Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, and in particular to the preparation of animal feed, specifically a feed salt addition device for feed processing. Background Technology

[0002] Salt is an important substance for maintaining the physiological functions of livestock and poultry. Therefore, when preparing feed on farms, feed salt (mainly sodium chloride) is usually added to the feed mixing tank to ensure the salt requirements of livestock and poultry.

[0003] To improve the accuracy of the proportion of feed salt, the feed salt to be added should be weighed before being added to the mixing tank. The required amount of feed salt should be weighed according to the formula before adding it to the mixing tank to avoid adding too much or too little, thus ensuring the health of livestock and poultry.

[0004] However, feed salt is prone to caking during transportation and storage due to changes in environmental temperature and humidity, forming lumps larger than 2 cm. The current method of directly adding it after weighing results in poor mixing uniformity between the feed and the feed salt, thus affecting the feeding effect on livestock and poultry. If large lumps of feed salt are manually picked out and broken up before being added to the mixing tank, the efficiency of feed preparation is significantly reduced. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a feed salt addition device for feed processing, which enables the crushing of large pieces of feed salt before they are added to the mixing tank.

[0006] This utility model is achieved through the following technical solution: a feed salt addition device for feed processing is provided, including a storage hopper and a belt scale located below the storage hopper. The discharge side of the belt scale is provided with a material distribution and crushing device. The material distribution and crushing device includes a shell, a partition plate and a primary material distribution plate fixed in the shell. A material chamber I is formed in front of the partition plate, and a material chamber II is formed behind the partition plate. Both material chamber I and material chamber II are provided with crushing mechanisms. The primary material distribution plate is inverted V-shaped and located above the partition plate. The front side plate of the primary material distribution plate extends downward to above the crushing mechanism in material chamber I, and the rear side plate of the primary material distribution plate extends downward to above the crushing mechanism in material chamber II.

[0007] This solution temporarily stores feed salt in a storage hopper, weighs the amount of feed salt to be added using a belt scale, and then puts the weighed feed salt into a material distribution and crushing device. Using the action of a primary material distribution plate, the feed salt is guided to the crushing mechanisms in material chamber I and material chamber II respectively, and large pieces of material are crushed by the crushing mechanisms in the two material chambers.

[0008] As an optimization, the crushing mechanism includes two crushing rollers rotatably connected to the housing, and a drive mechanism for driving the crushing rollers to rotate. The axes of the crushing rollers extend in the left-right direction, and the two crushing rollers are arranged in a front-back arrangement, forming a feed salt channel between the two crushing rollers. This optimized crushing mechanism adopts a double-crushing-roller structure, using the rotating two crushing rollers to convey the feed salt downwards. Large pieces of feed salt are crushed by the two crushing rollers as they pass through the feed salt channel, improving the reliability of crushing and preventing large pieces of feed salt from entering the feed mixing tank.

[0009] As an optimization, cleaning brushes are installed in front of the front crushing roller and behind the rear crushing roller in feed chamber I, with bristles extending to the corresponding crushing roller. This optimization scheme removes feed salt adhering to the crushing roller by setting up cleaning brushes, thus reducing the error in feed salt addition.

[0010] As an optimization, a baffle plate is fixed above the cleaning brush, with the distance between the baffle plate and the crushing roller not exceeding 5mm. In material chamber I, the front end of the front baffle plate is fixed to the front side wall of the shell, and the rear end of the rear baffle plate is fixed to the partition plate. In material chamber II, the front end of the front baffle plate is fixed to the partition plate, and the rear end of the rear baffle plate is fixed to the rear side wall of the shell. This optimization scheme, by setting baffle plates, prevents large pieces of feed salt from passing between the shell and the crushing roller, and between the crushing roller and the partition plate.

[0011] As an optimization, a secondary distribution plate, fixedly connected to the shell, is provided below the feed salt channel. The secondary distribution plate is inverted V-shaped, and drop channels are formed on its front and rear sides. This optimization scheme, by setting the secondary distribution plate, further distributes the feed salt falling from the feed salt channel, thereby increasing the surface area of ​​the feed salt as it falls, preventing the feed salt from piling up in the mixing tank, and facilitating the improvement of the uniformity of the mixing between feed and feed salt.

[0012] As an optimization, the surface of the crushing roller is fixed with several radially extending bosses, and the bosses of the two crushing rollers of the same crushing mechanism are staggered. This optimization scheme improves the crushing effect on large pieces of feed salt by setting bosses on the surface of the crushing roller, and avoids the problem that large pieces of feed salt cannot enter between the two crushing rollers.

[0013] As an optimization, the partition is a U-shaped plate with the opening facing downwards. The left and right ends of the partition are welded to the inner wall of the shell, and the two upper edges of the partition are welded to the two side plates of the primary material distribution plate. This optimized solution sets the partition as a U-shaped plate, which improves the structural strength of the shell and provides temporary support for the primary material distribution plate before welding, facilitating the assembly and welding operation and reducing the difficulty of assembly and welding.

[0014] As an optimization, the belt scale and the housing are fixed to the same chassis, and the housing is bolted to the chassis. The chassis has elongated holes for the bolts to pass through, and the length of the elongated holes is aligned with the material conveying direction of the belt scale. This optimized design, by fixing the belt scale and the housing to the same chassis, improves the overall integrity of the equipment. The elongated holes facilitate adjustment of the housing's front and rear positions, ensuring that the position of the primary distribution plate matches the location where the feed salt thrown by the belt scale falls.

[0015] The beneficial effects of this utility model are as follows: by setting a double-roller crushing mechanism, the feed salt after symmetrical measurement is crushed, avoiding large pieces of feed salt from entering the feed mixing tank, thereby improving the uniformity of feed and feed salt mixing; by setting a primary distribution plate and a secondary distribution plate, the falling area of ​​feed salt is increased, which is more conducive to the mixing of feed and feed salt.

[0021] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0022] like Figure 1 The feed salt addition device for feed processing is shown, including a storage hopper 1 and a belt scale 2 located below the storage hopper. The belt scale is equipped with a material distribution and crushing device 3 on the discharge side. Both the storage hopper and the belt scale adopt existing technology. The discharge port of the storage hopper is equipped with a valve to control the falling of the material. The belt scale is used to weigh the mass of the feed salt and throw the weighed feed salt into the material distribution and crushing device.

[0023] The material distribution and crushing device 3 includes a housing 5, a partition 8 and a primary material distribution plate 7 fixed inside the housing. A material chamber I is formed in front of the partition, and a material chamber II is formed behind the partition. Both material chamber I and material chamber II are equipped with crushing mechanisms.

[0024] Specifically, the primary distribution plate 7 is inverted V-shaped and located above the partition plate 8. The front side plate of the primary distribution plate extends downward to the crushing mechanism in the material chamber I, and the rear side plate of the primary distribution plate extends downward to the crushing mechanism in the material chamber II. By using the two inclined side plates of the primary distribution plate, the material is guided to the material chamber I and the material chamber II respectively, realizing primary distribution and allowing the material to fall better between the two crushing rollers of the crushing mechanism.

[0025] The partition 8 is a U-shaped plate with its opening facing downwards. The left and right ends of the partition are welded to the inner wall of the shell, and the two upper edges of the partition are welded to the two side plates of the primary material distribution plate. The side plates and top plate of the partition are welded to the shell, improving the structural strength of the shell. When welding the primary material distribution plate, the partition can be used to support it, reducing the difficulty of assembling and welding the primary material distribution plate.

[0026] The crushing mechanism includes two crushing rollers 6 rotatably connected to the housing, and a drive mechanism for driving the crushing rollers to rotate. The axis of the crushing rollers extends in the left-right direction, and the two crushing rollers are arranged in a front-back arrangement, forming a feed salt channel between the two crushing rollers. Several radially extending bosses 9 are fixed on the surface of the crushing rollers. The bosses of the two crushing rollers in the same crushing mechanism are staggered. The bosses prevent large pieces of feed salt from slipping on the crushing rollers, ensuring that large pieces of feed salt enter between the two crushing rollers for crushing.

[0027] The drive mechanism includes a motor 14 mounted outside the housing, which drives each crushing roller to rotate. The output shaft of the motor is coaxially fixed to the front crushing roller shaft in material chamber II via a coupling, and is connected to the front crushing roller shaft in material chamber I via a synchronous belt 13. Pulleys adapted to the synchronous belt 13 are mounted on the output shaft of the motor and the crushing roller shafts. The synchronous belt and pulleys are respectively provided with meshing teeth. The two crushing roller shafts in material chamber I and the two crushing roller shafts in material chamber II are respectively connected by gears 15, ensuring that the two crushing rollers of the same crushing mechanism rotate in opposite directions.

[0028] In feed chamber I, cleaning brushes 11 are respectively provided in front of the front crushing roller and behind the rear crushing roller. The bristles of the cleaning brushes extend to the corresponding crushing rollers. The brushes located on the front side are fixed to the front side wall of the housing, and the brushes located on the rear side are fixed to the partition plate. In feed chamber II, cleaning brushes 11 are also provided in front of the front crushing roller and behind the rear crushing roller. The bristles of the cleaning brushes extend to the corresponding crushing rollers. The brushes located on the front side are fixed to the partition plate, and the brushes located on the rear side are fixed to the rear side wall of the housing. The cleaning brushes are used to clean the feed salt adhering to the crushing rollers, reducing the amount of feed salt adhering to the crushing rollers.

[0029] A baffle plate 10 is fixed above the cleaning brush, and the distance between the baffle plate 10 and the crushing roller is no more than 5 mm. In material chamber I, the front end of the baffle plate on the front side is fixed to the front side wall of the shell, and the rear end of the baffle plate on the rear side is fixed to the partition. In material chamber II, the front end of the baffle plate on the front side is fixed to the partition, and the rear end of the baffle plate on the rear side is fixed to the rear side wall of the shell. Each baffle plate is inclined downwards. On the one hand, the baffle plates prevent large pieces of feed salt from passing between the shell and the crushing roller, and between the partition and the crushing roller. On the other hand, large pieces of feed salt between the baffle plate and the crushing roller are allowed to enter between the two crushing rollers under the action of the protrusion.

[0030] Below the feed salt channel is a secondary distribution plate 12 fixed to the shell. The secondary distribution plate 12 is inverted V-shaped, and the front and rear sides of the secondary distribution plate form drop channels respectively. The feed salt crushed by the crushing roller falls through the four drop channels arranged in front and behind under the action of the secondary distribution plate.

[0031] To improve the overall integrity of the equipment, the belt scale and the housing are fixed on the same chassis 4. The lower end of the support legs of the belt scale is connected to the chassis through a weighing sensor. The housing 5 is connected to the chassis 4 by bolts. The chassis has an elongated hole for the bolts to pass through, and the length direction of the elongated hole is consistent with the material conveying direction of the belt scale.

[0032] In this embodiment, the feed salt falling from the storage hopper 1 is weighed by a belt scale. When the weight of the feed salt reaches the required level, the discharge port of the storage hopper is closed, the drive motor of the belt scale is started, and the conveyor belt of the belt scale rotates, throwing the feed salt into the shell. Under the action of the primary distribution plate, the feed salt is divided into two streams, which enter the feed chamber I and the feed chamber II respectively. Small particles of feed salt fall through the feed salt channel, while large pieces of feed salt are crushed under the squeezing action of the crushing roller and also fall through the feed salt channel. During the falling process, the feed salt falling through the feed salt channel is divided by the secondary distribution plate and falls into the feed mixing tank through four dropping channels.

[0033] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model.
