Description

Technical Field

[0001] This utility model relates to the field of tobacco planting technology, and in particular to a field tobacco plant count recording device. Background Technology

[0002] Tobacco plants refer to the plant parts harvested after the tobacco plant has grown, which are used for processing and producing tobacco products. Tobacco plants include the leaves, stems, roots, etc., but usually the most important part refers to the leaves. These leaves are processed through drying, fermentation, and other processes to make tobacco products such as cigarettes and cigars.

[0003] In the process of tobacco planting and management, accurately recording the number of tobacco plants in the field and their growth status is a fundamental and crucial task. It is directly related to many important aspects of tobacco planting, such as cost accounting, yield forecasting, quality assessment, and subsequent production decisions. Accurate plant count records help tobacco farmers to rationally allocate planting resources, such as the amount of fertilizer and pesticides used, and also provide reliable data for tobacco companies' procurement and statistics.

[0004] Recording the number of tobacco plants requires farmers to manually count each plant using a counter. However, prolonged use of this counter can cause arm pain and hand tremors when pressing the counting button, leading to inaccurate counts. Furthermore, because farmers need to hold the counter, they cannot monitor the current growth status of the plants while counting them. Farmers must record the plant count first, and then record the plant's production status, further increasing their workload.

[0005] Therefore, there is an urgent need for a field tobacco plant count recording device to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to provide a field tobacco plant count recording device that can solve the problems of existing methods that require tobacco farmers to hold a counter when recording the number of tobacco plants. This is because tobacco farmers may press the counting button too many times or not press it properly due to arm pain, resulting in inaccurate counts. At the same time, because tobacco farmers hold the counter, they cannot record the growth status of tobacco plants while counting, and they need to record the status of tobacco plants again after the counting is completed, which increases the workload.

[0014] As a preferred technical solution for a field tobacco plant count recording device, the counter is provided with a first locking part, and the connecting seat is provided with a second locking part. The first locking part and the second locking part can be plugged into each other. One of the first locking part and the second locking part is a locking post, and the other is a locking groove.

[0015] The fastener has a protrusion, and the protrusion has a third snap-fit ​​part, which can be inserted into the first snap-fit ​​part.

[0016] As a preferred technical solution for the field tobacco plant count recording device, the first locking part is a locking groove, the second locking part and the third locking part are both locking posts, and the second locking part and the third locking part are both provided with spring pieces.

[0017] As a preferred technical solution for a field tobacco plant count recording device, the recovery component includes a housing, a rotating assembly, and a spiral spring. The rotating assembly and the spiral spring are placed inside the housing. The rotating assembly includes a take-up shaft that can rotate relative to the housing. One end of the strap is wound and connected to the take-up shaft. One end of the spiral spring is connected to the inner wall of the housing, and the other end is connected to the take-up shaft.

[0018] As a preferred technical solution for the field tobacco plant count recording device, the rotating assembly further includes two support members, which are placed opposite each other inside the housing, and the winding shaft passes through the two support members.

[0019] As a preferred technical solution for a field tobacco plant count recording device, one end of the take-up shaft extends out of the housing, the positioning component includes a positioning cap and an insert, the positioning cap is placed at the end of the take-up shaft that extends out of the housing, the positioning cap is provided with a plurality of positioning grooves at intervals, and the insert is fixedly set on the fixing component and can be selectively inserted into the positioning groove.

[0020] As a preferred technical solution for a field tobacco plant count recording device, the fixing member is provided with an installation groove, which is located on the side of the positioning cap opposite to the positioning groove. The insert includes a guide post, a second elastic member, a first connecting post, and a second connecting post. The guide post is fixedly placed on the side wall of the installation groove and faces the positioning cap. The first connecting post is movably disposed on the guide post and faces the positioning groove. The second connecting post is connected to the first connecting post and faces the positioning groove. The second connecting post can be inserted into the positioning groove. The second elastic member is placed between the side wall of the installation groove and the first connecting post.

[0021] As a preferred technical solution for the field tobacco plant count recording device, the cross-sectional shape of the fixing member is semi-circular, the recycling member is placed on one side of the opening of the fixing member and connected to one end of the binding strap, and the other end of the binding strap is connected to the other side of the opening of the fixing member.

[0022] Compared with the prior art, the field tobacco plant count recording device provided by this utility model has the following technical advantages:

[0023] 1. By allowing both the connector and the fastener to snap onto the counter, the connector and the wearing mechanism can be selectively snapped onto the counter. The simple snap-fit ​​structure facilitates easy installation and removal of the connector and counter, or the wearing mechanism and counter, by tobacco farmers. When recording the number of tobacco plants, farmers can snap the main body onto the wearing mechanism and wear the counter on their wrist. This avoids arm pain caused by prolonged hand-holding of the counter, and prevents inaccurate counting due to excessive or insufficient pressing of the counting button. Furthermore, when farmers need to record the growth status of the tobacco plants while counting, this design is suitable for situations where farmers need to record the growth status of the tobacco plants. In this setup, tobacco farmers can connect the counter to the connector. When the farmer reaches a tobacco plant, they can insert a ground stake in front of the plant. The contact plate in the movable rod engages with the counter's counting button. As the farmer inserts the stake, the movable rod moves closer to the counter, the contact plate presses the counting button, and the counter counts once. When the farmer pulls out the stake, the movable rod resets relative to the stake, and the counting button resets, without affecting the counter's next count. This allows farmers to record the number of tobacco plants and their growth status simultaneously, without needing to operate the counter themselves, thus reducing the difficulty of operation for farmers.

[0024] 2. By connecting one end of the strap in the wearing mechanism to the recycling component and the other end to the fixing component, the wrist can be inserted between the strap and the fixing component. The extension length of the strap is locked by the positioning component, which can prevent the wearing mechanism from falling off the tobacco farmer's wrist when the tobacco farmer rotates his wrist. This makes the design of the wearing mechanism more reasonable and easier for tobacco farmers to carry the field tobacco plant count recording device. Attached Figure Description

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0042] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0044] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0045] like Figures 1 to 5As shown in the illustration, this embodiment provides a field tobacco plant count recording device, including a counter 1, a connector 2, and a wearing mechanism 3. The connector 2 includes a connecting seat 21, a ground nail post 22, and a movable rod 23. The connecting seat 21 is snapped into the counter 1. Tobacco farmers can install or remove the connector 2 from the counter 1 according to their needs. When tobacco farmers need to count the number of tobacco plants and record their growth status, they can install the connector 2 into the counter 1. A counting button 11 is provided at the bottom of the counter 1. The ground nail post 22 is connected to the connecting seat 21. The movable rod 23 can move along the length of the ground nail post 22. The movable rod 23 includes a contact post 231 and a contact plate 232 that are perpendicular to each other, and both the contact post 231 and the contact plate 232 are partially exposed outside the ground nail post 22. When the connecting seat 21 is snapped into the counter 1, the contact plate 232 is in contact with the counting button 11. Specifically, the contact post 231 is movably positioned on the ground nail post 22 and is parallel to the ground nail post 22. When the worker inserts the ground nail post 22 into the field, the contact post 231 moves closer to the counter 1, and the contact plate 232 presses the counting button 11, causing the counter 1 to complete one count. Thus, when a tobacco farmer inserts the ground nail post 22 in front of the corresponding tobacco plant, the counter 1 counts once, effectively reducing the farmer's operational difficulty. Simultaneously, after inserting the ground nail post 22 into the field, the farmer's hands are freed, allowing them to record the growth status of the tobacco plant immediately, eliminating the need for the farmer to record the growth status after completing the tobacco plant counting, effectively reducing the farmer's workload. The movable rod 23 can automatically reset relative to the ground nail post 22; that is, when the farmer removes the ground nail post 22 from the field, the movable rod 23 automatically resets, and the counting button 11 resets, without affecting the next count of the counter 1, effectively reducing the farmer's operational difficulty.

[0046] The wearing mechanism 3 includes a fixing component 31, a strap 32, a retraction component 33, and a positioning component 34. The fixing component 31 can be snapped into the counter 1, meaning the wearing mechanism 3 can be snapped into the counter 1. When the tobacco farmer only needs to count the tobacco plants, the farmer can choose to snap the counter 1 into the wearing mechanism 3. At this time, the counter 1 is fixed on the farmer's wrist, which effectively solves the problem that the farmer's arm is sore from holding the counter 1 for a long time, and the hand shakes when pressing the counting button 11, resulting in inaccurate counting of tobacco plants. At the same time, the snapping structure is relatively simple, making it easy for staff to disassemble and install the counter 1 and the wearing mechanism 3, reducing the assembly difficulty for the tobacco farmer. The strap 32, the retraction component 33, and the positioning component 34 are all set on the fixing component 31. One end of the strap 32 is wrapped and connected to the retraction component 33, and the other end is connected to the fixing component 31, specifically a fixed connection. The retraction component 33 can retract the strap 32. When a tobacco farmer wants to wear the counter 1, they simply pull the strap 32 and then insert their wrist between the strap 32 and the fixing member 31. Because the retracting member 33 retracts the strap 32, even if the farmer pulls it out excessively, the strap 32 will retract under the action of the retracting member 33, making the strap 32 fit snugly against the farmer's wrist. Different tobacco farmers have different wrist sizes. Because the strap 32 and the retracting member 33 are intertwined, the extension length of the strap 32 is adjustable to fit different wrist sizes, improving the versatility of the wearing mechanism 3. The positioning member 34 can lock the extension length of the strap 32 relative to the retracting member 33. After adjusting the extension length of the strap 32 according to their own wrist size, the farmer can lock the extension length of the strap 32 through the positioning member 34 to prevent the wearing mechanism 3 and the counter 1 from falling off the farmer's wrist when they rotate their wrist.

[0047] The field tobacco plant counting device provided in this embodiment allows both the connecting seat 21 and the fixing member 31 to be snapped into the counter 1. This allows the connecting member 2 and the wearing mechanism 3 to be selectively snapped into the counter 1. Due to the simple snap-fit ​​structure, it is easy for tobacco farmers to install and remove the connecting member 2 and the counter 1, or the wearing mechanism 3 and the counter 1. When only the number of tobacco plants needs to be recorded, the tobacco farmer can snap the counter 1 into the wearing mechanism 3 and wear the counter 1 on their wrist. This avoids arm pain caused by holding the counter 1 for a long time, and prevents inaccurate counting of tobacco plants due to excessive or insufficient pressing of the counting button 11. When the tobacco farmer needs to record the growth of tobacco plants while counting, the device can also be used for other purposes. In this situation, the tobacco farmer can connect the counter 1 to the connector 2. When the farmer reaches the position of a tobacco plant, he can insert the ground nail post 22 in front of the corresponding tobacco plant. The contact plate 232 in the movable rod 23 is in contact with the counting button 11 of the counter 1. When the farmer inserts the ground nail post 22 into the field, the movable rod 23 moves towards the counter 1, and the contact plate 232 presses the counting button 11, causing the counter 1 to count once. When the farmer pulls out the ground nail post 22, the movable rod 23 can reset relative to the ground nail post 22, and the counting button 11 resets, without affecting the next count of the counter 1. This allows the farmer to record the number of tobacco plants and their growth status at the same time, without needing to operate the counter 1, thus reducing the difficulty of operation for the farmer.

[0048] By connecting one end of the strap 32 in the wearing mechanism 3 to the retrieval component 33 and the other end to the fixing component 31, the wrist can be inserted between the strap 32 and the fixing component 31. The extension length of the strap 32 is locked by the positioning component 34, which can prevent the wearing mechanism 3 from falling off the tobacco farmer's wrist when the tobacco farmer rotates his wrist. This makes the design of the wearing mechanism 3 reasonable and more convenient for tobacco farmers to carry the field tobacco plant count recording device.

[0049] The counting principle of the counter 1 in this embodiment is as follows: pressing the counting button 11 once completes one count. It is a conventional counting component. Its working principle and specific structure can be referred to the existing technology, and will not be described in detail here.

[0050] The ground nail post 22 and the connecting seat 21 can be fixed together by bolts, glue, or snap-fit ​​post and slot. No specific restrictions are placed on the connection method between the ground nail post 22 and the connecting seat 21.

[0051] Exemplarily, the ground nail post 22 includes a guide groove 221 extending along its length and a clearance groove 222 communicating with the guide groove 221. A contact post 231 is movably positioned in the guide groove 221 and partially exposed thereout. A contact plate 232 is connected to the end of the contact post 231 near the connecting seat 21. The contact plate 232 is located within the clearance groove 222. When a tobacco farmer inserts the ground nail post 22 into the field, the contact post 231 moves along the guide groove towards the counter 1, causing the contact plate 232 to press the counting button 11, thus completing one count for the counter 1. In another embodiment, a guide rail can be provided on the ground nail post 22, and a slider can be provided on the contact post 231. The movable rod 23 is movably positioned on the ground nail post 22 via the guide rail and slider. When the tobacco farmer inserts the ground nail post 22 into the field, the contact plate 232 presses the counting button 11, causing the counter 1 to complete one count.

[0052] Furthermore, the movable rod 23 also includes a first elastic element 233. One end of the first elastic element 233 is connected to the contact plate 232, specifically to the side of the contact plate 232 facing the counter 1, and the other end of the first elastic element 233 is connected to the inner wall of the clearance groove 222 facing the contact plate 232. In another embodiment, one end of the first elastic element 233 is connected to the side of the contact plate 232 facing the counter 1, and the other end can be connected to the bottom surface of the connecting seat 21. When the tobacco farmer inserts the ground nail post 22 into the field, the movable rod 23 moves towards the counter 1. At this time, the first elastic element 233 is compressed. When the tobacco farmer removes the ground nail post 22 from the field, the force of the soil on the movable rod 23 is removed. Under the action of the first elastic element 233, the movable rod 23 can move relative to the ground nail post 22 and then reset. At this time, the contact plate 232 no longer presses against the counting button 11 so that the counter 1 can perform the next count. In this embodiment, the first elastic element 233 can be a spring or a spiral spring sheet, and no specific limitation is made here.

[0053] In this embodiment, a first latching portion 12 is provided on one side of the counter 1, and a second latching portion 211 is provided on the connecting seat 21. The first latching portion 12 and the second latching portion 211 can be inserted into each other, thus enabling the counter 1 to be latched and connected to the connecting member 2. Furthermore, a protrusion 311 is provided on the fixing member 31, and a third latching portion 312 is provided on the protrusion 311. The third latching portion 312 and the first latching portion 12 can be inserted into each other, so that the fixing member 31 and the counter 1 are latched and connected, thereby enabling the wearing mechanism 3 to be latched and connected to the counter 1.

[0054] The first engaging part 12 is a slot, while the second engaging part 211 and the third engaging part 312 are both engaging posts. When assembling the counter 1 and the connector 2, or assembling the counter 1 and the wearing mechanism 3, the engaging post can be inserted into the slot to complete the engagement between the counter 1 and the connector 21, or between the counter 1 and the wearing mechanism 3. The slot can restrict the engaging post, preventing it from falling out. Furthermore, both the second engaging part 211 and the third engaging part 312 are provided with spring pieces 4; that is, spring pieces 4 are provided on the engaging posts on the connector 21 and the fastener 31. When the engaging post is inserted into the slot, the spring piece 4 abuts against the inner wall of the slot. The spring piece 4 prevents the engaging post from shaking within the slot, ensuring a secure assembly of the counter 1 and the connector 2, or the counter 1 and the wearing mechanism 3. In this case, the opening of the spring piece 4 relative to the locking post faces upward, so that the tobacco farmer can smoothly insert the locking post from the top of the locking groove into the locking groove.

[0055] Preferably, two spaced-apart first latching portions 12 can be provided on the counter 1, two spaced-apart second latching portions 211 can be provided on the connecting seat 21, and two spaced-apart third latching portions 312 can be provided on the fixing member 31. This can further improve the stability of the assembly between the counter 1 and the connecting seat 21, as well as the stability of the assembly between the counter 1 and the wearing mechanism 3.

[0056] In this embodiment, the counter 1, the connector 2, and the wearing mechanism 3 can also be connected by a snap-fit ​​mechanism, and no specific restrictions are imposed here.

[0057] For example, such as Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the recycling component 33 includes a housing 331, a rotating assembly 332, and a spiral spring 333, which are housed within the housing 331. The rotating assembly 332 includes a winding shaft 3321, which is rotatable relative to the housing 331. One end of the strap 32 is wound around the winding shaft 3321, and the other end is connected to the fixing member 31. One end of the spiral spring 333 is connected to the inner wall of the housing 331, and the other end is connected to the winding shaft 3321. When the tobacco farmer pulls the strap 32, the winding shaft 3321 rotates forward, causing the spiral spring 333 to deform. The tobacco farmer can then insert their wrist between the strap 32 and the fixing member 31, allowing the wearing mechanism 3 to adapt to wrists of different sizes. When the tobacco farmer stops pulling the strap 32, the spiral spring 333 is no longer under external force and returns to its original position. The winding shaft 3321 then rotates in the opposite direction, causing the strap 32 to retract and fit snugly against the tobacco farmer's wrist, thus improving the design rationality of the wearing mechanism 3. Specifically, when the strap 32 is released, the winding shaft 3321 rotates in the forward direction; when the strap 32 retracts, the winding shaft 3321 rotates in the reverse direction.

[0058] Furthermore, the rotating assembly 332 also includes two support members 3322, which are disposed opposite to each other within the housing 331, and the take-up shaft 3321 passes through the two support members 3322. The two support members 3322 support the take-up shaft 3321, allowing it to rotate. Furthermore, each of the two support members 3322 has mounting holes, which are opposite to each other, and each mounting hole contains a bearing. The two sides of the take-up shaft 3321 are respectively fixed to the inner rings of the two bearings. The bearings further improve the stability of the rotation of the take-up shaft 3321.

[0059] Furthermore, one end of the take-up shaft 3321 extends out of the housing 331. The positioning member 34 includes a positioning cap 341 and an insert 342. The positioning cap 341 is located at the end of the take-up shaft 3321 that extends out of the housing 331. Multiple positioning grooves 3411 are spaced apart on the positioning cap 341. The insert 342 is fixedly mounted on the fixing member 31 and can be selectively inserted into the positioning grooves 3411. When the tobacco farmer inserts his wrist between the strap 32 and the fixing member 31 and releases the strap 32 so that the strap 32 fits against his wrist, the insert 342 can be inserted into the positioning groove 3411. Since the insert 342 is fixed to the fixing member 31, when the insert 342 is inserted into the positioning groove 3411, it can restrict the rotation of the take-up shaft 3321. At this point, no matter how the tobacco farmer rotates his wrist, the strap 32 cannot extend, thus locking the strap 32 and securing the wearing mechanism 3 firmly on the tobacco farmer's wrist, thereby ensuring the tobacco farmer wears the counter 1 securely and preventing the counter 1 from falling off. Multiple positioning slots 3411 can be spaced apart on the circumference of the positioning cap 341, with the insert 342 correspondingly positioned on one side of the circumference of the positioning cap 341. Alternatively, the multiple positioning slots 3411 can also be arranged around the end face of the positioning cap 341, with the insert 342 facing the end face of the positioning cap 341.

[0060] Furthermore, a mounting groove 313 is provided on the fixing member 31. The mounting groove 313 is located on the side opposite to the positioning groove 3411 in the positioning cap 341. That is, when multiple positioning grooves 3411 are spaced apart on the circumferential surface of the positioning cap 341, the mounting groove 313 is located on one side of the circumferential surface of the positioning cap 341. When multiple positioning grooves 3411 are arranged around the end face of the positioning cap 341, the mounting groove 313 is located on one side of the end face of the positioning cap 341. The insert 342 includes a guide post 3421, a second elastic member 3422, a first connecting post 3423, and a second connecting post 3424. The guide post 3421 is fixedly placed on the side wall of the mounting groove 313 and faces the positioning cap 341. The first connecting post 3423 is movably disposed on the guide post 3421, so the first connecting post 3423 can move closer to or away from the positioning cap 341 along the guide post 3421. The second connecting post 3424 is connected to the first connecting post 3423 and is opposite to the positioning groove 3411. The first connecting post 3423 and the second connecting post 3424 are vertically connected. When the first connecting post 3423 moves along the guide post 3421, the second guide post 3421 can be inserted into or away from the positioning groove 3411, so that the insert 342 can be selectively inserted into the positioning groove 3411 and the extension length of the strap 32 is locked. The second elastic element 3422 is positioned between the side wall of the mounting groove 313 and the first connecting post 3423. When the tobacco farmer needs to adjust the extension length of the strap 32, the first connecting post 3423 can be moved away from the positioning cap 341. At this time, the second connecting post 3424 disengages from the positioning groove 3411, and the second elastic element 3422 is compressed. After the tobacco farmer has adjusted the extension length of the strap 32, they only need to loosen the first connecting post 3423. Under the reset action of the second elastic element 3422, the first connecting post 3423 will move closer to the positioning cap 341, and the second connecting post 3424 will insert into the positioning groove 3411. The second elastic element 3422 always abuts against the first connecting post 3423, preventing the second connecting post 3424 from disengaging from the positioning groove 3411. In this embodiment, the first connecting post 3423 and the second connecting post 3424 can be fixedly connected by bolts or by adhesive; no specific limitation is made here.

[0061] The first connecting post 3423 is provided with a guide hole, the diameter of which is larger than the diameter of the guide post 3421. The guide hole is assembled with the guide post 3421 to realize the movable connection between the first connecting post 3423 and the guide post 3421, so that it can move along the guide post 3421.

[0062] The second elastic element 3422 is preferably a spring. The spring is sleeved on the guide post 3421 and abuts against the side wall of the mounting groove 313 and the first connecting post 3423. When the second elastic element 3422 is reset, the guide post 3421 can play a certain guiding role, so that the second connecting post 3424 can be inserted into the positioning groove 3411 more accurately.

[0063] Specifically, when a tobacco farmer wears the counter 1, he can first move the first connecting post 3423 away from the positioning cap 341, then insert his wrist between the strap 32 and the fixing member 31. After ensuring that the strap 32 fits against his wrist, he releases the first connecting post 3423, so that the second connecting post 3424 is inserted into the positioning groove 3411 opposite to it, thereby locking the strap 32.

[0064] Preferably, the cross-sectional shape of the second connecting post 3424 is consistent with the shape of the positioning groove 3411, so as to avoid the situation that the winding shaft 3321 will rotate slightly after the second connecting post 3424 is inserted into the positioning groove 3411, and further improve the rationality of the design of the wearing mechanism 3.

[0065] In this embodiment, the fixing member 31 has a semi-circular cross-sectional shape. The retrieving member 33 is placed on one side of the opening of the fixing member 31 and connected to one end of the strap 32. The other end of the strap 32 is connected to the other side of the opening of the fixing member 31. In this way, the shape of the fixing member 31 is more compatible with the shape of the tobacco farmer's wrist, and the strap 32 can fit snugly against the tobacco farmer's wrist, so that the tobacco farmer can wear the field tobacco plant counting device more comfortably.

[0066] In this embodiment, the working process of the field tobacco plant count recording device is as follows: When it is necessary to measure the number of tobacco plants in the field and simultaneously record their growth status, the counter 1 is snapped into place with the connecting seat 21. Then, the tobacco farmer inserts the ground nail post 22 into the field, the movable rod 23 moves towards the counter 1, and the contact plate 232 presses the counting button 11 once. The counter 1 completes one count. As the tobacco farmer pulls out the ground nail post 22, the movable rod 23 and the counting button 11 reset under the action of the first elastic element 233, allowing the counter 1 to perform the next count. After the ground nail post 22 is inserted in front of the corresponding tobacco plant, the farmer's hands are released, enabling the recording of the growth status of the currently counted tobacco plant.

[0067] When the tobacco farmer only needs to record the number of tobacco plants, the wearing mechanism 3 is connected to the counter 1. The insert 342 is operated to move the first connecting post 3423 away from the positioning cap 341, and then the second connecting post 3424 away from the positioning groove 3411. Then, the strap 32 is pulled, and the wrist is inserted between the strap 32 and the fixing member 31. The strap 32 is released, and under the action of the spiral spring 333, the winding shaft 3321 rotates in the opposite direction, and the strap 32 retracts. At this time, the strap 32 and the fixing member 31 are close to the tobacco farmer's wrist. Then the tobacco farmer can loosen the first connecting post 3423. Under the action of the second elastic member 3422, the second connecting post 3424 is inserted into the positioning groove 3411 opposite to it, locking the strap 32. The counter 1 is then worn on the wrist, avoiding the problem of inaccurate tobacco plant count due to arm pain caused by holding the counter 1.
