Description

Technical Field

[0001] The invention relates to the technical field of metal sampling, in particular to an alloy sampling and pouring device. Background Art

[0002] Precious alloys are productive raw materials in the special metal smelting industry. They come in many varieties, are used in large quantities, and are expensive. They are usually packaged in metal barrels. During quality inspection, the entire barrel must be poured out, and a comprehensive inspection must be conducted to determine whether there are any foreign substances or adulterations. Samples must be taken for physical and chemical analysis.

[0003] The specific operation is: use a crane to hang the alloy barrel, two people hold the barrel body and tilt it to pour it into another empty barrel, stop while pouring, and the sampling personnel randomly take samples, or pour all on a clean ground, and then shovel the alloy back into the barrel after sampling. The sampling work requires 4 to 5 people and the crane to cooperate. In addition, in the production feeding link, since various alloys need to be added in proportion according to production requirements, it is generally manually turned over on the spot to pour out the alloy, shovel out an appropriate amount and weigh it until it meets the standard weight, and the remaining alloy is shoveled back into the original barrel.

[0004] At present, the sampling and production feeding process rely on overhead crane and manual cooperation to pour out the precious alloy in the iron barrel.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1-Figure 7 As shown, an embodiment of the present invention provides an alloy sampling and discharging device, comprising a trolley 1, a boom linkage mechanism, a guide rail mechanism, an iron barrel bracket 7, a receiving hopper 9, and a telescopic driving member; a mounting hole is provided on the table of the trolley 1, and the receiving hopper 9 is arranged in the mounting hole;

[0036] The guide rail mechanism includes at least one guide rail 8, and the guide rail 8 includes a vertical rail and a curved rail 801 connected to each other. The vertical rail is vertically installed on the side of the trolley 1, and the curved rail 801 is higher than the table of the trolley 1, and its end points to the receiving hopper 9. The iron barrel bracket 7 is slidably installed on the guide rail 8, and the iron barrel bracket 7 is used to carry the iron barrel containing the alloy;

[0037] The first end of the boom linkage mechanism is hinged to the table top of the trolley 1, and the other end thereof is hinged to the iron barrel bracket 7; the first end of the telescopic drive member is hinged to the trolley 1, and the other end thereof is hinged to the boom linkage mechanism; the telescopic drive member is used to drive the boom linkage mechanism to pull the iron barrel bracket 7 to slide along the guide rail 8.

[0038] In this embodiment, when sampling or taking materials from the precious metal alloy in the iron barrel, an empty barrel is first placed on the trolley 1 below the receiving hopper 9, and then the iron barrel is moved to the iron barrel bracket 7, and then the hydraulic cylinder 10 is started. The hydraulic cylinder 10 extends to drive the boom linkage mechanism to pull the iron barrel bracket 7 to move upward along the guide rail 8. When the iron barrel bracket 7 moves to the arc rail 801, the iron barrel on the iron barrel bracket 7 gradually tilts, thereby pouring the precious metal alloy in the iron barrel into the receiving hopper 9.

[0039] In this way, the precious metal alloy in the iron barrel can be poured out simply and quickly, without the need for an overhead crane or the cooperation of multiple people. It has low labor intensity and a high safety factor, freeing up the overhead crane and other human resources, and even if the overhead crane is busy or fails, it will not affect the sampling or material collection work.

[0040] In this embodiment, if Figure 1 As shown, the boom linkage mechanism includes a connecting rod 3, a boom 4, an adapter plate 5 and a pull rod 6 connected in sequence. Two hinge seats 2 are fixedly installed on the table of the trolley 1. A first pin is rotatably installed between the two hinge seats 2. The end of the connecting rod 3 away from the boom 4 is fixedly connected to the first pin. The angle formed between the boom 4 and the connecting rod 3 is an obtuse angle. A cavity is provided in the trolley 1. The bottom end of the hydraulic cylinder 10 is hinged to the mounting seat on the bottom wall of the cavity, and the other end is hinged to the second pin on the end of the connecting rod 3 close to the boom 4. An adapter plate 5 is connected to the end of the boom 4 away from the connecting rod 3. The adapter plate 5 has a first end and a second end. The first end of the adapter plate 5 is fixedly connected to the end of the boom 4 away from the connecting rod 3. The second end of the adapter plate 5 points to the ground. The first end of the pull rod 6 is hinged to the second end of the adapter plate 5 through a third pin. The second end of the pull rod 6 is hinged to the iron barrel bracket 7.

[0041] In this way, when taking samples, the worker places the iron barrel containing the precious metal alloy on the iron barrel bracket 7, and then starts the hydraulic cylinder 10. The hydraulic cylinder 10 extends to push the connecting rod 3 to rotate clockwise around the first pin shaft. Driven by the connecting rod 3, the pull rod 6 pulls the iron barrel bracket 7 to slide upward along the guide rail 8 until the iron barrel bracket 7 moves to the arc rail 801. The iron barrel on the iron barrel bracket 7 gradually tilts, thereby pouring the precious metal alloy in the iron barrel into the receiving hopper 9.

[0042] As a specific embodiment, Figure 2As shown, there are two booms 4, adapter plates 5 and tie rods 6, and the booms 4, adapter plates 5 and tie rods 6 correspond to each other. The first ends of the two booms 4 are connected to one end of the connecting rod 3 at the same time, and an adapter plate 5 is fixedly installed on the second ends of the two booms 4, and a connecting rod 501 is fixedly installed between the two adapter plates 5, and a tripod structure is formed between the connecting rod 501 and the two booms 4. The first ends of the two tie rods 6 are respectively hinged to the second ends of the two adapter plates 5 through the third pin shaft, and the second ends of the two tie rods 6 are respectively hinged to the two sides of the iron barrel bracket 7 through the fourth pin shaft 11.

[0043] It should be clear that the tripod structure formed between the connecting rod 501 and the two booms 4 can greatly improve the structural strength of the boom linkage mechanism, so that it can stably lift a heavier iron barrel filled with alloy, and two pull rods 6 are used to connect the iron barrel bracket 7 so that the iron barrel bracket 7 can be pulled more stably.

[0044] In this embodiment, the guide rail mechanism includes two guide rails 8, which are vertically fixed on the same side of the trolley 1, and the iron barrel bracket 7 is slidably installed between the two guide rails 8. This arrangement ensures the stability of the iron barrel bracket 7 when sliding on the guide rails 8, and effectively prevents the two from being separated.

[0045] It should be noted that there are various ways of sliding connection between the guide rail 8 and the drum bracket 7. For example, a slider is slidably installed on the guide rail 8, and then the two sides of the drum bracket 7 are respectively connected to the sliding fixed on the two guide rails 8. For another example, multiple rollers are installed on the sides of the drum bracket 7, and multiple roller grooves adapted to the rollers are opened on the guide rail 8. The rollers on both sides of the drum bracket 7 are respectively embedded in the roller grooves on the two guide rails 8 and can slide along the roller grooves. I will not list them one by one here, as long as the drum bracket 7 can slide along the guide rail 8.

[0046] In order to prevent the iron barrel bracket 7 from being separated from the arc-shaped rail 801 when the iron barrel bracket 7 moves to the top end of the arc-shaped rail 801 of the guide rail 8, a stopper is fixed at the top end of the arc-shaped rail 801 to block the iron barrel bracket 7.

[0047] As a preferred embodiment, in order to ensure the flexibility of the alloy sampling and pouring device, rollers 101 are installed at the four corners of the bottom of the trolley 1. It should be clear that if Figure 1 As shown, the two rollers 101 on the left side of the trolley 1 are metal wheels, and the two rollers 101 on the left side are double wheel pairs. The double wheel pair consists of two wheels, which can be coaxial or can rotate independently but synchronously. The double wheel pair is a metal wheel. The two rollers 101 on the right side of the trolley 1 are universal wheels.

[0048] It should be noted that when lifting the iron drum, the weight of the entire drum of alloy is mainly supported by the front wheels, that is, Figure 1 The roller 101 on the left side of the small and medium-sized vehicle 1 is therefore set as a double wheel pair to improve stability and load-bearing capacity. Moreover, the metal wheel will not be easily embedded with metal iron filings or hard particles like the polyurethane rubber wheel, and has a stronger load-bearing capacity, adapts to the working environment, and is durable.

[0049] In this embodiment, if Figure 3 As shown, the iron barrel bracket 7 includes two side plates 701, two side rods 703, a connecting bottom plate 702, a crossbeam 704, an arc seat 705, a plurality of ear plates 706 and at least one barrel mouth clamp. The two side rods 703 are respectively fixed to the bottom of the two side plates 701, the connecting bottom plate 702 is fixed between the two side rods 703, the crossbeam 704 is fixed between the sides of the two side plates 701 close to the top thereof, the arc seat 705 is welded to the crossbeam 704, and an arc surface for fitting with the iron barrel is formed on the arc seat 705. A plurality of ear plates 706 for blocking the barrel mouth of the iron barrel are welded on the arc surface, and the ear plates 706 are used to block the iron barrel when the iron barrel is in a tilted state to prevent the iron barrel from falling from the iron barrel bracket 7. The barrel mouth clamp is fixedly mounted on the arc seat 705 (not shown in the figure).

[0050] It should be noted that, in this embodiment, an arc-shaped groove is provided on the top surface of the connecting bottom plate 702, and the arc-shaped groove is used to fit with the side surface of the iron barrel.

[0051] In this embodiment, the barrel mouth clamp is as follows Figure 5 and Figure 6 As shown, it includes a chain 14, a connecting ring 15, a main hook 12 and a locking hook 13; wherein one end of the chain 14 is welded to the top surface of the arc seat 705, and the other end thereof is hinged to the first end of the connecting ring 15 through a hook ring pin 16. The main hook 12 includes an arc hook 121 and an L-shaped hook 122 connected to each other, the left end of the arc hook 121 is formed with a first hook tip 123, and the other end thereof is connected to the top end of the L-shaped hook 122, and the end of the L-shaped hook 122 away from the arc hook 121 is formed with an abutting end 124, the abutting end 124 faces the first hook tip 123, and the abutting end 124 is lower than the first hook tip 123.

[0052] A semi-enclosed locking cavity is formed inside the arc-shaped hook 121, and the horizontal distance between the abutment end 124 and the first hook tip 123 is greater than the wall thickness of the iron barrel, so that the barrel mouth of the iron barrel can extend into the locking cavity. A mounting hole for inserting the locking hook 13 is provided on the main hook 12, and the mounting hole is opened from the top of the main hook 12 to the bottom thereof.

[0053] Furthermore, the locking hook 13 includes a handle 132 and a hook head 131 connected to each other. The hook head 131 is in a curved hook shape. A first mounting hole is provided at one end of the handle 132 close to the hook head 131, and a second mounting hole connected to the mounting hole is provided on the arc-shaped hook 121. The entire hook head 131 of the locking hook 13 and one end of the handle 132 close to the hook head 131 extend into the mounting hole of the main hook 12, and the first mounting hole on the locking hook 13 is aligned with the second mounting hole on the arc-shaped hook 121.

[0054] Furthermore, the locking hook 13 and the arc-shaped hook 121 are hingedly connected through a hook pin 17 and a return spring 18. Specifically, a bushing is provided in the center hole of the return spring 18, and the return spring 18 is sleeved on the hook pin 17 through the bushing, and the hook pin 17 is installed in the first mounting hole and the second mounting hole.

[0055] Furthermore, a second hook tip 133 is formed at one end of the hook head 131 away from the handle 132. The second hook tip 133 extends into the locking cavity, or in other words, at a position perpendicular to the locking cavity. Figure 6 In the paper direction, the projection of the second hook tip 133 falls into the locking cavity. In addition, the second end of the connecting ring 15 is connected to the handle 132, and the connecting ring 15 plays the role of a connecting piece.

[0056] In this embodiment, when using the alloy sampling and pouring device, the trolley 1 is first pushed close to the iron barrel so that the side of the iron barrel fits on the inner wall of the arc-shaped groove connected to the bottom plate 702, and then the hydraulic cylinder 10 is controlled to shorten a certain length to pull the iron barrel bracket 7 down to a certain height, and then the barrel mouth clamp will also drop to a certain height. During the lowering process of the barrel mouth clamp, Figure 5 As shown, the abutment end 124 is attached to the outer wall of the iron barrel, and the barrel mouth of the iron barrel extends into the locking cavity of the arc hook 121, and at this time, the first hook tip 123 of the arc hook 121 is attached to the inner wall of the barrel mouth, and the second hook tip 133 of the locking hook 13 is located outside the barrel mouth. Then the worker can manually push the handle 132 clockwise so that the second hook tip 133 of the locking hook 13 hooks the ring edge of the outer side of the barrel mouth of the iron barrel. Then the hydraulic cylinder 10 extends a certain length to pull the iron barrel bracket 7 up. Since the top of the chain 14 is welded to the arc seat 705, the chain 14 will pull the handle 132, and the handle 132 rotates clockwise around the axis of the hook pin 17, and the second hook tip 133 of the locking hook 13 rotates toward the first hook tip 123 to cooperate with the first hook tip 123 to clamp the barrel mouth. Moreover, as the iron barrel is gradually pulled up, the greater the pulling force on the locking hook 13 is, the greater the pressure exerted by the second hook tip 133 of the locking hook 13 on the outer wall of the barrel mouth is, so the barrel mouth can be firmly clamped.

[0057] It should be noted that if Figure 5As shown, the outer wall of the barrel mouth of the iron barrel is generally provided with a ring edge or a convex edge. When the barrel mouth clamp clamps the barrel mouth, the second hook tip 133 of the locking hook 13 will hook the ring edge on the outer side of the barrel mouth of the iron barrel, so that the gravity of the iron barrel will act on the second hook tip 133 of the locking hook 13.

[0058] After the material is taken, the iron barrel is placed on the ground and the handle 132 is in a stress-free state. At this time, the handle 132 can be rotated counterclockwise by a certain angle to disengage the second hook tip 133 of the locking hook 13 from the outer wall of the barrel mouth, thereby disengaging the barrel mouth clamp from the iron barrel.

[0059] The barrel mouth clamp of the embodiment can firmly clamp the barrel mouth of the iron barrel to ensure that the iron barrel will not fall off when pouring materials, thereby ensuring the safety of the equipment. The chain 14, locking hook 13 and main hook 12 of the barrel mouth clamp are all made of alloy, with high strength and long service life.

[0060] It should be noted that the installation position and the number of the barrel mouth clamp are not specifically limited, and the barrel mouth clamp can be installed on the arc surface of the arc seat 705 or on the side of the arc seat 705. Of course, it can also be installed on the crossbeam 704 of the iron barrel bracket 7 instead of the arc seat 705.

[0061] It should be noted that when a worker manually rotates the locking hook 13, he usually needs to hold the main hook 12 with one hand and hold the handle 132 with the other hand to rotate the handle 132 so that the second hook tip 133 on the locking hook 13 can be moved closer to or away from the first hook tip 123. This is laborious to use.

[0062] To solve this problem, Figure 7 As shown, a booster rod 125 is integrally formed or welded on the side of the arc-shaped hook 121 of the main hook 12, and the booster rod 125 is located on the side where the first hook tip 123 is located, and the booster rod 125 is tilted. The angle formed between the extension line of the length direction of the booster rod 125 and the handle 132 is an obtuse angle.

[0063] Thus, when rotating the locking hook 13 to clamp or release the mouth of the iron barrel, the worker holds the handle 132 and the booster rod 125 with one hand, and then presses the handle 132, so that the lower surface of the handle 132 is against the booster rod 125, and the top of the booster rod 125 is used as a fulcrum, so that the handle 132 can be pried more easily. This makes it easier to use the barrel mouth clamp, and it is easier to rotate the locking hook 13 to clamp or release the mouth of the iron barrel.

[0064] As an optional embodiment, a fastener is installed on the arc surface of the arc seat 705, and the fastener is used to replace the above-mentioned barrel mouth clamp. Figure 4As shown, the fastener includes a screw, a fastening plate 707 and at least one nut 708. A threaded hole is provided on the arc surface of the arc seat 705 along its radial direction, and the screw is threadedly connected in the threaded hole. The fastener is a fastening plate 707, and a round hole is provided on the fastening plate 707.

[0065] In this way, when taking materials, the alloy sampling and pouring device can be directly moved to the vicinity of the iron barrel, and the arc groove of the connecting bottom plate 702 is fitted to the iron barrel, and the arc surface of the arc seat 705 is also fitted to the iron barrel. Next, the fastening plate 707 is inserted into the screw rod, and the lower end of the fastening plate 707 is extended into the interior of the iron barrel. Finally, the nut 708 is screwed on the end of the screw rod and tightened. Under the action of the nut 708, the fastening plate 707 is tightly pressed against the barrel mouth of the iron barrel to fix the iron barrel, so as to achieve the following effect. Figure 3 Finally, the hydraulic cylinder 10 is started, and the hydraulic cylinder 10 is extended to drive the boom linkage mechanism to pull the iron barrel bracket 7 to move upward along the guide rail 8. When the iron barrel bracket 7 moves to the arc rail 801, the iron barrel on the iron barrel bracket 7 gradually tilts, thereby pouring the precious metal alloy in the iron barrel into the receiving hopper 9.

[0066] Preferably, the fastening plate 707 is an arc-shaped plate that matches the iron barrel. Of course, the fastening plate 707 can also be set to a rectangular plate or other shapes.

[0067] In this embodiment, if Figure 1 As shown, a mounting hole is opened on the table top of the trolley 1, and the receiving hopper 9 is arranged in the mounting hole, and the top of the receiving hopper 9 is hinged to the table top of the trolley 1 through a hinge, so that the receiving hopper 9 can be easily lifted when needed.

[0068] Exemplarily, the receiving hopper 9 is a square hopper. Of course, the receiving hopper 9 can also be configured as other types of hoppers.

[0069] It should be noted that a receiving bucket for receiving materials is placed on the chassis of the trolley 1 , and the receiving bucket needs to be placed directly below the receiving hopper 9 to receive the precious metal alloy that falls from the discharge port 901 of the receiving hopper 9 .

[0070] Since the receiving barrels are divided into two types, large barrels and small barrels, when a large-sized receiving barrel is used to receive the material, since the height difference between the barrel mouth of the large receiving barrel and the discharge port 901 of the receiving hopper 9 is small, the alloy splashing and dust will not be caused when receiving the material. When a small-sized receiving barrel is used to receive the material, since the height difference between the barrel mouth of the small-sized receiving barrel and the discharge port 901 of the receiving hopper 9 is large, the alloy splashing and dust will be caused. In order to solve this technical problem, a guide cylinder is equipped, which is funnel-shaped. The bottom opening diameter of the funnel-shaped guide cylinder is smaller than the right angle of the discharge port 901 of the receiving hopper 9. When installing the guide cylinder, it is only necessary to insert the guide cylinder into the receiving hopper 9 from the top of the receiving hopper 9, and the bottom of the guide cylinder passes through the discharge port 901 of the receiving hopper 9, and the outer side surface of the top is attached to the inner side surface of the receiving hopper 9. In this way, the height difference between the small-sized material receiving barrel and the material receiving hopper 9 can be compensated, thereby avoiding the problem of alloy splashing and dusting caused by the excessive height difference between the small-sized material receiving barrel and the material receiving hopper 9.

[0071] In addition, it should be clear that since the receiving hopper 9 is hingedly mounted on the surface of the trolley 1, when the space for placing a large-sized receiving bucket in the receiving area is limited, the receiving hopper 9 is lifted and the height of the receiving hopper 9 is appropriately raised, and then the large-sized receiving bucket is placed in the space below the receiving hopper 9.

[0072] It should be noted that the alloy sampling and pouring device is also equipped with a remote controller and a control module. A hydraulic system is installed inside the trolley 1, and the hydraulic system includes a hydraulic cylinder 10, a hydraulic pump, an oil tank, a solenoid valve, a pressure valve, and a receiver. The hydraulic pump is used to extract and pressurize the hydraulic oil from the oil tank and transport it to the hydraulic cylinder 10 through a pipeline. The solenoid valve is located between the hydraulic pump and the hydraulic cylinder 10, and it controls the path of the hydraulic oil flowing to the hydraulic cylinder 10, thereby controlling the extension and contraction of the hydraulic cylinder 10.

[0073] Among them, the receiver is installed in the control box of the hydraulic system, which receives the signal from the remote control and converts it into an electrical signal.

[0074] The commands from the remote control are transmitted to the receiver of the hydraulic system via wireless signals or wired connections. The remote control can be wireless, using radio frequency, Bluetooth or other wireless technologies, or wired, such as via a cable connection.

[0075] The receiver sends the electrical signal to the control module. The control module can be a PLC (Programmable Logic Controller) or other type of controller, which controls the solenoid valves in the hydraulic system based on the received signal.

[0076] The solenoid valve is a key component in the hydraulic system, which opens or closes the flow path of the hydraulic oil according to the command of the control module. The solenoid valve can be a proportional valve for precise control of oil flow, or a switching valve for simple on / off control.

[0077] In addition, a power supply is installed in the trolley 1, and the power supply is four 12V, 60ah lead-acid batteries, which supply power to various electrical components. Even if the factory is powered off, it will not affect the normal use of the alloy sampling and pouring device.

[0078] It should be noted that the alloy in the iron barrel has a particle size of 30mm to 60mm, a single piece weighs 0.5-2 kg, and has an irregular shape. Directly pouring the alloy into the receiving hopper 9 will form pits and burrs on the inner surface of the receiving hopper 9. To solve this technical problem, in this embodiment, a rubber skin with moderate thickness and softness is cut and formed according to the receiving hopper 9 model, and then naturally fits on the inner surface of the receiving hopper 9, which can avoid pits, burrs and noise caused by hard contact between the alloy and the hopper steel plate.

[0079] In this embodiment, considering that when the iron bucket is taken out, the iron bucket is located at the front end of the trolley 1 (i.e. Figure 1 The left side of the trolley 1 will cause the front end of the trolley 1 to be too heavy and the rear end to be too light, thus causing the trolley 1 to tilt. Therefore, the two wheels on the front side of the trolley 1 can be moved forward, and the rear end can be appropriately weighted, such as placing a weight block in the cavity of the trolley 1, which can effectively prevent the trolley 1 from tilting due to excessive weight.

[0080] As an optional embodiment, a handle 102 is installed at the rear end of the trolley 1 to facilitate pushing the trolley 1.

[0081] In this embodiment, a power switch and a charging port are installed on the trolley 1, and the power switch and the charging port are respectively connected to the above-mentioned power wires. The power switch is used to control the power switch, and the charging port is used to charge the power supply.

[0082] When using this alloy sampling and pouring device to take materials, it is generally divided into the following steps:

[0083] Step 1: prepare a suitable empty bucket as a material receiving bucket, and then place the material receiving bucket in the space below the material receiving hopper 9.

[0084] Step 2: Push the trolley 1 to the front of the iron barrel to be sampled, and then use the barrel mouth clamp or the above-mentioned fasteners to fix the barrel mouth.

[0085] Step 3: Turn on the power switch and press the up button on the remote control to automatically pour the material. You can release the button or press the down button at any time. The sample can be taken from the iron bucket above or from the receiving bucket below.

[0086] Step 4: After sampling, open the trolley 1, put down the original iron barrel, remove the receiving barrel and place it in a suitable position.

[0087] Step 5: Complete all sampling operations in a cycle, and finally turn off the power switch to use fragmented time to charge the battery.

[0088] In this way, one person can operate the sampling, which changes the previous situation that requires the collaboration of 3 to 4 people or even the cooperation of an overhead crane, improves work efficiency, reduces labor intensity and danger, and does not require manual load-bearing and lifting of buckets, freeing up the overhead crane and other human resources. Even if there is a power outage, the overhead crane is busy or a malfunction occurs, the sampling work will not be affected.

[0089] In addition, the alloy sampling and pouring device can not only be used for quality inspection sampling and automatic pouring of production ingredients, but also play a carrying function and be used for the storage position adjustment of barreled alloys. The overall appearance of this alloy sampling and pouring device is compact, occupying an area of ​​0.55m 3 , it can meet the needs of transporting, lifting, turning and unloading iron drums with a diameter of 300mm-420mm, a height of 300mm~700mm and a weight of ≤300kg.
