[0027] like Figure 1-Figure 6 As shown, the utility model provides a split weighing device, including: a push plate elevator 1 and a weighing mechanism 2.

[0028] Among them, the push plate elevator 1 includes a push bin 11, a push assembly 12 and a conveyor chain 13. The push bin 11 is provided with a plurality of partitions 111. The plurality of partitions 111 are arranged in a staggered manner from top to bottom, and the plurality of partitions 111 are arranged tilted; the push assembly 12 includes a first driving component 121, a pushing bracket 122 and a plurality of push plates 123. The plurality of push plates 123 are arranged in a staggered manner from top to bottom, and the plurality of push plates 123 are tilted on the pushing bracket 122. The first driving component 121 is configured to drive the pushing bracket 122 to slide back and forth in the push bin 11. The push plate 123 is abutted against the inner side of the corresponding partition 111 and is configured to follow the pushing bracket 122 to slide back and forth along the surface of the partition 111; the conveyor chain 13 is arranged on the outer side of the partition 111 located at the top.

[0029] In addition, the weighing mechanism 2 includes a lower barrel 21, a flip cover 22, a second driving component 23 and a weighing device 24. The lower barrel 21 is hung on the weighing device 24 through a suspension rod 25. The flip cover 22 is rotatably arranged at the lower part of the lower barrel 21. The second driving component 23 is configured to drive the flip cover to flip to open and close the discharge port of the lower barrel.

[0030] Among them, the lower barrel is arranged below the conveyor chain, and the weighing device is arranged above the conveyor chain; one end of the conveyor chain extends between the lower barrel and the weighing device, and the conveyor chain is configured to convey materials to fall into the lower barrel below.

[0031] Specifically, for bulk materials, there is a situation where the size and weight are inconsistent. In this way, in the process of quantitative feeding, it is necessary to weigh them specifically, and it is impossible to rely on the number of bulk materials to calculate their weight. The bulk materials are placed in the push bin 11, so that the bulk materials can be lifted one by one by the multiple push plates 123 of the push assembly 12 in cooperation with the partition 111. Under the driving action of the first driving component 121, the push bracket 122 will drive the multiple push plates 123 to move back and forth along the partition 111, so that the push plates 123 move back and forth on the inner surface of the corresponding partition 111. During the reciprocating movement of the push plates 123, the push plates 123 at different height positions can push the bulk materials at the bottom of the push bin 11 to move upward step by step. Finally, the push plate 123 cooperating with the partition 111 at the top pushes the bulk materials upward and over the partition 111 at the top to fall onto the conveyor chain 13 outside the push bin 11.

[0032] When the bulk material is being conveyed on the conveyor chain 13 , the bulk material moves to the end of the conveyor chain 13 and falls from the conveyor chain 13 into the lower material barrel 21 .

[0033] As for the weighing mechanism 2, it is a separate structure from the push plate elevator 1. The weighing device 24 is arranged above the conveying chain 13, and the lower barrel 21 is suspended on the weighing device 24 through the suspension rod 24. The block material falling into the lower barrel 21 can be weighed by the weighing device 24, and when the block material in the lower barrel 21 weighed by the weighing device 24 reaches the set weight range, the push plate elevator 1 can be triggered to stop running to prevent excessive block materials from being transported to the lower barrel 21. At the same time, the second driving component 23 can be started to drive the flip cover plate 22 to rotate and open the discharge port of the lower barrel 21 for feeding.

[0034] Among them, for the weighing mechanism 2, during use, it can be equipped with a support frame, which is used to meet the requirements of fixed installation of the weighing device 24, and the lower barrel 21 is suspended on the weighing device. The support frame can be a steel structure frame, the weighing device 24 can be fixedly installed on the upper surface of the support frame by bolts or the like to obtain support, and the suspension rod 24 passes through the upper surface of the support frame to meet the requirements of suspension installation of the lower barrel 21. The lower end of the suspension rod 25 is fixedly connected to the upper end of the lower barrel 21, and the upper ends of multiple suspension rods 25 are fixed together on the pressure plate 26, and the pressure plate 26 presses on the weighing device 24.

[0035] In addition, the control of the various electrical components in the push plate lift 1 and the weighing mechanism 2 can be carried out through conventional control devices such as PLC, and the specific control program is not limited or elaborated here.

[0036] During the actual assembly process, for the conveyor chain 13, the height difference between it and the top surface of the top partition 111 can be designed to be smaller, so that after the block material falls from the partition 111 onto the conveyor chain 13, the impact force of the block material on the conveyor chain 13 is smaller, thereby ensuring that the conveyor chain 13 can be used reliably.

[0037] Furthermore, the flip cover includes two symmetrically arranged baffles 221, the baffles 221 are rotatably disposed on the lower barrel 21, and a rotatable connecting rod 222 is also disposed on the baffle 221;

[0038] The second driving component is a cylinder, and a driving rod 231 is provided on the piston rod of the cylinder, and the end of the driving rod is hinged to the corresponding connecting rod.

[0039] Specifically, the flip cover adopts a split structure, with two symmetrically arranged baffles 221, and the two baffles 221 can be synchronously rotated in opposite directions on the lower barrel 21 to realize the opening and closing of the discharge port of the lower barrel 21. In addition, the second driving component adopts a cylinder, and the piston rod of the cylinder reciprocates to drive the connecting rods 222 on both sides to move through the driving rod 231 to realize the synchronous and opposite rotation of the two baffles 221.

[0040] Among them, the lower end of the lower barrel is in a conical structure; one baffle is arranged on one side of the lower end of the lower barrel, and the other baffle is arranged on the other side of the lower end of the lower barrel.

[0041] Furthermore, a sieve plate 14 is provided in the pushing bin, and a plurality of sieve holes (not marked) are provided on the sieve plate. The sieve plate 14 is arranged obliquely in the pushing bin 11 , and a gap is formed between the lower end of the sieve plate 14 and the adjacent partition 111 .

[0042] Specifically, for bulk materials, in order to reduce the impact of dust particles and other debris during transportation, after the bulk materials are put into the pushing bin 11, the bulk materials fall on the sieve plate 14 and can pass through the sieve holes on the sieve plate 14 to screen and remove impurities.

[0043] The bottom of the push bin is also provided with a slag discharge port (not marked), which is located directly below the sieve plate, and the slag discharge port of the push bin is also provided with a slag discharge channel 15. Specifically, impurities fall from the sieve holes of the sieve plate 14 and are discharged from the slag discharge channel 15 through the slag discharge port.

[0044] Furthermore, in order to achieve effective screening of the bulk materials put into the push-pull 11 , a feeding channel 16 is further provided above the pushing bin; the feeding channel 16 is located above the sieve plate 14 .

[0045] Specifically, the bulk material can be guided to slide into the push-pull bin 11 through the feed channel 16, and the bulk material will fall onto the screen plate 14 below for impurity screening. As for the feed channel 16, it can be suspended above the push bin 11, and the feed channel 16 can be fixedly installed with the support iron frame located in the push-pull bin 11, or other conventional installation methods can be used to meet the requirement that the feed channel 16 is suspended above the push bin 11, which will not be limited or repeated here.

[0046] Based on the above technical solution, optionally, the pushing component 12 includes a support frame 124, and the pushing bin 11 and the conveying chain 13 are arranged on the support frame 124;

[0047] The support frame 124 is further provided with a linear guide rail 125 , which is arranged obliquely, and the pushing bracket 122 is slidably provided on the linear guide rail 125 .

[0048] Specifically, in order to facilitate the installation of the first driving component 121 and guide the reciprocating movement of the pushing bracket 122, the first driving component 121 and the pushing bracket 122 are installed on the support frame 124, and correspondingly, the pushing bin 11 can be erected on the top of the support frame 124.

[0049] The support frame 124 is provided with a linear guide rail 125, which can guide the pushing bracket 122, so that the pushing bracket 122 can drive the push plate 123 to move back and forth smoothly on the partition 111, so that the push plate 123 can steadily push the block logistics upward on the partition 111.

[0050] In addition, the first driving component 121 may be a driving device with a telescopic function, such as a driving cylinder, an electric push rod, etc., which will not be limited or elaborated herein.

[0051] Furthermore, in order to reduce manufacturing costs and improve pushing reliability, a bent pushing portion 1231 is provided on the top of the pushing plate 123 , and the bent pushing portion 1231 is bent and extended toward the direction of the partition 111 corresponding to the pushing plate 123 .

[0052] Specifically, a bent push portion 1231 is provided at the top of the push plate 123, and the bent push portion 1231 is used to increase the contact area with the bulk material, thereby more smoothly pushing the bulk material upward. At the same time, the bent push portion 1231 can effectively abut against the inner surface of the partition 111, avoiding the block material from getting stuck due to the large gap between the push plate 123 and the partition 111. In addition, for the push plate 123, it only needs to use the bent push portion 1231 at the top to meet the requirements of pushing materials and avoiding material jamming. The overall thickness of the push plate 123 is relatively small, which is conducive to reducing manufacturing costs.

[0053] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
