Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a material blowing and collecting mechanism and a sampling tube for a sampling device. Background Art

[0002] In the inspection and quarantine of grain imports at the customs, a relatively large amount of grain cargo is transported to the seaport terminal by bulk sea vessels. Before the cargo is unloaded, the grain on the transport ship at the port needs to be inspected and quarantined, and the surface inspection and sampling are carried out on site. Unloading is allowed only after the monitoring is qualified. After the sampling is completed in the existing sampling equipment, the sample in the sampling tube needs to be unloaded, but it does not have a special unloading structure. Most of them rely on the gravity of the material itself to complete the unloading. This unloading method is not only inefficient but may also leave samples in the sampling tube, greatly affecting the scientific nature of the sampling; most of the current sampling tubes adopt a double-layer structure, and the material slot is opened or closed by rotating the two-layer structure. However, since the inner and outer layers of the structure have a certain gap, some particle samples will be stuck at the material slot during the rotation process, causing it to rotate poorly and damage the equipment in serious cases. Utility Model Content

[0003] The utility model provides a material blowing and collecting mechanism and a sampling tube for a sampling device, aiming to solve the technical problems existing in the prior art.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is:

[0005] A material blowing and collecting mechanism and a sampling tube for a sampling device, comprising a sampling tube and a material blowing and collecting mechanism, wherein the sampling tube comprises an inner tube and an outer sleeve, and a discharge slot is arranged at the bottom of the outer sleeve; the material blowing and collecting mechanism comprises a converging and collecting tube and a DC turbine fan, wherein the converging and collecting tube is installed at the discharge slots of a plurality of outer sleeves, and the DC turbine fan is connected to a position directly opposite to the discharge slot of the outer sleeve.

[0006] Furthermore, a plurality of feed slots are provided on the inner tube, and a group of feed slots that penetrate each other are provided at the lowermost part of the inner tube.

[0007] Furthermore, the outer sleeve is fixedly arranged, and the inner tube can move up and down and rotate in the outer sleeve, and the side surfaces of the discharge slot and the feed slot are blade foot structures with opposite cutting edges.

[0008] Furthermore, the converging and collecting pipe is a multi-way pipe fitting and its outlet is located lower than the feed inlet. The converging and collecting pipe is installed on the outer sleeve through a pipe clamp.

[0009] Furthermore, an air inlet interface is provided on the outer sleeve, and the position of the air inlet interface is opposite to the processing notch.

[0010] Furthermore, the DC turbine blower is connected to a plurality of air inlet interfaces via a hose and a multi-way pipe fitting.

[0011] Furthermore, a cone head is provided at the bottom of the inner tube, and ventilation holes are provided on the cone head along its radial direction.

[0012] Based on the above technical solution, the following technical effects can be produced:

[0013] 1. The utility model provides a sampling device with a material blowing and collecting mechanism and a sampling tube. After the sampling is completed, the inner tube rotates so that the feed slot on the bottom is directly opposite to the discharge slot on the outer sleeve. At the same time, the DC turbine fan is turned on to blow all the samples into the converging collection tube for collection, so that the sampling is more efficient and the sampling quality is improved.

[0014] 2. The utility model provides blade foot structures with opposite cutting edges at the feed slot and the discharge slot of the sampling tube. When the inner tube is rotated and closed, the blade foot structure between the outer sleeve and the inner tube forms a shearing effect to cut off the material stuck between the two, thereby preventing the motor from being damaged due to material jamming during the rotation process, which makes it impossible to complete the sampling.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 5 A material blowing and collecting mechanism and a sampling tube for a sampling device, characterized in that it comprises a sampling tube 1 and a material blowing and collecting mechanism, the sampling tube 1 comprises an inner tube 1.1 and an outer sleeve 1.2, and a discharge slot 1.21 is arranged at the bottom of the outer sleeve 1.2; the material blowing and collecting mechanism comprises a converging and collecting tube 2 and a DC turbine fan 3, the converging and collecting tube 2 is installed at the discharge slots 1.21 of multiple outer sleeves 1.2, and the DC turbine fan 3 is connected to a position directly opposite to the discharge slot 1.21 of the outer sleeve 1.2.

[0026] According to one embodiment of the utility model, a plurality of feed slots 1.11 are provided on the inner tube 1.1, and a group of opposite feed slots 1.11 are provided at the lower part of the inner tube. When unloading samples, the group of opposite feed slots 1.11 are aligned with the discharge slot 1.21 on the outer sleeve 1.2, and also with the air inlet interface 4, thereby ensuring that the material blowing function is effectively realized when the sampling tube discharges materials.

[0027] According to an embodiment of the utility model, the outer sleeve 1.2 is fixedly arranged, the inner tube 1.1 can move up and down and rotate in the outer sleeve 1.2, and the sides of the discharge slot 1.21 and the feed slot 1.11 are blade foot structures with opposite blade edges. When the inner tube is rotated and closed, the blade foot structure between the outer sleeve and the inner tube forms a shearing effect to cut off the material stuck between the two, preventing the motor from being damaged due to material jamming during the rotation process, and failing to complete sampling.

[0028] According to one embodiment of the utility model, the converging and collecting tube 2 is a multi-way pipe fitting and its outlet position is lower than the feed port position. The converging and collecting tube 2 is installed on the outer sleeve 1.2 through a pipe clamp. In this embodiment, the converging and collecting tube 2 is a "Y"-shaped three-way structure, and the two feed ports are combined into one outlet with their own slopes, and the sample bag is tied at the outlet.

[0029] According to an embodiment of the present invention, an air inlet interface 4 is provided on the outer sleeve 1.2, and the position of the air inlet interface 4 is opposite to the processing notch 1.21.

[0030] According to an embodiment of the present utility model, the DC turbine blower 2 is connected to a plurality of air inlet interfaces 4 via a hose 5 and a multi-way pipe fitting.

[0031] According to an embodiment of the utility model, a cone head 1.12 is provided at the bottom of the inner tube 1.1, and ventilation holes are provided on the cone head 1.12 along its radial direction.

[0032] The working principle of the material blowing and collecting mechanism and the sampling tube for the sampling device provided by the utility model is as follows:

[0033] After the inner tube 1.1 is sampled, it is recovered and the feed slot 1.11 at the bottom of the inner tube 1.1 is aligned with the discharge slot 1.21 at the bottom of the outer tube 1.2. The inner tube 1.1 rotates until the two slots are fully opened. During this process, the blade structures on the feed slot 1.11 and the discharge slot 1.21 shear the material stuck between the inner tube 1.1 and the outer tube 1.2. Then the DC turbine fan 3 is turned on to blow the material into the converging collection pipe 2 through the air inlet interface 4 facing the discharge slot 1.21. The material on the upper part of the inner tube 1.1 will fall to the bottom due to gravity and continue to be blown out until the material in the inner tube 1.1 is completely discharged.

[0034] The utility model is described in detail above with reference to the accompanying drawings and embodiments, but the utility model is not limited to the above embodiments, and various changes can be made within the scope of ordinary technicians in the field without departing from the purpose of the utility model.
