Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-3 As shown, the utility model provides a technical solution:

[0026] A bulk material transport device for a clean area of ​​citric acid production, comprising:

[0027] A vehicle body 1, a guide plate 2 and a wheel cleaning assembly 3, wherein the interior of the vehicle body 1 is hollow, a feed port 4 is provided on the top of the vehicle body 1, a discharge port 5 is provided on one side of the vehicle body 1, the guide plate 2 is arranged inside the vehicle body 1, a wheel 6 is arranged at the bottom of the vehicle body 1, and the wheel cleaning assembly 3 is arranged at the bottom of the vehicle body 1, and is located on one side of the forward direction of the wheel 6 and is in contact with the wheel 6; the guide plate 2 includes a back guide plate 21, a bottom guide plate 22 and a middle guide plate 23, and all are arranged inclined, the inclination direction of the back guide plate 21 and the bottom guide plate 22 are consistent, and both are toward the discharge port 5, and the inclination direction of the middle guide plate 23 is opposite to the inclination direction of the bottom guide plate 22.

[0028] In this embodiment, a handle 7 is also included, which is arranged on the outer wall of the vehicle body 1 away from the discharge port 5, and is connected to the lower side of the vehicle body 1 through a handle bracket 8. The handle 7 is convenient for the staff to drive the device to move, and the handle bracket 8 strengthens the firmness of the connection between the handle 7 and the vehicle body 1, so that the control of the vehicle body 1 is more stable when transporting bulk materials, thereby improving the stability of the device when in use.

[0029] In this embodiment, one end of the back guide plate 21 is connected to the bottom plate inside the vehicle body 1, and the other end is connected to the top plate inside the vehicle body 1, and the angle a between the back guide plate 21 and the bottom of the vehicle body 1 is between 90° and 135°, so that the bulk material on the top flows along the inclined direction of the back guide plate 21 during the downward flow under gravity, which facilitates the outflow of the bulk material and improves the unloading efficiency of the device.

[0030] In another embodiment, the left and right side wall panels inside the vehicle body 1 are also inclined and are inclined toward the middle of the vehicle body 1, so that the longitudinal section of the vehicle body 1 is funnel-shaped, which facilitates the flow of bulk materials and further improves the efficiency of the device unloading.

[0031] In this embodiment, one end of the bottom guide plate 22 is connected to the plate surface of the back guide plate 21, and the other end is connected to the bottom plate at the bottom of the discharge port 5, and the angle b between the bottom guide plate 22 and the back guide plate 21 is between 90° and 135°, which can enable the bulk material to flow toward the discharge port 5 under the action of its own gravity, without the need for manual dumping, flipping, and turning up of the vehicle body 1, thereby reducing the labor intensity of the staff and improving the practicability of the device.

[0032] In this embodiment, three central guide plates 23 are provided, and the left and right ends are respectively connected to the left and right side plates inside the vehicle body 1, and the upper and lower ends of the central guide plate 23 are not in contact with the vehicle body 1. The angle c between the central guide plate 23 and the top of the vehicle body 1 is between 90° and 135°. The central guide plate 23 has a blocking effect on the flow of bulk material in the vehicle body 1 to a certain extent, avoiding the bulk material from suddenly rushing to the discharge port 5 during unloading and causing accidents, thereby improving the safety and stability of the device.

[0033] In this embodiment, the wheel cleaning assembly 3 includes a wheel scraper 31, one side of the wheel scraper 31 is arranged on the top of the collecting box 32, the other side of the wheel scraper 31 is in contact with the wheel 6, and the wheel scraper 31 is inclined toward one side of the collecting box 32, and the position where the collecting box 32 is connected to the wheel scraper 31 is open, which is used to collect foreign matter scraped from the wheel 6 by the wheel scraper 31, and the collecting box 32 is arranged on a buffer bracket 33. The buffer bracket 33 is made of a slender metal plate with a certain flexibility. The top of the buffer bracket 33 is arranged at the bottom of the vehicle body 1, and a spring mounting frame is arranged at the bottom of the vehicle body 1 on the side of the buffer bracket 33 close to the wheel 6, and a buffer spring 34 is arranged on the spring mounting frame. The buffer bracket 33 is connected to the spring mounting frame through the buffer spring 34, and the buffer spring 34 is preset with a stretched elastic potential energy, so that the buffer spring 34 pulls the buffer bracket 33 toward the wheel 6, so that the wheel scraper 31 can always maintain effective contact with the surface of the wheel 6, thereby improving the practicality of the device.

[0034] In this embodiment, an outlet baffle 9 is also included. The outlet baffle 9 is arranged on one side of the discharge port 5 and blocks the discharge port 5. The upper side of the outlet baffle 9 is movably connected to the vehicle body 1, and the lower side of the outlet baffle 9 is connected to the bottom guide plate 22 through a latch 10. When the latch 10 is pulled out, the bottom of the outlet baffle 9 is opened, and the top of the outlet baffle 9 is rotatably connected to the vehicle body 1, so that the bulk material can flow out through the discharge port 5, which is convenient for the transfer and unloading of the bulk material and improves the practicability of the device.

[0035] In this embodiment, the cross-sections of the feed port 4 located on the inner and outer sides of the vehicle body 1 are both conical, and the feed port 4 is covered with a feed cover plate 11, and the feed cover plate 11 can also be inserted on the feed port 4 to provide better stability. The conical opening at the upper part of the feed port 4 facilitates the entry of bulk material into the vehicle body 1, and the conical opening at the lower part of the feed port 4 prevents fine bulk material from flying and causing dust pollution after the bulk material enters the vehicle body 1, thereby protecting the environment and the physical and mental health of the staff. The feed cover plate 11 prevents the splashing of bulk material during the movement of the vehicle body 1, thereby improving the reliability and safety of the device.

[0036] Working principle: First, use the latch 10 to temporarily fix the discharge baffle 9 to prevent the citric acid bulk material from flowing out; open the feed cover 11, and the citric acid bulk material enters the vehicle body 1 through the feed port 4. During the collection process, the conical feed port 4 can prevent splashing and dust caused by excessively fine citric acid bulk material. After collecting the citric acid bulk material, close the feed cover 11, and the staff pushes or pulls the vehicle body 1 through the handle 7 to transfer the citric acid bulk material to the collection barrel; pull out the latch 10, and the citric acid bulk material enters the collection barrel through the discharge port 5. During the discharge process, the back guide plate 21 and the bottom guide plate 22 have a certain inclination angle. The citric acid bulk material can use its own fluidity to enter the collecting barrel. At the same time, the middle guide plate 23 has a certain effect of hindering the flow of the citric acid bulk material, preventing the citric acid bulk material from gushing out instantly and causing leakage accidents. In the process of discharging the citric acid bulk material, there is no need to tip, overturn, or flip the vehicle body 1, which can greatly reduce the labor intensity of the staff; during the movement of the vehicle body 1, the wheel scraper 31 removes foreign matter that may adhere to the wheel 6 and collects it in the collection box 32. During the forward movement of the device, the buffer spring 34 can maintain the effective contact between the wheel scraper 31 and the wheel 1, thereby improving the practicability of the device.
