[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0030] refer to Figure 1-5 The specific embodiment of the utility model provides a hybrid shrinking machine, including:
[0031] The shrinking chassis 2 is rotatably connected to the frame and driven by the motor 1, and the coal flow free fall port 5 is located above the edge of the shrinking chassis 2;
[0032] Conventional material receiving hopper 7, a plurality of conventional material receiving hoppers 7 are connected to the edge of the reduced chassis 2;
[0033] Special material receiving hoppers 6, at least one group of special material receiving hoppers 6 are connected to the edge of the reduction chassis 2, and the coal flow at the free fall port 5 of the coal flow passes through the special material receiving hoppers 6 and through the reduction chassis 2.
[0034] The existing mixed and reduced machine has multiple receiving hoppers of the same model, which can evenly divide the sample into 8 portions, and then take out 2-3 portions as samples, and the remaining 5-6 portions need to be discarded. This process is operated by personnel alone, which affects work efficiency. In this application, by driving the reduction chassis 2 to rotate, the sample is received by the conventional receiving hopper 7, and the remaining coal flow falls into the special receiving hopper 6 and directly passes through the reduction chassis 2 and falls into the discarded material collection device, without the need for personnel to operate each bucket individually, thereby greatly improving work efficiency.
[0035] Further optimization plans also include:
[0036] The funnel 9 is fixedly connected to the inside of the special material receiving hopper 6 , and the bottom of the funnel 9 is fixedly passed through the bottom of the special material receiving hopper 6 and passes through the reduction chassis 2 .
[0037] The main function of the funnel 9 is to allow the coal flow falling from the coal flow free fall port 5 to pass through the special receiving hopper 6 and the reduction chassis 2, and directly fall into the waste material collection device, thereby avoiding the staff from handling the samples that are not to be inspected separately.
[0038] Further optimization plans also include:
[0039] The lower extension plate 4 and the funnel 9 are fixedly passed through the special receiving hopper 6 to form the lower extension plate 4;
[0040] A plurality of blanking openings 8 are circumferentially arranged at the edge of the reduced chassis 2 , and the lower extension plate 4 is fitted into the blanking openings 8 .
[0041] Through the lower extension plate 4, the special receiving hopper 6 can be limited in the drop port 8, and the coal flow can smoothly pass through the drop port 8 and fall into the waste material collection device, thereby improving work efficiency; the axial direction of the lower extension plate 4 and the drop port 8 are both fan-shaped structures, and the lower extension plate 4 is adapted in the drop port 8.
[0042] Further optimization plans also include:
[0043] The upper extension plate 3 is axially fixedly connected to the edge of the reduced chassis 2, and the special receiving hopper 6 and the conventional receiving hopper 7 are respectively arranged on the centripetal side surface of the upper extension plate 3 in contact with each other.
[0044] The main function of the upper extension plate 3 is to further limit the special receiving hopper 6 and the conventional receiving hopper 7 to prevent the centrifugal force during the rotation of the reduction chassis 2 from causing the reduction chassis 2 to separate from the reduction chassis 2, thereby playing a role in safety protection.
[0045] According to a further optimized solution, the height of the lower extension plate 4 is 5-15 mm.
[0046] The height of the lower extension plate 4 is preferably 10 mm, which can effectively limit the special receiving hopper 6 on the reduction chassis 2, thereby facilitating the coal flow to fall into the waste material collection device.
[0047] According to a further optimized solution, the radial thickness of the upper extension plate 3 is 3-7 mm and the height is 10-20 mm.
[0048] The radial thickness of the upper extension plate 3 is preferably 5 mm, and the height is 15 mm. This arrangement can better restrict the special material receiving hopper 6 and the conventional material receiving hopper 7, thereby achieving a better restrictive effect.
[0049] According to the further optimization scheme, the heights of the special receiving hopper 6 and the conventional receiving hopper 7 are both 200-300 mm.
[0050] The special receiving hopper 6 and the conventional receiving hopper 7 have the same outer dimensions, and both are 250 mm in height; the special receiving hopper 6 and the conventional receiving hopper 7 are respectively fan-shaped and placed in a ring structure, and the bottom of the conventional receiving hopper 7 is made of stainless steel plate.
[0051] According to the further optimization scheme, the diameter of the reduced chassis 2 is 650-750 mm and the thickness is 5-9 mm.
[0052] The diameter of the reduced chassis 2 is 700mm and the thickness of the iron plate is 7mm, which ensures the structural strength and stable operation.
[0053] There are 8 receiving hoppers of the same model under the existing mixing and reducing machine, which can evenly divide the sample into 8 portions, then take out 2-3 portions as reserved samples, and discard the remaining 5-6 portions; the position relationship between the special receiving hopper 6 and the conventional receiving hopper 7 is set according to the sampling requirements. In this application, the discarded 5-6 portions of samples can be directly put into the abandoned coal bucket without the need for personnel to operate each bucket separately, thereby greatly improving the work efficiency; overall:
[0054] 1. The present application can place a conventional receiving hopper 7 according to the requirements, and can achieve any reduction ratio of 1 / 8-7 / 8.
[0055] 2. When 1 / 8-7 / 8 of the sample is retained, the remaining discarded sample can be directly discharged from the equipment through the special receiving hopper 6, without the need to take it out and then discard the sample, which greatly improves the work efficiency;
[0056] 3. The present application uses the drop-out opening 8 at the bottom of the reduced chassis 2 and the lower extension plate 4 at the bottom of the funnel 9 to limit the special receiving hopper 6 on the reduced chassis 2 to avoid deviation or falling.

In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
