[0002] With the development of animal husbandry technology, the production mode of animal husbandry has undergone a positive transformation, and as a whole, it is tending towards large-scale, intensive, ecological, specialized, automated, and intelligent. This transformation of the production mode has promoted the overall modern production mode of animal husbandry to be more efficient. Sampling tubes play a crucial role in animal husbandry production. Sampling tubes are used to collect samples from livestock bodies or production environments for disease detection, health monitoring, nutritional analysis, and production performance evaluation. However, there are still deficiencies in the automated production of sampling tubes at present, especially in the blanking of sampling tubes.

[0003] The sampling tube usually has a long tubular structure with an end opening and a hollow interior, and a head is provided inside one end to seal the tube body.

[0004] The existing sampling tube blanking method usually uses a blanking hopper for blanking. The existing blanking hopper is composed of four vertical plates in the front, back, left, and right and a bottom plate, forming a hopper with an open top. The bottom plate is usually inclined, with the rear end higher than the front end. There is a strip-shaped discharge port starting from the lower end of the front vertical plate, and the strip-shaped discharge port is horizontally arranged. During blanking, multiple sampling tubes are placed into the blanking hopper from the open top of the blanking hopper, and then the sampling tubes roll along the bottom plate to the discharge port, so that the sampling tubes continuously go out from the discharge port to complete blanking.

[0005] However, when a large number of sampling tubes are placed in the blanking hopper, the sampling tubes will be concentrated and piled up at the discharge port, resulting in the blockage of the discharge port and thus unable to blank.

[0006] Therefore, it is particularly necessary to provide a new pipe blanking hopper to prevent blockage during the blanking of the blanking hopper. Summary of the Utility Model

[0040] Such as Figures 1 to 6As shown in the figure, the utility model discloses a pipe blanking hopper, which can be used for blanking pipes such as sampling pipes. The blanking hopper includes a left vertical plate 1, a right vertical plate 3, a rear vertical plate 2, a bottom plate 5 and a front baffle;

[0041] The left vertical plate 1, the right vertical plate 3 and the rear vertical plate 2 are vertically arranged; the rear end of the left vertical plate 1 is connected to the left end of the rear vertical plate 2, and the rear end of the right vertical plate 3 is connected to the right end of the rear vertical plate 2; the bottom plate 5 is located between the left vertical plate 1 and the right vertical plate 3, and the bottom plate 5 is inclined so that its rear end is higher than the front end; the left end of the bottom plate 5 is connected to the left vertical plate 1, the right end of the bottom plate 5 is connected to the right vertical plate 3, and the rear end of the bottom plate 5 is connected to the rear vertical plate 2;

[0042] The front baffle is arranged at the front end of the bottom plate 5, and the front baffle includes a plurality of mutually parallel cross bars 7 and a plurality of mutually parallel vertical plates 6; the vertical plates 6 are fixedly arranged on the cross bars 7, the left end of the cross bar 7 is connected to the left vertical plate 1, and the right end of the cross bar 7 is connected to the right vertical plate 3; the bottom plate 5 is located below the vertical plate 6, and the gap between the bottom plate 5 and the lower end of the vertical plate 6 forms a discharge channel;

[0043] A material pushing wheel is arranged between the vertical plates 6, and the material pushing wheel is close to the upper surface of the bottom plate 5; the material pushing wheel is sleeved on the material pushing wheel drive shaft, the left end of the material pushing wheel drive shaft is rotatably connected to the left vertical plate 1, and the right end of the material pushing wheel drive shaft is rotatably connected to the right vertical plate 3; one end of the material pushing wheel drive shaft is connected to the material pushing wheel drive device, and the material pushing wheel drive device can be a material pushing wheel drive motor, and the material pushing wheel drive motor can be fixedly arranged on the left vertical plate 1 or the right vertical plate 3.

[0044] In the utility model, the front vertical plate of the existing blanking hopper is replaced with a front baffle. Since there is a gap between the front baffles, it is convenient to install the material pushing wheel. By using the material pushing wheel to push the pipes, the blockage during blanking can be prevented.

[0045] Furthermore, the material pushing wheel is a gear or a ratchet wheel.

[0046] During operation, the rotation direction of the material pushing wheel is opposite to the blanking direction of the sampling pipe. By rotating the material pushing wheel, the pipes inside the blanking hopper are continuously pushed upward, preventing material blockage. At the same time, the discharge speed can also be controlled.

[0047] Furthermore, the lower end of the vertical plate 6 is bent into an arc shape, so that the discharge channel formed by the bottom plate 5 and the lower end of the vertical plate 6 gradually decreases from the rear end to the front end of the bottom plate 5 until the gap between the lower end of the vertical plate 6 and the bottom plate 5 only allows one pipe to pass through.

[0048] Such as Figure 1 、 3As shown, the lower end of the vertical plate 6 is bent into an arc shape, which can gradually concentrate the pipe materials to the outlet of the discharge channel, avoiding the blockage caused by all the large pipe materials concentrating at the outlet of the discharge channel.

[0049] Furthermore, the material pushing wheel is located at the inlet of the discharge channel, that is, at the bent part of the lower end of the vertical plate 6. And the driving shaft of the material pushing wheel is located on the front side of the front baffle, that is, outside the hopper, so as to avoid the influence of the driving shaft of the material pushing wheel on the inside of the hopper.

[0050] Furthermore, a guide plate 4 is arranged on the back surface of the vertical plate 6. The guide plate 4 is bent into an arc shape. The upper end of the guide plate 4 is detachably connected to the vertical plate 6, and the lower end of the guide plate 4 is connected to the lower end of the vertical plate 6, forming a continuously bent arc shape.

[0051] The guide plate 4 is bent into an arc shape, which can gradually reduce the gap between the guide plate 4, the rear vertical plate 2 and the bottom plate 5, and can gradually concentrate the pipe materials to the outlet of the discharge channel. The upper end of the guide plate 4 is detachably connected to the vertical plate 6, which can facilitate the replacement of the guide plate 4 with different radian according to the actual situation, and then adjust the gap between the guide plate 4, the rear vertical plate 2 and the bottom plate 5. Furthermore, it is more conducive to gradually concentrating the pipe materials to the outlet of the discharge channel.

[0052] Furthermore, the outlet of the discharge channel is connected to the blanking mechanism; the blanking mechanism includes a scraping plate 12, a baffle mounting member 11, a baffle 10 and a receiving tray 13; the scraping plate 12 and the baffle mounting member 11 are arranged vertically, the baffle mounting member 11 is located in front of the scraping plate 12, and the gap between the scraping plate 12 and the baffle mounting member 11 forms a blanking channel. The inlet of the blanking channel is located at the upper end, and the outlet of the blanking channel is located at the lower end. The inlet of the blanking channel is communicated with the outlet of the discharge channel; the lower end of the scraping plate 12 is lower than the lower end of the baffle mounting member 11; the baffle 10 is arc-shaped, the upper end of the baffle 10 is rotatably arranged on the front surface of the baffle mounting member 11, and the lower end can bypass the lower end of the baffle mounting member 11 to block the outlet of the blanking channel; the upper end of the baffle 10 is connected to the baffle driving mechanism, and the baffle driving mechanism is used to drive the baffle 10 to rotate; the receiving tray 13 is arranged horizontally below the blanking channel; the receiving tray 13 is connected to the receiving tray driving mechanism, and the receiving tray driving mechanism is used to drive the receiving tray 13 to move back and forth.

[0053] When the pipe material enters the blanking channel from the upper end of the blanking channel, when the baffle driving mechanism drives the baffle 10 to rotate forward, that is, counterclockwise, to open the outlet of the blanking channel, the receiving tray driving mechanism drives the receiving tray 13 to move forward, and then the pipe material coming out of the blanking channel can be caught; when the baffle driving mechanism drives the baffle 10 to rotate backward, that is, clockwise, to close the outlet of the blanking channel, the receiving tray driving mechanism drives the receiving tray 13 to move backward, and the lower end of the scraping plate 12 scrapes the pipe material from the front end of the receiving tray 13.

[0054] Due to the existence of the blanking mechanism, it is possible to blank the pipes one by one. In the above structure, the baffle plate 10 blocks the outlet of the blanking channel to prevent the continuous falling of the pipes, while the cooperation of the receiving tray 13 and the scraping plate 12 ensures the blanking of the pipes one by one. When the receiving tray 13 catches multiple pipes, the pipes will be laid flat on the receiving tray 13. Since the pipes are laid on the receiving tray 13, when the receiving tray 13 moves backward, the lower end of the scraping plate 12 will touch the pipes and push the pipes forward to move to the front end of the receiving tray 13, so that the pipes close to the front end of the receiving tray 13 will fall out first. If the receiving tray 13 continues to move backward, the pipes arranged behind will also fall out from the front end of the receiving tray 13 in turn, thus completing the blanking of the pipes one by one.

[0055] In actual use, the opening and closing time of the outlet of the blanking channel can be controlled according to the blanking speed of the pipes in the blanking channel to ensure that there is only one pipe on the receiving tray 13.

[0056] In the present utility model, the lower end of the scraping plate 12 is lower than the lower end of the baffle plate mounting member 11; this is to ensure that the lower end of the scraping plate 12 can touch the pipes. The lower end of the baffle plate mounting member 11 is higher to ensure that there is enough space at the lower end of the baffle plate mounting member 11 for the lower end of the baffle plate 10 to pass through, which is convenient for the lower end of the baffle plate 10 to block the outlet of the blanking channel. At the same time, it can also prevent the baffle plate 10 from scraping the pipes off the receiving tray 13 when it rotates forward.

[0057] As Figures 3 to 6 shown, the scraping plate 12 is fixedly arranged at the front ends of the left vertical plate 1 and the right vertical plate 3, below the bottom plate 5. The left end and the right end of the baffle plate mounting member 11 are respectively connected to the left vertical plate 1 and the right vertical plate 3 through the connecting rods 8, so that the baffle plate mounting member 11 is located in front of the scraping plate 12; a sliding seat 9 is arranged below the receiving tray 13, and the receiving tray 13 is arranged on the sliding seat 9 through a guide rail.

[0058] The receiving tray driving mechanism can be a cylinder horizontally arranged on the sliding seat 9, and the piston rod of the cylinder is connected to the bottom of the receiving tray 13, and the cylinder is used to drive the receiving tray 13 to move back and forth.

[0059] The baffle plate mounting member 11 is a vertically arranged flat plate or a frame structure composed of a plurality of cross bars 7 and vertical plates 6, Figure 5 In, the baffle plate mounting member 11 is a frame structure. A baffle plate rotating shaft 14 is arranged on the front surface of the baffle plate mounting member 11, the baffle plate rotating shaft 14 is horizontally arranged and rotatably arranged on the front surface of the baffle plate mounting member 11; the upper end of the baffle plate 10 is fixedly arranged on the baffle plate rotating shaft 14.

[0060] The baffle plate driving mechanism can be a baffle plate driving motor arranged on the baffle plate mounting member 11, and the baffle plate driving motor is connected to the baffle plate rotating shaft 14.

[0061] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
