Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery processing, in particular to a full-automatic chili stalk cutting machine. Background Art

[0002] With the continuous expansion of the sales market of agricultural products and the increasing improvement of people's living standards, the secondary processing and sales of agricultural products have increasingly become the mainstream of the market. Especially in China, which is a large agricultural country, the export volume of agricultural products is increasing day by day. Before deep processing of chili peppers with handles, the chili stalks must be cut off. Patent Application No.: 201310724775.9 discloses a full-automatic stalk removing machine, which specifically discloses that it mainly includes a drum, a support frame, and a reducer. A number of uniformly distributed round holes are provided on the wall of the drum. The drum is horizontally arranged in the support frame. A blade closely attached to the outer wall of the drum is horizontally arranged on the support frame. The rear end of the blade is tightened by a spring and fixed on the support frame. The direction of the blade is opposite to the rotation direction of the drum. The blade is arranged at the lower left or lower right of the outer wall of the drum. The reducer is arranged on the support frame at one end of the drum.

[0003] Although the above full-automatic stalk removing machine can cut off the chili stalks, there will still be a small amount of chili peppers with bent stalks. Due to the too large angle of the bent stalks, the stalks of the chili peppers cannot protrude from the smaller round holes of the drum for cutting. Therefore, these chili peppers with bent stalks are mixed in the chili peppers after removing the stalks and are conveyed out from the outlet. Usually, these chili peppers with bent stalks need to be manually selected, and the bent stalks are cut off before the secondary stalk cutting process, which is not only time-consuming and laborious, but also has low efficiency and reduces the cutting rate of chili stalks.

[0016] The utility model has the following advantages:

[0017] 1. For this fully automatic chili stalk cutting machine, the optimal diameter of the sieve holes of the first rotary drum sieve is 5.1-5.3 mm, which is convenient for the chili with a bent stalk to be hooked onto the sieve holes of the first rotary drum sieve. The motor drives the first rotary drum sieve to rotate through the speed reducer, the power output shaft, the universal joint, the rotary drum sieve rotating shaft and the rotary drum sieve rotating shaft connecting disc. Through the high-speed rotation of the rotary drum sieve, the chili with a bent stalk in the rotary drum sieve, under the action of centrifugal force, makes the heavier end with a handle face outward and has the opportunity to be inserted into the sieve holes of the first rotary drum sieve and hooked onto the first rotary drum sieve. The blade of the first rotary drum sieve closely attached to the top of the outer wall of the first rotary drum sieve, and the resistance of the blade cooperates with the round holes, and the bent stalk of the chili will be smoothly cut off; the cutting of the bent stalk of the chili is realized, and the cutting clean rate of the chili stalk is improved.

[0018] 2. The optimal diameter of the second and third drum screen holes of the fully automatic pepper stem cutting machine is 4.1-4.3 mm. The motor drives the second and third drum screens to rotate through the reduction box, the power output shaft, the universal joint, the drum screen shaft, and the drum screen shaft connecting plate. The rotation of the pepper in the drum screen drives the pepper to move in the barrel through the friction of the inner wall of the drum screen on the pepper. The movement speed of the pepper is higher than the speed of the pepper sliding at the bottom, and lower than the centrifugal movement speed of the pepper, so that when the pepper moves to the top, it falls due to the action of gravity; when the pepper rolls and falls, the heavier end with the handle faces downward, and the pepper stems have a certain probability of being inserted and connected to the second and third drum screen holes to complete the direction fixation. While the pepper moves, the pepper stems extend out of the barrel due to the centrifugal force. There are blades on the outside of the drum screen that are close to the drum screen. The rotation of the drum screen generates shearing force to complete the stem cutting work, thereby further improving the cutting rate of the pepper stems.

[0019] 3. The outer circle of the supporting roller of the rotating support device of the drum screen of the fully automatic pepper cutting machine is rollingly connected with the outer circle support of the drum screen, and the side of the supporting roller is rollingly connected with the outer side surface of the drum screen retaining ring. The structural design prevents the axial movement and radial jump of the drum screen during rotation, thereby improving the stability of the whole machine.

[0020] 4. The power output shaft of the power device of this fully automatic pepper cutting machine is connected to the rotating shaft of the drum screen through a universal joint. This ensures that even if the drum is slightly worn out during long-term operation, it will not cause loud noise or damage to the equipment due to the misalignment between the rotating shaft of the drum and the power output shaft. This effectively protects the equipment and reduces the cost of repair and maintenance.

[0021] 5. The push flow plate set on the drum screen of this fully automatic pepper cutting machine not only pushes the peppers to turn over, but also pushes the peppers from the inlet end of the drum screen to the outlet of the drum screen.

[0022] 6. The feed ports of the first drum screen, the second drum screen and the third drum screen of the fully automatic pepper cutting machine are arranged to be tilted higher than the discharge port. When the peppers rotate and tumble with the drum screens, they can also run along the length direction of the drum screens toward the end with the discharge port.

[0023] 7. This fully automatic chili stem cutting machine has a first waste material blocking slide plate tilted forward and backward on the frame between the first drum screen and the second drum screen, and a second waste material blocking slide plate tilted forward and backward on the frame between the second drum screen and the third drum screen, which prevents the cut chili stems from falling into the drum screen below and slides the chili stems to one side of the frame for easy collection.

The first drum sieve 7 and the second drum sieve 4 rotate inside the frame through a drum sieve rotating support device 8; on the first drum sieve 7, there are a first drum sieve feed inlet, a first drum sieve discharge outlet 7.1, a first drum sieve screen hole 7.2, and a first drum sieve retaining ring 7.3.

The blades 6.1 of the first drum sieve 7 are arranged at the top of the first drum sieve 7, and the blades 6.1 of the second drum sieve 4 are arranged at the bottom of the second drum sieve 4. The orientation of the blades 6.1 is opposite to the rotation direction of the first drum sieve 7 and the second drum sieve 4; on the frame 2, there is a device 6 for making the blades 6.1 closely attached to the outer wall of the drum sieve; the feed inlets of the first drum sieve 7 and the second drum sieve 4 are inclined with the discharge outlets being higher; while the chili peppers are rotating and tumbling with the drum sieve, it is also convenient for them to run along the length direction of the drum sieve towards the end with the discharge outlet; at the ends of the first drum sieve 7 and the second drum sieve 4, there is a power device 3.

[0032] Preferably, the drum sieve rotating support device 8 includes a support lug 8.1 fixedly connected to the frame 2. On the support lug 8.1, there is a support roller shaft 8.3. A support roller 8.2 is rotatably connected to the support roller shaft 8.3.

The side of the support roller 8.2 is in rolling abutment with the outer side surface of the first drum sieve retaining ring 7.3 or the second drum sieve retaining ring 4.3. The structural design of the outer circle of the support roller being in supporting rolling connection with the outer circle of the drum sieve and the side of the support roller being in rolling abutment with the outer side surface of the drum sieve retaining ring prevents the axial displacement and radial jump of the drum sieve during rotation, improving the stability of the whole machine.

[0033] Preferably, the device 6 for making the blades closely attached to the outer wall of the drum sieve includes a vertical plate 6.4 fixedly connected to a vertical connecting rod 2.3. On the vertical plate 6.4, a triangular plate 6.3 is fixedly connected in an adjustable up and down manner. A blade support plate 6.2 is rotatably connected to the triangular plate 6.3. On the upper surface of the blade support plate 6.2, a blade 6.1 is fixedly connected in an adjustable up and down manner.

The control switch of the motor 3.1 is a forward and reverse switch. The structural design of the power output shaft being drivingly connected to the rotary drum sieve rotating shaft through a universal joint enables the rotary drum to effectively protect the equipment and reduce the maintenance cost, even if there is slight wear during long-term operation, and there will be no phenomena such as loud noise and equipment damage due to the non-concentricity between the rotary drum rotating shaft and the power output shaft.

[0035] Preferably, a plurality of flow pushing plates 11 are obliquely arranged on the inner circle of the first rotary drum sieve 7 and the second rotary drum sieve 4 with respect to the axis of the rotary drum sieve. While pushing the chili peppers to turn over, the chili peppers are also pushed from the inlet end of the rotary drum sieve to the outlet end of the rotary drum sieve.

[0036] Preferably, a first waste blocking slide plate 12 is obliquely arranged front and back on the frame between the first rotary drum sieve 7 and the second rotary drum sieve 4. While preventing the cut chili pepper stalks from falling into the lower rotary drum sieve, the chili pepper stalks are slid to one side of the frame, which is convenient for centralized collection.

[0037] Preferably, the inclination angle is 5 - 15°.

[0038] Preferably, a finished product discharge receiving hopper 10 is arranged on the frame below the outlet 4.1 of the second rotary drum sieve.

[0039] Working principle of this embodiment:

[0040] The chili peppers are fed into the first feed hopper 5 through the feeding device. The chili peppers fall from the first feed hopper 5 into the first rotary drum sieve 7. For the chili peppers with bent stalks, due to the too large angle of the bent stalks, the handles of the chili peppers cannot protrude from the smaller round sieve holes of the rotary drum sieve to be cut off. If the sieve holes of the rotary drum sieve are too large, the bent stalks of the chili peppers cannot be hooked to the sieve holes of the rotary drum sieve. Through repeated experiments, the optimal diameter of the sieve holes 7.2 of the first rotary drum sieve is 5.1 - 5.3 mm. The motor 3.1 drives the first rotary drum sieve 7 to rotate through the speed reducer 3.2, the power output shaft 3.3, the universal joint 3.4, the rotary drum sieve rotating shaft 3.7, and the rotary drum sieve rotating shaft connecting disk 3.6. Through the high-speed rotation of the rotary drum sieve, the chili peppers with bent stalks in the rotary drum sieve, under the action of centrifugal force, make the heavier end with the handle face outward and have the opportunity to insert into the sieve holes 7.2 of the first rotary drum sieve and be hooked to the first rotary drum sieve. The blade 6.1 on the top of the outer wall of the first rotary drum sieve 7, in cooperation with the resistance of the blade 6.1 and the round holes, will smoothly cut off the bent stalks of the chili peppers;

[0041] The chili peppers in the first drum sieve 7 roll and slide from the inlet end to the discharge opening 7.1 of the first drum sieve during the rotation of the drum sieve, and fall into the second drum sieve 4 through the second feed hopper 9. The diameter of the sieve holes of the second drum sieve is too small, and the straight handle of the chili pepper cannot protrude from the smaller circular sieve holes of the drum sieve for cutting. If the sieve holes of the drum sieve are too large, the straight handle of the chili pepper cannot be clamped to the sieve holes of the drum sieve. Through repeated experiments, the optimal diameter of the sieve holes of the second drum sieve is 4.1 - 4.3 mm. The motor 3.1 drives the second drum sieve 4 to rotate through the speed reducer 3.2, the power output shaft 3.3, the universal joint 3.4, the drum sieve rotating shaft 3.7, and the drum sieve rotating shaft connecting plate 3.6. The rotation of the chili peppers in the drum sieve drives the chili peppers to move in the barrel through the frictional force of the inner wall of the drum sieve on the chili peppers. The moving speed of the chili peppers is higher than the sliding speed of the chili peppers at the bottom and lower than the centrifugal movement speed of the chili peppers. When the chili peppers move to the top, they fall due to the action of gravity; when the chili peppers roll and fall, the heavier end with the handle faces downward, and there is a certain probability that the chili pepper handle is inserted and clamped into the sieve holes 4.2 of the second drum sieve to complete the direction fixation. While the chili peppers are moving, the chili pepper handles extend out of the drum due to the centrifugal force. There are blades closely attached to the outer wall of the drum sieve outside the drum sieve, and the rotation of the drum sieve generates a shearing force to complete the handle cutting work. The chili peppers in the second drum sieve 4 roll and slide from the inlet end to the discharge opening 4.1 of the second drum sieve during the rotation of the drum sieve, and fall into the finished product discharge receiving hopper 10 and are discharged.

[0042] Example 2: As shown in Figure 3-4 , 5, Example 2 is basically the same as Example 1, the difference is that: inside the frame below the second drum sieve 4, a third drum sieve 14 and a third feed hopper 13 are also stacked up and down. The third drum sieve 14 rotates in the frame 2 through the drum sieve rotating support device 8; a third drum sieve feed opening, a third drum sieve discharge opening 14.1, third drum sieve sieve holes 14.2, and a third drum sieve retaining ring 14.3 are provided on the third drum sieve 14. The third drum sieve feed opening is rotatably connected to the third feed hopper 13, and the diameter of the third drum sieve sieve holes is 4.1 - 4.3 mm; the second drum sieve discharge opening 4.1 corresponds to the third feed hopper 13; blades 6.1 closely attached to the outer wall of the drum are provided on the third drum sieve 14. The blades 6.1 of the third drum sieve 14 are arranged at the bottom of the third drum sieve 14, and the direction of the blades 6.1 is opposite to the rotation direction of the drum sieve; the feed opening of the third drum sieve 14 is inclined with the discharge opening at a higher position; while the chili peppers are rotating and rolling with the drum sieve, it is also convenient for them to move along the length direction of the drum sieve towards the end with the discharge opening; a power device 3 is provided at the end of the third drum sieve 14.

[0043] Preferably, the rotary support device 8 of the drum screen includes a support lug 8.1 fixedly connected to the frame 2. A support roller shaft 8.3 is arranged on the support lug 8.1. A support roller 8.2 is rotatably connected to the support roller shaft 8.3. The outer circle of the support roller 8.2 is in rolling support connection with the outer circle of the third drum screen 14. The side of the support roller 8.2 is in rolling abutment with the outer side of the third drum screen retaining ring 14.3.

[0044] Preferably, the power device 3 includes a motor 3.1 fixedly connected to the transverse connecting rod 2.2 and a drum screen rotating shaft 3.7 rotatably connected through a drum screen rotating shaft support seat 3.5. A drum screen rotating shaft connecting disc 3.6 is fixedly connected to the drum screen rotating shaft 3.7. The drum screen rotating shaft connecting disc 3.6 is fixedly connected to the end of the third drum screen 14. The motor 3.1 is in transmission connection with a speed reducer 3.2. The speed reducer 3.2 is provided with a power output shaft 3.3. The power output shaft 3.3 is in transmission connection with the drum screen rotating shaft 3.7 through a universal joint 3.4. The control switch of the motor 3.1 is for forward and reverse rotation.

[0045] Preferably, a plurality of flow pushing plates 11 are arranged on the inner circle of the third drum screen 14 obliquely with respect to the axis of the drum screen.

[0046] Preferably, a second waste retaining slide plate 15 is arranged on the frame 2 between the second drum screen 4 and the third drum screen 14, being inclined front and back.

[0047] Preferably, the inclination angle of the inclination is 5 - 15°.

[0048] Preferably, a finished product discharge receiving hopper 10 is arranged on the frame 2 below the discharge opening 14.1 of the third drum screen.

[0049] The working principle of this embodiment is as follows:

[0050] The chili peppers in the second drum sieve 4 roll and slide from the inlet end to the discharge opening 4.1 of the second drum sieve during the rotation of the drum sieve, and fall into the third drum sieve 14 through the third feed hopper 13. The diameter of the sieve holes of the third drum sieve is too small, and the straight handle of the chili pepper cannot protrude from the smaller round sieve holes of the drum sieve for cutting. If the sieve holes of the drum sieve are too large, the straight handle of the chili pepper cannot be clamped to the sieve holes of the drum sieve. Through repeated experiments, the optimal diameter of the sieve holes of the third drum sieve is 4.1 - 4.3 mm. The motor 3.1 drives the third drum sieve 14 to rotate through the speed reducer 3.2, the power output shaft 3.3, the universal joint 3.4, the drum sieve rotating shaft 3.7, and the drum sieve rotating shaft connecting plate 3.6. The rotation of the chili peppers in the drum sieve drives the chili peppers to move in the barrel through the frictional force of the inner wall of the drum sieve on the chili peppers. The moving speed of the chili peppers is higher than the sliding speed of the chili peppers at the bottom and lower than the centrifugal movement speed of the chili peppers. When the chili peppers move to the top, they fall due to the action of gravity; when the chili peppers roll and fall, the heavier end with the handle faces downward, and there is a certain probability that the chili pepper handle is inserted and clamped into the sieve holes 14.2 of the third drum sieve to complete the direction fixing. While the chili peppers are moving, the chili pepper handles extend out of the barrel due to the centrifugal force. There are blades closely attached to the drum sieve outside the drum sieve, and the rotation of the drum sieve generates a shearing force to complete the handle cutting work. The chili peppers in the third drum sieve 14 roll and slide from the inlet end to the discharge opening 14.1 of the third drum sieve during the rotation of the drum sieve, and fall into the finished product discharge receiving hopper 10 and are discharged.
