Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizer production, in particular to a compound fertilizer raw material transfer device capable of reducing dust diffusion. Background Art

[0002] Compound fertilizer raw materials need to be transported to production and processing equipment. Compound fertilizer raw materials may be bagged or unpackaged, and are usually transported using a transfer cart. An existing patent (Announcement No.: CN214057575U) discloses a raw material transfer cart for high-concentration compound fertilizer production. This utility model effectively alleviates the problem of dust diffusion by setting a collection device to absorb the dust generated by the bagged compound fertilizer raw materials due to road bumps. However, in actual applications, since the collection device is closer to the connecting handle side of the transfer vehicle body, the dust absorption capacity of the collection device gradually weakens from the side close to the connecting handle to the other side of the transfer vehicle body, making the dust generated on the side away from the collection device easy to diffuse outward, and its practicality needs to be improved. To this end, we propose a compound fertilizer raw material transfer device that reduces dust diffusion. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a compound fertilizer raw material transfer device which reduces dust diffusion.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] A compound fertilizer raw material transfer device for reducing dust diffusion is designed, including a transfer vehicle body, a shielding component is provided above the transfer vehicle body bucket, the shielding component includes a shielding cover located in the transfer vehicle body, push handles are installed on both sides of the transfer vehicle body, a lifting mechanism is provided between the push handles, the lifting mechanism includes a sliding seat that moves up and down, the sliding seat is connected to the shielding cover, and a collection device is provided on the transfer vehicle body and connected to the interior of the transfer vehicle body.

[0006] In the above solution, the shielding cover includes cover plate 1 and cover plate 2 arranged in an inverted V shape. Cover plate 2 is connected to cover plate 1 through a rotating shaft. A torsion spring is sleeved on the rotating shaft, with both ends respectively fixed to cover plate 1 and cover plate 2.

[0007] In the above solution, the bottoms of the cover plate 1 and the cover plate 2 are both covered with a felt layer.

[0008] In the above solution, a movable plate is provided on the shielding cover, and the tops of the cover plate 1 and the cover plate 2 are respectively connected to connecting columns through connecting seats, and the tops of the connecting columns are fixed to the movable plate.

[0009] In the above solution, the lifting mechanism also includes a support frame fixed on the transfer vehicle body, a screw is movably installed in the support frame, the sliding seat is threadedly connected to the screw, and the movable plate is connected to the sliding seat through a connecting arm.

[0010] In the above solution, a rotary handle coaxially connected to the screw rod is installed at the bottom of the support frame.

[0011] In the above solution, a mounting groove fixed to the transfer vehicle body is provided below the push handle, a hydraulic rod is installed in the mounting groove, and a rubber pad connected to the stroke end of the hydraulic rod is provided at the bottom of the mounting groove.

[0012] The advantages and beneficial effects of the present invention are that: by setting a shielding component, after the raw materials are loaded, the shielding cover is used to cover the opening of the transfer vehicle body bucket. Compared with the existing technology, even if the raw materials generate dust due to road bumps during transportation, the shielding cover can be used to close the opening of the transfer vehicle body bucket, completely blocking the path for dust to spread outward, and effectively preventing the dust from spreading outward. By setting a lifting mechanism and a movable plate, the sliding seat is moved along the screw by rotating the screw, driving the movable plate to move up and down, and then the shielding cover is moved up and down in the transfer vehicle body bucket. Compared with the existing technology, the shielding cover can be made to fit tightly against the raw materials, further compressing the space for dust diffusion, effectively preventing dust from spreading outward, and limiting the activity space of the raw materials in the transfer vehicle body, thereby improving the stability of raw material transportation.

DETAILED DESCRIPTION

[0017] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0018] See also Figure 1-2 The utility model provides a technical solution: a compound fertilizer raw material transfer device for reducing dust diffusion, comprising a transfer vehicle body 1, a shielding component 5 is provided above the bucket of the transfer vehicle body 1, and the shielding component 5 includes a shielding cover 52 located in the transfer vehicle body 1;

[0019] Specifically, the shielding cover 52 includes a first cover plate 521 and a second cover plate 522 arranged in an inverted V shape. The second cover plate 522 is connected to the first cover plate 521 via a rotating shaft 53. The rotating shaft 53 is provided with a torsion spring 54 at both ends thereof, which is fixed to the first cover plate 521 and the second cover plate 522 respectively. In a natural state, the first cover plate 521 and the second cover plate 522 form an inverted V shape. When the first cover plate 521 and the second cover plate 522 are subjected to pressure, causing the angle between them to change, the torsion spring 54 generates an elastic force, causing the first cover plate 521 and the second cover plate 522 to return to their original state, thereby facilitating automatic reset.

[0020] Furthermore, the bottoms of the first cover plate 521 and the second cover plate 522 are both covered with a felt layer 55. When the dust generated by the raw materials moves upward, the dust will directly adhere to the felt layer 55, preventing the dust from continuing to move, thereby helping to reduce dust diffusion.

[0021] Furthermore, a movable plate 51 is provided above the shielding cover 52, and the tops of the cover plate 1 521 and the cover plate 2 522 are movably connected to connecting posts 56 through connecting seats 57, and the tops of the connecting posts 56 are fixed to the movable plate 51; the shielding cover 52 is driven by the movable plate 51 by the connecting posts 56 to move up and down so as to adjust the position of the shielding cover 52. When the shielding cover 52 enters the transfer vehicle body 1, the former is simultaneously subjected to the force from the movable plate 51 and the raw materials, so that the shielding cover 52 is completely attached to the inner wall of the transfer vehicle body 1 on all sides, thereby suppressing the diffusion of dust outwards;

[0022] Specifically, by setting up the shielding component 5, after the raw materials are loaded, the shielding cover 52 is used to cover the opening of the bucket of the transfer vehicle body 1. Compared with the existing technology, even if the raw materials generate dust due to road bumps during transportation, the shielding cover 52 can be used to close the opening of the bucket of the transfer vehicle body 1, completely blocking the path for dust to spread outward, and effectively preventing dust from spreading outward.

[0023] Push handles 12 are installed on both sides of the transport vehicle body 1, and a lifting mechanism is provided between the push handles 12. The lifting mechanism includes a sliding seat 8 that moves up and down, and the sliding seat 8 is connected to the shielding cover 52;

[0024] Furthermore, the lifting mechanism further includes a support frame 6 vertically fixed on the transport vehicle body 1, a screw 7 is vertically movably installed in the support frame 6, a sliding seat 8 is threadedly connected to the screw 7, and both sides of the movable plate 51 are connected to the sliding seat 8 through a connecting arm 9;

[0025] Furthermore, a rotary handle 10 is mounted on the bottom of the support frame 6 and is coaxially connected to the screw rod 7. By rotating the rotary handle 10, the screw rod 7 is rotated, and the sliding seat 8 moves up and down along the screw rod 7, thereby driving the movable plate 51 to move up and down.

[0026] Specifically, by setting up a lifting mechanism and a movable plate 51, by rotating the screw 7, the sliding seat 8 moves along the screw 7, driving the movable plate 51 to move up and down, and then the shielding cover 52 moves up and down in the bucket of the transfer vehicle body 1. Compared with the existing technology, the shielding cover 52 can be closely attached to the raw material, further compressing the space for dust diffusion, effectively preventing dust from diffusing outward, and limiting the activity space of the raw material in the transfer vehicle body 1, thereby improving the stability of raw material transportation.

[0027] Furthermore, a mounting groove 2 fixed to the transfer vehicle body 1 is provided below the push handle 12, and a hydraulic rod 3 with a movable end facing vertically downward is fixedly installed in the mounting groove 2. A rubber pad 4 connected to the stroke end of the hydraulic rod 3 is provided at the bottom end of the mounting groove 2. The elastic force of the rubber pad 4 is used to reduce the impact force between the mounting groove 2 and the ground, thereby preventing the transfer vehicle body 1 from vibrating strongly due to the impact force, thereby improving the stability of the transfer vehicle body 1 and extending the service life of the mounting groove 2.

[0028] The transfer vehicle body 1 is provided with a collecting device 11 connected to its interior; the collecting device 11 is used to absorb the dust in the bucket of the transfer vehicle body 1, and has been disclosed in a raw material transfer vehicle for high-concentration compound fertilizer production with announcement number CN214057575U. The collecting device includes a stable base, an air suction pump, a connecting box, a connecting pipe, a collecting pipe and a discharge pipe. The collecting device 11 can be used to absorb the dust in the transfer vehicle body 1 to avoid a large amount of dust spreading outward when the shielding cover 52 is lifted.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
