Description

Automatic metering unloading loader

Technical Field

The utility model belongs to the technical field of mechanical equipment, and in particular relates to an automatic metering unloading and loading machine.

Background technique

Ceramic aggregate is a lightweight aggregate produced by foaming in a rotary kiln. It has a spherical shape, a smooth and hard surface, a honeycomb interior, and is characterized by low density, low thermal conductivity, and high strength. In the refractory industry, ceramsite is mainly used as an aggregate for thermal insulation refractory materials.

At present, when loading ceramsite, a measuring bucket (for example, 0.5 cubic meters/bucket) is used for loading and unloading, so as to complete the measurement of ceramsite. At present, manual counting is usually adopted, but when manual counting is performed, it is easy to have problems such as under-recording, over-recording or calculation errors.

The prior art discloses a bulk loading system for powder materials (publication number CN116620892A). The driver starts and stops loading by pressing a loading button. After loading starts, the main controller starts a sampling countdown. When the countdown ends, the main controller issues a sampling command, the sampler starts, and after running the set sampling time, sampling stops. At the same time, the loading count is increased by one. When the number of loaded vehicles reaches the sampling set number of vehicles, the controller sends an alarm signal, and the loading count is accumulated through programming.

The above technical solution counts by setting the sampling time, and the measured number is the loading number. However, if counting is performed by sampling time, it depends on the material falling speed and amount. It is very likely that the amount of material loaded will have a large error due to insufficient supply.

Utility Model Content

The utility model aims to provide an automatic metering unloading loader to solve the problem that the prior art counts by sampling time, which may cause a large difference in the amount of loaded materials due to insufficient supply.

In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: an automatic metering unloading and loading machine, comprising a bracket, a discharging unit, a metering unit and a counting unit, wherein the discharging unit is used to convey expanded clay to the metering unit, the metering unit comprises a control component and a quantitative component, the quantitative component comprises four groups of quantitative buckets and a rotating part, the four groups of quantitative buckets are respectively fixed on the circumference of the rotating part, the rotating part is rotatably connected to the bracket, the four groups of quantitative buckets can maintain balance when not loaded and are respectively located in the four directions of the upper, lower, left and right of the rotating part; the loading vehicle is located below the quantitative component; the control component is located on the left or right side of the quantitative component, the control component comprises a controller and a material measuring mechanism and a fixing mechanism connected to the controller, the material measuring mechanism is used to measure the amount of expanded clay in the quantitative bucket and send a signal to the controller; the fixing mechanism is used to fix or release the quantitative bucket close to it; the counting unit is fixed on the bracket and is located below the quantitative bucket being loaded, and the counting unit is used to measure the number of times the quantitative bucket passes through the metering unit.

Furthermore, a side of the metering hopper away from the rotating member is configured as an inclined structure, and a surface of an opening end of the metering hopper is larger than an area of a bottom portion.

Furthermore, the counting unit adopts an infrared induction counter.

Furthermore, the discharging unit includes a shuttle slot and a blocking component for blocking a discharging port of the shuttle slot, the blocking component is controlled by the controller, and the shuttle slot is fixed on a bracket.

Furthermore, the material measuring mechanism is installed on the discharging unit, and the material measuring mechanism adopts a photoelectric switch, and the distance between the photoelectric switch and the quantitative bucket is set according to the sensing distance of the photoelectric switch.

Furthermore, the fixing mechanism includes a fixing cylinder connected to the controller, a telescopic rod of the fixing cylinder is connected to a fixing plate, and the fixing cylinder fixes or releases the quantitative bucket by driving the fixing plate to move.

The working principle of this technical solution is that when loading is required, the vehicle is driven to the bottom of the quantitative component, and at this time, the telescopic rod of the fixed cylinder is extended, and the fixed plate presses the quantitative bucket tightly. Then the whole machine is started, the blocking component of the shuttle slot outlet is opened, and the ceramsite is transmitted to the quantitative bucket below that is pressed tightly through the shuttle slot. When the ceramsite material in the quantitative bucket reaches the control point of the photoelectric switch (that is, the accumulated ceramsite surface reaches the effective distance of the photoelectric switch sensing), the photoelectric switch sends a signal to the controller, and the controller immediately starts the blocking component, and the blocking component blocks the outlet of the shuttle slot. Then the fixed cylinder is started, and the telescopic rod of the fixed cylinder is retracted, driving the fixed plate away from the quantitative bucket. Since ceramsite is added to one quantitative bucket, the four quantitative buckets lose balance, and the quantitative bucket with ceramsite added turns downward until it turns to the bottom. The next empty quantitative bucket will come to the loading position. During the rotation of the quantitative bucket, it will pass through the infrared sensing counter, and the infrared sensing counter will count once after sensing it once. At the same time, when the photoelectric switch cannot sense the expanded clay, it will send a signal to the controller. The controller will start the telescopic rod of the fixed cylinder to extend, driving the fixed plate to re-fix the new quantitative bucket. Then the controller will open the blocking component, the discharge port of the shuttle slot will open, the expanded clay will fall into the quantitative bucket, and the quantitative bucket will be reloaded.

The beneficial effects of this technical solution are:

① This technical solution integrates automatic loading, unloading and counting, replacing manual loading and counting, reducing labor costs, and avoiding the problems of under-recording, over-recording and calculation errors caused by manual counting.

② This technical solution replaces the sampling time in the prior art with a photoelectric switch, which can perform quantification more accurately and avoid the problem of large errors caused by the falling speed and falling amount.

③ This technical solution sets the side of the metering bucket away from the rotating part as an inclined structure, which can make the ceramsite in the metering bucket fall out completely when the metering bucket reaches the bottom. If it is not set as an inclined structure, some ceramsite will remain in the metering bucket. After the next metering bucket is loaded, since the weight of the metering bucket is greater than the weight of the previous metering bucket, it will deflect and the ceramsite in the previous metering bucket will fall out completely. However, the ceramsite in the last metering bucket needs to be manually rotated to make the ceramsite fall out completely. Therefore, it is set as an inclined structure, and no manual operation is required.

The embodiment is basically as shown in Figure 1: an automatic metering unloading loader, including a bracket, a discharging unit, a metering unit and a counting unit.

The shuttle slot 4 is fixed on the bracket. The sealing component can use a solenoid valve or a combination of a cylinder (or a linear motor, etc.) and a baffle.

The metering unit includes a control component and a quantitative component. The quantitative component includes four groups of quantitative buckets 1 and a rotating member. The four groups of quantitative buckets 1 are respectively fixed on the circumference of the rotating member. The rotating member is rotatably connected to the bracket. The four groups of quantitative buckets 1 can maintain balance when not loaded and are respectively located in the four directions of the upper, lower, left and right of the rotating member; specifically, the rotating member includes a bearing 2 and a connecting block 3. The bearing 2 is rotatably connected to the bracket. The center of the connecting block 3 is circular and the outside is square. The center of the connecting block 3 is fixed to the bearing 2, and the four quantitative buckets 1 are fixed to the outside of the connecting block 3. The loading vehicle is located below the quantitative component; the control component is located on the left or right side of the quantitative component (the technical solution is on the left side). The side of the quantitative bucket 1 away from the rotating member is set to an inclined structure, and the surface of the open end of the quantitative bucket 1 is larger than the bottom area. The control component includes a controller and a material measuring mechanism and a fixing mechanism connected to the controller. The material measuring mechanism is used to measure the amount of ceramsite in the quantitative bucket and send a signal to the controller. The material measuring mechanism is installed on the discharging unit. The material measuring mechanism adopts a photoelectric switch 5. The distance between the photoelectric switch 5 and the quantitative bucket 1 is set according to the sensing distance of the photoelectric switch 5. The fixing mechanism is used to fix or loosen the metering bucket 1 close to it, and the fixing mechanism includes a fixing cylinder 6 connected to the controller, and the telescopic rod of the fixing cylinder 6 is connected to the fixing plate 7. The fixing cylinder 6 fixes or loosens the metering bucket 1 by driving the fixing plate 7 to move.

The counting unit is fixed on the bracket and is located below the metering bucket 1 being loaded. The counting unit is used to measure the number of times the metering bucket 1 passes through the metering unit. The counting unit adopts an infrared induction counter 8.

The specific implementation process is as follows:

When loading is required, the vehicle is driven to the bottom of the quantitative component, and at this time, the telescopic rod of the fixed cylinder 6 is extended, and the fixed plate 7 presses the quantitative bucket 1 tightly. Then the whole machine is started, and the blocking component of the discharge port of the shuttle slot 4 is opened, and the ceramsite is transmitted to the quantitative bucket 1 pressed below through the shuttle slot 4. When the ceramsite material in the quantitative bucket 1 reaches the control point of the photoelectric switch 5 (that is, the accumulated ceramsite surface reaches the effective distance sensed by the photoelectric switch 5), the photoelectric switch 5 sends a signal to the controller, and the controller immediately starts the blocking component, and the blocking component blocks the discharge port of the shuttle slot 4. Then the fixed cylinder 6 is started, and the telescopic rod of the fixed cylinder 6 is retracted, driving the fixed plate 7 away from the quantitative bucket 1. Since ceramsite is added to one quantitative bucket 1, the four quantitative buckets 1 lose balance, and the quantitative bucket 1 with ceramsite added turns downward until it turns to the bottom. The next empty quantitative bucket 1 will come to the loading position. During the rotation of the quantitative bucket 1, it will pass through the infrared sensing counter 8, and the infrared sensing counter 8 will count once after sensing once. At the same time, when the photoelectric switch 5 cannot sense the expanded clay, it will send a signal to the controller, which will start the telescopic rod of the fixed cylinder 6 to extend, driving the fixed plate 7 to re-fix the new quantitative bucket 1, and then the controller will open the blocking component, the discharge port of the shuttle slot 4 will open, the expanded clay will fall into the quantitative bucket 1, and the quantitative bucket 1 will be reloaded.

This technical solution integrates automatic loading, unloading and counting, replaces manual loading and counting, reduces labor costs, and can avoid the problems of under-recording, over-recording and calculation errors caused by manual counting.
