Description

Technical Field

[0001] The utility model belongs to the technical field of urea packaging, and in particular relates to a quantitative continuous automatic packaging mechanism for urea. Background Art

[0002] Urea, also known as carbamide, is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal and one of the simplest organic compounds. It is the main nitrogen-containing end product of protein metabolism and decomposition in mammals and some fish. It is also the nitrogen fertilizer with the highest nitrogen content. As a neutral fertilizer, urea is suitable for various soils and plants. It is easy to store, easy to use, and has little destructive effect on the soil. It is currently a chemical nitrogen fertilizer with a large usage.

[0003] With the development of science and technology, there have emerged automatic packaging mechanisms that can quantitatively and continuously package finished urea granules. The quantitative continuous automatic packaging mechanisms currently on the market directly deliver the finished urea granules to packaging bags or packaging barrels when in use. Since urea is water-absorbent, urea will agglomerate when it comes into contact with air during the packaging process, resulting in a large amount of agglomerated urea in the packaging bags or packaging barrels. When fertilizing the soil or plants, the agglomerated urea needs to be manually crushed into granules, which increases the labor intensity of the staff. If it is used directly without being crushed, it will lead to uneven fertilization, which will affect the growth of plants or crops.

[0004] Therefore, a urea quantitative continuous automatic packaging mechanism is proposed. Utility Model Content

[0005] The utility model provides a quantitative continuous automatic packaging mechanism for urea, aiming to solve the above-mentioned problem.

A quantitative continuous automatic packaging mechanism for urea comprises: a conveyor; a conveyor belt arranged on the conveyor; and a fixing frame fixed to the top of the conveyor by bolts; a through cavity opened at the bottom of the fixing frame near the position just above the conveyor belt; a fixing plate fixed to the top of the fixing frame by bolts; a first electric push rod fixed to the top of the fixing plate by bolts; a lifting plate fixed to the output end of the first electric push rod; a through groove opened on the outer wall of the conveyor; a support plate running through the inside of the through groove; a transverse plate fixed to the outer wall of the fixing plate by bolts; a second electric push rod fixed to the top of the transverse plate by bolts; a lifting plate fixed to the output end of the second electric push rod; a feeding pipe embedded in the central position of the bottom of the lifting plate; a urea metering pump fixed to the central position of the top of the transverse plate by bolts; a urea storage box fixed to the top of the urea metering pump by bolts; a corrugated pipe fixed between the feeding pipe and the urea metering pump by bolts; a feeding hole opened at the central position of the top of the fixing frame; and a vacuum pump fixed to the outer wall of the fixing frame by bolts.

[0007] Preferably, the lifting plate and the supporting plate are on the same vertical plane.

[0008] Preferably, there are two fixing plates in total, and the two fixing plates are symmetrically arranged on the top of the fixing frame, and the cross-section of the support plate is an L-shaped structure.

[0009] Preferably, the outer side walls of the lifting plate and the fixing frame are in contact with each other, and the widths of the lifting plate and the conveying belt are the same.

[0010] Preferably, there are two second electric push rods in total, and the two second electric push rods are symmetrically arranged on the top of the cross plate.

[0022] It should be noted that, since urea is hygroscopic, urea will agglomerate when it comes into contact with air during the packaging process, resulting in a large amount of agglomerated urea in the packaging bag or packaging barrel. In this embodiment, the lifting plate 7 and the support plate 9 respectively squeeze and support the conveyor belt 2, so that the cavity 4 can be made into a relatively sealed environment, and the air and water vapor in the cavity 4 can be extracted, so that the urea will not come into contact with the air during quantitative dispensing and packaging, and will not be damp and agglomerated, thereby ensuring that the packaged urea particles are distinct, which is convenient for the subsequent urea fertilization. By inserting the dispensing pipe 13 into the urea packaging container, splashing of urea can be avoided during dispensing, thereby ensuring the accuracy of quantitative urea packaging.

[0023] Specifically, in this embodiment, the scheme mainly includes a fixing frame 3 and a lifting plate 7. When in use, a container for urea packaging is placed on the conveying belt 2 in the conveyor 1. The conveying belt 2 conveys and moves the container.

The lifting plate 7 moves downward along the outer wall of the fixing frame 3. The lifting plate 7 squeezes the conveying belt 2. The support plate 9 supports the conveying belt 2 at the pressure point. The lifting plate 7 blocks the through cavity 4. The vacuum pump 18 works to extract the air in the through cavity 4, thereby reducing At this time, the second electric push rod 11 drives the lifting plate 12 to move downward through the output end on one side thereof, the feeding pipe 13 on the lifting plate 12 is inserted into the containing container, the bellows 16 is stretched, and the urea metering pump 14 adds the urea in the urea storage tank 15 into the containing container through the bellows 16 and the feeding pipe 13 to realize the quantitative packaging of urea. After the loading and packaging is completed, the lifting plate 7 moves upward, the through cavity 4 is exposed, the conveyor 1 works again, and the conveyor belt 2 transports the next containing container to the inside of the through cavity 4, and makes the containing container located directly under the feeding pipe 13, to realize quantitative continuous automatic packaging.
