Description

Technical Field

[0001] The invention relates to the technical field of agriculture, and in particular to a stem and leaf separator capable of automated operation and large processing capacity. Background Art

[0002] Pineapple is one of the important economic fruit trees in Taiwan, China. After pineapple is harvested, the residues such as leaves, stems and fruit stalks left are 3 times more than pineapple fruits, and the remaining residues form a large amount of crop waste. At present, the remaining stems, leaves and fruit stalks are mainly left in the field by mechanical crushing, buried as garbage or incinerated for subsequent treatment. The disadvantages of this treatment method include slow decomposition speed and large amounts of carbon emissions during combustion, causing environmental pollution and waste of resources. Studies have found that the stem of pineapple is the part with the highest content of bromelain. Most of the bromelain currently on the market is extracted from the stem of pineapple, and can be made into natural fiber raw materials for use as environmentally friendly natural fiber fabrics, home decoration fabrics, packaging bags, etc., to achieve the effect of waste recycling and value enhancement, and reduce costs.

[0003] In the past, in order to effectively separate the stems and leaves of pineapples, workers were hired to manually separate the stems and leaves. This method has extremely poor work efficiency and high labor costs. In addition, the stems and leaves must be transported to the work site, which increases transportation costs and occupies a large amount of work space and storage space, making it difficult to achieve optimal efficiency.

[0004] Therefore, there is a new patent case of "leaf stripping machine" No. M481613 announced by Taiwan, China on July 11, 2014. It discloses: a base frame; a hydraulic fixing clamp assembly, which includes a hydraulic cylinder, which is arranged on one end of the base frame; a plurality of connecting rods, which are arranged on the hydraulic cylinder, and each connecting rod has an arc structure at the end; and a first hydraulic hinge, which is arranged on the hydraulic cylinder and between the connecting rods; and a hydraulic push rod assembly, which includes a hydraulic groove, which is arranged on the other end of the base frame; a second hydraulic hinge, which is on the hydraulic groove; and a leaf stripping structure, which is arranged on the hydraulic hinge.

[0005] The patent prior art still requires manual single-machine operation and can only process the stems and leaves of one pineapple at a time. Therefore, the processing time is long and it is difficult to improve work efficiency. Therefore, it is still not ideal in use. Summary of the invention

[0006] Therefore, in view of the above-mentioned shortcomings in the current separation operation of pineapple stems and leaves.

As the conveying unit passes through the front section of the working area, the sleeve will pass under the parallel rod, and the clamping part remains contracted and clamped. As the conveying unit passes through the rear section of the working area, the sleeve passes over the rising rod, and the sleeve will be pressed upward by the rising rod and move upward relative to the clamp, so that the clamping part expands and loosens; a tool unit is arranged in the working area, and the tool unit includes two power sources, two guide rail groups, two tool holders and two cutting knife seats. The two power sources and the two guide rail groups are relatively fixed in the working area. The two power sources drive the two tool holders to move up and down within the working area. The two cutting knife seats are affected by the two guide rail groups, so that the two cutting knife seats move relative to each other on the two tool holders, and the front ends of the two cutting knife seats are respectively provided with multiple blades.

[0007] Furthermore, the collecting area is arranged below the working area, and a cone-shaped opening is arranged between the collecting area and the working area.

[0008] Furthermore, a plurality of groups of the clamping units are provided, and the clamping units are fixed on the conveying unit at equal distances.

A stopper is fixed on the limit rod, and a spring is sleeved between the stopper and the stop plate. The stopper will press the spring to compress. A pulley is respectively provided at the positions of the two guide rails on both sides of the two cutter seats. As the two cutter seats descend, the pulley slides downward in the guide rail. The pulley moves to the gradually expanding section and is expanded by the gradually expanding section, so that the moving space of the two cutter seats becomes larger. Then, the elastic restoring force released after the spring is compressed makes the two cutter seats move relative to each other on the two tool holders.

DETAILED DESCRIPTION

[0038] See also Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present invention includes: a machine 1, a conveying unit 2, a clamping unit 3 and a tool unit 4, wherein: The machine 1 is formed with an inclined area 11, a working area 12 and a collecting area 13. The inclined area 11 is connected to the working area 12 in an inclined manner upward, and a pressing rod 111 is respectively provided at the lower part of both sides of the inclined area 11, and a parallel rod 121 is respectively provided at the lower part of both sides of the front section of the working area 12 corresponding to the two pressing rods 111, and a rising rod 122 is respectively provided at the lower part of both sides of the rear section of the working area 12 corresponding to the two parallel rods 121, and the front section height of the two rising rods 122 is lower than the rear section height of the two parallel rods 121 (such as Figure 4 The collecting area 13 is arranged below the working area 12, and a conical opening 131 is arranged between the collecting area 13 and the working area 12. The frame 1 is provided with a flat plate 123 above the working area 12.

[0039] The conveying unit 2 is disposed on the machine platform 1 and passes through the inclined area 11 and the working area 12. The conveying unit 2 is an annular conveying belt and is driven by an electric motor 21.

[0040] At least one clamping unit 3 is fixed to the conveying unit 2. In the embodiment of the present invention, multiple groups of the clamping units 3 are provided. The clamping units 3 are fixed to the conveying unit 2 at equal distances. The clamping unit 3 includes a clamp 31, a sleeve 32 and an adjusting screw 33 (such as Figure 5 and Figure 6). A rod 311 is provided above the clamp 31, and the rod 311 is fixed on the conveying unit 2. A plurality of jaws 312 that can be elastically opened by an elastic element 315 are separated below the rod 311. The jaws 312 are elastically expanded below the rod 311 to form a clamping portion 313. The sleeve 32 is sleeved on the outside of the clamp 31, and the sleeve 32 can move up and down relative to the outside of the clamp 31. When the sleeve 32 passes relatively through the outside of the jaws 312, the jaws 312 are contracted and clamped. A plurality of clamping teeth 314 are provided on the relative inner side surfaces of the jaws 312. The adjusting screw 33 is screwed into the top surface inside the clamping portion 313 of the clamp 31, so that the adjusting screw 33 can be rotated to change the depth dimension of the clamping portion 313. When the rod portion 311 passes through the inclined area 11 with the conveying unit 2, the sleeve 32 will pass under the lower pressing rods 111 on both sides of the inclined area 11, and when the inclined area 11 moves upward, the sleeve 32 will be pressed downward by the two lower pressing rods 111, so that the sleeve 32 gradually moves to the position of the clamping jaws 312, which will cause the clamping jaws 312 to contract and clamp (such as Figure 7 and Figure 8 As shown). When the rod 311 passes through the working area 12 along with the conveying unit 2, the sleeve 32 will pass under the parallel rods 121 on both sides of the front section of the working area 12, and the clamping jaws 312 will still remain contracted and clamped. When the rod 311 passes over the rising rods 122 on both sides of the rear section of the working area 12 along with the conveying unit 2, the sleeve 32 will be pushed upward by the two rising rods 122 and move upward. When the sleeve 32 gradually moves to the position of the rod 311, the clamping jaws 312 will expand and release.

[0041] The tool unit 4 is disposed in the working area 12. The tool unit 4 includes two power sources 41, two guide rail sets 42, two tool holders 43 and two cutting tool seats 44 (such as Fig. 9 , Fig.10 and Fig.11As shown). Two power sources 41 and two guide rail groups 42 are relatively fixed in the working area 12. The power source 41 is a hydraulic cylinder to drive a telescopic rod 411 to move up and down in the working area 12. Each group of the guide rail group 42 includes two guide plates 421 relatively fixed on both sides of the power source 41, and a guide rail 422 is respectively provided on the opposite inner sides of the two guide plates 421. A gradually expanding section 423 is provided below the guide rail 422, and an anti-return baffle 424 is provided below the gradually expanding section 423. Two tool holders 43 are respectively fixed on the telescopic rod 411, and the two tool holders 43 are respectively provided with two guide rods 431 extending outside the flat plate 123 of the frame 1, and can be driven by the lifting and lowering of the telescopic rod 411, so that the two tool holders 43 can move up and down within the working area 12 within a limited position. A limiting rod 441 of the two cutter seats 44 is respectively sleeved on a stop plate 432 of the two knife holders 43, and a stop block 442 is fixed on the limiting rod 441. A spring 443 is sleeved between the stop block 442 and the stop plate 432, and the stop block 442 will compress the spring 443. A pulley 444 is respectively provided at the positions corresponding to the two guide rails 422 on both sides of the two cutter seats 44. The pulley 444 has the function of sliding downward in the guide rail 422 as the two cutter seats 44 descend. When the pulley 444 moves to the gradually expanding section 423, it is expanded by the gradually expanding section 423, so that the movable space of the two cutter seats 44 becomes larger, and then the elastic restoring force released after the spring 443 is compressed can make the two cutter seats 44 move relative to each other on the two knife holders 43. The front ends of the two cutting blade seats 44 are respectively provided with a plurality of cutting edges 445 .

[0042] When using, please refer to Figure 1 , Fig. 9 and Fig.12 As shown, a pineapple stem A to be separated from the stem and leaves can be placed into the clamping portion 313 of the clamping member 31 of the clamping unit 3 (as shown in FIG. Fig.13As shown in the figure, the adjusting screw 33 can be rotated in advance according to the length of the pineapple stem A to be placed, so as to adjust the depth of the clamping part 313, so as to accommodate different lengths of the pineapple stem A. Then the conveying unit 2 is started to start the circulation operation. When the conveying unit 2 moves the clamping unit 3 loaded with the pineapple stem A to the inclined area 11, the sleeve 32 will pass under the lower pressing rods 111 on both sides of the inclined area 11, and as the inclined area 11 moves upward, the sleeve 32 will be pressed by the two lower pressing rods 111 and move downward, so that the sleeve 32 gradually moves to the position of the clamping jaws 312, which will cause the clamping jaws 312 to contract and clamp the pineapple stem A. When the sleeve 32 passes through the working area 12 along with the conveying unit 2, the sleeve 32 abuts against the lower side of the parallel rods 121 on both sides of the front section of the working area 12 and enters the working area 12, and the clamping jaws 312 still remain contracted to clamp the pineapple stem A (such as Fig.14 as shown).

[0043] At this time, the two power sources 41 respectively drive the telescopic rod 411 to retract downward, and the two knife holders 43 are respectively driven by the telescopic rod 411, and synchronously drive the two cutting knife seats 44 to move downward in the working area 12 (such as Fig.15 The pulleys 444 on both sides of the two cutter seats 44 will move downward as the two cutter seats 44 move downward (as shown). Fig.16 As shown in the figure, the two cutter seats 44 can slide downward in the guide rail 422. When the pulley 444 moves to the gradually expanding section 423, the movable space of the two cutter seats 44 becomes larger. By means of the elastic restoring force released after the spring 443 is compressed, the two cutter seats 44 can move relative to each other on the two knife holders 43. The blades 445 of the two knife holders 43 are clamped on the outer edge of the pineapple stem A. At the same time, the telescopic rod 411 is continuously retracted downward, and the blades can cut off the leaves on the outer edge of the pineapple stem A. The cut leaves will fall into the collection area 13 through the opening 131 and be collected. When the pineapple stem A with a larger outer diameter is clamped, the stopper 442 of the two cutter seats 44 can press the spring 443 on the limit rod 441 to compress it, so as to offset the reaction force generated by the pineapple stem A with a larger outer diameter, so as to avoid damage to the blade 445. In the process of moving downward to cut leaves, when the two cutting seats 44 encounter the part of the pineapple stem A with a larger diameter, the two cutting seats 44 move backwards relative to each other, so that the stopper 442 compresses the spring 443, and at the same time utilizes the blocking effect of the anti-return baffle 424 to prevent the pulley 444 from retreating excessively. Fig. 9 and Fig.11As shown, at the same time, the two power sources 41 drive the telescopic rod 411 to extend, and the two knife holders 43 are driven by the telescopic rod 411 respectively, and synchronously drive the two cutter seats 44 to move upward in the working area 12. The pulleys 444 on both sides of the two cutter seats 44 will slide upward with the two cutter seats 44, and move from the gradually expanding section 423 to the slide rail 422 (please refer to Fig.16 As shown in the figure), when the pulley 444 moves into the guide rail 422, the movable space of the two cutter seats 44 becomes smaller, so the stopper 442 will press the spring 443 to compress it, so that the spring 443 accumulates elastic force after being compressed. At the same time, the two cutter seats 44 move relative to each other in opposite directions on the two tool holders 43 to wait for the next blade cutting operation.

[0044] like Fig.17 As shown, the conveying unit 2 starts to operate, and the conveying unit 2 continues to circulate and convey the clamping unit 3 of the pineapple stem A with the leaves cut off. When the sleeve 32 passes over the rising rods 122 on both sides of the rear section of the working area 12 along with the conveying unit 2, the sleeve 32 is pushed upward by the two rising rods 122 and moves upward. When the sleeve 32 gradually moves to the position of the rod part 311, the clamping claw 312 is completely expanded and loosened, so that the pineapple stem A with the leaves cut off falls and is collected separately.

[0045] The machine platform of the stem-leaf separator of the embodiment of the present invention can be pivotally mounted on a transport vehicle to facilitate the transport to the pineapple field for direct leaf removal. At the same time, since the stem-leaf separator is pivotally mounted on the transport vehicle, it can rotate 360 ​​degrees to accommodate the feeding operation of pineapple stems in any direction, thereby achieving optimal maneuverability, reducing manual operation, and reducing the operating space and storage space to improve operating efficiency.

[0046] Based on the description of the above embodiments, the operation, use and effects of the present invention can be fully understood. The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of implementation of the present invention. That is, simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the invention description are all within the scope of the present invention.
