Technical Field
[0001] The utility model relates to the technical field of grain storage and transportation, and particularly relates to a movable sample divider with a replaceable feed hopper capacity. Background Technique
[0002] A sample divider is an instrument needed in the process of grain storage and transportation, which has the characteristics of reducing and dividing samples and evenly dividing samples. The bell-type sample divider is a common type among many sample dividers. Its structure includes a sample dividing hopper, sample dividing grids, sample receiving cups, etc. Its working principle is that the uniformly mixed sample evenly flows into the sample dividing grids through the sample dividing hopper. After being separated by the sample dividing grids, it enters different sample receiving cups respectively to realize the sample division. The existing bell-type sample divider has the following disadvantages: First, during the grain storage process, in order to better master the grain quality situation, there are many sampling points, and the capacity of the mixed sample is large, so it needs to be repeated several times to mix the sample evenly; Second, when the sample divider needs to be carried during work, it is very difficult to carry the existing sample divider. Content of the Utility Model
[0003] The purpose of the utility model is to provide a movable sample divider with a replaceable feed hopper capacity, which has the effects of being convenient to carry and the feed hopper being detachable and replaceable.
[0004] The above technical purpose of the utility model is achieved through the following technical solutions: A movable sample divider with a replaceable feed hopper capacity, including a sample inlet hopper, a sample dividing grid connected to the sample inlet hopper, two sample receiving cups, and a moving platform located below the sample dividing grid. The sample dividing grid is provided with two sample outlet openings, and the two sample outlet openings respectively face the two sample receiving cups. There are several brackets between the sample dividing grid and the moving platform. The upper ends of the brackets are fixedly connected to the side walls of the sample dividing grid by bolts. The lower ends of the brackets are formed with spherical parts. The moving platform is fixed with several connecting cylinders, and the connecting cylinders correspond to the brackets one by one. The spherical parts are embedded in the connecting cylinders. The lower ends of the brackets are sleeved with sleeves. The inner wall of the lower end of the sleeve is threadedly connected to the outer wall of the connecting cylinder. The upper end of the sleeve is fixed with a ring part. A middle hole is opened in the middle of the ring part. The bracket passes through the middle hole. Several rollers are installed at the bottom of the moving platform. The sample inlet hopper is threadedly connected to the sample dividing grid.
[0005] By adopting the above technical solutions, the sample inlet hopper is threadedly connected to the sample dividing grid, and different specifications of sample inlet hoppers can be disassembled and replaced according to the number of samples. In this way, when there are more samples, the situation of having to mix the samples several times will not occur.
[0006] When short-distance transportation is needed, since rollers are installed at the bottom of the moving platform, the staff can easily push the sample divider to move.
[0007] When long-distance transportation is required, loosen the bolts to separate the support from the sample dividing grid, and loosen the sleeve to separate the sleeve from the connecting cylinder and the spherical part from the connecting cylinder, so as to separate the sample dividing grid, the support and the moving table, and separate the sample dividing grid from the sampling hopper. After disassembly, it can be transported over a long distance.
[0008] A further setting of the present utility model is that the number of the supports is three, and the supports are evenly distributed around the sample dividing grid.
[0009] By adopting the above technical solution, the support for the sample dividing grid is more stable.
[0010] A further setting of the present utility model is that a locking bolt is threadedly connected to the side wall of the sleeve, a first locking hole is provided on the side wall of the connecting cylinder, a second locking hole is formed on the spherical part, and the locking bolt passes through the first locking hole and is inserted into the second locking hole.
[0011] By adopting the above technical solution, the positions of the sleeve, the connecting cylinder and the spherical part are fixed by the locking bolt.
[0012] A further setting of the present utility model is that the moving table includes a table body and two movable seats. Two movable grooves are formed on the upper end surface of the table body. The movable seats are embedded in the movable grooves. An elastic member is provided between the bottom of the movable groove and the lower end surface of the movable seat. The sample receiving cup is placed on the upper end surface of the movable seat.
[0013] By adopting the above technical solution, before the sampler works, the staff presses the movable seat downward to make it descend, and then places the sample receiving cup on the movable seat. At this time, the sample outlet of the sample dividing grid is located above the sample receiving cup. Then release the movable seat, and the elastic force of the elastic member drives the movable seat and the sample receiving cup to rise. At this time, the sample outlet of the sample dividing grid is located inside the sample receiving cup.
[0014] When the sampler is working, when the sampling hopper is full of samples, the samples are discharged from the sample outlet hopper, and the impact force is relatively large. Since the sample outlet is located inside the sample receiving cup at this time, it can well prevent the samples with a large impact force discharged from the sample outlet from splashing outside the sample receiving cup.
[0015] As the samples in the sampling hopper gradually decrease and the samples in the sample receiving cup gradually increase, the impact force of the samples discharged from the sample outlet gradually decreases, and the sample receiving cup and the movable seat gradually descend, and the sample receiving cup gradually moves away from the sample outlet, so that the situation that the sample outlet is buried in the samples in the sample receiving cup will not occur.
[0016] A further setting of the present utility model is that the elastic member is a spring.
[0017] A further setting of the present utility model is that a braking device is provided at the roller.
[0018] A further setting of the present utility model is that the number of the rollers is four.
[0019] The further setting of the utility model is as follows: The bracket includes an upper tube body, a connecting cylinder fixed at the lower end of the upper tube body, and a lower rod body. The upper end of the lower rod body is inserted into the connecting cylinder and the interior of the upper tube body. A plurality of adjusting holes are formed in the side wall of the lower rod body, and the plurality of adjusting holes are spaced apart along the length direction of the lower rod body. An adjusting bolt is threadedly connected to the side wall of the connecting cylinder, and the end of the adjusting bolt is inserted into the adjusting hole.
[0020] By adopting the above technical solution, rotating the adjusting bolt to disengage it from the adjusting hole can adjust the position of the lower rod body and the upper tube body, and adjust the telescopic length of the bracket as needed to change the length of the bracket.
[0021] The beneficial effects of the utility model are as follows: The sampling hopper of the utility model is threadedly connected with the sample dividing grid, and different specifications of sampling hoppers can be replaced according to the amount of samples, avoiding the situation that the samples need to be mixed several times when the amount of samples is large. The bracket can be telescopically adjusted to change the overall length, and the height of the sample dividing grid can be adjusted as needed. The bottom of the moving table is equipped with rollers, which is convenient for the staff to carry as needed, saving time and improving the sample dividing work efficiency.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0030] A movable sample divider with a replaceable feed hopper capacity, as Figures 1 to 5 shown, includes a sample receiving hopper, a sample dividing grid 2 connected to the sample receiving hopper, two sample receiving cups 3, and a moving platform 4 located below the sample dividing grid 2. Four rollers 6 are installed at the bottom of the moving platform 4, and at least one of the rollers 6 is equipped with a braking device. The sample receiving hopper and the sample dividing grid 2 are connected by threads. The sample dividing grid 2 is provided with two sample outlets 21, and the two sample outlets 21 respectively face the two sample receiving cups 3.
[0031] Three supports 5 are provided between the sample dividing grid 2 and the moving platform 4. The three supports 5 are evenly distributed around the sample dividing grid 2. The upper ends of the supports 5 are fixedly connected to the side walls of the sample dividing grid 2 by bolts. The lower ends of the supports 5 are formed with spherical parts 51. The moving platform 4 is fixed with three connecting cylinders 7, and the connecting cylinders 7 correspond to the supports 5 one by one. The spherical parts 51 are embedded in the connecting cylinders 7. The lower ends of the supports 5 are sleeved with sleeves 52. The inner wall of the lower end of the sleeve 52 is threadedly connected to the outer wall of the connecting cylinder 7. The upper end of the sleeve 52 is fixed with an annular part 54. A middle hole is opened in the middle of the annular part 54, and the support 5 passes through the middle hole. A locking bolt 53 is threadedly connected to the side wall of the sleeve 52. A first locking hole is provided on the side wall of the connecting cylinder 7, and a second locking hole is formed on the spherical part 51. The locking bolt 53 passes through the first locking hole and is inserted into the second locking hole.
[0032] The support 5 includes an upper pipe body 55, an adjusting cylinder 56 fixed to the lower end of the upper pipe body 55, and a lower rod body 57. The upper end of the lower rod body 57 is inserted into the adjusting cylinder 56 and the inside of the upper pipe body 55. A plurality of adjusting holes are opened on the side wall of the lower rod body 57, and the plurality of adjusting holes are spaced apart along the length direction of the lower rod body 57. An adjusting bolt 58 is threadedly connected to the side wall of the adjusting cylinder 56, and the end of the adjusting bolt 58 is inserted into the adjusting hole.
[0033] The mobile station 4 includes a body 41 and two movable seats 43. Two movable grooves 42 are formed in the upper end surface of the body 41.

After the elastic force of the elastic member 44 drives the movable seat 43 and the sample receiving cup 3 to rise, the sample outlet 21 of the sample splitting grid 2 is located inside the sample receiving cup 3 at this time.
[0034] When the sample splitter works, when the sample inlet hopper 1 is full of samples, the samples are discharged from the sample outlet hopper, and the impact force is relatively large. Since the sample outlet 21 is located inside the sample receiving cup 3 at this time, it can well prevent the samples with a large impact force discharged from the sample outlet 21 from splashing outside the sample receiving cup 3.
[0035] As the samples in the sample inlet hopper 1 gradually decrease and the samples in the sample receiving cup 3 gradually increase, the impact force of the samples discharged from the sample outlet 21 gradually decreases. The sample receiving cup 3 and the movable seat 43 gradually descend, and the sample receiving cup 3 gradually moves away from the sample outlet 21, and the situation that the sample outlet 21 is buried in the samples in the sample receiving cup 3 will not occur.
