Description

Technical Field

[0001] The invention relates to the technical field of material lifting, in particular to a material lifting device for feed production. Background Art

[0002] Feed industry is a new industry in my country. The development of feed industry has greatly increased the development speed of breeding industry. The development of feed industry is also an important element of specialization and refinement of breeding industry. According to the level of meeting animal nutritional needs, feed products can be divided into complete feed, concentrated feed and premixed feed. The process of feed production and transportation requires the use of bucket elevators to transport feed.

[0003] Bucket elevator is a continuous conveying machine that uses a series of buckets evenly fixed on an endless traction member to lift materials vertically. Bucket elevator uses a series of buckets fixed on a traction chain or belt to transport bulk materials upward in a vertical or nearly vertical direction. It has the advantages of simple structure, low maintenance cost, high conveying efficiency, high lifting height, stable operation and wide application range.

Summary of the invention

[0042] like Figures 1 to 7As shown, a material lifting device for feed production provided by an embodiment of the present invention is used to lift materials for feed production; in this embodiment, the material lifting device for feed production includes a shell 100, a synchronous belt 300, a hopper 400 and a smoothing mechanism, a conveying cavity for transporting materials is formed inside the shell 100, a feed inlet 110 is arranged on one side of the bottom of the shell 100, and a discharge port 120 is arranged on the top of the shell 100 and on the side opposite to the feed inlet 110, and the conveying cavity is connected with the feed inlet 110 and the discharge port 120; the synchronous belt 300 is arranged inside the shell 100, and the synchronous belt 300 forms a closed conveying loop in the conveying cavity; there are multiple hoppers 400, and the multiple hoppers 400 are evenly spaced and arranged on the synchronous belt 300, and the hoppers 400 are used to receive materials from the feed inlet 110 and discharge the materials The material is thrown out from the discharge port 120 to a specified height; a smoothing mechanism is arranged on the hopper 400, and the smoothing mechanism is used to smooth the material in the hopper 400. In the present embodiment, the smoothing mechanism can be arranged to include a first driving cylinder and a push plate, the first driving cylinder is fixedly connected to the hopper 400 by bolts, and the push plate is arranged on the output shaft of the first driving cylinder; when in use, the material is put into the hopper 400 from the feed port 110, and when the hopper 400 is full of material, the first driving cylinder drives the push plate to move to smooth the material in the hopper 400, thereby reducing or avoiding abnormal accumulation of material in the hopper 400, and preventing the vibration generated during transportation of the hopper 400 from shaking the material off and causing waste, and then the hopper 400 is driven by the synchronous belt 300 to throw the material from the discharge port 120 to a specified height, so as to facilitate the subsequent process.

[0043] It can be understood that the first driving cylinder can be configured as any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0044] In some embodiments, Figure 5 and Figure 6 As shown, the smoothing mechanism can also be configured to include a spiral rod 430 and a trowel plate 410. The spiral rod 430 can be rotatably set on the hopper 400; the trowel plate 410 can be slidably sleeved on the spiral rod 430 along the length direction of the hopper 400, and the trowel plate 410 and the spiral rod 430 are spirally matched. The trowel plate 410 is used to smooth the material in the hopper 400.

[0045] Specifically, a connecting hole 450 is provided at one end of the hopper 400, and a trowel plate 410 is provided at the other end. A first through hole 411 is provided on the trowel plate 410. The spiral rod 430 passes through the first through hole 411 and the connecting hole 450 to determine the position. A spiral groove (not marked in the figure) is provided on the spiral rod 430. The trowel plate 410 is provided with a matching block (not marked in the figure) that matches the spiral groove at the first through hole 411. After the hopper 400 receives the material, the material in the hopper 400 is accumulated in a cone shape. This accumulation can easily cause the material to be shaken off due to vibration during the lifting process. Therefore, the trowel plate 410 is used to smooth the surface of the conically accumulated material to reduce the probability of the material being shaken off due to the vibration of the device.

[0046] In a further embodiment, Figure 5 , Figure 6 and Figure 7 As shown, a fourth groove 480 is provided on the hopper 400, and a baffle 420 is arranged in the fourth groove 480. The baffle 420 is connected to the hopper 400 through a first elastic member, and the first elastic member is used to reset the baffle 420; a matching groove 422 is provided on the baffle 420, and a matching piece 412 is provided on the trowel plate 410. The matching piece 412 cooperates with the matching groove 422 so that the trowel plate 410 and the baffle 420 move synchronously.

[0047] Specifically, when the trowel plate 410 is smoothed forward, it slides to the baffle plate 420, and the fitting piece 412 cooperates with the fitting groove 422 to connect the trowel plate 410 and the baffle plate 420 together, and the trowel plate 410 and the baffle plate 420 move synchronously. The trowel plate 410 is provided with an inclined plate 413 for smoothing materials. When the trowel plate 410 is connected with the baffle plate 420, there is a certain gap between the inclined plate 413 and the baffle plate 420, and some materials that are not smoothed during the forward smoothing process are accumulated in the gap. As the baffle plate 420 slides in the reverse direction following the trowel plate 410, the materials that are not smoothed during the forward smoothing fall from the gap and fill the pits in the forward smoothing process, completing the reverse smoothing operation.

[0048] More specifically, the first elastic member is a spring, which always resets or has a tendency to reset the baffle 420. When the baffle 420 slides in the reverse direction with the trowel plate 410, the spring is stretched, and when the trowel plate 410 slides in the reverse direction to the initial position, the tension generated by the spring overcomes the binding force between the matching piece 412 and the matching groove 422, so that the matching piece 412 is separated from the matching groove 422, and the baffle 420 is pulled back into the fourth groove 480.

[0049] To facilitate the leveling work of the trowel plate 410 and the baffle plate 420, a slide rail 460 is provided on the hopper 400, a slide groove 421 is provided on the baffle plate 420, and a slide groove (not marked in the figure) is also provided on the trowel plate 410. The trowel plate 410 and the baffle plate 420 slide along the slide rail 460 to perform the leveling operation.

[0050] In a further embodiment, a buffer pad is provided on a side of the baffle plate 420 away from the trowel plate 410 to prevent the baffle plate 420 from being damaged due to collision when being pulled back into the fourth groove 480 .

[0051] In some embodiments, Figure 5 As shown, the smoothing mechanism also includes a first driving member, which is used to provide driving force for the rotation of the screw rod 430. In this embodiment, the first driving member is a second motor 312, and the second motor 312 is fixedly connected to the hopper 400 by bolts. The second motor 312 drives the screw rod 430 to rotate through a belt.

[0052] In some embodiments, Figure 2 and Figure 3 As shown, the material lifting device for feed production also includes an adjusting mechanism, which includes a sensing block 190. The sensing block 190 is located below the feed port 110. The sensing block 190 can change the size of the feed port 110 according to the weight change of the hopper 400, thereby reducing the feed port 110 when the weight of the hopper 400 is greater than a preset value.

[0053] Specifically, the adjustment mechanism also includes a sliding block 150 and a connecting rod 160. The housing 100 is provided with a first groove 170 and a second groove 180. The sensing block 190 is slidably disposed in the first groove 170. The feed port 110 is communicated with the second groove 180. The sliding block 150 is slidably disposed in the second groove 180. The sliding block 150 is connected to the sensing block 190 through the connecting rod 160. When the sensing block 190 slides in the first groove 170, the sliding block 150 is driven to slide in the second groove 180 through the connecting rod 160 to change the feed port 110. 10 in size; a pressure sensor is provided at the connection between the hopper 400 and the synchronous belt 300. When there is no material in the hopper 400, the value of the pressure sensor is a preset value. When material is adhered to the hopper 400, the value of the pressure sensor is greater than the preset value. A second driving cylinder is also provided on the outer shell 100, and the output shaft of the second driving cylinder is connected to the sensing block 190. When material is adhered to the hopper 400, the value of the pressure sensor is greater than the preset value. The second driving cylinder drives the sliding block 150 to move through the sensing block 190 to reduce the feed port 110.

[0054] It can be understood that the second driving cylinder can be configured as any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0055] In the initial state, the sliding block 150 is in the second groove 180 and does not affect the feeding of the feed port 110. After the sensing block 190 drives the sliding block 150 to slide, the sliding block 150 partially leaves the second groove 180 and enters the feed port 110 area to form a protrusion, blocking the feeding area and reducing the feeding speed of the hopper 400. That is, the greater the sliding distance of the sensing block 190 in the first groove 170, the larger the protrusion of the sliding block 150 blocking the feed port 110, and the lower the feeding speed of the hopper 400.

[0056] In a further embodiment, Figure 3 As shown, the hopper 400 can be slidably arranged on the synchronous belt 300 in a direction perpendicular to the synchronous belt 300; the adjustment mechanism also includes a second elastic member and a third elastic member, one end of the second elastic member is arranged on the housing 100, and the other end is arranged on the sensing block 190; one end of the third elastic member is arranged on the synchronous belt 300, and the other end is arranged on the hopper 400.

[0057] Specifically, in this embodiment, the second elastic member is the first compression spring 191, the third elastic member is the second compression spring 470, the sensing block 190 is slidably connected to the first groove 170 through the first compression spring 191, and the first compression spring 191 always resets the sensing block 190 or has a tendency to reset; a protrusion 440 is provided on the hopper 400, and a fixed block 310 is provided on the synchronous belt 300, and a third groove 311 and a second through hole 314 are provided on the fixed block 310, and the spiral rod 430 passes through the second through hole 314 to stabilize the connection relationship with the fixed block 310, and the protrusion 440 on the hopper 400 is slidably connected to the third groove 311 through the second compression spring 470, and the second compression spring 470 always resets the hopper 400 or has a tendency to reset.

[0058] In other embodiments, the bottom surface of the sensing block 190 is an inclined surface 192 , and the height of the inclined surface 192 gradually decreases from the inside to the outside of the housing 100 .

[0059] In some embodiments, Figure 1 and Figure 2 As shown, the material lifting device for feed production also includes a driving shaft 130 and a driven shaft 140. Both the driving shaft 130 and the driven shaft 140 are rotatably inserted into the housing 100, and the driving shaft 130 is located above the driven shaft 140; one end of the synchronous belt 300 is wound around the driving shaft 130, and the other end is wound around the driven shaft 140.

[0060] In a further embodiment, Figure 1As shown, the material lifting device for feed production also includes a second driving member, which is used to provide a driving force for the rotation of the driving shaft 130. In this embodiment, the second driving member is a first motor 200, and the first motor 200 is fixedly connected to the outer wall surface of the outer shell 100 by bolts. The first motor 200 drives the driving shaft 130 to rotate through a belt.

[0061] Specifically, the first motor 200 is started to make the driving shaft 130 rotate at a constant speed, and the driving shaft 130 drives the synchronous belt 300 and the driven shaft 140 to rotate at a constant speed, so that the fixed block 310 on the synchronous belt 300 moves at a constant speed, and the hopper 400 connected to the fixed block 310 also moves at a constant speed. In the initial state, a part of the induction block 190 is outside the first groove 170, and the hopper 400 contacts the inclined surface 192 on the induction block 190 during the process of being lifted at a constant speed, and the hopper 400 and the induction block 190 slide against each other, that is, the hopper 400 pushes the induction block 190 to slide in the first groove 170.

[0062] The more materials adhered to the hopper 400, the greater the weight of the hopper 400, and the greater the friction generated by the sliding of the hopper 400 in the third groove 311. The hopper 400 contacts the sensing block 190, and the hopper 400 and the sensing block 190 slide against each other. That is, the hopper 400 slides in the third groove 311, generating friction while compressing the second compression spring 470; the sensing block 190 slides in the first groove 170, compressing the first compression spring 191, and when the elastic force generated by the first compression spring 191 is equal to the elastic force generated by the second compression spring 470 and the friction generated by the sliding of the hopper 400, the hopper 400 and the sensing block 190 are balanced. When the weight of the hopper 400 is large, the friction force generated by the sliding of the hopper 400 is also large, and the elastic force generated by the first compression spring 191 when in balance is also greater, that is, the greater the amount of compression of the first compression spring 191, the greater the sliding distance of the sensing block 190, the greater the sliding distance of the sliding block 150, the smaller the opening of the feed port 110, and the less the amount of material entering the hopper 400 per unit time.

[0063] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows:

[0064] The first motor 200 is started to rotate the driving shaft 130 at a constant speed, and the driving shaft 130 drives the driven shaft 140 to rotate at a constant speed, so that the hopper 400 on the synchronous belt 300 moves at a constant speed, and each hopper 400 has the same feeding time. The material enters from the feed port 110 and falls into the hopper 400, and the rate at which the material is fed into the feed port 110 is set to a constant rate.

[0065] Before the hopper 400 moves to the feed port 110, the hopper 400 will first contact the sensing block 190. In the initial state, if the sensing block 190 is not in contact with the hopper 400, the sensing block 190 extends out of the first groove 170, and the sensing block 190 is connected to the first groove 170 through the first compression spring 191. At this time, the sliding block 150 is entirely in the second groove 180, and does not affect the feeding speed of the feed port 110. When the sensing block 190 contacts the unloaded hopper 400, the hopper 400 moves upward along the inclined surface 192 of the sensing block 190. Under the obstruction of the sensing block 190, the hopper 400 slides in the third groove 311, compressing the second compression spring 470, and at the same time, friction is generated between the protrusion 440 and the bottom plate 313. Under the action of the friction between the second compression spring 470 and the protrusion 440 and the bottom plate 313, the hopper 400 pushes the sensing block 190 to slide a certain distance into the first groove 170. The sensing block 190 drives the sliding block 150 to slide a certain distance through the connecting rod 160, so that the sliding block 150 extends a part of the second groove 180 into the feeding channel, affecting the feeding area and reducing part of the feeding speed. The material falls into the hopper 400 at this feeding speed. When the hopper 400 leaves the feeding port 110, the material in the hopper 400 just reaches the maximum capacity of the hopper 400. At this time, under the action of the first compression spring 191, the sensing block 190 is reset.

[0066] When some material adheres to the hopper 400, the overall weight of the hopper 400 increases, so that when the hopper 400 slides in the third groove 311, the friction between the protrusion 440 and the bottom plate 313 increases. At this time, when the hopper 400 passes through the sensing block 190, it will push the sensing block 190 to slide a further distance into the first groove 170, so that the sliding block 150 forms a protrusion in the feed channel to block the feed area of ​​the feed channel, further reducing the feed speed of the material. In the same period of time, the amount of material falling into the hopper 400 decreases, but with the material previously adhered to the hopper 400, the material in the hopper 400 can just reach the fluctuation range of the maximum capacity of the hopper 400. According to the degree of material adhesion in the hopper 400, the sensing block 190 is pushed to slide a corresponding distance, so that the sliding block 150 forms a protrusion in the feeding channel, thereby changing the feeding speed of the material to adapt to the material adhered in the hopper 400, so that after each hopper 400 completes the feeding, the material in the hopper 400 is within the fluctuation range of the maximum capacity of the hopper 400.

[0067] After the hopper 400 leaves the feed port 110, the materials in the hopper 400 are accumulated in a cone shape. At this time, the second motor 312 is started, driving the screw rod 430 to rotate forward, and the screw rod 430 cooperates with the spiral groove of the trowel plate 410. The forward rotation of the screw rod 430 drives the trowel plate 410 to slide along the slide rail 460 toward the baffle 420. During the sliding process, the inclined plate 413 smoothes the materials in the hopper 400 in the forward direction until the trowel plate 410 slides to the baffle 420, and the matching piece 412 on the trowel plate 410 cooperates with the matching groove 422 on the baffle 420, so that the trowel plate 410 is connected to the baffle 420. There is a certain gap between the inclined plate 413 and the baffle 420, and some materials that are not smoothed in the forward smoothing process are accumulated in the gap. Then the second motor 312 drives the screw rod 430 to reverse, the screw rod 430 drives the trowel plate 410 to slide in the reverse direction, and the trowel plate 410 drives the baffle plate 420 to slide in the reverse direction along the slide rail 460, and the third elastic member connected between the baffle plate 420 and the fourth groove 480 is stretched. During the reverse sliding process, the material that has not been smoothed in the forward direction falls from the gap and fills the pit in the forward smoothing process, completing the reverse smoothing operation. When the trowel plate 410 slides in the reverse direction to the initial position, the tension generated by the third elastic member overcomes the binding force between the matching member 412 and the matching groove 422, and pulls the baffle plate 420 back into the fourth groove 480. A buffer is provided in the fourth groove 480 to prevent the baffle plate 420 from being damaged due to collision when being pulled back into the fourth groove 480. At this time, the material in the hopper 400 has been smoothed, and the material will not fall due to shaking during the lifting process, and the material in the hopper 400 is within the fluctuation range of the maximum capacity of the hopper 400. As the hopper 400 is moved to the top, the materials in the hopper 400 are discharged at the discharge port 120 under the action of centrifugal force and inertia.
