Description

Technical Field

[0001] This utility model relates to the field of soil pH testing devices, and in particular to a soil pH testing device for seedling planting. Background Technology

[0002] Most seedlings grow best in soil with a specific pH range. Soil that deviates from the optimal pH range may damage root health, growth and development, and nutrient absorption. Therefore, soil pH testing devices are used to test the soil before planting to help with subsequent planting.

[0003] An existing patent (publication number: CN221506913U) discloses "This utility model provides a soil pH testing device, relating to the field of soil testing technology. It includes a housing, with a motor fixedly installed on the inner wall of one side of the housing. A crank is fixedly installed at the output end of the motor, and a rocker arm is rotatably connected to the outer surface of the crank via a bearing. In this utility model, the insertion rod is vertically placed on the soil surface. The motor is started, and through the interaction of the crank, rocker arm, and connecting rod, the striking block moves up and down repeatedly, colliding with the connecting block and generating an impact force. Under the action of this impact force, the pointed end of the insertion rod strikes the ground, creating a hole. When the impact energy of the downward movement of the insertion rod is completely dissipated, the connecting block moves upward under the action of the spring contraction force, and the striking block strikes it again, causing the insertion rod to move downward again and impact the ground. Through repeated impacts on the ground, the insertion rod can be inserted into deeper layers of soil. The operation is simple, time-saving, and labor-saving."

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: When the device drills holes in the ground, because its through holes are exposed, the repeated impact of drilling will cause soil to enter through the through holes. Once soil enters a region, it is difficult to clean it. When testing in other regions, it will have a great impact on the measurement of acidity and alkalinity. Its measurement accuracy and internal cleanliness are difficult to guarantee.

[0005] Therefore, those skilled in the art have provided a device for detecting the pH of soil for seedling planting to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a soil pH testing device for seedling planting. This device has a better protection mechanism for the pH probe, and soil is difficult to enter through the through hole during the drilling process, thus ensuring measurement accuracy and internal cleanliness.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a seedling planting soil pH testing device, comprising a handheld box, a processing mechanism disposed on one side inside the handheld box, a storage battery disposed at the rear inside the handheld box, a power mechanism disposed on the other side inside the handheld box, a punching mechanism slidably disposed through the lower end inside the handheld box, a protective mechanism disposed at the lower end inside the punching mechanism, the protective mechanism comprising a movable body, protective shells slidably disposed through both sides inside the movable body, rack blocks fixedly disposed at the upper ends of both protective shells, a rotating rod rotatably disposed between the upper and lower ends of the movable body, a gear fixedly sleeved around the rotating rod near the two rack blocks, a rotating block fixedly sleeved around the rotating rod near the upper part of the movable body, an upper disc rotatably sleeved around the rotating rod near the middle, a No. 1 spring disposed on both the front and rear sides of the lower end of the upper disc, and a cylindrical sleeve fixedly disposed near the edge of the lower end of the upper disc;

[0008] The punching mechanism includes a punching housing and multiple No. 2 springs. A fixed plate is installed through the lower part of the punching housing. Grooves are fixedly installed at the front and rear of the lower end of the fixed plate. Sliding grooves are opened on both sides of the punching housing at the lower part.

[0009] Furthermore, the two rack blocks are located at the front and rear of the gear, respectively. The rack block at the front is fixedly connected to the upper end of the protective shell on one side, and the rack block at the rear is fixedly connected to the upper end of the protective shell on the other side.

[0010] Furthermore, both rack blocks are meshed with gears, the lower end of the gears contacts the upper surface of the protective shell, and a limiting post is fixedly sleeved on the part of the rotating rod located above the gear and between the upper end of the moving body.

[0011] Furthermore, the rotating rod extends through to the top of the handheld box, and a turntable is fixedly installed at the upper end of the rotating rod. Two limiting blocks are provided at the upper end of the handheld box near the turntable, and a protrusion is fixedly installed on one side of the turntable. The included angle between the two limiting blocks is 90°.

[0012] Furthermore, the upper disc is rotatably mounted around the rotating rod, and the upper disc is slidably mounted in the grooves on both sides inside the perforated outer shell.

[0013] Furthermore, the cylindrical sleeve is slidably disposed inside the fixed disk, with the lower end of the cylindrical sleeve contacting the upper end of the protective shell, and the cylindrical sleeve completely covering the sliding grooves on both sides.

[0014] Furthermore, multiple second springs are disposed between the upper bottom of the handheld box and the lower top of the perforated outer shell.

[0015] Furthermore, a detection mechanism is provided at the lower end of the interior of the perforated housing, and a through hole is provided on one side of the lower end of the perforated housing. The detection mechanism consists of an electric push rod and a pH probe.

[0016] This utility model has the following beneficial effects:

[0017] 1. The present invention proposes a soil pH testing device for seedling planting. During the drilling process, the protective shells on both sides are tightly attached to the lower part of the drilled outer shell. At this time, the through hole is completely blocked and sealed. Under repeated impact, the soil inside will not enter the interior through the through hole. After a measurement is performed at one point, the soil at that point will not remain inside and affect the next measurement. This can greatly improve the measurement accuracy and effectively improve the cleanliness of the interior.

[0018] 2. This utility model proposes a soil pH testing device for seedling planting. After drilling to a specified depth, the device can rotate a rotating rod externally. At this time, the gears can move the two rack blocks to the sides with the corresponding protective shells. Under the restriction of the limiting block, after the rotating rod rotates 90° counterclockwise, the rotating block will enter the groove between the two groove blocks. Under the reset action of the No. 1 spring, the two protective shells can move upward along the sliding groove. At this time, the testing work can be carried out. The drilling work does not require manual force, and the operation can be easily controlled from the outside, which has good convenience. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 and Figure 5 An embodiment of this utility model provides a seedling planting soil pH testing device, including a handheld box 3, a processing mechanism 4 is provided inside the handheld box 3 on one side, a storage battery 6 is provided inside the handheld box 3 at the rear, a power mechanism 8 is provided inside the handheld box 3 on the other side, a punching mechanism 2 is slidably provided through the lower end of the handheld box 3, a protective mechanism 1 is provided inside the punching mechanism 2 at the lower part, and a push block 7 is fixedly provided at the upper end of the punching mechanism 2 on the other side.

[0028] Specifically, the power mechanism 8 can make the drilling mechanism 2 reciprocate up and down through the push block 7 to facilitate drilling. The battery 6, the power mechanism 8 and the processing mechanism 4 are all electrically connected. After the bottom of the drilling mechanism 2 is inspected, the inspection data can be uploaded to the processing mechanism 4.

[0029] Reference Figure 2 , Figure 3 and Figure 4The protective mechanism 1 includes a movable body 101. Protective shells 102 are slidably disposed through both sides inside the movable body 101. Rack blocks 103 are fixedly disposed at the upper ends of both protective shells 102. A rotating rod 105 is rotatably disposed between the upper and lower ends of the movable body 101. Gears 104 are fixedly sleeved around the rotating rod 105 near the two rack blocks 103. A rotating block 106 is fixedly sleeved around the rotating rod 105 near the upper part of the movable body 101. An upper disc 107 is rotatably sleeved around the rotating rod 105 near the middle. A No. 1 spring 108 is disposed at the lower end of the upper disc 107 near both the front and rear sides. A cylindrical sleeve 109 is fixedly disposed at the lower end of the upper disc 107 near the edge.

[0030] Two rack blocks 103 are located at the front and rear of the gear 104 respectively. The rack block 103 at the front is fixedly connected to the upper end of the protective shell 102 on one side, and the rack block 103 at the rear is fixedly connected to the upper end of the protective shell 102 on the other side. Both rack blocks 103 are meshed with the gear 104. The lower end of the gear 104 is in contact with the upper surface of the protective shell 102. The part of the rotating rod 105 between the gear 104 and the upper end of the moving body 101 is fixedly fitted with a limiting post. The upper disc 107 is rotatably mounted on the rotating rod 105. The upper disc 107 is slidably mounted in the grooves on both sides inside the perforated outer shell 201. The cylindrical sleeve 109 is slidably mounted inside the fixed disc 205. The lower end of the cylindrical sleeve 109 is in contact with the upper end of the protective shell 102. The cylindrical sleeve 109 completely covers the sliding grooves 206 on both sides.

[0031] Specifically, both protective shells 102 can fit tightly against the lower part of the perforated outer shell 201. The curvature design of their bodies is conducive to drilling. The protrusion on the upper turntable of the rotating rod 105 cooperates with the two limiting blocks 5 to limit the angle of each rotation to between 0° and 90°, which is convenient for operation. The rotating block 106 is rectangular. When both protective shells 102 close the through hole 203, the rotating block 106 is located at the lower end of the two groove blocks 204. At this time, the rotating block 106 is perpendicular to the groove between the two groove blocks 204 and cannot move upward. The rotation of the rotating rod 105 will not cause the moving body 101 and the upper disc 107 to rotate. The upward movement of the rotating rod 105 will cause the moving body 101 and the upper disc 107 to move upward together.

[0032] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 The punching mechanism 2 includes a punching housing 201 and multiple second springs 207. A fixed plate 205 is provided through the lower part of the punching housing 201. A groove block 204 is fixedly provided at the front and rear of the lower end of the fixed plate 205. Slide grooves 206 are provided on both sides of the punching housing 201 at the lower part.

[0033] Multiple No. 2 springs 207 are located between the bottom upper end of the handheld box 3 and the top lower end of the perforated outer shell 201. A detection mechanism 202 is located inside the lower end of the perforated outer shell 201. A through hole 203 is opened on one side of the lower end of the perforated outer shell 201. The detection mechanism 202 consists of an electric push rod and a pH probe.

[0034] Specifically, the movable body 101 and the rotating block 106 can move between the two recessed blocks 204. The electric push rod of the detection mechanism 202 can push the pH probe out of the through hole 203 to the outside. They are all controlled by the processing mechanism 4. The fixed plate 205 and the two recessed blocks 204 cannot move upward.

[0035] Reference Figure 5 The power mechanism 8 includes a motor 801. A first rotating plate 802 is rotatably arranged at the output end of the motor 801. A second rotating plate 803 is rotatably arranged on one side of the first rotating plate 802. The lower end of the second rotating plate 803 is rotatably arranged on the upper end of the push block 7.

[0036] Specifically, the rotation of the motor 801 shaft can drive the push block 7 to move up and down reciprocally through the first rotating plate 802 and the second rotating plate 803, which can effectively impact the soil to complete the drilling work.

[0037] Working principle: When using this device, the drilling mechanism 2 can be aligned with the position to be drilled. Then, the processing mechanism 4 controls the motor 801 to start. At this time, the rotation of the motor 801 shaft will cause the push block 7 to drive the drilling mechanism 2 to move up and down reciprocally through the first rotating plate 802 and the second rotating plate 803. Under the action of the second spring 207, a rapid and stable impact on the soil can be achieved, and rapid drilling can be performed. As the drilling mechanism 2 moves down, under the cover of the two protective shells 102, the loose soil will not enter the drilling shell 201 through the through hole 203. When the drilling reaches the designated position, the rotating rod can be rotated. 105. The rotation of the rotating rod 105 will cause the rack blocks 103 at the front and rear, along with the corresponding protective shells 102, to move to both sides through the gear 104. After the rotating rod 105 rotates 90° under the restriction of the two limit blocks 5, the rotating block 106 can also rotate 90°. At this time, the rotating block 106 and the moving body 101 will move upward between the two groove blocks 204 under the reset action of the first spring 108. At this time, the two protective shells 102 will move upward along the slide 206. Then, the electric push rod of the detection mechanism 202 can be controlled to push the pH probe out of the through hole 203 for soil testing.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
