[0021] Example 1

[0022] REFERENCE Figure 1The aerobic compost pretreatment sampling device comprises a spiral sampling shaft 1, a spiral sleeve 2 and a hand wheel 3. The spiral sleeve 2 is fixedly connected with the pretreatment device. In this embodiment, the open end of the spiral sleeve 2 is welded with the shell 10 of the pretreatment device, so that the sampling device does not need to be disassembled and assembled every time. In other embodiments, the spiral sleeve 2 can be detachably connected with the pretreatment device through a fixing seat by means of a screw, like the prior art.

[0023] The spiral sleeve 2 is open at one end and closed at the other end. The spiral sampling shaft 1 is arranged inside the spiral sleeve 2 and extends from the closed end of the spiral sleeve 2. The inner end of the spiral sampling shaft 1 is provided with spiral blades. The hand wheel 3 is connected with the outer end of the spiral sampling shaft 1. The connection mode of the hand wheel 3 with the spiral sampling shaft 1 is not limited, for example, welding or connecting through a connecting key, as long as the hand wheel 3 can drive the spiral sampling shaft 1 to rotate.

[0024] The spiral sampling shaft 1 is slidably connected with the closed end of the spiral sleeve 2, that is, the spiral sampling shaft 1 can not only rotate but also move axially to change the insertion depth. In this embodiment, the end of the spiral sampling shaft 1 close to the hand wheel 3 is provided with a scale mark along the axial direction, which is used to indicate the insertion depth of the spiral sampling shaft 1. According to the scale mark, the operator can intuitively know the insertion depth of the spiral sampling shaft 1. Meanwhile, the spiral sampling shaft 1 is provided with a position-adjustable positioning component. After the insertion depth is determined, the positioning component is used to limit the insertion depth. When sampling, a certain pressure is applied to make the positioning component abut against the outside of the closed end of the spiral sleeve 2, and the hand wheel 3 is rotated to drive the spiral sampling shaft 1 to rotate, so that the material enters the inside of the spiral sleeve 2.

[0025] As an option, the positioning component in this embodiment comprises a sleeve 4 and a locking screw 5. The sleeve 4 is slidably sleeved on the spiral sampling shaft 1, and the locking screw 5 is connected to the side wall of the sleeve 4. In actual application, the sleeve 4 can be slid to the corresponding scale mark according to the insertion depth, and the locking screw 5 is tightened to abut against the spiral sampling shaft 1 to fix the sleeve 4, and then the spiral sampling shaft 1 is pushed to make the sleeve 4 abut against the outside of the closed end of the spiral sleeve 2. Alternatively, the spiral sampling shaft 1 can be pushed to a certain depth first, and then the position of the sleeve 4 is fixed.

[0026] The spiral sleeve 2 is provided with a discharge port 201 on one side. The spiral sleeve 2 is detachably connected with a sealing element 8 used to close the discharge port 201. When sampling, the sealing element 8 is disassembled in advance to expose the discharge port 201. When the hand wheel 3 is rotated for sampling, the material can flow out of the discharge port 201. After sampling is completed, the sealing element 8 is connected and sealed to close the discharge port 201.

[0027] Alternatively, the sealing member 8 in this embodiment is a sleeve and is connected to the outer wall of the screw sleeve 2 by screwing. It is worth mentioning that, in this way, the sealing member 8 does not need to be separated from the screw sleeve 2 when sampling, and only needs to be rotated to move axially relative to the screw sleeve 2 to expose the discharge port 201, which is more convenient to use. In other embodiments, the sealing member 8 can of course also have other structures, for example, a connecting flange is provided at the discharge port 201, and a cover is connected to close the discharge port 201. For example, the sealing member 8 is also a sleeve, and a screw is connected to the side wall of the sleeve to abut against the screw sleeve 2 to achieve position fixing.

[0028] Embodiment 2

[0029] Reference Figure 2 The difference between this embodiment and embodiment 1 is that the specific structure of the positioning component is different. In this embodiment, the positioning component includes a fixing ring 6 and a positioning screw 7. The fixing ring 6 is fixedly arranged on the screw sampling shaft 1, and the positioning screw 7 is connected to the fixing ring 6 by screwing. The end of the positioning screw 7 abuts against the outside of the closed end of the screw sleeve 2. By changing the connection position of the positioning screw 7 and the fixing ring 6, the depth at which the screw sampling shaft 1 can be inserted can be changed. Further, in order to ensure stability, two positioning screws 7 can be symmetrically arranged.

[0030] Embodiment 3

[0031] Reference Figure 3 This embodiment is further optimized on the basis of embodiment 1 (it is easy to understand that in other embodiments, this embodiment can of course be further optimized on the basis of embodiment 2). The open end of the screw sleeve 2 is provided with a plurality of sealing springs 9 in the circumferential direction, which are used to close the open end of the screw sleeve 2 to prevent material from entering the screw sleeve 2 when sampling is not needed.

[0032] Alternatively, in this embodiment, one end of the sealing spring 9 is connected to the screw sleeve 2 by a torsion spring (not shown in the figure). Under the elastic action of the torsion spring, the end of each sealing spring 9 away from the screw sleeve 2 has a tendency to move towards the center of the screw sleeve 2. After the end of the screw sampling shaft 1 provided with the screw blade is retracted into the screw sleeve 2, each sealing spring 9 closes the open end of the screw sleeve 2. When sampling is needed, the screw sampling shaft 1 is pushed, each sealing spring 9 is extruded to open outward and the torsion spring is charged.

[0033] In other embodiments, the sealing spring 9 can also have other structures, for example, the sealing spring 9 is elastic (for example, selected from spring steel), one end of the sealing spring 9 is connected with the spiral sleeve 2 (for example, welded or fastened by a screw), and the spiral sampling shaft 1 is provided with spiral blades. After the end of the spiral sampling shaft 1 is retracted into the spiral sleeve 2, each sealing spring 9 is not subjected to external force and is in a state of closing the open end of the spiral sleeve 2. When sampling is needed, the spiral sampling shaft 1 is pushed to make each sealing spring 9 subjected to force (elastic deformation) and open outward.

[0034] The preferred embodiments of the utility model are merely used for limiting the utility model, and for those skilled in the art, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
