Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vehicle samplers, and particularly relates to a waste material collection device for a vehicle sampler. Background Art
[0002] In the whole coal sampling, preparation and analysis process of a thermal power plant, compared with manual sampling, mechanical sampling is not only safe and reliable, has low labor intensity and high work efficiency, but also has strong sampling randomness, better meets the requirements of national standards, and is not affected by human factors. However, unreasonable design or defects of mechanical equipment in the use process will increase the labor intensity of people. For example, if the sampler is not reasonably designed, during the sampling process near the edge of the carriage, the waste material is seriously scattered outside the carriage, with large dust and environmental unfriendliness. At the same time, it also increases the labor intensity of manual cleaning and affects the working efficiency of the equipment.
[0003] Since the current vehicle sampler uses a bridge type, as Figure 8 shown, it mainly includes a lifting motor, a rotating motor, a sample collector, a spiral drill rod and an outer box body. During sampling, the spiral drill rod rotates to collect the coal samples of the entire cross-section of the carriage. The spiral drill rod is wrapped by a metal outer cylinder, and there are a coal sample collection port and a waste material port above the outer cylinder. The whole sampling device is outside a rectangular box body. When the spiral drill rod samples, the coal samples will move upward from bottom to top through the spiral blades and gush out to the collection port and the blanking port. At this time, the coal samples gushing out from the collection port will fall into the collector and be transported to the sample collection bucket through a belt.
[0004] The coal samples gushing out from the waste material port will fall into the carriage through the inside of the outer box body. However, when the sampling point is allocated to a position close to the edge of the carriage, some coal samples will fall outside the carriage, and the accumulated coal falling outside needs to be manually cleaned. Each time of cleaning requires the equipment to be shut down, which brings great trouble to the work. Content of the Utility Model
[0005] Aiming at the above technical problems, the utility model provides a waste material collection device for a vehicle sampler, which can temporarily store and collect the coal gushing out from the waste material port to prevent it from directly gushing out and causing spillage outside.
[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows:
[0007] A waste material collection device for a vehicle sampling machine, comprising an outer box of the sampling machine, a collection baffle, a dust-proof cylinder and a driving device. The collection baffle includes a first baffle and a second baffle which are oppositely arranged. After the first baffle and the second baffle are closed, a collection baffle with a through hole in the middle is formed. Both the first baffle and the second baffle are located inside the outer box of the sampling machine and are hinged to the outer box of the sampling machine. Hinge shafts are provided on the first baffle and the second baffle respectively. The dust-proof cylinder is slidably connected to the outer box of the sampling machine. The first baffle and the second baffle are respectively connected to the dust-proof cylinder through a linkage mechanism. The dust-proof cylinder is moved by the driving device. When the dust-proof cylinder moves, it drives the first baffle and the second baffle to open and close.
[0008] The driving device adopts a telescopic cylinder. Two ends of the telescopic cylinder are respectively hinged to the dust-proof cylinder and the outer box of the sampling machine.
[0009] The telescopic cylinder adopts any one of an electric telescopic cylinder, a pneumatic telescopic cylinder or a hydraulic telescopic cylinder.
[0010] The linkage mechanism includes a gear and a rack. Gears are fixedly connected to the hinge shafts of the first baffle and the second baffle respectively. Each gear corresponds to a rack and meshes with it. The rack is fixedly connected to the dust-proof cylinder.
[0011] A connecting cylinder is provided at the bottom of the dust-proof cylinder. A shielding curtain is fixed to the connecting cylinder. The material of the shielding curtain is rubber.
[0012] The connecting cylinder is slidably connected to the dust-proof cylinder. A return spring is provided at the sliding connection. The connecting cylinder is fixedly connected with a support leg. The lower end of the support leg is lower than the lower end of the shielding curtain and there is a gap.
[0013] The connecting cylinder is slidably connected to the dust-proof cylinder through a guide post. Connecting ears are provided on both the connecting cylinder and the dust-proof cylinder. The lower end of the guide post is fixedly connected to the connecting ear on the connecting cylinder. The upper end of the guide post passes through the connecting ear on the dust-proof cylinder and extends out and is fixedly connected with a limit block. The return spring is sleeved outside the guide post.
[0014] Compared with the prior art, the beneficial effects of the present utility model are:
[0015] The space inside the outer box of the sampling machine can be shielded by closing the first baffle and the second baffle, so that a large amount of overflowing coal is intercepted inside the outer box of the sampling machine, avoiding its direct spillage. After the sampling machine drives the outer box of the sampling machine to move to the middle position of the carriage, the first baffle and the second baffle are opened to discharge the overflowing coal to the middle of the carriage. The dust-proof cylinder is moved by the driving device. When the dust-proof cylinder moves, it drives the first baffle and the second baffle to open and close; that is, the linkage between the two can be realized. During the discharging process, the downward movement of the dust-proof cylinder plays a role in dust prevention.
[0016] A movable connecting cylinder is provided, which contacts the top of the coal seam in the carriage through the support legs, ensuring an interval between the shielding curtain and the bottom of the coal seam; this avoids affecting the discharge of overflow coal. Description of the Drawings

Detailed Embodiment
[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0027] Such as Figures 1-7As shown in the figure, a waste material collection device for a vehicle sampling machine includes a sampling machine outer box 1, a collection baffle 2, a dust-proof cylinder 3, and a driving device 4. The collection baffle 2 includes a first baffle 5 and a second baffle 6 which are arranged oppositely. After the first baffle 5 and the second baffle 6 are closed, a collection baffle 2 with a through hole 7 in the middle is formed. The structure of the through hole 7 is for cooperation with the spiral drill rod. That is, after the first baffle 5 and the second baffle 6 are closed, the space inside the sampling machine outer box 1 can be blocked; a large amount of overflowing coal is intercepted inside the sampling machine outer box 1.
[0028] Specifically: Both the first baffle 5 and the second baffle 6 are located inside the sampling machine outer box 1 and are hinged to the sampling machine outer box 1. Corresponding hinge shafts 8 are fixed on the first baffle 5 and the second baffle 6. The hinge shafts 8 are hinged to the sampling machine outer box 1 and extend through the sampling machine outer box 1.
[0029] The dust-proof cylinder 3 is slidably connected to the sampling machine outer box 1. The first baffle 5 and the second baffle 6 are respectively connected to the dust-proof cylinder 3 through a linkage mechanism. That is, when the driving device 4 drives the dust-proof cylinder 3 to move, the first baffle 5 and the second baffle 6 can be driven to open and close.
[0030] During sampling, the dust-proof cylinder 3 moves upward and drives the first baffle 5 and the second baffle 6 to close through the linkage mechanism; so that during the sampling process, the coal samples gushing out from the waste material outlet will be largely blocked inside the sampling machine outer box 1 and will not be directly discharged.
[0031] After sampling, the sampling machine moves to the middle of the carriage; then the dust-proof cylinder 3 moves downward and drives the first baffle 5 and the second baffle 6 to open through the linkage mechanism; the intercepted coal is discharged to the middle of the carriage through the sampling machine outer box 1, thereby reducing the spillage of coal. At the same time, due to the downward movement of the dust-proof cylinder 3, it can play a role in blocking and suppressing dust.
[0032] Furthermore, the driving device 4 adopts a telescopic cylinder. The two ends of the telescopic cylinder are respectively hinged to the dust-proof cylinder 3 and the sampling machine outer box 1. That is, the up and down movement of the dust-proof cylinder 3 is realized through the expansion and contraction of the telescopic cylinder.
[0033] Specifically: The telescopic cylinder can be any one of an electric telescopic cylinder, a pneumatic telescopic cylinder, or a hydraulic telescopic cylinder according to needs.
[0034] Furthermore, the linkage mechanism includes a gear 9 and a rack 10; gear 9s are fixedly connected to the hinge shafts 8 (extended ends) of the first baffle 5 and the second baffle 6; each gear 9 corresponds to a rack 10 and meshes with it; the rack 10 is fixedly connected to the dust-proof cylinder 3.
[0035] When the up and down movement of the dust-proof cylinder 3 is realized through the expansion and contraction of the telescopic cylinder, the rack 10 moves, thereby driving the gear 9, the hinge shaft 8, and the corresponding first baffle 5 and second baffle 6 meshed with it to rotate, thus realizing linkage.
[0036] Furthermore, in order to improve the effect of suppressing dust, a connecting cylinder 11 is provided at the bottom of the dust-proof cylinder 3, and a shielding curtain 12 is fixed to the connecting cylinder 11; the material of the shielding curtain 12 is rubber.
[0037] Furthermore, in order to prevent the shielding curtain 12 from contacting the top of the coal layer in the carriage and affecting the discharge of overflow coal after the dust-proof cylinder 3 moves downward. Therefore, the connecting cylinder 11 is slidably connected to the dust-proof cylinder 3, and a return spring 13 is provided at the sliding connection; the connecting cylinder 11 is fixedly connected with a support leg 14; the lower end of the support leg 14 is lower than the lower end of the shielding curtain 12 and there is a gap.
[0038] That is, when the dust-proof cylinder 3 moves downward and the support leg 14 contacts the top of the coal layer in the carriage (the return spring 13 is compressed), it can drive the connecting cylinder 11 and the shielding curtain 12 to move upward; so that there is a gap between the shielding curtain 12 and the top of the coal layer; avoiding affecting the discharge of overflow coal.
[0039] Furthermore, various structures can be used to achieve the sliding connection between the connecting cylinder 11 and the dust-proof cylinder 3; preferably, the following structure is adopted:
[0040] The connecting cylinder 11 is slidably connected to the dust-proof cylinder 3 through a guide post 15, and corresponding connecting ears 16 are provided on both the connecting cylinder 11 and the dust-proof cylinder 3; the lower end of the guide post 15 is fixedly connected to the connecting ear 16 on the connecting cylinder 11, and the upper end of the guide post 15 passes through the connecting ear 16 on the dust-proof cylinder 3 and extends out and is fixedly connected with a limit block 17; the limit block 17 can contact the connecting ear 16 on the dust-proof cylinder 3, thereby preventing the guide post 15 from separating from the connecting ear 16 on the dust-proof cylinder 3. The return spring 13 is sleeved outside the guide post 15, and both ends of the return spring 13 are in contact with the two connecting ears 16 respectively.
[0041] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments.
