Description

Technical Field

[0001] The utility model relates to the technical field of feed drying, in particular to feed drying equipment. Background Art

[0002] Feed is the general term for food for animals raised by humans. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten types of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, feed additives, etc.

[0003] After the feed is produced, it is relatively moist inside, so in order to facilitate subsequent bagging, the feed needs to be dried. The current drying method directly pours the feed into the dryer through the hopper for drying. Since the moist feed easily condenses into lumps, the subsequent drying in the dryer is uneven, which in turn affects the subsequent drying effect. Utility Model Content

[0004] The purpose of the utility model is to provide a feed drying device to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a feed drying device, comprising a dryer body and a feed hopper body connected to the top thereof, and further comprising:

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 As shown, a feed drying device comprises a dryer body 1, the top of the dryer body 1 is connected to a hopper body 2, a screening plate 3 is arranged inside the hopper body 2, and rebound structures 16 are arranged at the front and rear sides of both sides of the top of the screening plate 3, a rotating rod 4 is rotatably connected to the inner wall of the hopper body 2 below the screening plate 3, and a cam 5 is fixedly connected to the front and rear sides of the surface of the rotating rod 4, and rollers 6 are fixedly connected to the front and rear sides of the bottom of the screening plate 3, and the bottom surface of the roller 6 is in contact with one end surface of the cam 5, so that the friction between the cam 5 and the screening plate 3 during rotation can be reduced. In order to facilitate better application of force to the screening plate 3, a reciprocating screw 7 is rotatably connected to the inner wall of the hopper body 2 on the right side above the screening plate 3, and a driving structure 15 for driving the rotating rod 4 and the reciprocating screw 7 to rotate is provided on the surface of the hopper body 2, and a screw sleeve 8 is threadedly connected to the surface of the reciprocating screw 7, and a connecting plate 9 is fixedly connected to the bottom of the screw sleeve 8, and a plurality of fixed tubes 10 are fixed to the bottom of the connecting plate 9, and a push rod 11 is movably connected to the inside of the fixed tube 10, and a first spring 12 is fixedly connected to the inner wall of the fixed tube 10, and the other end of the first spring 12 is fixed to the top of the push rod 11.

[0024] The driving structure 15 includes a motor 151, a driving wheel 152 and a driven wheel 153. The motor 151 is fixed on the surface of the hopper body 2. The output shaft of the motor 151 is fixed to one end of the rotating rod 4. The interior of the driving wheel 152 is fixed to the front end surface of the rotating rod 4. The driving wheel 152 is connected to the driven wheel 153 through a belt. The interior of the driven wheel 153 is fixed to the front end of the reciprocating screw 7. In this way, when driving the rotating rod 4 and the reciprocating screw 7 to rotate, the motor 151 can be started, and the driving wheel 152 can be driven to rotate, and the driven wheel 153 can be driven to rotate at the same time, thereby driving the rotating rod 4 and the reciprocating screw 7 to rotate.

[0025] The rebound structure 16 includes a fixed plate 161, a movable rod 162 and a second spring 163. The fixed plate 161 is fixed at the corner of the inner wall of the hopper body 2. The surface of the movable rod 162 is movably connected to the inside of the fixed plate 161. The bottom end of the movable rod 162 is fixed to the top of the screening plate 3. The second spring 163 is sleeved on the surface of the movable rod 162. The two ends of the second spring 163 are respectively fixed between the fixed plate 161 and the top of the screening plate 3. In this way, as the screening plate 3 is pushed, the movable rod 162 will be driven to move inside the fixed plate 161. During the movement, the second spring 163 will be squeezed. When the screening plate 3 is not subjected to force, the second spring 163 can drive the screening plate 3 back to the starting position through its own elastic force.

[0026] A slide bar 17 is fixedly connected to the left side of the hopper body 2, and a slide sleeve 18 is movably connected to the surface of the slide bar 17. The bottom of the slide sleeve 18 is fixed to the top of the connecting plate 9, so that the connecting plate 9 can be auxiliary limited to facilitate its forward and backward movement.

[0027] Guide plates 19 are fixedly connected to both sides of the inner cavity of the hopper body 2. The guide plates 19 are arranged at an angle, so that the falling feed can be shielded, thereby facilitating the subsequent screening work.

[0028] Slide blocks 14 are fixedly connected to both sides of one end of the push rod 11, and slide grooves 13 are opened on both sides of the inner wall of the fixed tube 10. The surface of the slide block 14 is slidably connected to the inside of the slide groove 13, so that the push rod 11 can be auxiliary limited to prevent it from sliding out of the fixed tube 10.

[0029] It is worth noting that: the technical features proposed in this technical solution should be regarded as prior art, and the specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and this technical solution will not be further elaborated.

[0030] Working principle: When in use, the feed can be poured into the interior of the hopper body 2 and fall on the top surface of the screening plate 3. The feed that meets the size will continue to fall downward. At the same time, the driving structure 15 drives the rotating rod 4 to rotate, and drives the protruding part of the cam 5 to rotate upward, thereby applying force to the screening plate 3 upward. When the screening plate 3 is pushed upward, the second spring 163 will be squeezed. When the cam 5 rotates to the starting position, the second spring 163 at this time will use its own elastic force to drive the screening plate 3 back to the starting position. With the drive of the driving structure 15, the reciprocating screw 7 will also be driven to rotate, and the screw sleeve 8 and the connecting plate 9 will be driven to reciprocate back and forth, so that the push rod 11 can flatten and break up the piled-up feed and the solidified feed. This not only increases the plastic rate of the falling material, but also improves the subsequent drying effect.
