Description

Technical Field

[0001] This invention relates to a monitoring device, and more particularly to a crop growth monitoring device for agricultural Internet of Things (IoT) applications. Background Technology

[0002] As a major agricultural country, China has a vast range of crops cultivated, and numerous studies on crop improvement are constantly emerging. To ensure the healthy growth of crops and provide them with appropriate care, real-time monitoring is crucial, especially for trial crops in experimental fields.

[0073] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0074] Example 1

[0075] An agricultural Internet of Things (IoT) device for monitoring crop growth, such as Figure 1-6As shown, it includes support legs 1, a first rotating seat 2, a feeding plate 21, a first rotating block 3, a first bracket 4, a second rotating seat 5, a second rotating block 6, a first sliding rod 7, a first sliding sleeve 8, a first spring 9, a placement rack 10, a drive mechanism 11, and a clamping mechanism 12. The lower part of the first rotating seat 2 is evenly provided with six support legs 1. The upper part of the first rotating seat 2 is rotatably provided with a first rotating block 3. The upper side of the interior of the first rotating seat 2 is provided with a feeding plate 21. The right side of the outer wall of the first rotating seat 2 and the front and rear sides of the first rotating seat 2 are provided with first brackets 4. A second rotating seat 5 is connected to the upper part of the first bracket 4. A second rotating block 6 is rotatably provided at the lower part of the second rotating seat 5. A first sliding rod 7 is connected between the left side of the second rotating block 6 and the left side of the first rotating block 3. A first sliding sleeve 8 is slidably provided on the first sliding rod 7. A first spring 9 is wound on the first sliding rod 7. The first spring 9 is connected between the first sliding rod 7 and the first sliding sleeve 8. A placement frame 10 is provided at the lower right side of the first sliding sleeve 8. A driving mechanism 11 is connected between the second rotating seat 5 and the second rotating block 6. A clamping mechanism 12 is provided on the placement frame 10.

[0076] When crop growth needs to be monitored, this device can be used. The operator places the crop on the feeding plate 21, then operates the clamping mechanism 12. The operator then places the camera between the clamping mechanism 12 and the placement frame 10. The operator releases the clamping mechanism 12, which automatically resets and clamps the camera. The operator then opens the drive mechanism 11 and the camera. The drive mechanism 11 causes the second rotating block 6 to rotate, thereby causing the first sliding rod 7, the first sliding sleeve 8, the first spring 9, the placement frame 10, and the camera to move in a circular motion. The first sliding rod 7 drives the first rotating block 3 to rotate. The circular motion of the camera will provide preliminary monitoring and recording of crop growth. The operator then closes the drive mechanism 11, causing the second rotating block 6 to stop rotating, thus stopping the circular motion of the first sliding rod 7, the first sliding sleeve 8, the first spring 9, the placement frame 10, and the camera. The first sliding rod 7 drives the first rotating block 3 to stop rotating. The operator then turns off the camera, operates the clamping mechanism 12, removes the camera, and releases the clamping mechanism 12, which automatically resets. The operator repeats the above steps to achieve preliminary monitoring of crop growth.

[0077] The drive mechanism 11 includes a second bracket 111, a motor 112, a first rotating shaft 113 and a third bracket 114. The second rotating seat 5 is provided with the second bracket 111 at the top, the motor 112 is mounted on the upper part of the second bracket 111, the second rotating block 6 is provided with the third bracket 114 at the bottom, and the first rotating shaft 113 is provided in the middle of the third bracket 114. The first rotating shaft 113 is connected to the output shaft of the motor 112.

[0078] When crop growth needs to be monitored, the staff starts motor 112. The output shaft of motor 112 rotates, causing the first rotating shaft 113, the third support 114, and the second rotating block 6 to rotate. The second rotating block 6 causes the placement frame 10 and the camera to move in a circular motion. The circular motion of the camera will monitor and record the crop growth. After the crop growth monitoring is completed, the staff can turn off motor 112.

[0079] The clamping mechanism 12 includes a first pull rod 121, a clamping block 122, and a second spring 123. The clamping block 122 is slidably provided on the lower side of the placement frame 10. The first pull rod 121 is provided at the lower part of the clamping block 122. The second spring 123 is wrapped around both the front and rear sides of the clamping block 122. The second spring 123 is connected between the placement frame 10 and the clamping block 122.

[0080] When the camera needs to be clamped, the operator moves the first lever 121 downwards, causing the clamping block 122 to move downwards. The second spring 123 is stretched, and the operator places the camera between the clamping block 122 and the mounting bracket 10. Then, the operator releases the first lever 121, causing the second spring 123 to return to its original position. The second spring 123 causes the clamping block 122 and the first lever 121 to move upwards and return to their original position. The return of the clamping block 122 will clamp the camera, preventing it from falling to the ground and causing damage when monitoring crop growth. When the camera needs to be removed, the operator pulls the first lever 121 downwards, causing the clamping block 122 to move downwards. The second spring 123 is stretched, and the operator removes the camera. Then, the operator releases the first lever 121, causing the second spring 123 to return to its original position. The second spring 123 causes the first lever 121 and the clamping block 122 to move upwards and return to their original position.

[0081] Example 2

[0082] Based on Example 1, such as Figure 1 , Figure 2 and Figure 7-15As shown, it also includes a rotating mechanism 13, which includes a fourth bracket 131, a fixed shaft 132, a large gear 133, a screw 134, a small gear 135, a locking block 136, a second sliding sleeve 137, a second sliding rod 138, and a third spring 139. The fourth bracket 131 is provided on the lower side inside the second rotating seat 5. The fixed shaft 132 is provided in the middle of the fourth bracket 131. The fixed shaft 132 is rotatably connected to the first rotating shaft 113. The large gear 133 is provided at the lower part of the fixed shaft 132. The rotation is between the left side of the first rotating block 3 and the left side of the second rotating block 6. A screw 134 is connected in a movable manner. The screw 134 passes through the first sliding sleeve 8. A small gear 135 is provided on the upper part of the screw 134. The small gear 135 meshes with the large gear 133. A second sliding sleeve 137 is provided on both the front and rear sides of the upper part of the first sliding sleeve 8. A second sliding rod 138 is slidably provided on each of the two second sliding sleeves 137. A locking block 136 is connected between the right sides of the two second sliding rods 138. The locking block 136 contacts the screw 134. A third spring 139 is wound on the second sliding rod 138. The third spring 139 is connected between the second sliding rod 138 and the second sliding sleeve 137.

[0083] When the first rotating block 3 and the second rotating block 6 rotate, the rotation of the first rotating block 3 and the second rotating block 6 causes the screw 134, the first sliding rod 7, and the camera to move in a circular motion. The circular motion of the screw 134 causes the small gear 135 to move in a circular motion. At the same time, the small gear 135 is pushed and rotated by the large gear 133. The rotation of the screw 134 causes the locking block 136 to move upward, thereby causing the second sliding sleeve 137, the second sliding rod 138, the third spring 139, and the first sliding sleeve 8 to move upward. The upward movement of the first sliding sleeve 8 causes the placement frame 10 and the camera to move upward. The upward movement of the first sliding sleeve 8 compresses the first spring 9. At the same time, the camera moves in a circular motion. The circular motion and upward movement of the camera will provide comprehensive monitoring of crop growth. The measurement records the growth of crops. When the first sliding sleeve 8 moves upward to its limit, the worker pulls the locking block 136 to the right to prevent it from contacting the screw 134, thereby causing the second sliding rod 138 to move to the right. The third spring 139 is compressed. Due to gravity and the return of the first spring 9 which was in a compressed state, the first sliding sleeve 8 moves downward to reset. The first sliding sleeve 8 causes the placement frame 10, camera, second sliding sleeve 137, second sliding rod 138, third spring 139, and locking block 136 to move downward to reset. Then, the worker releases the locking block 136 to reset the third spring 139. The third spring 139 causes the locking block 136 and the second sliding rod 138 to move to the left to reset. The locking block 136 will then contact the screw 134.

[0084] It also includes a reset mechanism 14, which includes a first wedge block 141, a push block 142, a third slide rod 143, a magnet 144, and a fourth spring 145. The first slide rod 7 has a first wedge block 141 on its upper part and a push block 142 on its lower part. The placement rack 10 has third slide rods 143 on both the front and rear sides of its upper part. A magnet 144 is slidably connected between the two third slide rods 143. The push block 142 cooperates with the magnet 144, and the magnet 144 cooperates with the locking block 136. A fourth spring 145 is wound around the third slide rod 143 and is connected between the magnet 144 and the placement rack 10.

[0085] When the placement rack 10 moves upward, it causes the third slide bar 143, magnet 144, and fourth spring 145 to move upward. Magnet 144 moves upward until it is no longer in contact with the push block 142. The stretched fourth spring 14 returns to its original position, causing magnet 144 to move downward to the same horizontal plane as the locking block 136. When the locking block 136 moves upward to contact the first wedge block 141, it continues to move upward and is squeezed to the right by the first wedge block 141. The rightward movement of the locking block 136 drives the second slide bar 138 to move to the right, compressing the third spring 139. The locking block 136 continues to move to the right until it contacts the magnet 144. Due to magnetic attraction, the magnet... Iron 144 attracts the locking block 136, and the first spring 9, which is in a compressed state, returns to its original position. This causes the first sliding sleeve 8, the placement bracket 10, the third sliding rod 143, the magnet 144, and the fourth spring 145 to move downwards and return to their original positions. The magnet 144 is pushed and supported by the push block 142 as it moves downwards. The third sliding rod 143 continues to move downwards, causing the fourth spring 145 to be stretched. When the locking block 136 continues to move downwards until it no longer contacts the magnet 144, the third spring 139, which is in a compressed state, returns to its original position, causing the locking block 136 and the second sliding sleeve 137 to move to the left and return to their original positions. The return of the locking block 136 will again adaptively stabilize the screw 134, thus achieving the goal of moving the locking block 136 to the right without manual pushing, saving manpower.

[0086] It also includes a spraying mechanism 15, which includes a water tank 151, a nozzle 152, a clogging ball 153, a second lever 154, a threaded cap 155, and a torsion spring 156. The water tank 151 is located in the middle of the bottom of the third bracket 114. The nozzle 152 is located in the middle of the lower part of the water tank 151. The clogging ball 153 is rotatably mounted on the nozzle 152. The second lever 154 is located on the rear right side of the clogging ball 153. The threaded cap 155 is threaded on the upper left side of the water tank 151. The torsion spring 156 is wound around the clogging ball 153. The torsion spring 156 connects the nozzle 152 and the clogging ball 153.

[0087] When crops need watering, the worker turns the threaded cap 155 to open it, pouring an appropriate amount of water into the water tank 151. Then, the worker turns the threaded cap 155 in the opposite direction to close it, and the water in the water tank 151 flows into the nozzle 152. The water in the nozzle 152 is then sprayed onto the crops, achieving rapid irrigation. When the crops no longer need watering, the worker turns the second lever 154, which causes the blocking ball 153 to rotate until it blocks the nozzle 152. The torsion spring 156 deforms, and the water in the nozzle 152 stops spraying. When the crops need watering again, the worker releases the second lever 154, causing the torsion spring 156 to return to its original position. The torsion spring 156 then causes the blocking ball 153 to rotate in the opposite direction until it no longer blocks the nozzle 152, and the nozzle 152 sprays water onto the crops. The blocking ball 153 then causes the second lever 154 to rotate in the opposite direction to return to its original position.

[0088] It also includes a pushing mechanism 16, which includes a fifth bracket 161, a second wedge block 162 and a fifth spring 163. The fifth bracket 161 is provided on the upper right rear side of the water tank 151. The second wedge block 162 is slidably provided on the fifth bracket 161. The second wedge block 162 cooperates with the large gear 133 and the second hand lever 154. The fifth spring 163 is connected between the fifth bracket 161 and the second wedge block 162.

[0089] The rotation of water tank 151 and nozzle 152 causes the fifth bracket 161, second wedge block 162, and fifth spring 163 to rotate synchronously. When the second wedge block 162 rotates and contacts the large gear 133, the large gear 133 pushes the second wedge block 162 downward, stretching the fifth spring 163. The downward movement of the second wedge block 162 drives the second pull rod 154 to rotate, thereby causing the blocking ball 153 to rotate until it blocks the nozzle 152. The torsion spring 156 deforms, stopping the water in the nozzle 152. To stop the flow, the blocking ball 153 does not need to be manually rotated. When the second wedge block 162 rotates to a position where it is no longer in contact with the large gear 133, the fifth spring 163 resets, causing the second wedge block 162 to move upwards and reset to a position where it is no longer in contact with the second hand lever 154. The torsion spring 156, which is in a state of deformation, resets, causing the blocking ball 153 to rotate in the opposite direction and not block the nozzle 152. The water in the nozzle 152 will be sprayed onto the crops to achieve intermittent spraying. The second wedge block 162 drives the second hand lever 154 to rotate in the opposite direction and reset.
