and the storage tank 102 are manually held to move the device to the soil hole where tobacco is planted. Then, the protruding flat shovel 208 on the device is manually inserted into the soil to stabilize the device. After the protruding flat shovel 208 contacts the soil, the pressing ring 218 will also contact the soil. The protruding flat shovel 208 can more accurately confirm the fertilization position during the fertilization process to prevent the fertilizer from contacting the roots of the seedlings and thus damaging the growth of the seedlings. When releasing the fertilizer, the storage tank 102 and the dosage cylinder 201 are manually pressed to squeeze the pressing ring 218, and then the pressing ring 218 is pressed. The pressure ring 218 can drive the leakage stopper 205 and the driving column 215 to move toward the storage tank 102 through the stopper cylinder 202. At this time, the driving column 215 will first drive the intermediate column 214 and the closed stopper 216 to rotate, so that the closed stopper 216 can close the passage between the dosage cylinder 201 and the storage tank 102. After moving a predetermined distance, the leakage stopper 205 will break away from the contact with the outlet end of the dosage cylinder 201. When the leakage stopper 205 breaks away from the outlet end, the fertilizer will fall out of the device from the outlet end of the dosage cylinder 201 and then fall into the soil.
[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
