Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of concrete additive dispensing tools, and particularly relates to a quantitative dispensing device for concrete additives. Background Technology
[0002] Concrete additives, also known as concrete admixtures, are substances added during the concrete preparation process, other than cement, water, and aggregates. Their main purpose is to improve the workability of concrete, increase its strength, durability, and impermeability, and can also regulate the hardening rate of concrete.
[0003] To ensure optimal performance, concrete and its additives need to be mixed in a specific ratio. While weighing is acceptable for large batches, it is very cumbersome for small batches. Using a spoon makes it difficult to ensure that each spoonful is of uniform quantity, which makes it difficult to measure the amount of concrete needed for small quantities.
[0004] To address this issue, we propose a quantitative addition device for concrete additives. Utility Model Content
[0005] The purpose of this invention is to solve the problem of the inconvenience of quantitatively adding small amounts of concrete, and to propose a quantitative addition device for concrete additives.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A metering device for concrete additives includes a scoop, a guide rail fixedly connected to the upper part of the scoop, a pusher slidably mounted on the guide rail, and a spring plate connecting the guide rail and the pusher. The front part of the spring plate is fixedly connected to the pusher, and the rear part of the spring plate is fixedly connected to the guide rail. A push plate is fixedly connected to the front part of the pusher. By holding the guide rail and operating it to move the scoop to dispense additives, the spring plate is pressed down to flatten it, and the spring plate pushes the pusher forward, leveling off any excess additives to ensure that each scoop contains the same amount of additive, facilitating metered dispensing.
[0008] Preferably, a widening plate is fixedly connected to the rear of the spring. The widening plate increases the range of force between the spring and the finger, improving operating comfort.
[0009] Preferably, the spoon includes a square box and a handle, one end of the handle being fixedly connected to the square box; one end of the guide rail being fixedly connected to the square box; the pusher frame being in movable contact with the square box; and the lower end of the pusher frame being in movable contact with the handle. Holding the handle and the end of the guide rail, and then operating the handle to move the square box to pick up the target concrete additive, makes it convenient to hold and operate the spoon.
[0010] Preferably, the spoon further includes a reinforcing block, the lower part of which is fixedly connected to the tail of the handle; the upper part of which is fixedly connected to the guide rail. By connecting the reinforcing block to the tail of the handle and the guide rail, the stability of the distance between the tails of the handle and the guide rail is increased, thus facilitating increased stability between the spoon and the guide rail.
[0011] Preferably, the spoon further includes a stop block, which is fixedly connected to the lower end of the handle. The stop block is used to block the outside of the hand, preventing the hand from slipping off the handle after gripping it.
[0012] Preferably, the guide rail includes a grip plate with a guide groove hollowed out at its upper end; the pusher is slidably installed in the guide groove, one end of the grip plate is fixedly connected to the square box, and the other end of the grip plate is fixedly connected to the reinforcing block. After pressing the widening plate by hand, the spring clip is lowered forward, thereby pushing the pusher, which in turn guides the pusher to slide through the guide groove, facilitating the pusher to push out excess concrete additive.
[0013] Preferably, the push frame includes a slider, a push bar, and a slider. One end of the slider is fixedly connected to the push bar, and the other end of the slider is fixedly connected to the upper end of the slider. The lower end of the push plate is fixedly connected to the upper end of the push bar. The slider is slidably installed in the guide groove. The slider is in movable contact with the grip plate. The lower end of the push bar is in movable contact with the square box. The push bar is fixedly connected to the head of the spring piece. When the push bar is pressed, the spring piece pushes the push bar, causing the push bar to drive the slider and the slide bar forward, facilitating the operation of the push frame sliding.
[0014] In summary, the technical effects and advantages of this utility model are as follows:
[0015] 1. Hold your hand on the guide rail, then operate the guide rail to move the spoon to take the additive. Next, press the spring to flatten the spring downwards, and use the spring to push the pusher forward. Use the pusher to flatten the excess additive, so that the amount of additive in each spoon is the same, making it convenient to take the correct amount.
[0016] 2. Hold the handle and the end of the guide rail with your hand, then operate the handle to move the square box to pick up the target concrete additive, making it easy to hold the spoon.
[0017] 3. Use reinforcing blocks to connect the handle and the end of the guide rail to increase the stability of the distance between the handle and the end of the guide rail, which will help increase the stability between the spoon and the guide rail.
[0018] 4. After pressing the widening plate with your hand, the spring clip will bend forward, thereby pushing the pusher frame and guiding the pusher frame to slide through the guide groove, making it easier for the pusher frame to push out excess concrete additives.
[0019] 5. When the push bar is pressed, the spring plate pushes the push bar, causing the push bar to drive the slider and slide forward, making it easy to operate the push frame to slide. Attached Figure Description
