DETAILED DESCRIPTION

[0018] The specific embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0019] In the description of the present disclosure, it is necessary to understand that the terms "upper", "lower", etc., indicating orientation or positional relationship, are defined based on the drawing directions shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, and a specific orientation structure and operation, and therefore cannot be understood as a limitation on the present disclosure.

[0020] In the present disclosure, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element, and do not have order and importance. In addition, in the description with reference to the drawings, the same number in different drawings represents the same element.

[0021] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0022] As mentioned above, materials often pile up during the transfer process in the chute. Once the chute is blocked, the materials will be scattered and the cleaning work will be labor-intensive. In serious cases, it will cause equipment failure or even stop production, resulting in loss of economic benefits. In addition, general pile detection devices are easy to damage, cause wrong signal action, and are difficult to adjust the sensitivity.

[0023] In view of this, if Figures 1 to 6As shown, the present application provides a feeding device, including a feeding chute 20 and a detection device 10, the detection device 10 includes a pressure piece 11, a pressure sensor 12 and a support piece 13, the support piece 13 is suitable for being installed on a fixing piece fixed to the ground, the pressure sensor 12 is installed on the pressure piece 11 and / or the support piece 13, the feeding chute 20 includes a feeding port 21 and a discharging port 22, the pressure piece 11 is fixedly installed on the outer side wall of the feeding chute 20, and the pressure sensor 12 is used to detect the pressure applied by the pressure piece 11 to the support piece 13. By arranging the pressure piece 11 on the feeding chute 20 and the pressure sensor 12 on the support piece 13, the pressure applied by the pressure piece 11 to the support piece 13 is detected by the pressure sensor 12, so as to indirectly detect the amount of the material 120 inside the feeding chute 20, so as to judge the accumulation of the material 120 inside the feeding chute 20, thereby reducing the risk of the accumulation of the material 120 causing the material 120 to fall or cause equipment failure.

[0024] In the present disclosure, a fixing part refers to a fixing part installed on a foundation surface or a fixed wall. As long as the fixing part and the foundation surface are relatively stationary, for example, the fixing part can be a factory building structure. The support part 13 is installed on the fixing part, that is, the support part 13 is fixed relative to the foundation surface. Then, the support part 13 can support the pressure sensor 12 and / or the feed chute 20.

[0025] In some embodiments, the pressure sensor 12 can be installed on the support member 13 or the pressure member 11, and the feed chute 20 can be crimped to the pressure sensor 12 through the pressure member 11, that is, the support frame 131 supports the pressure sensor 12, the pressure member 11, the feed chute 20 and the internal material 120. The preset pressure value detected by the pressure sensor 12 includes the weight of the pressure member 11, the feed chute 20 and the internal material 120. By comparing the real-time output value of the pressure sensor 12 with the output value of the pressure sensor 12 during normal operation of the feeding equipment 100, it is possible to determine whether the current feed chute 20 is overloaded or underloaded.

[0026] In some embodiments, the pressure sensor 12 can be installed on the support member 13 or the pressure member 11, and the feed port 21 of the feed chute 20 can be hung on the fixing member with an elastic component, and the fixing member is relatively fixed to the foundation surface. When the feed chute 20 is empty or a small amount of material 120 is running, the pressure sensor 12 is installed on one of the support member 13 and the pressure member 11, and the detection head of the pressure sensor 12 may not contact the other. When the feed chute 20 is empty and running normally or overloaded, the detection head of the pressure sensor 12 is crimped with the other one. The output value of the pressure sensor 12 can be a preset pressure value for normal transportation of the material 120 or a preset pressure value for overload of the material 120. By comparing the output value of the pressure sensor 12 with the preset pressure value output by the pressure sensor 12 when the feeding equipment 100 is normally loaded, it can be determined whether the current feed chute 20 is overloaded or underloaded.

[0027] The pressure sensor 12 is a common pressure sensor.

[0028] In some embodiments, the number of pressure sensors 12 can be two or three, so that the function of accurately detecting pressure can be achieved by using a three-point or two-point lever principle.

[0029] In the present disclosure, since the pressure sensor 12 is arranged on the outside of the feed chute 20 and does not directly contact the material 120, the advantage of not contacting the material 120 for detection avoids wear of the detection device 10 and damage to the device. Therefore, the device is not easy to damage and has high accuracy. By judging the condition of the material 120 inside the feed chute 20 by the overall weight, the problem of the particle size of the material 120 affecting the judgment of the detection device 10 can be reduced, thereby solving the problems of easy damage, erroneous signal action, and low sensitivity of the general stockpile detection device 10.

[0030] In this disclosure, Figure 1 and Figure 3 As shown, in order to facilitate feeding at the feed port 21, the feeding device 100 may further include a feeding chute 30, and the feed port 21 of the feeding chute 20 is connected to the lower end of the feeding chute 30 through a first sealing software 40. That is, the feeding chute 30 is provided at the upper end of the feeding chute 20 for feeding, and the first sealing software 40 is provided between the two to connect, and the function of the first sealing software 40 is to seal the gap between the two and connect the two.

[0031] In some embodiments, the upper end of the feed chute 30 is connected to a fixing member, which is relatively fixed to the ground. Since the first sealing software 40 is a non-rigid fixing member, that is, the above-mentioned fixation cannot fix the position of the feed chute 20, the pressure sensor 12 can still detect the force applied by the pressure member 11 to the support frame 131, thereby indirectly detecting the transportation status of the material 120 inside the feed chute 20.

[0032] In some embodiments, a first bolt 41 is used between the first sealing software 40 and the feed chute 30, and a second bolt 42 is used between the first sealing software 40 and the feeding chute 20. Specifically, the first connecting bolt includes a screw and a nut, one end of the connecting screw is vertically welded to the side wall of the feeding chute 30, and the other end is sequentially penetrated with the first sealing software 40, a washer and a nut, wherein the nut is locked in the connecting screw, the first sealing software 40 and the washer are pressed, and the first sealing software 40 is connected to the side wall of the feeding chute 30. The first bolt 41 is provided in plurality to ensure that the connection between the first sealing cushion and the feeding chute 30 is sealed as much as possible to reduce material spillage. Similarly, the second connecting bolt includes a screw and a nut, one end of the connecting screw is vertically welded to the side wall of the feeding chute 20, and the other end is sequentially penetrated with the first sealing software 40, a washer and a nut, wherein the nut is locked in the connecting screw, the first sealing software 40 and the washer are pressed, and the first sealing software 40 is connected to the side wall of the feeding chute 20. A plurality of second bolts 42 are provided to ensure that a seal is formed at the connection between the first sealing cushion and the material conveying chute 20 as much as possible to reduce material spillage.

[0033] The gasket can be made of iron sheet or other hard materials, and the first sealing software 40 can be made of ordinary commercial tarpaulin or other soft materials such as canvas.

[0034] In this disclosure, Figure 1 and Figure 4 As shown, in order to facilitate the discharge of the material 120, the feeding device 100 may further include a discharge chute 50, and the discharge port 22 of the feeding chute 20 is connected to the upper end of the discharge chute 50 through a second sealing software 60. That is, the discharge chute 50 is provided at the lower end of the feeding chute 20 for discharging, and the second sealing software 60 is provided between the two to seal the gap between the two and connect the two.

[0035] Among them, the second sealing software 60 can be an ordinary commercial tarpaulin or other soft materials such as canvas. A third bolt 61 is used between the second sealing software 60 and the feed chute 20, and a fourth bolt 62 is used to connect the second sealing software 60 and the feed chute 20. The specific connection method is the same as the connection method of the first sealing software 40 mentioned above, which will not be discussed here.

[0036] In some embodiments, the discharge chute 50 can be fixedly connected to the material transport structure at the lower end (such as a conveyor 110), wherein, since the second sealing software 60 is a non-rigid fixing part, that is, the above-mentioned fixation cannot fix the position of the feed chute 20, the pressure sensor 12 can still detect the force applied by the pressure member 11 to the support frame 131, thereby indirectly detecting the transportation status of the material 120 inside the feed chute 20.

[0037] In this disclosure, Figure 4 As shown, in order to prevent the material 120 from scattering when being discharged, the feeding equipment 100 may also include a material guide trough 70, the lower end of the discharge chute 50 is connected to the upper end of the material guide trough 70, and the lower end of the material guide trough 70 is suitable for connecting to the conveyor 110 so that the material 120 in the material guide trough 70 can be transported to the conveyor 110.

[0038] In some embodiments, the guide trough 70 can be a trough body welded from steel plates, with closed sides and angle steel brackets welded to the frame of the conveyor 110. Except for the upper end of the guide trough 70 that is connected to the discharge chute 50, the rest of the parts are welded and sealed to prevent the material 120 from flying out. The lower end of the guide trough 70 is open to facilitate the material 120 to fall into the conveyor 110, thereby transporting the material 120. The function of the guide trough 70 is to guide the material 120 passing through the discharge chute 50, so that the material 120 can fall smoothly into the conveyor 110, prevent the material 120 from flying out, and reduce the material spillage.

[0039] In the present disclosure, the conveyor 110 may be a common commercial belt conveyor 110 installed below the material guide trough 70 , and may carry out the next step of transporting the material 120 of the discharge chute 50 .

[0040] In the present disclosure, the feeding device 100 also includes a control system and an alarm system. The alarm system and the pressure sensor 12 are both electrically connected to the control system. The control system is used to control the alarm system to operate according to a preset pressure value detected by the pressure sensor 12 .

[0041] In this disclosure, Figure 5 and Figure 6 As shown, in order to ensure the accuracy of the value detected by the detection device 10 , a plurality of detection devices 10 are provided, and the plurality of detection devices 10 are arranged around the circumference of the conveying chute 20 , wherein at least two detection devices 10 are provided on opposite sides of the conveying chute 20 .

[0042] In the present disclosure, the shape of the material conveying chute 20 is not limited as long as it has an inner cylinder capable of passing the material 120 .

[0043] For example, four detection devices 10 are provided, and the four detection devices 10 are evenly arranged around the circumference of the feeding chute 20, so that the weights of the four ends of the feeding chute 20 can be detected, realizing multi-point and multi-position detection, thereby improving the accuracy of detection.

[0044] In the present disclosure, in order to improve the bearing capacity of the support member 13, the support member 13 includes a support frame 131 and a support platform 132. The support frame 131 is set as a right-angled tripod. One right-angled side of the right-angled tripod is suitable for welding with a fixing member, and the other right-angled side of the right-angled tripod is connected to the support platform 132. The upper end of the support platform 132 has an upper surface 1321, and the pressure sensor 12 is arranged on the upper surface 1321. The pressure member 11 includes a contact platform 111. The side of the contact platform 111 is welded to the outer side wall of the feed chute 20. The lower surface 1111 of the contact platform 111 is suitable for crimping the pressure sensor 12. The lower surface 1111 of the contact platform 111 is arranged in parallel with the upper surface 1321 of the support platform 132. This setting can ensure the accuracy of the pressure sensor 12 detection and reduce the problem of inaccurate detection values ​​of the pressure sensor 12 due to the angle difference between the upper surface 1321 and the lower surface 1111.

[0045] In some embodiments, a reinforcement is connected to the upper end of the contact platform 111, and the reinforcement can be configured as a right-angled triangle, in which one right-angled side is welded to the outer wall of the feed chute 20, and the other right-angled side is connected to the contact platform 111, thereby enhancing the connection stability between the contact platform 111 and the outer wall of the feed chute 20.

[0046] In this disclosure, Figures 1 to 4 As shown, the feeding chute 20 comprises at least two barrel sections connected at an angle. Figures 1 to 4 In the embodiment of the present invention, the feeding chute 20 includes two barrel sections connected at an angle, and may also include three or more barrel sections. The feeding chute 20 of this structure is more prone to accumulation of materials 120.

[0047] In addition, the material conveying chute 20 may also be a material conveying chute with a discharge port structured as a closing structure.

[0048] According to another aspect of the present disclosure, a method for detecting piled material in a material conveying device 100 is provided, which is applied to the material conveying device 100 having a detection device 10, and the method comprises the following steps: Obtain the real-time pressure value applied by the pressure member 11 to the support member 13 when the feeding chute 20 is in the feeding state, According to the magnitude relationship between the real-time pressure value and the preset pressure value, it is determined whether the current state of the feeding chute 20 is an overload state, an underload state or a normal transportation state.

[0049] In the present disclosure, the preset pressure value includes a first preset pressure value and a second preset pressure value, and the first preset pressure value is smaller than the second preset pressure value.

[0050] The above-mentioned step of determining the current state of the feeding chute 20 according to the magnitude relationship between the real-time pressure value and the preset pressure value may include: If the real-time pressure value is less than the first preset pressure value, it is determined that the current state is an underload state. If the real-time pressure value is greater than the first preset pressure value and less than the second preset pressure value, it is determined that the current state is a normal transportation state. If the real-time pressure value is greater than the second preset pressure value, it is determined that the current state is an overload state.

[0051] This method also realizes the detection of system under-run.

[0052] The first preset pressure value and the second preset pressure value are determined by manual measurement.

[0053] In some embodiments, the preset pressure value may further include a third preset pressure value and a fourth preset pressure value, the third preset pressure value is less than the first preset pressure value, and the fourth preset pressure value is greater than the second preset pressure value. The above step of determining the current state of the feeding chute 20 according to the magnitude relationship between the real-time pressure value and the preset pressure value may further include: If the real-time pressure value is less than the third preset pressure value, or the real-time pressure value is greater than the fourth preset pressure value, it is determined that the current detection device 10 is in an abnormal state.

[0054] If the real-time pressure value is slightly less than the third preset pressure value, it is determined that the current detection device 10 is unloaded; If the real-time pressure value is slightly greater than the fourth preset pressure value, it is determined that the current detection device 10 is blocked.

[0055] The method for determining the first preset pressure value, the second preset pressure value, the third preset pressure value and the fourth preset pressure value may be: (1) Before commissioning or after maintenance, the pressure sensor 12 is powered on and the return power signal is tested to be normal. The preset pressure value of the pressure sensor 12 in the inactive state is read as M0. If the detection device 10 is set to multiple, the multiple preset pressure values ​​of the multiple pressure sensors 12 at this time are recorded as M01, M02, M03, M04, ... Mn, where M0 is the average value of the multiple preset pressure values.

[0056] (2) Feeding. During normal operation, the material 120 is evenly fed to the detection chute through the feed chute or the feed port 21. At this time, the material 120 evenly impacts the bottom and sides of the detection chute, forming a downward pressure on the detection chute, causing the detection result of the pressure sensor 12 to change. When the amount of feeding is stable, the data is basically stable. The preset pressure value of the pressure sensor 12 at a certain moment is taken as M1. If the detection device 10 is set to multiple, the multiple preset pressure values ​​of the multiple pressure sensors 12 at this time are recorded as M11, M12, M13, M14, ... Mn, where M1 is the average value of the multiple preset pressure values.

[0057] (3) During normal operation, large debris is artificially added, causing the detection chute to be blocked. At this time, there is a large amount of material 120 accumulated in the detection chute, and the pressure on the detection chute is much greater than the pressure on the detection chute caused by the impact of the material 120 in the normal operation state. At this time, the preset pressure value of the pressure sensor 12 is M2. If the detection device 10 is set to multiple, the multiple preset pressure values ​​of the multiple pressure sensors 12 at this time are recorded as M21, M22, M23, M24, ... Mn, where M2 is the average value of the multiple preset pressure values.

[0058] (4) Data analysis and calculation The first preset pressure value is M1, the second preset pressure value is M11+(M21-M11) / N, where N is greater than 1, the third preset pressure value is M0, and the fourth preset pressure value is M2.

[0059] During the actual detection process, the real-time pressure value of the pressure sensor 12 is detected, recorded, and analyzed at any time through the above control system (such as a data processing system).

[0060] 1. When the real-time pressure value is significantly less than the third preset pressure value M0, or when the real-time pressure value is significantly greater than the fourth preset pressure value M2, it is considered that the corresponding pressure sensor 12 is faulty, and the alarm system sends a fault alarm signal to remind inspection and replacement.

[0061] 2. When the real-time pressure value is less than the first preset pressure value M1, it is considered that the amount added is too small, that is, it is underloaded, and the alarm system sends an alarm signal to remind the operator to increase the feed.

[0062] 3. When the real-time pressure value is greater than the first preset pressure value M1 and less than the second preset pressure value M11+(M21-M11) / N (N>1), it is considered that the amount of material 120 added is reasonable, that is, it is in a normal transportation state.

[0063] 4. When the real-time pressure value is greater than the second preset pressure value M11+(M21-M11) / N (N>1), it is considered that the amount added is too large, that is, it is in an overload state, and there is a risk of blockage in the feeding chute 20. The alarm system sends a blockage pre-alarm signal to remind the operator to reduce the input of the material 120. The second preset pressure value M11+(M21-M11) / N (N>1) is manually set. In actual applications, the ratio can be adjusted according to actual conditions to adjust the alarm sensitivity. For example, the larger N is, the smaller the second preset pressure value is, and the higher the sensitivity is.

[0064] 5. When the real-time pressure value is slightly greater than the fourth preset pressure value M2, it is considered that the feeding chute 20 is blocked, that is, the feeding chute 20 is in a blocked state, and the alarm system sends out an alarm to remind the operator to perform maintenance.

[0065] 6. If the real-time pressure value is slightly less than the third preset pressure value M0, it is determined that the current detection device 10 is unloaded, and the alarm system alarms to remind the operator to feed.

[0066] Feeding equipment and method for detecting stacking of feeding equipment In view of the problems that the detection device 10 for stacking of the existing feeding chute 20 is easy to be damaged, frequently malfunctions, and the sensitivity is difficult to adjust, the feeding chute 30 and the feeding port 21, and the discharge port 22 and the discharge chute 50 are connected through a soft connection, so that the pressure sensor 12 is used to detect the pressure applied to the support member 13 of the feeding chute 20 section separately, and the amount of the material 120 inside is indirectly analyzed. The real-time pressure value of the pressure sensor 12 is compared and analyzed with the preset pressure value, so as to detect the stacking of the feeding chute 20. The device has the advantage of not contacting the material 120 for detection, avoiding the wear of the detection device 10. The pressure sensor 12 is used to match the data processing system, and the two functions of stacking pre-alarm and material 120 alarm are realized, and the detection sensitivity is adjustable. By matching the data processing system with the pressure sensor 12, the device also realizes the detection and alarm of the system under-quantity operation and the self-diagnosis and alarm function of the detection system hardware.
