DETAILED DESCRIPTION
[0036] In the prior art, when picking Sichuan pepper, a feeding and cutting method is usually adopted, that is, the picking device is close to Sichuan pepper, and Sichuan pepper is made to enter the picking device by relative movement, and then Sichuan pepper is cut off by the cutting structure inside the picking device. In this way, the tender bud at the connection between the Sichuan pepper fruit and the Sichuan pepper tree is easy to enter the picking device and be cut off together. The present application changes the feeding and cutting method to rake cutting, and after the Sichuan pepper fruit and Sichuan pepper branch are raked in, a blocking barrier is formed at the entrance of the picker, which blocks the tender bud at the connection between the subsequent Sichuan pepper fruit and Sichuan pepper tree from entering the picker or the cutting area, so that the tender bud at the connection between the Sichuan pepper fruit and the Sichuan pepper tree is not damaged. In order to realize the above picking method, as shown in the figure, the present application comprises a housing 1, a boss 2, a rake 3, a side plate 4, a motor 5, a collection port 6, a cutter 7, a battery 8, a button switch 9 and a speed regulator 10, and the structure, working principle and use method of the present application will be described in detail below with reference to the accompanying drawings. Figures 1 to 13
[0037] As shown in the figure, the Sichuan pepper picker for preventing damage to the tender bud comprises a housing 1, a battery 8 and a motor 5, the front wall of the housing 1 is open and the bottom of the housing 1 is open, the open front wall of the housing 1 forms an entrance for Sichuan pepper fruits or / and Sichuan pepper branches, and the open bottom of the housing 1 is a removal channel for cut Sichuan pepper fruits. The housing 1 of the present application is in the shape of an elongated square or a square, and the motor 5 and the battery 8 are both fixed on the housing 1, as shown in the figure, the housing 1 also has a button switch 9 electrically connected between the motor 5 and the battery 8. Figures 1 to 4 Figure 2
[0038] The present application adopts the combined structure of the rake 3, the cutter 7 and the boss 2 to solve the technical problem.
[0039] As shown in Figure 1 , Figure 3 , Figure 4 and Figure 5 , the output shaft 51 of the motor 5 extends into the shell 1 and is fixedly connected with the rake 3, as shown in Figure 13 , the rake 3 has at least one group of tines 32, each group of tines 32 is a plurality of tines arranged at equal intervals, the cutter 7 is slidingly arranged on the rake 3, and the sliding direction of the cutter 7 is parallel to the axial direction of the output shaft 51 of the motor 5. In the plane perpendicular to the output shaft 51, the cutter 7 is relatively fixed with the rake 3. As shown in Figure 10 , Figure 11 and Figure 13 , the cutter 7 has a blade 73, and the blade 73 has a plurality of cutting teeth 75 arranged at equal intervals. Each adjacent two tines 32 forms a V-shaped tooth gap 34, and each adjacent two cutting teeth 75 also forms a V-shaped tooth gap 34. The size and shape of the cutting tooth 75 and the tine 32 are completely the same, the blade 73 and the tine 32 are in close contact front and back, and then the cutting tooth 75 and the tine 32 are in close contact front and back. There are three relative position relationships between the cutting tooth 75 and the tine 32, that is, the cutting tooth 75 and the tine 32 are completely coincident, the cutting tooth 75 and the tine 32 are completely staggered, and the cutting tooth 75 and the tine 32 are partially coincident. When the cutting tooth 75 and the tine 32 are completely coincident, the tooth gap 34 between the tines 32 is completely exposed, and the pepper fruits and branches are easy to enter the tooth gap 34. When the cutting tooth 75 and the tine 32 are completely staggered, the tooth gap 34 is blocked to the maximum extent. When the cutting tooth 75 and the tine 32 are partially coincident, the tooth gap 34 is partially exposed and partially blocked.
[0040] As shown in Figure 1 , Figure 3 and Figure 4 , the boss 2 is fixed inside the shell 1, and there are two bosses 2, as shown in Figure 12 , the end of the boss 2 has an annular driving surface 21, as shown in Figure 13 , and the driving surfaces 21 on the two bosses 2 are arranged towards each other. The cutter 7 has a handle 71, and the handle 71 is located between the two bosses 2, and the end of the handle 71 always keeps in contact with the driving surface 21 on the corresponding side boss 2. When the rake 3 rotates, the pepper is raked into the shell 1 from the front side of the shell 1, the cutter 7 rotates with the rake 3 and reciprocates along the output shaft 51 under the cooperation of the driving surfaces 21 of the two bosses 2, so that the cutting tooth 75 and the tine 32 move relatively to realize the cutting of the pepper branches, and the cut pepper is removed from the bottom of the shell 1. As shown in Figure 10 , Figure 11As shown, the cutting knife 7 includes a handle 71, a connecting block 72 and a blade 73, and the handle 71 is in a cylindrical structure. The two ends of the handle 71 are rounded, which is beneficial to transmission and reduces friction. Specifically, the end of the handle 71 can be processed into a semispherical shape. The blade 73 is arranged in parallel with the handle 71, and the two are fixedly connected through the connecting block 72, so that the entire cutting knife 7 is in an integrated structure. The length of the blade 73 is less than the length of the main body of the rake 3, and the number of the cutting teeth 75 is less than the number of the rake teeth 32.
[0041] In the above combination structure, the function of the rake 3 is that the rotating rake 3 rakes the pepper fruits and branches at the entrance of the shell 1 into the shell 1, and the rotating rake 3 drives the rotation of the cutting knife 7. During the rotation of the cutting knife 7, the driving surface 21 on the two bosses 2 cooperates to drive the handle 71 to move axially along the output shaft, and during the reciprocating movement of the cutting knife 7 with the handle 71, the relative movement between the cutting teeth 75 and the rake teeth 32 is realized. The function of the boss 2 is to drive the reciprocating movement of the cutting knife 7 along the output shaft 51. While the cutting knife 7 rotates synchronously with the rake 3, the cutting knife 7 also moves linearly relative to the rake 3 under the action of the boss 2.
[0042] In order to realize the sliding connection between the cutting knife 7 and the rake 3, as shown in Figure 13 , the cutting knife 7 and the rake 3 are connected through three groups of sliding structures, which form a triangle, that is, the three groups of sliding structures are located at the three vertices of the triangle, and the sliding directions of the three groups of sliding structures are parallel to the output shaft 51 of the motor 5. The function of the three groups of sliding structures is that, on the one hand, the sliding connection between the cutting knife 7 and the rake 3 is realized through the three groups of sliding structures; on the other hand, the relative fixation of the cutting knife 7 and the rake 3 in the plane perpendicular to the output shaft 51 is realized by the principle of three-point coplanar, so as to ensure that the cutting knife 7 rotates synchronously with the rake 3.
[0043] Next, an embodiment of the sliding structure will be described: as shown in Figure 8 , Figure 9 and Figure 13 , a group of guide rails 31 are fixed on the rake 3, each group including two guide rails 31, and the connecting line of the two guide rails 31 is parallel to the output shaft 51 of the motor 5, as shown in Figure 13 , the handle 71 penetrates through the two guide rails 31 and is in sliding connection with the guide rails 31, and the handle 71 and the two guide rails 31 constitute the first and second groups of sliding structures. The rake 3 has a sliding groove 33, as shown in Figure 11 , the blade 71 has a guide block 74, as shown in Figure 13 , the guide block 74 extends into the sliding groove 33 and is in sliding connection with the sliding groove 33, and the sliding direction between the guide block 74 and the sliding groove 33 is also parallel to the output shaft 51 of the motor 5, and the guide block 74 and the sliding groove 33 constitute the third group of sliding structures.
[0044] To facilitate rake 3 in rakeing the pepper fruits and branches into the shell 1, such as Figure 8 , Figure 9 As shown, the rake teeth 32 are vertically aligned with the rake body 3. When the rake 3 is rotated to a horizontal position, the rake teeth 32 face downwards. Alternatively, the rake teeth 32 and the rake body 3 can be aligned at an obtuse angle. When the rake 3 is rotated to a horizontal position, the rake teeth 32 face downwards and forwards from the housing 1. Both angled alignments of the rake teeth 32 and the rake body 3 allow for the rake to collect the pepper fruits and branches into the housing 1. The vertical alignment of the rake teeth 32 and the rake body 3 is the preferred embodiment of this invention.
[0045] To improve harvesting efficiency, this invention designs two to four sets of rake teeth 32, with the teeth 32 located at the edge of the rake 3. Several sets of teeth 32 are evenly distributed on a circumference centered on the output shaft 51. Simultaneously, the number of cutting blades 7 is the same as the number of sets of teeth 32, and the cutting blades 7 are arranged in a one-to-one correspondence with the teeth 32. This corresponding arrangement of cutting blades 7 and teeth 32 works in conjunction to cut the pepper branches. When there are two sets of teeth 32, the rake 3 has a plate-like structure. When there are three sets of teeth 32, the rake 3 has a herringbone structure. When there are four sets of teeth 32, the rake 3 has a cross-shaped structure.
[0046] To ensure efficient harvesting of Sichuan peppercorns, and to facilitate the entry of the peppercorns and branches into the shell, such as... Figure 8 , Figure 9 As shown, in the preferred embodiment of the present invention, the rake teeth 32 are designed as two sets. In this case, the rake 3 is a rectangular plate-like structure, and the rake teeth 32 are arranged perpendicularly to the rake 3. Figure 8 , Figure 9 As shown, a set of guide rails 31 are provided on both sides of the rake 3, and a groove 33 is provided at the intersection of the rake teeth 32 and the main body of the rake 3. After the cutter 7 is assembled on the rake 3, when the handle 71 of the first cutter 7 contacts the low surface 23 of the left boss 2, the handle 71 of the second cutter 7 contacts the high surface 22 of the right boss 2. At this time, the blades 73 of the two cutters 7 overlap and are located in the middle of the rake 3. Otherwise, the blades 73 of the two cutters 7 are slightly to the left and slightly to the right.
[0047] To achieve the driving action of the cutter 7, such as Figure 12 As shown, the driving surface 21 includes a high surface 22, a low surface 23, and a transition surface located between the high surface 22 and the low surface 23. The high surface 22 and the low surface 23 on the same driving surface 21 are arranged at a 180-degree angle. Figure 13As shown, the high level surface 22 on the driving surface 21 of the first boss 2 is arranged in alignment with the low level surface 23 on the driving surface 21 of the second boss 2, and the low level surface 23 on the driving surface 21 of the first boss 2 is arranged in alignment with the high level surface 22 on the driving surface 21 of the second boss 2. In this way, when the first end of the tool shank 71 contacts the high level surface 22 on the first boss 2, the second end of the tool shank 71 contacts the low level surface 23 on the second boss 2. When the first end of the tool shank 71 contacts the low level surface 23 on the first boss 2, the second end of the tool shank 71 contacts the high level surface 22 on the second boss 2. When the first end of the tool shank 71 moves along the high level surface 22 on the first boss 2, the second end of the tool shank 71 moves along the low level surface 23 on the second boss 2, and at this time the tool shank 71 remains stationary and the left and right positions of the tool shank 71 do not change. When the first end of the tool shank 71 moves along the low level surface 23 on the first boss 2, the second end of the tool shank 71 moves along the high level surface 22 on the second boss 2, and at this time the tool shank 71 also remains stationary and the left and right positions of the tool shank 71 do not change.
[0048] When the first end of the tool shank 71 contacts the transition surface on the first boss 2, the second end of the tool shank 71 contacts the transition surface on the second boss 2. When the first end of the tool shank 71 moves uphill along the transition surface on the first boss 2, the second end of the tool shank 71 moves downhill along the transition surface on the second boss 2, and at this time the tool shank 71 moves to the side where the second boss 2 is located. When the first end of the tool shank 71 moves downhill along the transition surface on the first boss 2, the second end of the tool shank 71 moves uphill along the transition surface on the second boss 2, and at this time the tool shank 71 moves to the side where the first boss 2 is located. The high level surface 22 and the low level surface 23 are both designed as flat surfaces, and the transition surface is designed as a curved surface.
[0049] When the first end of the tool shank 71 contacts the high level surface 22 on the first boss 2 and the second end of the tool shank 71 contacts the low level surface 23 on the second boss 2, the cutter 7 moves to the right to the limit. When the first end of the tool shank 71 contacts the low level surface 23 on the first boss 2 and the second end of the tool shank 71 contacts the high level surface 22 on the second boss 2, the cutter 7 moves to the left to the limit. When the tines 32 are provided with two groups, the rake 3 has two cutters 7, as shown in Fig. 2. Figure 14As shown, when the first end of the handle 71 of the first cutter 7 moves along the high level surface of the first boss 2, the first cutter 7 keeps the right limit position; at this time, the first end of the handle 71 of the second cutter 7 moves along the low level surface of the first boss 2, and the second cutter 7 keeps the left limit position. When the first end of the handle 71 of the first cutter 7 moves down along the driving surface of the first boss 2, the first cutter 7 moves left; at this time, the first end of the handle 71 of the second cutter 7 moves up along the driving surface of the first boss 2, and the second cutter 7 moves right. When the first end of the handle 71 of the first cutter 7 moves along the low level surface of the first boss 2, the first cutter 7 moves left to the left limit position and keeps the left limit position; at this time, the first end of the handle 71 of the second cutter 7 moves along the high level surface of the first boss 2, and the second cutter 7 moves right to the right limit position and keeps the right limit position. When the first end of the handle 71 of the first cutter 7 moves up along the driving surface of the first boss 2, the first cutter 7 moves right; at this time, the first end of the handle 71 of the second cutter 7 moves down along the driving surface of the first boss 2, and the second cutter 7 moves left. When the cutter 7 rotates one circle along with the rake 3, the handle 71 of the cutter 7 rotates one circle along the driving surface of the boss 2, at this time, the cutter 7 reciprocates left and right once, which is one movement cycle of the cutter 7. Figure 14 In the present application, the midpoint between the left limit position of the first end of the handle 71 of the cutter 7 and the right limit position of the second end of the handle 71 of the cutter 7 is taken as the displacement origin, i.e. the coordinate system origin.
[0050] When two groups of tines 32 are arranged on the rake 3, the rake 3 rotates one circle, and the two groups of tines 32 pass through the entrance of the shell 1 in turn, and perform the action of raking in the pepper fruits and branches once. In order to facilitate the pepper fruits and branches to extend into the tooth gap 34 and pass through the tooth gap 34, the placement positions of the high level surface 22 and the low level surface 23 should be such that when the rake 3 is in a horizontal state and the tines 32 are in a vertical state, the tines 32 are completely overlapped, i.e. the tooth gap 34 is completely exposed. The structure of the boss 2 and its placement position make the moving directions of the two cutters 7 always opposite.
[0051] In order to facilitate the installation and maintenance of the rake 3 and the cutter 7, the shell 1 is provided with a plurality of installation holes 11, and the cutter 7 is provided with a plurality of installation holes 71. Figure 6As shown, the side hole 13 is arranged on the left or right side wall of the shell 1, and the side plate 4 is detachably mounted on the left or right side wall of the shell 1. The side plate 4 has the following functions: on the one hand, it seals the side hole 13; on the other hand, it assembles the motor 5 and the boss 2. Specifically: the first boss 2 is fixed on the inner wall of the side plate 4, and the second boss 2 is fixed on the right or left side wall of the shell 1 corresponding to the side plate 4. When the side hole 13 is arranged on the left side wall of the shell 1, the first boss 2 is fixed on the inner wall of the side plate 4, and the second boss 2 is fixed on the right side wall of the shell 1. When the side hole 13 is arranged on the right side wall of the shell 1, the first boss 2 is fixed on the inner wall of the side plate 4, and the second boss 2 is fixed on the left side wall of the shell 1. The motor 5 is fixed on the outer wall of the side plate 4, and the battery 8 is fixed on the side wall of the shell 1 corresponding to the side plate 4. The motor 5 and the battery 8 are arranged on the opposite side walls of the shell 1 to form counterweights, which are beneficial to balance. Figure 7 As shown, the side plate 4 is a rectangular plate, and the side plate 4 has a rectangular protrusion 41. The size of the protrusion 41 is the same as that of the side hole 13, and the protrusion 41 is used to extend into the side hole 13 to seal the side hole 13. The entire side plate 4 is provided with mounting holes. The mounting hole 41 at the position of the protrusion 41 is used to realize the assembly of the side plate 4 and the motor 5, and the mounting hole 41 outside the position of the protrusion 41 is used to realize the assembly of the side plate 4 and the shell 1.
[0052] For easy assembly, as shown, Figure 12 As shown, the boss 2 has a through hole 24 in the center, and the end of the output shaft 51 penetrates the through hole 24 corresponding to the boss 2, and the output shaft 51 is arranged concentrically with the through hole 24. The boss 24 is arranged concentrically with the output shaft 51, which further ensures that the tool handle 71 moves in a circular motion along the driving surface 21 of the boss 2.
[0053] For easy removal of the cut pepper fruits, as shown, Figure 1 As shown, the bottom of the shell 1 has a bottom hole 11. The arrangement of the bottom hole 11 makes the bottom of the shell 1 open. As shown, Figure 5 As shown, the rear wall of the shell 1 has an opening 14 communicating with the bottom hole 11, and the bottom hole 11 and the opening 14 jointly constitute a pepper outlet. After the tines 32 and the cutting teeth 75 cooperate to cut off the pepper branches, the rotary rake 3 throws the pepper fruits to the lower rear of the shell 1. The arrangement of the opening 14 is beneficial to the removal of the pepper fruits.
[0054] For further easy removal of the pepper fruits, as shown, Figures 2 to 5As shown, the bottom of the shell 1 has a front-to-back inclined transition part 12, the first end of the transition part 12 is fixedly connected with the shell 1 and connected with the Zanthoxylum bungeanum M. outlet, and the second end of the transition part 12 has a collection port 6. The inclination direction of the transition part 12 is the same as the throwing direction of the Zanthoxylum bungeanum M. by the rake 3, thereby ensuring the smooth removal of the Zanthoxylum bungeanum M.. The transition part 12 is a cylindrical structure or a conical structure; when the transition part 12 is a cylindrical structure, the diameter of the collection port 6 is smaller than the diameter of the transition part 12; when the transition part 12 is a conical structure, the diameter of the collection port 6 is the same as the small end diameter of the transition part 12. The collection port 6 is a transfer channel for the Zanthoxylum bungeanum M., and the collection port 6 is used for transferring the cut Zanthoxylum bungeanum M.. Meanwhile, the collection port 6 is also used for the hand holding of the operator, thereby hand holding the entire picker.
[0055] In order to adjust the rotating speed of the rake 3, the speed regulator 10 is further arranged on the shell 1, the speed regulator 10 is used for adjusting the rotating speed of the output shaft 51, thereby realizing the adjustment of the rotating speed of the rake 3. The rotating speed of the rake 3 determines the picking efficiency of the Zanthoxylum bungeanum M., and the rotating speed of the rake 3 should be appropriate. If the rotating speed of the rake 3 is too slow, the pulling effect on the Zanthoxylum bungeanum M. tree is large. If the rotating speed of the rake 3 is too fast, the Zanthoxylum bungeanum M. picked in one time is too small.
[0056] The working principle of the present application is described as follows: (1) the battery 8 supplies power for the motor 5, the rotation of the output shaft 51 of the motor 5 drives the rotation of the rake 3, the cutter 7 rotates synchronously when the rake 3 rotates, and the cutter handle 71 moves left and right in a straight line under the cooperation of the driving faces 21 of the two bosses 2. (2) When the rake 3 rotates to the inlet, the rake teeth 32 of the rake 3 coincide with the cutter teeth 75 of the cutter 7, and the tooth gap 34 is opened, so that the Zanthoxylum bungeanum M. and Zanthoxylum bungeanum M. branches can extend into the tooth gap and pass through the tooth gap, thereby forming a pulling effect on the Zanthoxylum bungeanum M.. In addition, the rake 3 forms a blocking barrier at the inlet, the Zanthoxylum bungeanum M. and Zanthoxylum bungeanum M. branches pass over the rake teeth 32 of the rake 3, and the tender buds at the connection between the Zanthoxylum bungeanum M. and the Zanthoxylum bungeanum M. tree are blocked by the rake teeth 32, preventing the tender buds at the connection between the Zanthoxylum bungeanum M. and the Zanthoxylum bungeanum M. tree from entering the cutting area. (3) When the rake teeth 32 move from the inlet of the shell 1 to the rear side of the shell 1, the rake teeth 32 and the cutter teeth 75 gradually disengage, the tooth gap 34 gradually narrows from the fully exposed state, and the rake teeth 32 and the cutter teeth 75 cooperate to cut the Zanthoxylum bungeanum M. branches. (4) After the Zanthoxylum bungeanum M. branches are cut, the Zanthoxylum bungeanum M. moves to the Zanthoxylum bungeanum M. outlet under the throwing action of the rotating rake 3, enters the transition part 12 and the collection port 6.
[0057] The use method of the present application is described as follows:
[0058] S1, press the button switch 9, start the motor 5, adjust the output shaft 51 rotating speed through the speed regulator 10. S2, hand-held collection port 6, move the shell 1 to the Zanthoxylum bungeanum fruit. The rotating rake 3 will Zanthoxylum bungeanum fruit into the shell 1, and cooperate with the cutting knife 7 to cut off the Zanthoxylum bungeanum branch, realize the picking of Zanthoxylum bungeanum fruit.
[0059] The present application is provided with a rake, the rotating rake will Zanthoxylum bungeanum fruit and Zanthoxylum bungeanum branch into the shell inside; The rake is provided with rake teeth, on the one hand, Zanthoxylum bungeanum branch is easy to extend into the rake teeth and then facilitate the rake to Zanthoxylum bungeanum fruit and Zanthoxylum bungeanum branch into the shell; On the other hand, with the rotation of the rake, the boss drives the cutting knife to move along the output shaft axial, and then the cutting tooth of the cutting knife and the rake tooth of the rake move oppositely, the gap between the cutting tooth and the rake tooth gradually reduces and then the Zanthoxylum bungeanum branch is cut off; Because the gap between the cutting tooth and the rake tooth reduces to form a barrier, the tender bud at the connection between Zanthoxylum bungeanum fruit and Zanthoxylum bungeanum tree is hindered to enter the shell, and even part of the tender bud at the connection between Zanthoxylum bungeanum fruit and Zanthoxylum bungeanum tree has not entered the shell, the cutting tooth and the rake tooth cooperate to cut off the Zanthoxylum bungeanum branch, the rake has no effect on the tender bud at the connection between Zanthoxylum bungeanum fruit and Zanthoxylum bungeanum tree, and then the tender bud at the connection between Zanthoxylum bungeanum fruit and Zanthoxylum bungeanum tree will not be damaged.
