DETAILED DESCRIPTION

[0026] In order to make the technical field of the present application or the prior art more clearly, the drawings needed in the embodiments will be briefly introduced below, and obviously, the drawings described below are only some embodiments of the present application, and other drawings can be obtained by those skilled in the art according to these drawings. Figs. 1-3 The present application will be further described in detail.

[0027] The embodiment of the present application provides a sample specimen collection device, which comprises a pole frame 1, the pole frame 1 is provided with a cutting assembly 2 and a collection barrel 3, the collection barrel 3 is located directly below the cutting assembly 2, and the sample specimen collection device further comprises:

[0028] A buffer bag 4 is arranged in the collection barrel 3, and the buffer bag 4 is used for buffering the impact when the sample falls;

[0029] The collection barrel 3 is arranged below the buffer bag 4, the collection barrel 3 comprises a guide 31 and a rotatable collection part 32, the guide 31 is located directly below the buffer bag 4, the collection part 32 comprises a plurality of collection frames 321, the collection part 32 rotates, different collection frames 321 are adjusted to face the guide 31 directly, and the guide 31 guides the sample into the collection frame 321 of the collection part 32.

[0030] Specifically, in the embodiment, the cutting assembly 2 can be an electrically controlled shear, wherein the cutting assembly 2 and the collection barrel 3 are located on the same side of the pole frame 1, and a remote switch is arranged on the other side of the pole frame 1, the remote switch controls the electrically controlled shear to perform a shearing action. It should be noted that in the embodiment, the sample to be collected is a fruit of a plant; when the existing sample collection is performed, the worker holds up the pole frame 1, so that the cutting assembly 2 is opposite the connection between the sample and the tree, at this time, the collection barrel 3 is located directly below the sample, then the worker remotely controls the electrically controlled shear to cut the sample on the book, the cut sample falls into the collection barrel 3 under the action of gravity, and the collection of the sample is completed.

[0031] However, when the existing sample is collected, in order to ensure the accuracy of subsequent research data, multiple samples are often collected, if the above sample collection method is used, when multiple samples are collected, the subsequently collected sample will directly hit the previously collected sample under the action of gravity, the sample is impacted, and the surface of the sample is easily damaged, which affects the accuracy of the subsequent research data. Obviously, the worker can also collect the sample after collecting one sample, and this collection method greatly increases the workload of the worker.

[0032] In order to solve the above problems, a buffer bag 4 is arranged in the collection barrel 3, the buffer bag 4 buffers the impact of the sample when falling, and the collection barrel 3 is in a round barrel state, the collection part 32 is coaxially arranged with the collection barrel 3, wherein the guide 31 can be a slope, when the sample falls on the slope, the slope guides the sample, and the guided sample enters the collection frame 321, in the embodiment, the rotation of the collection frame 321 can be connected with a driving motor on the collection frame 321, and the driving motor is used to drive the collection frame 321 to rotate in the collection barrel 3.

[0033] Thus, in the embodiment, the collection steps of the sample are as follows:

[0034] Firstly, the worker uses the cutting assembly 2 to cut the connection between the sample and the tree, the sample falls on the surface of the buffer bag 4 under the action of gravity, the sample rolls on the guide 31 under the buffering action of the buffer bag 4, and the sample rolls into an empty collection frame 321 under the guidance of the guide 31, and the collection of the sample is completed.

[0035] Subsequently, the driving motor drives the collection frame 321 to rotate around the axis in the collection barrel 3, so that another empty collection frame 321 is opposite the guide 31, and waits for the next round of sampling, at this time, the two rounds of samples are respectively in the two collection frames 321, and each sample is separately placed, avoiding the situation that multiple samples are collected in the collection barrel 3 at one time, and the samples are directly collided with each other, which causes the sample to be damaged and affects the sampling quality.

[0036] Preferably, the buffer bag 4 is provided with a funnel-shaped buffer channel 41, wherein, by providing the funnel-shaped buffer channel 41, as long as the sample falls on the surface of the buffer bag 4, the buffer bag 4 can guide the sample through the buffer channel 41 to enter the guide 31, so as to ensure that the collected sample can be collected.

[0037] Preferably, the guide 31 comprises a guide inclined plate 311, the inclined surface of the guide inclined plate 311 is inclined downward, the guide inclined plate 311 is connected with the collection barrel 3 through a buffer spring 312, and the surfaces of the collection frame 321 and the guide 31 are both provided with rubber sleeves.

[0038] Specifically, by providing the rubber sleeves on the surfaces of the guide inclined plate 311 and the collection frame 321, the sample can be protected, so as to avoid damage caused by excessive impact when the sample contacts the guide inclined plate 311 or the collection frame 321. In addition, the buffer spring 312 is connected between the guide inclined plate 311 and the collection barrel 3, when the sample falls on the guide inclined plate 311, the buffer spring 312 further buffers the impact force of the sample, and the contact mode between the sample and the guide inclined plate 311 is changed from hard contact to flexible contact, so as to further protect the sample and avoid damage caused by sample collection.

[0039] Preferably, the buffer bag 4 and the collection barrel 3 are detachably connected.

[0040] Specifically, the buffer bag 4 and the collection barrel 3 are directly connected through clamping, when the sample in the collection barrel 3 needs to be taken out, the staff directly detaches the buffer bag 4 from the collection barrel 3, and the sample in the collection barrel 3 is collected.

[0041] Obviously, after the collection part 32 rotates one circle, the collection frame 321 containing the sample will face the guide 31 again, and if the sample collection is performed again, the sample along the guide 31 is easy to collide with the sample in the collection frame 321, which affects the quality of the sample in the collection frame 321.

[0042] In order to solve the above problems, a plurality of collecting boxes 321 on the collecting part 32 are sequentially arranged along the circumference of the guide 31, the surface of the collecting box 321 is provided with a communication gap 322, the communication gap 322 is used for the sample to enter into the collecting box 321, the collecting part 32 further comprises a collecting ring frame 323 and a driving module 324, the collecting ring frame 323 is provided with a plurality of collecting gaps 325, the collecting box 321 is arranged in the collecting gap 325, the driving module 324 drives the collecting ring frame 323 to rotate with the collecting box 321, the collecting gap 325 is provided with a rectangular spiral groove 326, the surface of the collecting box 321 is provided with a sliding block 327, the sliding block 327 is inserted into the rectangular spiral groove 326, the collecting box 321 and the collecting ring frame 323 are connected through an elastic element 328, and the driving module 324 drives the collecting ring frame 323 to rotate intermittently.

[0043] Specifically, the driving module 324 can select a servo motor, the intermittent rotation of the servo motor is a prior art, and the principle will not be described herein. The servo motor is not connected to the center position of the driving collecting ring frame 323 in order to avoid the buffer spring 312 connected between the guide inclined plate 311 and the collecting barrel 3. The servo motor is connected to the collecting ring frame 323 through a transmission part. The transmission part can select two gears. One gear is coaxially arranged with the collecting ring frame 323, and the other gear is connected to the output end of the servo motor. The two gears are meshed with each other. In this embodiment, the elastic element 328 can be selected as an elastic rope.

[0044] In this embodiment, the collecting step of the sample is as follows.

[0045] Firstly, the staff cuts off the connection between the sample and the tree by using the cutting assembly 2. The sample falls to the surface of the buffer bag 4 under the action of gravity. Under the buffer guide of the buffer channel 41 on the buffer bag 4, the sample rolls to the guide 31 and rolls into an idle collecting box 321 under the guide of the guide 31, and the collecting of the sample is completed.

[0046] Subsequently, when the sample falls into the collecting box 321, the weight of the collecting box 321 increases, the collecting box 321 moves downward along the vertical direction in the collecting gap 325, the elastic rope is stretched to accumulate elastic potential energy (when the sample is taken out later, the elastic rope releases the accumulated elastic potential energy to pull the collecting box 321 back to the original position), the rectangular spiral groove 326 is arranged on the inner wall of the collecting gap 325, the sliding block 327 on the collecting box 321 slides along the rectangular spiral groove 326 when the collecting box 321 moves downward, so that the collecting box 321 rotates in the collecting gap 325, and the communication gap 322 on the collecting box 321 no longer faces the guide 31.

[0047] Afterwards, the driving module 324 drives the collection ring frame 323 to rotate in the collection barrel 3, and switches another empty collection frame 321 to face the guide 31, waiting for the next round of sampling.

[0048] Obviously, since the collection notch 325 of the collection frame 321 is changed, even if the collection part 32 rotates one round, the collection frame 321 containing the sample will face the guide 31 again, but at this time, the collection notch 325 has been deflected, and the sample in the guide 31 cannot collide with the sample in the collection frame 321, resulting in the sample damage.

[0049] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for those skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the present application.
