DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. The following description is based on examples, but the scope of protection of the present invention should not be limited thereto.

[0024] The directions in this specification and the accompanying drawings are as follows:

[0028] Figure 4 and 5 The front is the actual top, the inside is the actual bottom; the right side is the actual right side, the left side is the actual left side; the top and bottom are the actual back and front respectively.

[0029] The four-door weighing transfer vehicle of this embodiment is composed of a vehicle body, a weighing assembly and a moving assembly, and the vehicle body, the weighing assembly and the moving assembly are stacked in sequence from top to bottom.

[0030] The vehicle body is composed of a vehicle chassis 11, two or more (four in this example) lower pressure plates 5, a left vehicle plate 13, a right vehicle plate 6, two front and rear upper doors 10 and two front and rear lower doors 12.

[0031] The chassis 11 is a rectangular frame, topped with a smooth, thin plate and slightly raised blocks on its left and right sides. Within this frame, one to three (two in this example) fore-aft reinforcement beams are added to enhance strength and rigidity while facilitating the installation of the weighing components. (Two transverse beams are also added on the right side for mounting the right weighing components.)

[0032] Four lower pressure plates 5 (the two on both sides are slightly narrower and the two in the middle are slightly wider) are laid on the thin plate above the chassis 11, and a packing rope placement groove 25 is left between each two plates for placing the packing rope; the outer sides of the two plates on both sides (the left side of the left plate and the right side of the right plate) and the inner sides of the left vehicle plate 13 and the right vehicle plate 6 may also retain or not retain the narrower groove.

[0033] The left and right panels 13 and 6 are both rectangular frames with a central reinforcement column. The inner surfaces of the left and right panels 13 and 6 are covered with smooth, thin plates to facilitate material compression (and prevent damage during compression, the same applies below). The lower edge of the left panel 13 is pivotally hinged to a pad on the left side of the chassis 11 via two lower left panel hinges 21. The right panel 6 is fixed to a pad on the right side of the chassis 11.

[0034] A limiting plate 20 is also fixed in the middle of the left side of the vehicle chassis 11. The upper middle to lower parts of the limiting plate 20 are connected to the upper part of the middle of the left side of the vehicle chassis 11 and the pad. The upper part of the limiting plate 20 extends upward a short distance to block the lower part of the left vehicle plate 13.

[0035] Since the lower end of the left side panel 13 is rotatably hinged to the pad on the left side of the chassis 11 through two left side panel lower hinges 21, the left side panel 13 can rotate to the left around the left side panel lower hinge 21. Therefore, when the material bag is stuck during use later, it can be swung to the left to remove the material bag. Although the limiting plate 20 can limit the swinging of the left side panel 13, the part of the limiting plate 20 blocking the lower part of the left side panel 13 (usually 3-10 cm) is only a small section, so it does not affect the small swing.

[0036] It is mainly used to facilitate the opening and closing of the front and rear side upper doors 10 and the front and rear side lower doors 12.

[0037] The front and rear upper doors 10 and the front and rear lower doors 12 are rectangular frames with two reinforcing columns in the middle. The inner surfaces of both doors are paved with smooth, thin panels. The right sides of the front and rear upper doors 10 and the front and rear lower doors 12 are pivotally hinged to the upper and lower portions of the front and rear sides of the right vehicle panel 6 via eight door hinges 9. A door collision avoidance gap 24 is provided between the front and rear upper doors 10 and the front and rear lower doors 12 to prevent collisions and possible closure during door opening and closing. A gap similar to the door collision avoidance gap 24 is also provided between the lower sides of the front and rear lower doors 12 and the upper surface of the vehicle chassis 11.

[0038] A latching device (four in total) is also provided on the left side of the front and rear upper doors 10 and the front and rear lower doors 12, respectively. The latching device is composed of a latching plate 14, a hook 15, an operating handle 17 and a latching screw 16; the latching plate 14 is a rectangular plate, the lower part of which is provided with an upward hooking groove 26; one end of the latching plate 14 is hinged to the middle of the left side surface of the front and rear upper doors 10 and the front and rear lower doors 12 by the latching screw 16; the operating handle 17 is a cylindrical rod, which is arranged at the other end of the latching plate 14; the hook 15 is "L"-shaped, and the "one" part of its lower part is arranged at the upper and lower parts of the front and rear parts of the left side surface of the left vehicle plate 13 (that is, the inner side of the frame column).

[0039] The vehicle chassis 11, the left vehicle plate 13 and the right vehicle plate 6, as well as the two front and rear upper doors 10 and the two front and rear lower doors 12 together constitute the cavity (hereinafter referred to as the cavity) of the four-door weighing and transfer vehicle of this embodiment for accommodating the weighing, compression and packaging of agricultural products.

[0040] The weighing assembly is composed of a set of universal side weighing components, two sets of fixed side weighing components and a weighing display component.

[0041] The universal side weighing component is composed of a universal side pad 4 and a universal side weighing sensor 3. The universal side pad 4 is arranged in the middle of the right end of the bottom surface of the vehicle chassis 11, and the universal side weighing sensor 3 is arranged thereunder; the fixed side weighing component is composed of a fixed side pad 18 and a fixed side weighing sensor 19. The fixed side pad 18 is arranged at the front and rear sides of the left end of the bottom surface of the vehicle chassis 11, and the fixed side weighing sensors 19 are respectively arranged thereunder; the display component is composed of a weighing display device 8 and a weighing display device mounting frame 7. The upper part of the weighing display device mounting frame 7 (which can also serve as an armrest) is shaped like an inverted "E" and is arranged on the upper right side of the right vehicle plate 6. A support rod connected to the middle upper part of the reinforcing column in the middle of the right vehicle plate 6 is also arranged in the middle of its right side; the weighing display device 8 is arranged in the middle position of the upper part of the weighing display device mounting frame 7, which is shaped like an inverted "E".

[0042] Based on the principle that three points form a plane, the three load cells form an isosceles triangle with the universal load cell 3 as the vertex and the side formed by the two fixed load cells 19 as the base.

[0043] The moving assembly is composed of a group of universal side moving components and two groups of fixed side moving components.

[0044] The universal side moving component is composed of a universal caster 1 and a universal caster pad 2. The universal caster pad 2 is arranged at the lower part of the universal side weighing sensor 3, and the universal caster 1 is arranged below it; the fixed side moving component is composed of a fixed caster 23 and a fixed caster pad 22. The fixed caster pad 22 is arranged at the lower part of the fixed side weighing sensor 19, and the fixed caster 23 is arranged below it.

[0045] The signal lines of the universal side weighing sensor 3 and the two fixed side weighing sensors 19 are respectively connected to the weighing display device 8. The power supply of the weighing display device 8 can be a rechargeable battery or a rectified mains supply.

[0046] Before use, first open the weighing display device 8 on the four-door weighing transfer vehicle of this embodiment, and perform zeroing processing (i.e., adjust the weight of the entire vehicle body and the parts above to zero) through the buttons on the control screen.

[0047] When in use, first place the middle section of the packing rope in the packing rope placement groove 25 (its two ends go around the inner sides of the front and rear upper doors 10 and the front and rear lower doors 12, and are placed on the upper outer sides of the front and rear upper doors 10), and then fill the agricultural products to be packaged (such as tobacco leaves, kelp, etc.) into the cavity from the top. When the material added to the cavity reaches the set weight, the weighing display device 8 will display the quantity and alarm at the same time to remind the operator to pay attention. Next, the four-door weighing transfer vehicle of this embodiment is sent to the compression equipment matched with it. Thereafter, the compression mechanism of the matching equipment presses downward into the cavity to compress the agricultural product materials therein; when the agricultural product materials in the cavity are compressed to a certain extent (i.e., before the extent close to damaging the universal side weighing sensor 3 and the two fixed side weighing sensors 19), the universal casters 1 and the fixed casters 23 will compress the sinking components on the platform of the matching equipment (refer to Chinese patent CN201921614534.8), allowing the weighing components and the moving components to sink, and allowing the chassis 11 to be placed on the load-bearing beams on the platform of the matching equipment. At this time, on the one hand, the weighing components and the moving components at the bottom of the chassis 11 no longer bear On the other hand, the pressure continuously compresses the agricultural product material in the cavity. When the pressure on the agricultural product material in the cavity reaches the set value, the downward pressure stops. Thereafter, the compression mechanism of the supporting equipment withdraws upward from the cavity, and the four-door weighing transfer vehicle of this embodiment is pushed out of the supporting equipment. Then, the operating handle 17 of the front and rear upper doors 10 rotates the trip plate 14 around the trip screw 16, allowing the hook groove 26 thereon to withdraw from the hook 15. Then, the front and rear upper doors 10 are opened, and the baling rope is tied around the compressed material. Then, according to the above steps, the front and rear lower doors 12 are opened, and the compressed and bundled material in the vehicle is pushed out, completing the loading, weighing, compression, and packaging steps. Thereafter, according to the reverse steps described above, the front and rear lower doors 12 and the front and rear upper doors 10 are closed in sequence. At this point, the above steps can be repeated.

[0048] The four-door weighing and transferring vehicle of the utility model is matched with compression equipment and can be used for weighing, compressing and packaging tobacco leaves as well as leafy and stem agricultural products such as rice straw, wheat straw and kelp.
