Description

Technical Field

[0001] The utility model relates to the technical field of train sampling devices, in particular to an improved storage hopper of a train sampling machine. Background Art

[0002] During the train sampling process, after the sampling head collects samples from the train carriage, the samples are sent into the storage hopper. The storage hopper of the train sampling machine is a sample storage device of the train sampling machine, which has the functions of temporarily storing samples, measuring the weight of a single sampling and the total weight of the samples, and measuring the height of the sample material in the storage device during the sampling process of the train sampling machine.

[0003] The current storage hoppers of sampling machines have the following problems:

[0004] 1. The storage hopper is prone to sticking materials, and coal blockage occurs frequently during use. When the materials enter the storage hopper, due to certain reasons, the materials cannot flow normally or the flow rate decreases significantly, resulting in the accumulation of materials in the storage hopper. For example, as the materials gather in the storage hopper, there may be larger particles in the materials, and these particles will form blockages in the storage hopper. At the same time, the materials with higher humidity in the materials are prone to adhere to the inner wall of the storage hopper or form lumps, resulting in blockages. In addition, viscous materials are also prone to accumulate in the storage hopper, forming blockages, all of which will cause the phenomenon of material blockage in the current storage hopper;

[0005] 2. The storage hopper lacks detection devices and cannot judge the occurrence of coal blockage in time. Under normal circumstances, the train sampling machine will work according to the set sampling frequency and sampling volume during the sampling process. If coal blockage occurs in the storage hopper, the sampling volume may gradually decrease. However, since the process may be relatively slow, it may be difficult for the operator to immediately notice this change. At the same time, the sampling head may encounter an increase in resistance or abnormal operation during the sampling process, resulting in abnormal operation of the sampling head.

[0006] Therefore, an improved storage hopper of a train sampling machine is invented to solve the problems that the current storage hopper of the sampling machine is prone to sticking materials, coal blockage occurs frequently during use, and at the same time, the storage hopper lacks detection devices and cannot judge the occurrence of coal blockage in time.

[0030] As Figures 1 to 4 shown in the improved new train sampling machine storage bin, including a hopper 1. Specifically, in one embodiment, the hopper 1 includes four adjacent side wall plates 2 that enclose a square shape and a discharging mechanism 3 located at the bottom end of the side wall plates 2. A discharging port is provided at the lower end of the hopper 1. In this embodiment, the hopper 1 is made of stainless steel material. By enlarging the size of the hopper 1, the total storage capacity of the materials in the hopper 1 can be increased. The materials are stored in the hopper 1 and discharged through the discharging port at its bottom.

[0031] The discharging mechanism 3 includes a flap 4 that can close and open the discharging port. The flap 4 is hinged to the outside of the hopper 1. The flap 4 serves as the "door panel" at the bottom of the hopper 1. By controlling its swing, the discharging and loading processes are realized.

[0032] As Figures 1 to 4 shown in the improved new train sampling machine storage bin, specifically, in one embodiment, two proximity switch assemblies 5 are fixedly connected to the hopper 1 for limiting the swing position of the flap 4. When the flap 4 closes the discharging port, it cooperates with one of the proximity switch assemblies 5. When the flap 4 opens the discharging port, it cooperates with the other proximity switch assembly 5. In this embodiment, the swing angle of the flap 4 is detected by the proximity switch assemblies 5. In this embodiment, when the flap 4 closes the discharging port of the hopper 1, that is, when the flap 4 swings to the lowest end, the proximity switch assembly closest to it detects the position of the flap 4 at this time and sends the data to the control system. The control system can control other components to perform the loading process. When the flap 4 opens the discharging port of the hopper 1, that is, when the flap 4 swings to the highest end, the proximity switch assembly 5 closest to it can detect the position of the flap 4 at this time.

[0033] As Figures 1 to 4 shown in the improved new train sampling machine storage bin, specifically, in one embodiment, the bottom of the hopper 1 is set in an arc shape, and an arc-shaped portion that can cooperate with the bottom of the hopper 1 is provided on the flap 4, which is convenient for the swing of the flap 4 and the closing of the hopper 1.

[0034] As Figures 1 to 4 shown in the improved new train sampling machine storage hopper, in a specific embodiment, one side of the hopper 1 is hingedly connected with a swingable electric telescopic push rod 6, and the output end of the electric telescopic push rod 6 is hingedly connected with the flap 4. The telescopic movement of the electric telescopic push rod 6 can drive the flap 4 to swing, facilitating the automatic control of the flap 4;

[0035] As Figures 1 to 4 shown in the improved new train sampling machine storage hopper, in a specific embodiment, it further includes a detection mechanism 7 for detecting the material condition inside the hopper 1, including a fixed cover 8. The fixed cover 8 is arranged on the top of the hopper 1, and a feed inlet 9 is opened at the upper end of the fixed cover 8. The material is input into the hopper 1 through the feed inlet 9. A plurality of weighing sensors 10 are fixedly connected between the fixed cover 8 and the hopper 1. The upper end of each weighing sensor 10 is connected with the fixed cover 8, and the lower end of each weighing sensor 10 is connected with the hopper 1. An ultrasonic ranging sensor 11 is fixedly connected to the fixed cover 8 for detecting the height of the material inside the hopper 1. In this embodiment, the number of weighing sensors 10 is set to four, and the four weighing sensors 10 are respectively located at the four corners of the top of the hopper 1 for measuring the weight of each sampled sample. The ultrasonic ranging sensor 11 is fixedly installed on the top of the fixed cover 8, and the irradiation direction of the internal sensor thereof is the inside of the hopper 1. A protective cover is arranged outside the ultrasonic ranging sensor 11 for protecting it. Through the weighing sensors 10 and the ultrasonic ranging sensor 11, it is convenient to measure the weight of each sampled sample, and at the same time, it can detect the height of the material inside the hopper 1, facilitating the monitoring of the situation inside the hopper 1 and avoiding ineffective sampling.

[0036] As Figures 1 to 4 shown in the improved new train sampling machine storage hopper, in a specific embodiment, the flap 4 includes a bottom plate arranged at its bottom and side plates 12 connected to the upper left and right sides of the bottom plate. The two side plates 12 are respectively hingedly connected to the side wall plates 2. The left and right sides of the hopper 1 are respectively fixedly connected with bearing seats 13. The two side plates 12 are respectively rotationally connected to the bearing seats 13 on their corresponding sides through bearings. The flap 4 swings around the bearing in the bearing seat 13 during rotation, thereby closing and opening the discharge port.

[0037] As Figures 1 to 4 shown in the improved new train sampling machine storage hopper, in a specific embodiment, a PE lining layer 14 is fixedly connected to the inner side of the hopper 1. The PE lining layer 14 is an anti - sticking material for preventing the material from adhering to the inner wall of the hopper 1.

[0038] As Figures 1 to 4The improved new train sampling machine storage bin shown, in a specific embodiment, a vibration motor 15 is fixedly connected to the outside of the hopper 1. The vibration motor 15 is a prior art and its structure will not be described here. By the vibration motor 15, the hopper 1 vibrates, thereby vibrating the materials inside the hopper 1, preventing the phenomenon of sticking materials, and at the same time facilitating the uniform loading of the materials inside the hopper 1.

[0039] As Figures 1 to 4 The improved new train sampling machine storage bin shown, in a specific embodiment, a receiving hopper 16 separated from the lower end of the hopper 1 is provided to facilitate the receiving of materials.
