Description

A special connecting piece for milking parlor fence

technical field

The invention relates to the field of animal husbandry machinery, in particular to a special connecting piece for a milking parlor fence.

Background technique

With the continuous development of China's dairy industry, more and more attention has been paid to the construction and use of machinery and equipment in dairy farms, and they are developing in the direction of precision, convenience and durability. Among them, the milking parlor is the core of the entire ranch, so its Design level and construction quality are particularly important. Cows go to the milking parlor to line up for milking every day. In order to ensure that the cows can actively walk and wait in line in the milking parlor according to the prescribed route, it is necessary to set up fences in the relevant areas of the milking parlor to guide the cows to walk in the correct area. Cows in different directions interact with each other. Do not interfere and disturb. Therefore, the fence in the milking parlor becomes an important facility. If the fence in a certain place is defective, it will cause the cows to walk through the gap and disrupt the order of the milking parlor. However, the individual cows are too heavy and the cows in the queue are connected end to end. Once the order is disordered, It takes a lot of time and manpower to readjust, and failure to milk in time can lead to a rapid increase in the incidence of mastitis in cows.

The fencing of the milking parlor in most of the pastures in China is welded and then painted with anti-rust paint (that is, four round pipes are welded horizontally with a certain size between two pre-embedded columns); some pastures also use fence connectors to connect The vertical column and the horizontal horizontal pipe are usually connected by the traditional clamping method, but the design is not well thought out, which is counterproductive. In the actual construction process, the design and construction of the above-mentioned railings have the following deficiencies:

1. Dairy cows are relatively heavy, and the impact force is relatively large. Therefore, in order to ensure the strength of the fence weld, it is necessary to require the uprights of the fence to be welded with the horizontal horizontal pipe. The design requires cutting the two ends of the horizontal horizontal pipe into arcs, but in practice During the construction process, due to the limitations of processing capacity and equipment, the design requirements cannot be met. The two ends of the horizontal tube are often smashed flat, and then the flattened horizontal tube is hard smashed into the column for welding. It is not easy to control, and sometimes it needs to be cut again, which is labor-intensive and time-consuming.

2. Since 1/4 of the length of the column needs to be buried under the concrete floor, it is difficult to ensure the parallelism and verticality of the two adjacent columns during the pre-embedding process, which results in the length of 4 horizontal horizontal pipes required between the two columns No wait, the error can reach 2 cm, so the size of the four horizontal horizontal pipes must be measured first, and then the material should be cut, and the round pipes should be numbered to prevent mixed use, which will seriously delay the construction progress.

3. Since the milking parlor works 24 hours a day, there are acid and alkali corrosive smells such as cow dung and urine everywhere, and the welds need to be repainted with anti-rust paint for about one year, otherwise the welds are easy to corrode and crack, and the maintenance cost will increase in the later stage of the project. big.

4. The fences connected by traditional clamps are used. The horizontal horizontal tube is designed on the eccentric side of the outer skin of the column. The connecting bolts protruding from the traditional clamps often scratch the cow body, which brings troubles to the management of the pasture. Due to the eccentric installation, the range of activities of the cows is reduced, and when multiple cows walk together, they are more crowded and scratch the cow body more easily.

Contents of the invention

In order to solve the above-mentioned problems, the present invention proposes a special connecting piece for the fence of the milking parlor.

The special connector for the fence of the milking parlor of the present invention is divided into two types of clamps, special clamps for ends and special clamps for 90° corners. The above three types of clamps are all integrated steel castings with a thickness of 5mm. The vertical direction is a column sleeve, and the horizontal direction is one or two horizontal tube sleeves, wherein the diameter of the column sleeve is 90mm and the length is 70-90mm; the diameter of the horizontal tube sleeve is 44mm and the length is 50-60mm ; Set screw bosses on the outside of the column casing and the horizontal tube casing respectively, the length is consistent with the length of the casing, the width is 12mm, and the thickness is 3.5mm; one or two M10 bosses are respectively set on the screw bosses Threaded hole.

Further, on the platforms on both sides of the horizontal pipe casing of the pair-hugging type holding card, on the platforms on both sides of the horizontal pipe casing pipe of the pair-embracing type holding card, bolt bosses with a thickness of 3mm are respectively set, and each bolt boss Set a hole with a diameter of 8.5mm on it.

Further, an M10 threaded hole is respectively set on the screw bosses of the upright sleeve and the horizontal tube sleeve of the pair-hugging clamp.

Further, two M10 threaded holes are respectively set on the screw bosses of the column sleeves of the special clamps at the ends and the special clamps at 90° corners, and one M10 threaded hole is respectively set on the screw bosses of the horizontal pipe sleeves.

Preferably, the length of the column casing is 80mm, and the length of the horizontal pipe casing is 50mm.

At present, the outer diameter of the pre-embedded columns of the most commonly used milking parlor fences in pastures is 88mm, and the outer diameter of the horizontal horizontal tubes is 42mm. The inner diameter of the pipe is 44mm, which can be matched with the building pipe fittings that have been used or will be used in most pastures, so it is compatible. For the fence of the milking parlor that needs to be maintained and modified, the old column and horizontal pipe that have not been damaged can be used directly. Cooperating with the special connecting piece of the present invention, the maintenance cost of the fencing of the milking parlor is greatly saved, and at the same time, a stronger and more durable fencing is obtained, and the cows also obtain a wider action area.

Because the special connecting piece of the present invention is used on the pasture structural material, the diameter of the pasture construction pipe fittings is all thicker, and the length of the sleeve pipe is not much different from the diameter of the connected pipe fittings, and even the length is equal to less than the diameter of the pipe fittings, which can maximize the Fasten the pre-embedded columns and horizontal horizontal pipes. Moreover, the force of cows colliding with the fence is also relatively large. In order to ensure the firmness of the connecting piece, wider and thicker screw bosses are set on the column casing and horizontal pipe casing of the connecting piece. A bolt boss is added to the platforms on both sides of the casing. These bosses can play the role of reinforcing ribs, which enhance the fastening effect of the clamp on the column and the horizontal pipe, and can also effectively resist the conduction of the cattle body when it hits the fence. The traction force increases the service life of the connecting parts.

The present invention adopts M10 screws and bolts with a diameter of 8.5mm to fasten together firmly the connectors, the pre-embedded uprights and the horizontal tubes, and will not loosen or break unless subjected to a particularly large impact force. The entire fence will not shift under the use or slight impact of cattle.

During installation, when the pre-embedded column and the horizontal horizontal tube are in the shape of a cross, use the opposite-hugging clamping connection, and the bolts between the two clamping clamps are fastened through the bolt boss, and the elastic force compresses the horizontal tube, and the pre-embedded column Fasten through the screw boss with a screw between the horizontal tube and the horizontal tube. When the pre-embedded column and the horizontal pipe have a 90° corner, use the special clamp at the 90° corner, and use the screw to pass through the screw boss for fastening. The end of the fence adopts a special clamp for the end, and is fastened with a screw through the screw boss.

The beneficial effects of the present invention are as follows:

1. If the error between the positions of the pre-embedded columns is less than 3 cm, they can be used normally. After adopting the special connecting piece of the present invention, there is no need to cut arcs at both ends of the horizontal horizontal tube, only need to insert the connecting piece into the column first, and then fasten the horizontal tube on the connecting piece, the position accuracy of the pre-embedded column in general civil engineering construction The error within 2 centimeters can be guaranteed. Since the length of the horizontal horizontal tube sleeve of the connector of the present invention is about 5-6 cm, if the embedded columns are not parallel, the distance between the connection points of the horizontal horizontal tubes is different, as long as the error is less than 3 cm Within the range, the horizontal pipes cut according to one size can be used normally, and are fastened to the uprights through connectors to form a tightly connected fence.

2. Protect the body of the cow. All the contact parts between the special connecting piece and the cow body of the present invention have a circular arc transition, so that the cow will not be scratched.

3. Easy to use and easy to maintain. The connecting piece of the present invention is formed by integrated cast steel, and since it is made of cast steel and its surface is chrome-plated, it will not rust and corrode in the later stage, and there is no later maintenance cost.

4. Ensure that the center of the fence will not shift. The installation method of the connecting piece of the present invention ensures that the center of the pre-embedded column and the horizontal horizontal pipe are in the same plane. Even if it is a large milking parlor, the fence will not be gradually shifted during installation, and the range of activities of the cows will not be affected. There will be no scratches on the cow body.

5. The unique boss design enhances the fastening performance of screws and bolts. The connector of the present invention is designed with a 3.5mm screw boss and a 3mm bolt boss on the basis of a 5mm thick grip, which can save material and ensure the normal use of the screws and bolts, and the workers can operate conveniently and quickly during installation Tighten the bolt with a wrench, and at the same time, because the design of the boss plays the role of strengthening the ribs of the holding card, it can strengthen the overall strength of the holding card.
