[0035] Hereinafter, the technical solutions of the present application will be exemplarily described through some embodiments.

[0036] See Figures 1 to 3 , an embodiment of the present application provides a granular feed conveying and sampling device 100, including a material conveying pipeline 110, a sampling conveying pipeline 120, and a sampling assembly 130.

[0037] The material conveying pipeline 110 refers to a pipeline for conveying granular feed products. A sampling outlet 111 is provided on the side of the material conveying pipeline 110. It can be understood that the sampling outlet 111 is in communication with the inside of the material conveying pipeline 110 and is used as a window for sampling from the material conveying pipeline 110.

[0038] The sampling conveying pipeline 120 refers to a pipeline for conveying the sampled sample to a target position. The sampling inlet 121 of the sampling conveying pipeline 120 corresponds to and is spaced apart from the sampling outlet 111; that is to say, the sampling inlet 121 and the sampling outlet 111 are not directly in communication, but their positions are matched so that the material output from the sampling outlet 111 can be guided into the sampling inlet 121 through the sampling assembly 130.

[0039] As an example, the material conveying pipeline 110 and the sampling conveying pipeline 120 are arranged side by side, and the sampling conveying pipeline 120 is connected to the side of the material conveying pipeline 110, which is convenient for the layout of the sampling conveying pipeline 120 and for arranging the sampling inlet 121 corresponding to the sampling outlet 111.

[0040] The sampling assembly 130 includes a sampling accommodation chamber 131, an inlet moving mechanism 132, and an outlet moving mechanism 133; the sampling accommodation chamber 131 can be directly or indirectly connected to the moving material conveying pipeline 110.

[0041] The inlet moving mechanism 132 is movably arranged between the sampling outlet 111 and the sampling accommodation chamber 131 and is used to switch the inlet of the sampling accommodation chamber 131 between a communicating state and a blocking state; that is to say, by controlling the inlet moving mechanism 132, the inlet of the sampling accommodation chamber 131 and the sampling outlet 111 can be made to be in a communicating state, such as Figure 2As shown; it is also possible to make both the inlet and the sampling outlet 111 of the sampling accommodation chamber 131 in a partitioned state, such as Figure 1 and Figure 3 shown.

[0042] The outlet moving mechanism 133 is movably arranged between the sampling inlet 121 and the sampling accommodation chamber 131, and is used to switch the outlet of the sampling accommodation chamber 131 between a communicating state and a partitioned state with the sampling inlet 121; that is to say, by controlling the outlet moving mechanism 133, it is possible to make both the outlet of the sampling accommodation chamber 131 and the sampling inlet 121 in a communicating state, or it is also possible to make both the outlet of the sampling accommodation chamber 131 and the sampling inlet 121 in a partitioned state.

[0043] In the above embodiments, the moving modes executed by the inlet moving mechanism 132 and the outlet moving mechanism 133 are not limited. For example, but not limited to, sliding, rotating and other moving modes; the driving modes for their execution are not limited. Generally, corresponding driving motors are configured.

[0044] The pellet feed conveying and sampling device 100 provided by the embodiment of the present application samples from the material conveying pipeline 110 through the sampling assembly 130 and inputs it into the sampling conveying pipeline 120, thereby realizing efficient sampling. In the sampling assembly 130, the inlet and outlet of the sampling accommodation chamber 131 can be controlled to open and close. When sampling from the material conveying pipeline 110, the inlet of the sampling accommodation chamber 131 is controlled to open and the outlet of the sampling accommodation chamber 131 is closed; after maintaining for a specified time, the material fills the sampling accommodation chamber 131; then the inlet of the sampling accommodation chamber 131 is closed and the outlet of the sampling accommodation chamber 131 is opened to input the material in the sampling accommodation chamber 131 into the sampling conveying pipeline 120. The sampling amount in this sampling process is the capacity of the accommodation chamber, and the sampling amount of each sampling can be controlled more precisely.

[0045] In some embodiments, the inlet moving mechanism 132 includes a sealing plate 1321 and a sealing rotating shaft 1322. The sealing rotating shaft 1322 is connected to the material conveying pipeline 110 and is located downstream of the sampling outlet 111. It can be understood that the upstream and downstream relative position relationship between the sealing rotating shaft 1322 and the material conveying pipeline 110 is in reference to the material conveying direction of the material conveying pipeline 110. It should be noted that in the embodiments of the present application, without special explanation, the relative position relationships described by upstream and downstream are all interpreted according to this.

[0046] The sealing plate 1321 is rotatably connected to the material conveying pipeline 110 through the sealing rotating shaft 1322, that is to say, at least a part of the sealing plate 1321 is also located downstream of the sampling outlet 111. The sealing plate 1321 swings between a first position and a second position around the sealing rotating shaft 1322; see Figure 1 and Figure 3When the sealing plate 1321 is located at the first position, the sealing section 1321a of the sealing plate 1321 closes the sampling outlet 111 so as to separate the entrance of the sampling receiving chamber 131 from the sampling outlet 111; see Figure 2 When the sealing plate 1321 is located at the second position, the sealing section 1321a is transferred into the material conveying pipeline 110 to connect the inlet of the sampling containing chamber 131 with the sampling outlet 111 .

[0047] In the above embodiment, the sealing plate 1321 performs the action of opening and closing the sampling outlet 111 in a rotatable manner, which has a simple structure and is easy to control. In addition, when the sealing plate 1321 is located at the second position to open the sampling outlet 111, the sealing section 1321a is located downstream of the upper edge of the sampling outlet 111, which is conducive to the material conveying pipeline 110.

[0048] Continue to see Figure 2 In some embodiments, when the sealing plate 1321 is in the second position, the free end of the sealing section 1321a is located upstream of the rotating end of the sealing section 1321a. That is, with reference to the conveying direction of the material conveying pipeline 110, the sealing section 1321a is tilted at this time, and the free end of the sealing section 1321a is located between the upper edge and the lower edge of the sampling outlet 111.

[0049] In the above embodiment, when the sealing plate 1321 is located in the second position, the sealing section 1321a is located between the upper edge and the lower edge of the sampling outlet 111 in an inclined state, which helps to guide the material in the material conveying pipeline 110 to the entrance of the sampling holding chamber 131, which is beneficial to improve the sampling efficiency and help the sample to better fill the sampling holding chamber 131.

[0050] Continue to see Figure 3 In some embodiments, a sampling guide slope 1321a1 is provided at the free end of the sealing section 1321a, and an end of the sampling guide slope 1321a1 away from the sampling outlet 111 is located upstream of an end of the sampling guide slope 1321a1 close to the sampling outlet 111.

[0051] In the embodiment of the present application, the sampling guide inclined surface 1321 a 1 may be a plane or an arc-shaped surface, which is illustratively a plane inclined toward the sampling outlet 111 .

[0052] In the above embodiment, a sampling guide slope 1321a1 is arranged at the free end of the sealing section 1321a, which is beneficial to guiding the material to the sealing section 1321a, and is beneficial for the sealing section 1321a to guide the material to the entrance of the sampling holding chamber 131, thereby facilitating more efficiently guiding the material to fill the sampling holding chamber 131.

[0053] See also Figure 3, in some embodiments, the sealing plate 1321 further includes a support section 1321b, which is located on the side of the sealing rotating shaft 1322 away from the sealing section 1321a and outside the material conveying pipeline 110; as an example, the sealing section 1321a and the support section 1321b are an integral structure in the sealing plate 1321. Further, their extending directions are the same and form a flat plate body.

[0054] The outer wall of the sampling accommodation chamber 131 includes a fixed plate 1311 and a telescopically deformable part 1312 connected to each other. The edges of the fixed plate 1311 and the telescopically deformable part 1312 are connected to the material conveying pipeline 110 and / or the sampling assembly 130, for example but not limited to, to enclose a closed accommodation cavity.

[0055] Wherein, one end of the telescopically deformable part 1312 away from the fixed plate 1311 is connected to the material conveying pipeline 110 and is located upstream of the sampling outlet 111, for telescopic deformation along with the swing of the sealing plate 1321. As an example, the telescopically deformable part 1312 is configured as an elastic membrane.

[0056] See Figures 3 to 5 , the fixed plate 1311 is connected to one end of the support section 1321b away from the support section 1321b. As an example, the fixed plate 1311 is connected to the upper surface of the support section 1321b and is perpendicular to the support section 1321b; the outlet of the sampling accommodation chamber 131 is opened on the fixed plate 1311. The outlet moving mechanism 133 is movably connected to the fixed plate 1311.

[0057] In this design, the sealing plate 1321 extends to the fixed plate 1311 where the outlet of the sampling accommodation chamber 131 is opened through the support section 1321b, which is beneficial to guiding the material to the vicinity of the outlet of the sampling accommodation chamber 131; when rotating the sealing plate 1321 to close the inlet of the sampling accommodation chamber 131, the sealing plate 1321 drives the material and the fixed plate 1311 to move along with it through the support section 1321b, which can provide kinetic energy for discharging the material, and is also beneficial to more efficiently and thoroughly discharging the material in the sampling accommodation chamber 131; in addition, the support section 1321b also has a supporting effect on the material, which is beneficial to improving the working stability of the sampling assembly 130.

[0058] See Figure 3 , in some embodiments, the sampling conveying pipeline 120 is connected to the side of the material conveying pipeline 110, and the sampling inlet 121 is located below the sampling assembly 130, which is convenient for the sampling assembly 130 corresponding to the sampling outlet 111 to input the material into the sampling conveying pipeline 120; the outlet of the sampling accommodation chamber 131 and the sampling inlet 121 are spaced apart to avoid the sampling conveying pipeline 120 interfering with the rotation of the sealing plate 1321.

[0059] Continue to see Figure 3, in some embodiments, a receiving groove 112 is recessed on the side of the material conveying pipeline 110. When the sealing plate 1321 is in the first position, the supporting section 1321b is received in the receiving groove 112.

[0060] In this design, the receiving groove 112 gives way to the supporting section 1321b, so that when the sealing plate 1321 rotates to the first position, the sealing section 1321a can be in a state substantially parallel to the material conveying pipeline 110, which is beneficial to better seal the sampling outlet 111 by the sealing section 1321a.

[0061] Continue to refer to Figure 4 , in some embodiments, the sampling receiving chamber 131 further includes a surrounding wall 1313, and the surrounding wall 1313 is connected to the upper surface edge of the supporting section 1321b and is also connected to one side edge of the fixing plate 1311 close to the supporting section 1321b.

[0062] As an example, among the remaining edges of the upper surface of the supporting section 1321b that are not connected to the fixing plate 1311, all are connected with the surrounding wall 1313. In the manner of the surrounding wall 1313, the fixing plate 1311, and the surrounding wall 1313, the surrounding wall 1313, the fixing plate 1311, and the surrounding wall 1313 are connected in sequence.

[0063] In this design, the surrounding wall 1313 surrounds the material, which can play a role in supporting and guiding the material, and is beneficial to improving the working stability of the sampling assembly 130.

[0064] Refer to Figures 5 to 7 , in some embodiments, the outlet moving mechanism 133 includes a moving plate 1331, a push rod 1332, and an elastic resetting member 1333.

[0065] The moving plate 1331 is connected to the push rod 1332, and the two are fixedly connected, for example. The push rod 1332 is movably connected to the fixing plate 1311; as an example, in the fixing plate 1311, a sliding groove is provided on the plate body part of the opening of the sampling receiving chamber 131 close to the material conveying pipeline 110, and the push rod 1332 is slidably received in the sliding groove. The elastic resetting member 1333 abuts between the fixing plate 1311 and the push rod 1332. As an example, an elastic resetting groove 1311a is recessed on the side surface of the fixing plate 1311 close to the material conveying pipeline 110, and the elastic resetting groove 1311a communicates with the sliding groove. At least a part of the push rod 1332 extends into the sliding groove, and a resisting flange 1332a is provided at the end of the push rod 1332 away from the moving plate 1331. The elastic resetting member 1333 is a spring, for example. The elastic resetting member 1333 is sleeved on the push rod 1332 and abuts between the bottom of the elastic resetting groove 1311a and the resisting flange 1332a.

[0066] Refer to Figure 7, when the sealing plate 1321 is in the second position, the push rod 1332 protrudes from the side of the fixed plate 1311 close to the material conveying pipeline 110 under the elastic force of the elastic reset member 1333. The push rod 1332 drives the movable plate 1331 to move relative to the fixed plate 1311 toward the side close to the material conveying pipeline 110, so that the movable plate 1331 closes the outlet of the sampling accommodation chamber 131; see Figure 6 , when the sealing plate 1321 is in the first position, the side surface of the material conveying pipeline 110 abuts against and pushes the protruding part of the push rod 1332 to move relative to the fixed plate 1311. The push rod 1332 drives the movable plate 1331 to move relative to the fixed plate 1311 away from the side close to the material conveying pipeline 110, so that the movable plate 1331 opens the outlet of the sampling accommodation chamber 131.

[0067] In the above technical solution, the outlet moving mechanism 133 can be linked with the movement of the sealing plate 1321. Among them, when the sealing plate 1321 rotates to open the sampling outlet 111, the outlet moving mechanism 133 moves to close the outlet of the sampling accommodation chamber 131; when the sealing plate 1321 rotates to close the sampling outlet 111, the outlet moving mechanism 133 moves to open the outlet of the sampling accommodation chamber 131, making the opening and closing of the sampling accommodation chamber 131 simpler; moreover, it can avoid the situation of discharging while feeding into the sampling accommodation chamber 131, which is beneficial to more accurately control the sampling amount.

[0068] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
