[0020] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0021] As Figs. 1-3 shown, the utility model provides a container unloading system, including crane 1, at least one turnover unloading machine 2 and material transport equipment 3, crane 1 is located above the container transport equipment, is used to along the length direction of container transport equipment movement and transports the container on the container transport equipment to the turnover unloading machine 2, turnover unloading machine 2 is used to dump the material in the container to material transport equipment 3, material transport equipment 3 is set along the length direction of container transport equipment and is located at the discharge port of turnover unloading machine 2, is used to transport material.

[0022] Example, taking the train as the container transport equipment as an example, first, the train is parked to the left side below the gantry crane 1, then the gantry crane 1 and turnover unloading machine 2 parallel motion to the train tail, then the gantry crane 1 uses the spreader to hoist the first container of the train tail and moves to the right side turnover unloading machine 2, the turnover unloading machine 2 is fixed first to the container, then is turned over, to realize dumping the material in the container to material transport equipment 3, then material transport equipment 3 transports the dumped material to the material stacking position or use position, that is, realizes the unloading of a container, then the gantry crane 1 and turnover unloading machine 2 along the train movement to carry out subsequent container unloading.

[0023] It is worth noting that in this embodiment, the position of the container transport equipment, the turnover unloading machine 2 and the material transport equipment 3 is described, which is only used to describe the working principle and sequence, and is not limited thereto, that is, the container transport equipment can be located below the left side or the right side of the gantry crane 1, at this time, only the turnover unloading machine 2 and the material transport equipment 3 are set on the other side below the gantry crane 1.

[0024] The key to this invention lies in utilizing a mobile gantry crane 1 and a tipping unloader 2 to unload containers around the container transport equipment. Combined with material transport equipment 3, this shortens the container transport distance during unloading, improves unloading efficiency, and reduces the area required for unloading. As for how the gantry crane 1 moves and lifts the containers, any existing method can be used, and will not be elaborated upon here.

[0025] Since the tipping unloader 2 requires a certain amount of time to unload the materials from the container, the gantry crane 1 will be idle during this process. In order to further improve the unloading efficiency of the container, this utility model provides a preferred embodiment.

[0026] Preferred, such as Fig. 2 As shown, there are two tilting unloaders 2.

[0027] For example, two tippler unloaders 2 are arranged in a front-to-back configuration. The tippler unloader 2 in front is designated as loader number one, and the tippler unloader 2 in the rear is designated as loader number two. At the start of the unloading operation, the gantry crane 1 first loads container number one onto loader number one, which then tipples and unloads it. Simultaneously, the gantry crane 1 loads the second container onto loader number two, which then tipples and unloads it. By this time, loader number one has completed tipping and unloading container number one. The gantry crane 1 then lifts the empty container number one from loader number one onto the container transport equipment or a container yard. When needed, the third container is then picked up, and this process is repeated. This method fully utilizes the time spent by the tippler unloaders 2 tipping and unloading containers, further improving the unloading efficiency.

[0028] like Figs. 1-3 As shown, the tipping unloader 2 includes a fixed frame 201, a tipping frame 202, a container locking mechanism, a tipping mechanism, and a traveling mechanism; the tipping frame 202 is located on top of the fixed frame 201 and is used to accommodate containers; the container locking mechanism is located on the inner bottom surface of the tipping frame 202 and is used to lock the containers; the tipping mechanism is located at both ends of the tipping frame 202 and is used to drive the tipping frame 202 to rotate; the traveling mechanism is located on the fixed frame 201 and is used to drive the fixed frame 201 to move.

[0029] For example, when it is needed to unload the container, the turnover unloading machine 2 is first moved to below the gantry crane 1 by the walking mechanism, then the gantry crane 1 hoists the container on the container transport device to the turnover frame 202 of the turnover unloading machine 2, then the container locking mechanism on the inner bottom surface of the turnover frame 202 locks the container to prevent the container from falling off during the dumping process, then the turnover mechanism at both ends of the turnover frame 202 operates to dump the container, and during the dumping process, the materials in the container slide to the material transport device 3 below the turnover unloading machine 2, that is, the unloading of the container is completed.

[0030] It is worth noting that in this embodiment, only the relative position relationship and operation mode of the turnover frame 202, the container locking mechanism, the turnover mechanism and the walking mechanism are limited, but the specific structure, style and model thereof are not set, that is, the specific structure, style and model of the turnover frame 202, the container locking mechanism, the turnover mechanism and the walking mechanism can be arbitrarily set by the person skilled in the art according to the actual situation.

[0031] Since the materials loaded in the container are different, the turnover angle of the turnover frame 202 is different during the unloading of different materials, and the present application provides an optimal embodiment for this phenomenon.

[0032] Preferably, the turnover mechanism is a rotary motor.

[0033] For example, the rotary motor can better control the turnover angle of the turnover frame 202, and can control the turnover angle of the turnover frame 202 according to the type of the materials in the container, so as to realize fine control and further improve the unloading efficiency of the container.

[0034] Since the turnover unloading machine 2 needs to match the movement speed of the gantry crane 1 so as to be in the same straight line, so that the gantry crane 1 can better hoist the container to the turnover unloading machine 2, the present application provides an optimal embodiment.

[0035] Preferably, the walking mechanism is an electrically driven walking wheel.

[0036] For example, the electrically driven walking wheel can better control the movement speed of the turnover unloading machine 2, so that the movement of the turnover unloading machine 2 can match the gantry crane 1, so that the gantry crane 1 can better hoist the container to the turnover unloading machine 2.

[0037] More preferably, the turnover frame 202 is of a skeleton type structure.

[0038] For example, the skeleton type structure facilitates the staff to better observe whether the container is locked, and facilitates the detection and maintenance of the container locking mechanism in the subsequent use process.

[0039] Since the material in the container will be quickly poured out after the turnover mechanism drives the turnover frame 202 to rotate during the unloading process, and the material transportation device 3 has limited transportation efficiency, pouring a large amount of material onto the material transportation device 3 in a short time will cause material accumulation, and even material sliding, therefore, the utility model provides an optimal embodiment.

[0040] Preferably, as shown in the figure, the turnover unloading machine 2 further comprises: an unloading hopper 203 located below the turnover frame 202, used for containing material in a short time. Figs. 1-3

[0041] For example, after the turnover mechanism drives the turnover frame 202 to rotate, the material is poured from the container to the unloading hopper 203, and then the material is transported to the material transportation device 3 through the unloading hopper 203, so as to avoid pouring a large amount of material onto the material transportation device 3 in a short time.

[0042] It is worth noting that in this embodiment, only the position and working principle of the unloading hopper 203 are set, but the specific size, material, inclination angle, volume, etc. of the unloading hopper 203 are not limited, that is, the specific size, material, inclination angle, volume, etc. of the unloading hopper 203 can be arbitrarily set by the person skilled in the art according to the actual situation.

[0043] Since the turnover frame 202 only needs to rotate in one direction during the tilting process to complete the unloading, the relative position relationship between the turnover frame 202 and the unloading hopper 203 can be appropriately adjusted to ensure that the container material can completely fall into the unloading hopper 203, while reducing the volume of the unloading hopper 203 to prevent the unloading hopper 203 from being overfilled.

[0044] Preferably, as shown in the figure, the unloading hopper 203 is located below the turnover frame 202. Fig. 3

[0045] For example, taking the unloading hopper 203 rotating to the right for unloading as an example, when the turnover frame 202 rotates to the right, the container located in it also rotates to the right, and when the turnover frame 202 rotates to the horizontal with the ground, the edge of the container coincides with the center line of the unloading hopper 203, so as to realize the complete pouring of the container into the unloading hopper 203.

[0046] Since the unloading hopper 203 is a hollow structure, when there is a large amount of material in the unloading hopper 203, the flow rate of the material is relatively slow and stable, but when there is a small amount of material in the unloading hopper 203, the flow rate of the material will be fast and unstable, which will cause the material transportation device 3 to transport different amounts of material per unit time, which is not conducive to the stacking and use of the material, therefore, the utility model provides an optimal embodiment.

[0047] Preferably, as shown in the figure, the unloading hopper 203 is located below the turnover frame 202. Figs. 1-3 ​​As shown, the turnover unloading machine 2 further comprises a uniform feeding device located at the discharge port of the discharge hopper 203, which is used to uniformly feed the material onto the material conveying device 3.

[0048] For example, after the material flows out of the discharge hopper 203, the material falls on the uniform feeding device, and the uniform feeding device is used to feed the material onto the material conveying device 3 in a certain time and a certain dose, so as to ensure that the material conveying device 3 transports the material in a consistent dose in a unit time.

[0049] It is worth noting that in this embodiment, only the installation position and working principle of the uniform feeding device are limited, but the specific structure, size, etc. of the uniform feeding device are not set, that is, the specific structure, size, etc. of the uniform feeding device can be arbitrarily set by those skilled in the art.

[0050] More preferably, the uniform feeding device is a belt feeder.

[0051] Since the material will move rapidly in the air during the unloading process, dust is easy to be generated, the environment is damaged, and the workers' bodies are easy to be harmed. Therefore, an optimal embodiment is provided in the utility model.

[0052] Preferably, the turnover unloading machine 2 further comprises a dust removal device located at the periphery of the turnover frame 202, which is used to remove the dust generated during the dumping of the container material.

[0053] For example, after the turnover frame 202 is turned over, the material is dumped out of the container, and the dust removal device works during the dumping process to treat the dust generated during the dumping of the material.

[0054] It is worth noting that in this embodiment, only the installation position and working mode of the dust removal device are limited, but the specific structure, dust removal mode, etc. of the dust removal device are not limited, that is, the specific structure, dust removal mode, etc. of the dust removal device can be arbitrarily limited by those skilled in the art.

[0055] Specifically, the dust removal device is a water mist dust removal machine.

[0056] For example, the working principle of the water mist dust removal machine is to use the water mist released by the dust removal machine to adsorb the dust to prevent the dust from spreading, so as to achieve the removal of the dust.

[0057] Preferably, the material conveying device 3 is a belt conveyor.

[0058] For example, the belt conveyor can stably transport a certain dose of material to the end in a unit time, so as to facilitate the use of the material.

[0059] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
