Description

Technical Field

[0001] The invention relates to the field of agricultural product processing equipment, and in particular to automatic cutting equipment for crop processing. Background Art

[0002] With the rapid development of the national economy, people's demand for agricultural products is not limited to basic factors such as price and freshness. In the current agricultural product market, the appearance is often more important than the price, because agricultural products with better appearance are more popular and can be sold at higher prices. For example, by sorting, sorting and classifying according to size and specifications and selling at different prices, the profit is often higher than selling different sizes together; or by manual or mechanical cutting, processing agricultural products into similar sizes and specifications and then packaging and selling them, it can also obtain relatively high economic benefits.

[0003] In order to improve processing efficiency, automated cutting equipment is widely used in the field of agricultural product processing. Among them, agricultural products with a roughly stick-shaped appearance are most convenient to be processed by automated cutting equipment, such as king oyster mushrooms, carrots, corn, etc. In the supermarket vegetable market, we can already see such agricultural products cut into vacuum-packed products of roughly the same length.

[0004] The difficulty of automated processing of King Oyster Mushroom is greater because, compared with carrots and corn, King Oyster Mushroom is generally stick-shaped, but it is generally soft and not very straight. After the root of King Oyster Mushroom is cut off, the blade is smooth but not beautiful enough, so most merchants will further trim the end of the King Oyster Mushroom after cutting off the root, trimming the end of the King Oyster Mushroom into a bullet-like shape.

[0005] Based on the above market demand, the patent of the present invention provides a cutting device for fully automatic processing of Pleurotus eryngii, which is used to achieve root resection, root trimming and final automatic sorting of Pleurotus eryngii according to size specifications.

[0039] like Figure 3 and Figure 5 As shown, the auxiliary clamping mechanism includes a finger cylinder 5e and a clamping block 5f installed on the finger cylinder 5e. When the auxiliary clamping mechanism is in a standby state, the finger cylinder 5e is in an open state. When the clamping claw 10 loaded with the crop product moves to face the finger cylinder 5e, the finger cylinder 5e moves and clamps the root of the crop product through the clamping block 5f. It should be noted that when the finger cylinder 5e is in an open state, the two clamping blocks 5f do not affect the movement of the crop product to face the finger cylinder 5e.

[0040] like Figure 5 As shown, the transverse cutting mechanism includes a first guide rail 5a, a first sliding seat 5b and a first cylinder 5c. The first sliding seat 5b is slidably installed on the first guide rail 5a. The front end of the push rod of the first cylinder 5c is connected to the first sliding seat 5b. The ejection reverse direction of the first cylinder 5c is the same as the extension direction of the first guide rail 5a. The transverse cutter 5d is installed at the bottom of the first sliding seat 5b and extends vertically downward.

[0041] like Figure 5 and Figure 6As shown, a movable side plate 1b is provided in the equipment body 1 which is parallel to and located outside the fixed side plate 1a, all root trimming devices 6 are installed on the movable side plate 1b and are located between the movable side plate 1b and the fixed side plate 1a, and a first spacing control mechanism for controlling the spacing between the movable side plate 1b and the fixed side plate 1a is also provided in the equipment body 1. In a specific embodiment of the present invention, the first spacing control mechanism includes a first driving motor 8a, a light rod guide assembly 8b and a screw assembly 8c. The light rod in the light rod guide assembly 8b is fixedly connected to the fixed side plate 1a and extends perpendicular to the fixed side plate 1a to both sides of the equipment body 1.

The first driving motor 8a is installed in the equipment body 1. The extending end of the screw and the output end of the first driving motor 8a are connected by a synchronous belt drive. The first driving motor 8a drives the screw to rotate and thereby drives the movable side plate 1b to move relative to the fixed side plate 1a, thereby driving the root trimming device 6 to trim the roots of the crop products along the direction in which they extend.

[0042] refer to Figure 2 , Figure 5 and Figure 7 As shown, each of the root trimming devices 6 includes a second guide rail 6a and two second sliding seats 6b slidably mounted on the second guide rail 6a, the second guide rail 6a is mounted on the movable side plate 1b, and each second sliding seat 6b is mounted with an extension tool holder 6c vertically passing through the fixed side plate 1a, preferably, the extension tool holder 6c is preferably made of spring steel, and a longitudinal cutter 6e perpendicular to the extension tool holder 6c is mounted at the front end of each extension tool holder 6c, the two longitudinal cutters 6e are parallel and spaced apart, and the root trimming device 6 also includes a second spacing controller for controlling the spacing between the two longitudinal cutters 6e.

[0043] like Figure 7 As shown, the number of root trimming devices 6 is N, and N is an even number greater than or equal to 4; n is the serial number of the nth root trimming device 6; a n is the inclination angle between the longitudinal cutter 6e in the nth root trimming device 6 and the horizontal plane; when n is 1, a n is any value; when n is an even number, a n =a n-1 +180; when n is an odd number, a n =a n-1 +90 / N / 2.

[0044] like Figure 8As shown, the second spacing controller includes two second cylinders 9a, the front end of the ejector rod of the second cylinder 9a is connected to the second sliding seat 6b, and the ejection direction of the second cylinder 9a is the same as the extension direction of the second guide rail 6a.

[0045] refer to Fig.11 and Figure 2 As shown, each second sliding seat 6b is equipped with a linkage rod 6d that vertically passes through the movable side plate 1b, and a linear slide groove 1b1 is provided on the movable side plate 1b for the linkage rod 6d to pass through. The linear slide groove 1b1 extends from the middle of the second guide rail 6a to the end of the linear guide rail, and the extension directions of the two linear slide grooves are opposite and parallel to the second guide rail 6a; the second spacing controller includes a rotating disk 9b installed on the back side of the movable side plate 1b and rotating around a horizontal rotation axis and a turntable driver that drives the rotating disk 9b to rotate, the rotating disk 9b is provided with a first guide groove 9b1, and the front end of the linkage rod 6d is equipped with a first guide wheel in the first guide groove 9b1; when the rotating disk 9b rotates forward, the two linkage rods 6d move respectively along the extension direction of the linear slide groove 1b1, thereby driving the two second sliding seats 6b away from each other; when the rotating disk 9b rotates reversely, the two linkage rods 6d move respectively along the opposite direction of the extension direction of the linear slide groove 1b1, thereby driving the two second sliding seats 6b closer to each other.

[0046] refer to Fig. 9 and Fig.10 As shown, the first guide groove 9b1 is a linear groove whose width is greater than the diameter of the first guide wheel. The linear groove has a first groove wall 9b11 and a second groove wall 9b12. When the rotating disk 9b rotates forward, the first groove wall 9b11 contacts the first guide wheel. When the rotating disk 9b rotates reversely, the second groove wall 9b12 contacts the first guide wheel. Fig.10 The rotation state 1 to the rotation state 3 shown in the figure is that the rotating disk 9b rotates forwardly, such as counterclockwise rotation in the figure, and the linkage rod 6d moves in the linear slide groove 1b1 during the rotation process. The position of the linkage rod 6d is limited by the linear slide groove 1b1 and the first guide groove 9b1. When the rotating disk 9b stops during the rotation process, the linkage rod 6d is locked. That is, the distance between the two longitudinal cutters 6e is completely limited by the rotation angle of the rotating disk 9b.

[0047] refer to Fig.12 and Fig.13As shown, the first guide groove 9b1 has a third groove wall 9b13, a fourth groove wall 9b14 and a fifth groove wall 9b15, and the third groove wall 9b13, the fourth groove wall 9b14 and the fifth groove wall 9b15 are connected end to end in sequence, and the orthographic projection of the fourth groove wall 9b14 on the rotating disk 9b is an arc line. When the rotating disk 9b rotates forward, the fourth groove wall 9b14 contacts the first guide wheel. When the first guide wheel moves to the maximum distance in the linear slide groove 1b1, the first guide wheel can at least contact the fourth groove wall 9b14, and the orthographic projection of the fourth groove wall 9b14 on the rotating disk 9b is an arc line segment, and the center of the arc line segment is on the rotation axis of the rotating disk 9b. The root trimming device 6 is also provided with a second tension spring 6f, which is used to apply a pulling force to the second sliding seat 6b along the end of the second guide rail 6a toward the middle of the second guide rail 6a. Fig.13 The active state 3 to the rotation state 6 shown in the figure is that the rotating disk 9b rotates forward, that is, counterclockwise, as shown in the figure. During the rotation process, the third groove wall 9b13 contacts the guide wheel and pushes the linkage rod 6d to overcome the tension of the second tension spring 6f in the linear slide groove 1b1 and move along the linear slide groove 1b1. If the rotating disk 9b stops rotating during this rotation process, the linkage rod 6d can overcome the tension of the second tension spring 6f under the action of external force and move in the linear slide groove 1b1. Because the diameter of the Pleurotus eryngii is not uniform in the length direction, the longitudinal cutter 6e may encounter a thicker diameter part of the Pleurotus eryngii during the movement of the movable side plate 1b. In this case, if the distance between the two longitudinal cutters 6e is locked, the longitudinal cutter 6e will cause the Pleurotus eryngii to cut to a greater depth. Excessive cutting depth may not only lead to excessive removal of pulp and excessive weight loss, but may also cause the blade to get stuck, and the Pleurotus eryngii may be directly pulled apart, resulting in poor appearance. Fig.12 As shown in the middle rotation state 7, when the rotating disk 9b rotates in the opposite direction or is stuck, the linkage rod 6d is not locked in the linear slide groove 1b1. In this case, under the action of the second tension spring 6f, the longitudinal cutter 6e will cut closely to the surface of the Pleurotus eryngii without cutting too deep, and can better adapt to the undulations of the surface of the Pleurotus eryngii.

[0048] refer to Figure 7 and Fig. 9 As shown, the turntable drive includes a third cylinder 9c and a long connecting rod 9d, the top rod of the third cylinder 9c is horizontal and perpendicular to the rotating axis of the rotating disk 9b, the long connecting rod 9d is connected to the top rod of the third cylinder 9c, and the long connecting rod 9d is eccentrically connected to each rotating disk 9b.

[0049] refer to Figure 1 and Figure 2As shown, the feeding device 2 has four parallel and spaced feed conveyor belts 2a, the four feed conveyor belts 2a rotate synchronously and the conveying direction is consistent with the conveying direction of the stepping conveyor, two adjacent feed conveyor belts 2a are connected to a row of clamping jaws 10 groups, and each feed conveyor belt 2a is equipped with a baffle plate 2b.

[0050] refer to Figure 1 and Figure 3 As shown, the discharging and sorting device 3 includes a discharging conveyor belt 3a, the discharging direction of the discharging conveyor belt 3a is perpendicular to the conveying direction of the stepping conveyor, the width of the discharging conveyor belt 3a is greater than the length of the second track segment, and a plurality of drop baffles 3b are located above the discharging conveyor belt 3a in the equipment body 1, and an anti-roll bar 3c is also arranged above the discharging conveyor belt 3a and below each drop baffle 3b, and a gap is provided between the anti-roll bar 3c and the conveying surface of the discharging conveyor belt 3a, and the anti-roll bar can effectively prevent the crop products from falling onto the discharging conveyor belt 3a and rolling sideways.

[0051] refer to Figure 3 As shown, the waste guiding device includes a waste baffle 19 and a sweeping brush not shown in the figure. The waste baffle 19 is horizontally installed below the clamp 10 in the second track section, and the sweeping brush is installed below the clamp 10 on the side facing the cutting mechanism.

[0052] refer to Figure 3 and Figure 4 As shown, the clamp 10 includes a frame body 10a and two claw bodies 10b. The roots of the two claw bodies 10b are hingedly installed in the frame body 10a through an axis, and the heads of the two claw bodies 10b extend to the outside of the frame body 10a. A first tension spring 10c is connected between the middle parts of the two claw bodies 10b. Under the tension of the first tension spring 10c, the clamp 10 is in a closed state.

[0053] refer to Figure 3 As shown, the root of each claw body 10b is provided with a first inclined surface, and the two first inclined surfaces form a V-shaped groove 10d. The locking driver is provided with a first movable block 11 that can move upward, and the front end of the first movable block 11 has an insertion portion that can be inserted into the V-shaped groove 10d, so that the clamping jaw 10 is in a locked state and does not loosen under the action of external force. The first movable block 11 moves upward through the waste baffle 19.

[0054] refer to Figure 4As shown, the clamping jaw 10 also includes two linkage blocks 12 arranged on the outside of the frame body 10a and fixedly connected to the shaft body of the claw body 10b respectively. A second inclined surface is provided at the bottom of each linkage block 12, and the inclination direction of the second inclined surface is opposite to the inclination direction of the first inclined surface. The first opening driver and the second opening driver have the same structure and both have a second movable block 13. The front end of the second movable block 13 has a resistance surface that can contact the two linkage blocks 12 at the same time. When the second movable block 13 contacts the two linkage blocks 12, the two linkage blocks 12 are driven to rotate synchronously in the opposite direction, thereby driving the two claw bodies 10b to rotate to realize the opening of the clamping jaw 10. When the resistance surface contacts the two second inclined surfaces, the clamping jaw 10 is in the maximum opening state.

[0055] refer to Figure 4 As shown, the two linkage blocks 12 are provided with teeth that mesh with each other. Since the two linkage blocks 12 are linked by teeth, not only the rotation angles of the two claw bodies 10b are ensured to be consistent, but also the shaking of the claw body 10b during the movement of the clamping jaw 10 can be effectively avoided, thereby ensuring the stability of the posture of the clamping jaw 10 during the movement.

[0056] refer to Figure 5 As shown, the stepping conveyor is provided with two conveying chains 15 and a chain driving motor 16 for driving the conveying chains 15 to rotate. There are a plurality of connecting rods 17 in a horizontal state between the two conveying chains 15. The two connecting rods 17 constitute a mounting frame for mounting the clamping jaws 10.

[0057] The step conveyor is also provided with two vertically arranged mounting side plates 18, the inner sides of the two mounting side plates 18 are provided with second guide grooves 18a cooperating with the ends of the connecting rod 17, and second guide wheels capable of rolling in the second guide grooves 18a are installed at both ends of the connecting rod 17.

[0058] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
