Description

Technical Field

[0001] The utility model relates to the technical field of bactericide sampling, in particular to a rapid sampling device for bactericide detection. Background Art

[0002] Fungal damage, also known as fungal diseases, is an infectious disease of plants that can be transmitted to other plants and has an infection process. The pathogens are generally parasitic fungi. There are many types of fungal diseases. They not only cause damage in the field but also, due to their latent infection, harm fruit. This can reduce yields and devalue the fruit, resulting in significant losses and seriously affecting fruit production safety. Therefore, fungicides are needed, and fungicides are available in liquid and powder forms.

[0003] When sampling powder fungicides, people mostly rely on basic tools such as spoons and scrapers. During the operation, they need to manually scoop samples from the inside of the fungicide storage container (such as a barrel or tank). This method has obvious defects: on the one hand, the sampling depth is difficult to accurately control, which can easily lead to uneven mixing of samples at different depths. Especially for powder fungicides, the upper and bottom layers of powder may be stratified due to differences in storage time and ambient humidity, which directly affects the representativeness of the test data; on the other hand, powder dust is easily generated during manual operation, which not only causes sample loss, but also poses a threat to the health of the operator. At the same time, external impurities can easily fall into the sample, causing sample contamination.

[0004] Therefore, it is necessary to provide a new rapid sampling device for fungicide detection to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a rapid sampling device for fungicide detection.

[0006] The utility model provides a rapid sampling device for bactericide detection, comprising an operating cylinder, wherein the bottom of the operating cylinder is provided with an internal threaded opening, and a collecting pipe connected by a thread is installed on the internal threaded opening;

[0007] The operating cylinder body is provided with annular grooves distributed in an annular manner, and the operating cylinder body is provided with a plurality of annular feeding ports distributed in an annular manner on the side close to the internal thread opening;

[0008] A negative pressure component is provided in the operating cylinder, and the negative pressure component includes a piston column. The piston column is slidably installed in the operating cylinder, and a coaxially arranged pull rod is fixedly installed on the end of the piston column away from the internal threaded opening. The pull rod extends out of the operating cylinder and is fixedly installed with a handle. A spring A is sleeved on the pull rod.

[0009] Preferably, one end of the spring A is fixedly connected to the end of the piston column away from the internal threaded opening, and the other end of the spring A is fixedly connected to the inner cylinder wall of the operating cylinder.

[0010] Preferably, a conical bucket is fixedly installed in the operating cylinder, and the conical bucket is located between the internal threaded opening and the feed port, and the end of the piston column away from the pull rod is provided with a downward convex cone that matches the conical bucket.

[0011] Preferably, the operating cylinder is equipped with an anti-leakage component for sealing the feed port, and the anti-leakage component includes a sealing tube, which is sleeved in an annular groove opened in the operating cylinder and is slidably connected to the annular groove, and the end of the sealing tube facing away from the internal threaded port is equipped with a rotating ring for rotational connection, and the rotating ring is fixedly equipped with a coaxially arranged spring B and an elastic telescopic sleeve distributed inside and outside, and the other ends of the spring B and the elastic telescopic sleeve are fixedly connected to the side groove wall of the annular groove.

[0012] Preferably, an external threaded portion is provided on a side of the annular groove away from the internal threaded opening, and an internal threaded portion matching the external threaded portion is provided on the inner tube wall of the sealing tube close to the rotating ring.

[0014] Compared with related technologies, the rapid sampling device for fungicide detection provided by the present invention has the following beneficial effects:

[0015] The utility model pulls up the handle to make the piston column slide up and no longer block the feed port, so the feed port is exposed, so that the powdered fungicide outside the feed port can quickly slide into the operating cylinder and finally fall into the collecting pipe, and when the piston column slides up along the operating cylinder, negative pressure is formed at the feed port, so that the operating cylinder can better collect the powdered fungicide, and then the piston column is reset to block the conical bucket, which greatly reduces the risk of sample leakage from the feed port after sampling is completed, thereby ensuring the integrity of the sample. At the same time, when the sampling device is transferred, the powdered fungicide will not be blown away or the sample will be lost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0025] The specific implementation of the utility model is described in detail below in combination with specific examples.

[0026] Please refer to Figures 1 to 7 The utility model embodiment provides a kind of quick sampling device for bactericide detection, and the quick sampling device for bactericide detection includes operation cylinder 1, material collecting pipe 2, negative pressure component 3 and anti-leak component 4.

[0027] In the embodiment of the utility model, please refer to Figures 1 to 7 The bottom of operation cylinder 1 is provided with internal threaded port 1a, and the threaded connecting material collecting pipe 2 is installed on internal threaded port 1a, specifically, the threaded joint 21 that is mutually matched with internal threaded port 1a is fixedly installed on material collecting pipe 2, and the bottom of material collecting pipe 2 is conical seal structure;

[0028] The barrel body of the operation barrel 1 is provided with annular grooves 1b distributed in a ring shape, and a plurality of feeding ports 1c distributed in a ring shape are arranged on the barrel body of the operation barrel 1 close to the inner threaded port 1a, and the operation barrel 1 is provided with a negative pressure component 3, the negative pressure component 3 comprises a piston column 31, the piston column 31 is slidingly installed in the operation barrel 1, and a pull rod 32 coaxially arranged is fixedly installed at one end of the piston column 31 away from the inner threaded port 1a, the pull rod 32 extends out of the operation barrel 1 and is fixedly installed with a handle 33, a spring A 34 is sleeved on the pull rod 32, one end of the spring A 34 is fixedly connected with the one end of the piston column 31 away from the inner threaded port 1a, and the other end of the spring A 34 is fixedly connected with the inner barrel wall of the operation barrel 1;

[0029] The operation barrel 1 is fixedly installed with a conical hopper 11, and the conical hopper 11 is located between the inner threaded port 1a and the feeding port 1c, and the one end of the piston column 31 away from the pull rod 32 is provided with a lower convex cone matched with the conical hopper 11, so that the lower convex cone at the bottom of the piston column 31 is inserted into the conical hopper 11 under the action of the spring A 34, thereby sealing the inner threaded port 1a, and at the same time, the column body of the piston column 31 also blocks the feeding port 1c.

[0030] It should be noted that when sampling the powder type fungicide, the collecting pipe 2 is inserted into the powder type fungicide to a predetermined sampling depth by using the operation barrel 1, and when taking the medicine, the handle 33 is pulled up to make the piston column 31 slide upward and not block the feeding port 1c, so that the feeding port 1c is exposed, and therefore the powder type fungicide around the feeding port 1c can quickly slide into the operation barrel 1 and finally fall into the collecting pipe 2, and at the same time, the piston column 31 slides upward along the operation barrel 1, and the negative pressure is formed at the feeding port 1c, so that the operation barrel 1 can better collect the powder type fungicide;

[0031] After the collection is completed, the pull rod 32 is slowly lowered, which reduces the flocculation of the powder type fungicide in the collecting pipe 2 during the process that the piston column 31 blocks the conical hopper 11, and after the piston column 31 is reset to block the conical hopper 11, the risk of sample leakage from the feeding port 1c after sampling is completed is greatly reduced, and the integrity of the sample is ensured, and at the same time, the sampling device does not cause the powder type fungicide to float or the sample to be lost during transfer, and when the sample in the collecting pipe 2 needs to be placed into a sample bottle, the powder type fungicide can be poured into the sample bottle by rotating the lower collecting pipe 2.

[0032] In the embodiment, since the bottom of the collecting pipe 2 is in a conical sealing structure, the collecting pipe 2 can be easily inserted into a storage container of the powder type fungicide.

[0033] In the embodiment of the utility model, in order to further reduce the powder type fungicide from the feeding port 1c when the piston column 31 is reset to block the conical hopper 11, a leakage prevention component 4 is additionally arranged on the basis of the above embodiment, wherein the leakage prevention component 4 can also not be installed according to the needs of the staff, please refer toFigures 1 to 7 The operation cylinder 1 is provided with a leak-proof component 4 for plugging the feeding port 1c, and the leak-proof component 4 comprises a plugging pipe 41 sleeved in the annular groove 1b of the operation cylinder 1 and in sliding connection with the annular groove 1b, the plugging pipe 41 is provided at one end away from the inner threaded port 1a with a rotating ring 42 in rotating connection, and the rotating ring 42 is fixedly provided with a spring B 43 and an elastic telescopic sleeve 44 coaxially arranged and distributed inside and outside, the other ends of the spring B 43 and the elastic telescopic sleeve 44 are fixedly connected with the side groove wall of the annular groove 1b, and the side of the annular groove 1b away from the inner threaded port 1a is provided with an external threaded part 12, and the inner wall of the plugging pipe 41 close to the rotating ring 42 is provided with an internal threaded part 411 matched with the external threaded part 12.

[0034] It should be noted that: due to the elastic force of the spring B 43, the plugging pipe 41 abuts against the lower groove wall of the annular groove 1b, so that the plugging pipe 41 performs secondary plugging on the feeding port 1c, when the collecting pipe 2 is inserted into the powder type fungicide to a predetermined sampling depth, the plugging pipe 41 is lifted to compress the spring B 43 and the elastic telescopic sleeve 44 synchronously, until the internal threaded part 411 abuts against the external threaded part 12, the plugging pipe 41 is rotated to be locked, at this time, the feeding port 1c is exposed, then the handle 33 is pulled upward to make the piston column 31 slide upward and the feeding port 1c is no longer plugged, and the sampling can be performed;

[0035] When the sampling is completed, the plugging pipe 41 is reversed to be unlocked, then the plugging pipe 41 is quickly plugged under the elastic force of the spring B 43 (the plugging pipe 41 can also be reset by manually pressing the plugging pipe 41), then the staff slowly releases the pull rod 32, since the feeding port 1c is plugged by the plugging pipe 41, the powder type fungicide is reduced in the amount of discharging from the feeding port 1c when the piston column 31 is reset to plug the conical hopper 11.

[0036] It should be noted that: in order to avoid the phenomenon that the powder enters the gap between the plugging pipe 41 and the operation cylinder 1, two high-temperature-resistant and wear-resistant rubber sealing rings can be additionally arranged at the matching position between the inner wall of the plugging pipe 41 and the outer wall of the annular groove 1b, the sealing ring adopts a "V"-shaped structure, and is tightly attached to the outer wall of the annular groove 1b by elastic deformation, thereby forming a first dust barrier, and a dust-proof lip is arranged on the inner wall of one end of the plugging pipe 41 close to the inner threaded port 1a, the dust-proof lip is made of flexible polyurethane material, and the inclined direction thereof faces the feeding port 1c, so that the dust-proof lip can effectively block the powder from moving to the matching gap, thereby forming a second dust barrier.

[0037] In addition, when the internal threaded part 411 of the plugging pipe 41 is locked with the external threaded part 12, the plugging pipe 41 is rotated for one to two circles to be locked, thereby facilitating the subsequent staff to unlock with one hand.

[0038] In the embodiment, the spring B43 and the elastic telescopic sleeve 44 are connected with the plugging pipe 41 through the rotating ring 42, so that the plugging pipe 41 is not easy to cause the spring B43 and the elastic telescopic sleeve 44 to be twisted after being rotated.

[0039] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is made by using the content of the present application specification and drawings, is also included in the patent protection scope of the present application.
