[0033] The following will further describe the present utility model in detail with reference to the accompanying drawings of the specification and specific embodiments.

[0034] As Figures 1 to 2As shown in the figure, this embodiment discloses a sample bucket transporter, which includes a vehicle head and a carriage part. The carriage part includes a cargo box 1. A conveying device 2 capable of moving forward and backward is installed on the bottom plate of the cargo box 1. A flip door device 3 is provided at the tail of the cargo box 1. The flip door device 3 is installed on the bottom plate of the cargo box 1 through a mounting frame. A conveying mechanism 4 is provided on the side of the door panel of the flip door device 3 facing the inside of the cargo box 1. After the flip door device 3 is flipped outwards towards the carriage part, it forms a docking with external equipment, so as to enable the sample buckets on the external equipment to be transported to the conveying device 2 through the conveying mechanism 4 for storage and then transported, or enable the sample buckets stored on the conveying device 2 to be transmitted to the external equipment through the conveying mechanism 4 on the flip door device 3. After the flip door device 3 is flipped inwards towards the inside of the cargo box 1, it closes the tail of the cargo box 1. It also includes a power supply battery assembly and an electric control assembly 5. The power supply battery assembly is used to supply power to the transporter and each component, and the electric control assembly 5 is used to control each component.

[0035] The transporter in this embodiment is powered by a battery assembly. During the driving process of the vehicle, the conveying device 2 is in a power-off state. When the transporter reaches the sampling point or the sample preparation point, the driver can supply power to the conveying device 2 through the power-on button. When the conveying device 2 has no action within the set time, the electric control assembly 5 automatically cuts off the power supply to the conveying device 2, which can effectively save power. Since the transporter is equipped with a battery assembly itself, when transporting sample buckets, there is no need to lay a power supply box at the sampling point and no need to plug in an external power supply, which greatly simplifies the docking process and reduces the cost of the equipment.

[0036] The sample bucket transporter in this embodiment is designed with a flip door device 3. The flip door device 3 can be flipped within the range of 0° to 90°. When the flip door device 3 is at 0°, the conveying mechanism 4 on the flip door device 3 can form a docking with external equipment to realize the operation of loading or unloading buckets. When the flip door device 3 is at 90°, the door panel of the flip door device 3 is flush with the tail of the cargo box 1 and acts as the tail door of the cargo box 1. The overall structure is simpler than that of a rolling shutter door and is not prone to failure, which greatly reduces the maintenance frequency and improves the work efficiency.

[0037] Such as Figure 3 And Figure 4As shown in the figure, in this embodiment, the flipping door device 3 further includes a flipping driving device 6 and a flipping connecting shaft assembly 7. The flipping driving device 6 includes a driving motor 61, a driving gear 62 and a driven gear 63. The driving gear 62 is connected to the motor shaft of the driving motor 61, and the driving gear 62 meshes with the driven gear 63. The driving motor 61 is used to drive the flipping door device 3 to flip between 0° and 90°. The flipping connecting shaft assembly 7 includes a bearing mounting seat 71, a first bearing 72 and a connecting shaft 73. One end of the connecting shaft 73 is mounted on the bearing mounting seat 71 through the first bearing 72, and the other end of the connecting shaft 73 is connected to the driven gear 63. The driving motor 61 drives the driving gear 62 to rotate, and the driving gear 62 drives the driven gear 63 to rotate, thereby driving the connecting shaft 73 to rotate to realize the flipping of the flipping door device 3.

[0038] In this embodiment, a position detection component 8 is further included. The position detection component 8 is used to detect the position information of the flipping door device 3. Further, in a preferred embodiment, a mounting plate mounted on the bearing mounting seat 71 is further included, and the position detection component 8 is arranged on the mounting plate.

[0039] In this embodiment, a buffer and a travel switch are further mounted on the flipping door device 3. The buffer is used to buffer the flipping process of the flipping door device 3, and the travel switch cuts off the power when the flipping door device 3 reaches the limit position.

[0040] In this embodiment, flipping side plates 9 are further arranged on both sides of the conveying mechanism 4, and the position of the sample bucket is restricted from both sides through the flipping side plates 9.

The rotating bucket blocking device 10 includes a rotating driving mechanism 101, a driving mounting seat 102, a rotating shaft 103, a blocking rod assembly 104, a rotating shaft support seat 105, a bearing seat 106 and a second bearing 107. The rotating driving mechanism 101 is mounted on the conveying device 2 through the driving mounting seat 102. The rotating shaft 103 is connected to the rotating driving mechanism 101 and is mounted on the rotating shaft support seat 105 through the second bearing 107 and the bearing seat 106. A plurality of blocking rod assemblies 104 are arranged on the rotating shaft 103. The blocking rod assemblies 104 rotate unidirectionally on the rotating shaft 103. When the blocking rod assemblies 104 are at 0°, that is, the blocking rod assemblies 104 are parallel to the horizontal plane, the adjacent blocking rods can prevent the sample bucket from tipping forward and backward. When the blocking rod assemblies 104 are at 90°, that is, the blocking rod assemblies 104 are perpendicular to the horizontal plane, the sample bucket can automatically move on the conveying device 2 to realize the operations of feeding the bucket and discharging the bucket.

[0042] In this embodiment, it further includes a barrier rod detection component 11, which is used to detect the position information of the barrier rod component 104. Further, in a preferred embodiment, there are two barrier rod detection components 11, which respectively detect the positions of the barrier rod component 104 at 0° and 90°.

[0043] As Figure 6 shown, in this embodiment, it further includes a tipping door positioning device 12, which includes a mounting rod 121, a buffer 122 and a travel switch 123. The two ends of the mounting rod 121 are respectively connected to the two side walls of the cargo box 1, and the two ends of the mounting rod 121 are installed on the left and right side pipes inside the cargo box 1. The buffer 122 and the travel switch 123 are arranged on the mounting rod 121. The buffer 122 is used to buffer the movement of the tipping door device 3, and the travel switch 123 is used to cut off the power when the tipping door device 3 flips to the limit position.

[0044] As Figure 7 shown, in this embodiment, the side wall of the cargo box 1 is provided with a double-leaf door mechanism 13, the top wall of the cargo box 1 is provided with a plurality of lifting lugs 14, and the outer wall of the cargo box 1 is provided with a control button 15 connected to the electric control component 5. When the driver of the transporter confirms that the transporter is in place, press the control button 15 to start the sample bucket docking process. The double-leaf door mechanism 13 is used for installation, debugging and maintenance, and the lifting lugs 14 are used for hoisting and transporting the cargo box 1.

[0045] As Figure 8 shown, in this embodiment, the electric control component 5 includes an electric control cabinet 51, and the electric control cabinet 51 is provided with a touch control screen 511 and an emergency stop button 512. The electric control component 5 is a control module for sample bucket transportation. The touch control screen 511 displays information such as system operation, debugging, and alarm, and the electric control cabinet 51 is installed on the bottom plate of the cargo box 1.

[0046] As Figure 9 shown, in this embodiment, the conveying device 2 is a roller conveying mechanism, which includes a driving component 21, rollers 22 and a chain 23. Adjacent rollers 22 transmit power through the chain 23. The driving component 21 is used to drive the chain 23 to rotate forward and backward to realize the feeding and discharging of the sample bucket. Baffles 24 are arranged on both sides of the roller conveying mechanism to limit the movement of the sample bucket. A guide bar 16 is arranged in the middle of the roller conveying mechanism to divide the roller conveying mechanism into two sample bucket conveying channels; a bucket blocking frame 17 is arranged at the other end of the roller conveying mechanism far from the inlet and outlet ends of the sample bucket to limit the sample bucket. In other embodiments, the conveying device 2 can also be a belt conveyor.

[0047] In this embodiment, a first detection component 18 is provided at the inlet and outlet ends of the roller conveyor mechanism close to the sample barrels. The first detection component 18 is used to detect whether the roller conveyor is full of sample barrels. When the first detection component 18 detects a signal, it indicates that the conveying device 2 is full of sample barrels, and the signal is fed back to the electric control component 5 to stop the operation of loading barrels. A second detection component 19 is provided at one end of the roller conveyor mechanism close to the barrel blocking rack 17. The second detection component 19 is used to detect whether there is a barrel entering the roller conveyor mechanism.

[0048] In this embodiment, an array of detection components (not shown in the figure) is also provided between the first detection component 18 and the second detection component 19 for accurately counting the number of sample barrels loaded on the vehicle.

[0049] In this embodiment, the conveying device 2 is powered by a power supply battery component. It should be noted that the power supply battery component can be an on-vehicle battery pack or an independent battery pack installed in the cargo box 1. When the cargo box 1 is provided with an independent battery pack, the cargo box 1 can be matched with different types of freight trucks (such as fuel freight trucks or electric freight trucks) without an external power supply. Each driving device such as the driving component 21, the driving motor 61, the rotary driving mechanism 101, etc. is driven by a 24V DC driving motor to ensure matching with the output voltage of the power supply battery component of the transfer vehicle.

[0050] Barrel loading process: After the driver drives the transfer vehicle into position, the power-on button is activated to supply power to the conveying device 2. The control button 15 is clicked, and the flipping door device 3 flips to 0° (at this time, the flipping door device 3 is parallel to the horizontal plane). The blocking rod component 104 rotates to be perpendicular to the horizontal plane. The conveying mechanism 4 and the conveying device 2 on the flipping door device 3 start to rotate forward for barrel loading. After the barrel loading is completed, the blocking rod component 104 rotates to be horizontal with the horizontal plane, and the flipping door mechanism flips to 90° (at this time, the flipping door device 3 is perpendicular to the horizontal plane), and the transfer vehicle transfers the sample barrels.

[0051] Barrel unloading process: After the driver drives the transfer vehicle into position, the power-on button is activated to supply power to the conveying device 2. The control button 15 is clicked, and the flipping door device 3 flips to 0° (at this time, the flipping door device 3 is parallel to the horizontal plane). The blocking rod component 104 rotates to be perpendicular to the horizontal plane. The conveying mechanism 4 and the conveying device 2 on the flipping door device 3 start to rotate in the reverse direction for barrel unloading. After the barrel unloading is completed, the blocking rod component 104 rotates to be horizontal with the horizontal plane, and the flipping door mechanism flips to 90° (at this time, the flipping door device 3 is perpendicular to the horizontal plane), and the transfer vehicle continues to transfer the next batch of sample barrels.
