Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material storage, in particular to a silo with a sampling device. Background Art
[0002] Warehouses for storing bulk materials are divided into two categories: agricultural silos and industrial silos. Agricultural silos are used to store granular and powdery materials such as grain and feed; industrial silos are used to store bulk materials such as coke, cement, salt, and sugar.
[0003] When using a silo to store materials, it is necessary to regularly sample and detect the materials in the silo to ensure the quality, safety, and suitability of the storage conditions of the materials. For example, when sampling and detecting the grain stored in the silo, it is necessary to detect data such as the quality of the grain (detection of color and smell, mold spores, etc.), storage environment (temperature and humidity, condensation and caking), and pest situation for detection and statistics.
[0004] The current silos do not have an independent sampling mechanism, so when sampling, it is necessary to use a corresponding feeder to discharge a part of the materials in the silo as a sample. However, since the feeder of the silo has a large one-time feeding volume, the sample volume taken is large, which easily causes sample waste and does not meet the sampling purpose.
[0005] Therefore, in view of this, the inventor proposes a silo with a sampling device to solve the above problems. Summary of the Utility Model
[0006] The purpose of the utility model is to provide a silo with a sampling device to solve the problem that in the prior art, the silo does not have an independent sampling mechanism, making sampling inconvenient.
[0007] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
[0008] A silo with a sampling device includes a support base and a silo body arranged on the support base. A feeder is provided at the bottom of the silo body. A fixed cylinder is fixedly arranged on the inner wall of the silo body. A rotatable cylinder adapted to it is rotatably connected inside the fixed cylinder. One end of the rotatable cylinder protrudes outside the silo body. A sampling cylinder is further included. The sampling cylinder is movably connected and can be received inside the rotatable cylinder. A first sample inlet is opened at the top of the fixed cylinder. A second sample inlet is opened at the position corresponding to the first sample inlet on the rotatable cylinder. A sample holding groove is arranged inside the sampling cylinder. A third sample inlet is opened at the position corresponding to the first sample inlet on the top of the sampling cylinder. The third sample inlet communicates the sample holding groove with the outside of the sampling cylinder.
[0009] Further, transverse grooves are axially provided on the surface of the sampling cylinder, and annular grooves are circumferentially provided. The transverse grooves intersect with the annular grooves. A first clamping block is fixedly provided on the inner wall of the rotating cylinder corresponding to the position of the annular groove. When the second sampling port communicates with the first sampling port, the first clamping block is located outside the transverse groove.
[0010] Further, the transverse grooves penetrate through the sampling cylinder. The inner end of the sampling cylinder protrudes outside the rotating cylinder and is located inside the fixed cylinder. A second clamping block is fixedly provided on the inner wall of the fixed cylinder corresponding to the inner end of the sampling cylinder. The second clamping block is located inside the transverse groove.
[0011] Further, the inner end of the sampling cylinder is magnetically connected to the inner wall of the fixed cylinder.
[0012] Further, a sliding block adapted thereto is slidably connected in the sample holding groove. A regulating member is rotatably connected to the sliding block and penetrates through the sampling cylinder and extends outside the silo body. The regulating member is threadedly connected to the sampling cylinder. The sliding block cannot rotate in the sample holding groove.
[0013] Further, a locknut is provided between the regulating member and the outer end of the sampling cylinder. The locknut is threadedly connected to the regulating member.
[0014] Further, a pressure stabilizing groove is provided on the inner wall of the rotating cylinder. One end of the pressure stabilizing groove communicates with the third sampling port, and the other end communicates with the annular groove.
[0015] Further, a torsion member is fixedly sleeved on the surface of the end of the rotating cylinder located outside the silo body.
[0016] Further, the torsion member is a handwheel, a crank or a runner.
[0017] Further, a diagonal brace is provided between the fixed cylinder and the silo body. Two ends of the diagonal brace are respectively fixedly connected to the bottom of the fixed cylinder and the inner wall of the silo body.
[0018] Advantages of the utility model:
[0019] In this application, through the arrangement of the fixed cylinder, the rotating cylinder and the sampling cylinder, the fixed cylinder, the rotating cylinder and the sampling cylinder jointly form a sampling device. When there is material inside the silo body, rotate the rotating cylinder to align and communicate the second sampling port with the first sampling port, and the material can fall into the interior of the sample holding groove through the first sampling port, the second sampling port and the third sampling port. Then rotate the rotating cylinder again to stagger the second sampling port from the first sampling port. The rotating cylinder seals the first sampling port, and then pull out the sampling cylinder from the rotating cylinder, and the material inside the silo body can be sampled in small amounts. The structure is simple and the operation is convenient. Description of the drawings

[0034] This embodiment proposes a silo with a sampling device, as Figures 1 to 5 shown, which includes a support base 6 and a silo body 1 fixedly arranged on the support base 6. In this embodiment, the silo body 1 is used to hold materials. The silo body 1 includes a cylindrical barrel 11 and a conical blanking hopper 12 fixedly arranged at the bottom of the barrel 11. The blanking hopper 12 is used to guide the materials when discharging the materials. A blanking device 13 is fixedly connected to the bottom of the blanking hopper 12, which is used to discharge the materials inside the barrel 11 and the blanking hopper 12 when starting to work. The support base 6 is fixedly installed on the outside of the barrel 11. The bottom of the support base 6 is evenly and fixedly connected with columns 61 for supporting and fixing the support base 6. The structures of the silo body 1 and the support base 6 have been fully disclosed in the prior art, and will not be elaborated here.
[0035] A fixed cylinder 2 is horizontally fixed on the inner wall of the silo body 1. A rotating cylinder 3 that is adapted is rotatably connected inside the fixed cylinder 2. The outer wall of the rotating cylinder 3 is in contact with the inner wall of the fixed cylinder 2. One end of the rotating cylinder 3 protrudes outside the silo body 1. In this embodiment, a cavity is provided inside the fixed cylinder 2. One end of the fixed cylinder 2 is closed and the other end is open. The open end of the fixed cylinder 2 is welded to the inner wall of the silo body 1, and the closed end faces the center of the silo body 1. The rotating cylinder 3 is rotatably connected to the side wall of the silo body 1 through a bearing, and both ends of the rotating cylinder 3 are open.
[0036] It further includes a sampling cylinder 4. The sampling cylinder 4 is movably connected and can be received inside the rotating cylinder 3. The outer wall of the sampling cylinder 4 is in contact with the inner wall of the rotating cylinder 3. A first sampling port 21 is opened at the top of the fixed cylinder 2. A second sampling port 31 is opened at the corresponding position of the rotating cylinder 3 for the first sampling port 21. The first sampling port 21 and the second sampling port 31 are adapted to each other. A sample holding groove 42 is provided inside the sampling cylinder 4. A third sampling port 41 is opened at the corresponding position of the top of the sampling cylinder 4 for the first sampling port 21. The third sampling port 41 communicates the sample holding groove 42 with the outside of the sampling cylinder 4. In this embodiment, both ends of the sampling cylinder 4 are closed. The cross-section of the sample holding groove 42 is not circular. The inner end of the sample holding groove 42 is adapted to the first sampling port 21, and the outer end extends along the axial direction of the sampling cylinder 4 outside the silo body 1.
[0037] The surface of the sampling cylinder 4 is axially penetrated with a laterally recessed transverse groove 43 and circumferentially provided with an inwardly recessed annular groove 44. In this embodiment, three annular grooves 44 are axially spaced along the sampling cylinder 4, and the three annular grooves 44 are respectively located at both ends and the middle of the sampling cylinder 4. The three annular grooves 44 all intersect with the transverse groove 43. Corresponding to each annular groove 44 position on the inner wall of the rotating cylinder 3, a first clamping block 32 is fixedly provided. The three first clamping blocks 32 are located on the same straight line. The first clamping block 32 is in sliding fit with both the annular groove 44 and the transverse groove 43. When the second sampling port 31 is aligned and communicated with the first sampling port 21, the first clamping block 32 is located outside the transverse groove 43. When the rotating cylinder 3 rotates until the first clamping block 32 is located at the intersection of the transverse groove 43 and the annular groove 44, the rotating cylinder 3 seals the third sampling port 41. In this embodiment, when the rotating cylinder 3 rotates until the three first clamping blocks 32 are all located at the intersection of the transverse groove 43 and the annular groove 44, the sampling cylinder 4 can be withdrawn from the rotating cylinder 3. When the three first clamping blocks 32 are not located at the intersection of the transverse groove 43 and the annular groove 44, under the action of the first clamping block 32, the sampling cylinder 4 cannot be taken out of the rotating cylinder 3.
[0038] The inner end of the sampling cylinder 4 protrudes outside the rotating cylinder 3 and is located inside the fixed cylinder 2. Corresponding to the inner end of the sampling cylinder 4 on the inner wall of the fixed cylinder 2, a second clamping block (not shown in the figure) is fixedly provided. The second clamping block is located in the transverse groove 43. In this embodiment, the cross-section of the inner cavity of the fixed cylinder 2 is stepped. Its large-diameter section is used to install the rotating cylinder 3, and the small-diameter section is used to install the inner end of the sampling cylinder 4. By providing the second clamping block, when the sampling cylinder 4 is completely inserted into the rotating cylinder 3, the second clamping block always remains in the transverse groove 43 to limit the rotation of the sampling cylinder 4 and prevent the sampling cylinder 4 from rotating with the rotating cylinder 3 during the sampling process, which affects the sampling effect.
[0039] The inner end of the sampling cylinder 4 is magnetically connected to the inner wall of the fixed cylinder 2. On the one hand, it can limit the rotation of the sampling cylinder 4 in the rotating cylinder 3. On the other hand, it is convenient for the positioning of the sampling cylinder 4.
[0040] A slider 45 that fits snugly is slidably connected within the sample holding tank 42. A regulating member 46 that passes through the sampling cylinder 4 and extends outside the silo body 1 is rotatably connected to the slider 45. The regulating member 46 is threadedly connected to the sampling cylinder 4, and the slider 45 cannot rotate within the sample holding tank 42. In this embodiment, the regulating member 46 is a bolt. Since the cross-sectional shape of the slider 45 is not circular, the slider 45 cannot rotate within the sample holding tank 42. A threaded hole is provided at one end of the sampling cylinder 4 that is outside the silo body 1, and a through-hole is provided at one end of the slider 45 facing the threaded hole. One end of the bolt is located outside the sampling cylinder 4, and the other end passes through the threaded hole and is inserted into the through-hole. A locknut 47 is also provided between the outer end of the bolt and the sampling cylinder 4. The locknut 47 is threadedly connected to the bolt, and the locknut 47 can increase the connection stability between the bolt and the sampling cylinder 4. By rotating the bolt, the slider 45 can be driven to slide within the sample holding tank 42, thereby adjusting the size of the sample holding tank 42 and the sampling volume.
[0041] In the above embodiment, a scale (not shown in the figure) can also be provided at one end of the slider 45 away from the sample holding tank 42. A perforation for the scale to pass through is provided at the outer end of the sampling cylinder 4. When the slider 45 moves horizontally to adjust the size of the sample holding tank 42, the scale moves accordingly. With such a structural design, when the staff adjusts the size of the sample holding tank 42, they can clearly, intuitively, and efficiently judge the specific size of the sample holding tank 42 by observing the scale markings on the scale, improving work efficiency.
[0042] A pressure stabilizing groove 33 that is recessed inward is provided along the axial direction of the inner wall of the rotating cylinder 3. One end of the pressure stabilizing groove 33 communicates with the third sample inlet 41, and the other end communicates with the annular groove 44. In this embodiment, the pressure stabilizing groove 33 is located between the innermost annular groove 44 and the third sample inlet 41. When the rotating cylinder 3 rotates to the position where the first latch 32 is located at the intersection of the annular groove 44 and the transverse groove 43, the rotating cylinder 3 seals the third sample inlet 41. At this time, the pressure stabilizing groove 33 is located at the top of the rotating cylinder 3, and the pressure stabilizing groove 33 connects the sample holding tank 42 with the innermost annular groove 44. In this embodiment, the depth of the transverse groove 43 is greater than the depth of the annular groove 44. With such a structural design, when the slider 45 moves left and right to adjust the size of the sample holding tank 42, the sample holding tank 42 can be connected to the outside through the pressure stabilizing groove 33, the innermost annular groove 44, and the transverse groove 43 to ensure that the air pressure inside and outside the sampling cylinder 4 remains balanced.
[0043] A torsion member 34 is fixedly sleeved on the surface of the end of the rotating cylinder 3 that is outside the silo body 1. The torsion member 34 is a handwheel, a crank, or a rotating wheel, which is convenient for the staff to rotate the rotating cylinder 3.
[0044] An inclined strut 5 is provided between the fixed cylinder 2 and the silo body 1. The two ends of the inclined strut 5 are respectively fixedly connected to the bottom of the fixed cylinder 2 and the inner wall of the silo body 1, thereby improving the stability of the fixed cylinder 2.
[0045] In the above embodiment, the sampling device can be arranged at different heights of the silo body 1 according to actual conditions, so as to sample materials at different heights inside the silo body 1 .
[0046] Working principle:
[0047] When materials are filled inside the silo body 1, in the normal state, the rotating cylinder 3 separates the first sample inlet 21 and the third sample inlet 41, the second sample inlet 31 is located on the right side of the rotating cylinder 3, and the first clamping block 32 is located at the intersection of the transverse groove 43 and the annular groove 44. The sampling cylinder 4 is completely inserted into the rotating cylinder 3, and the inner end of the sampling cylinder 4 is magnetically attracted in the fixed cylinder 2, and the second clamping block 22 is located in the transverse groove 43. Under the limiting action of the second clamping block 22, the sampling cylinder 4 can only move axially along the rotating cylinder 3 and will not rotate; at the same time, the pressure-stabilizing groove 33 connects the sample containing groove 42 with the innermost annular groove 44, and the sample containing groove 42 is connected to the outside through the pressure-stabilizing groove 33, the innermost annular groove 44, and the transverse groove 43 to ensure that the air pressure inside and outside the sampling cylinder 4 remains balanced.
[0048] Before sampling, according to actual conditions, the adjusting member 46 is rotated, and the slider 45 is horizontally moved in the sample holding slot 42 to adjust the size of the sample holding slot 42, thereby controlling the sampling amount.
[0049] When sampling, the twisting piece 34 is rotated ninety degrees counterclockwise, and the second sample inlet 31 connects the first sample inlet 21 and the third sample inlet 41. The material falls into the sample holding slot 42 through the first sample inlet 21, the second sample inlet 31, and the third sample inlet 41 in turn. At this time, the first clamping block 32 is located at the bottom of the rotating cylinder 3. Under the axial limiting action of the first clamping block 32 and the rotation limiting action of the second clamping block 22, the sampling cylinder 4 is completely positioned to avoid operating errors by the staff, which may cause the sampling cylinder 4 to move during the process of the material falling into the sample holding slot 42, thereby affecting the sampling.
[0050] After the sample is taken from the sample holding groove 42, the rotating cylinder 3 is rotated ninety degrees clockwise by the twisting member 34, the first sample inlet 21 and the third sample inlet 41 are separated, and the first clamping block 32 is located at the intersection of the transverse groove 43 and the annular groove 44. At this time, the sampling cylinder 4 can be directly pulled out through the adjusting member 46 to obtain the required sample. After taking out the sample, the sampling cylinder 4 is reinserted into the rotating cylinder 3. The structure is ingenious and the operation is simple.
[0051] It should be noted that during the above sampling process, a small amount of material may remain in the second sampling port 31 each time sampling is performed. When the sampling cylinder 4 is completely withdrawn from the rotating cylinder 3, this part of the material will fall into the rotating cylinder 3. To avoid affecting the next sampling, a vacuum negative pressure device (such as a vacuum cleaner) can be used in combination to adsorb and clean the material inside the rotating cylinder 3 each time after the sampling cylinder 4 is withdrawn. At the same time, the first sampling port 21 can also be set near the side wall of the silo body 1, the inner end of the sampling cylinder 4 can be extended, and the number and spacing of the annular grooves 44 can be reasonably set. In this way, when the sample receiving groove 42 of the sampling cylinder 4 is outside the rotating cylinder 3, the sampling cylinder 4 can just rotate inside the rotating cylinder 3, and the outer wall of the inner end of the sampling cylinder 4 remains in contact with the inner wall at the second sampling port 31 of the rotating cylinder 3, pour out the sample, rotate the sampling cylinder 4 back and insert it into the rotating cylinder 3 again, so that the material located in the second sampling port 31 will not affect the sampling process.
[0052] The above embodiments are only preferred embodiments given to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention.
