Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural small-arch shed construction equipment, in particular to a shed pole continuous feeding device for agricultural small-arch shed construction equipment and a control method thereof. BACKGROUND

[0002] Small-arch shed planting technology has significant significance in agricultural production, especially in resource optimization and crop yield increase. It is widely used in the protective cultivation of vegetables, flowers and high-value crops. By constructing a simple arch structure, the microclimate environment is adjusted to effectively resist natural hazards such as frost, rain and wind, stabilize temperature and humidity, and reduce the occurrence of diseases and pests, thereby significantly improving crop yield and quality. Compared with large greenhouses, this technology is more economical and flexible, with low cost and convenient construction, especially suitable for small-scale growers. It can extend the growing season, achieve off-season marketing, enhance market supply stability, and promote sustainable development of agriculture. Under the challenge of climate change, small-arch sheds provide a feasible solution for efficient water use and ecologically friendly farming, promoting farmers' income and food security balance.

[0003] In the prior art, the applicant's prior application CN 116158296 A provides an automatic continuous feeding device for shed poles of an arch shed, which includes a stock bin, a first-stage separation mechanism composed of a belt with a material clamping groove, and a second-stage separation mechanism composed of left and right two material feeding clamps. This scheme has the following disadvantages in actual use: (1) Due to the length of the shed pole, it is inevitable that some shed poles will be slightly bent occasionally, so that the first-stage separation mechanism and the second-stage separation mechanism perform separation on different ends of the same shed pole, causing the shed pole to be disordered, stacked and bent during subsequent conveying, and even causing the equipment to be mechanically stuck or damaged; (2) The shed pole needs to be separated multiple times, first separated from the stock bin, and then separated again on the inclined table above, increasing the failure rate. The applicant's another prior application CN 114955466 A provides another shed pole feeding device, which includes an ejection mechanism and a shed pole separation mechanism. This patent technology also has the problem of increased failure rate due to two separations. In addition, although a sensor is provided in the shed pole separation mechanism for the second separation in the patent to detect the end of the shed pole to prevent the shed pole from rolling off, the problem of the two ejectors of the first-stage separation mechanism, i.e. the ejection mechanism, ejecting different ends of the shed pole cannot be solved. SUMMARY

[0004] The present application provides a shed pole continuous feeding device for agricultural small-arch shed construction equipment and a control method thereof, which can timely detect whether the shed pole separation is problematic and prevent the shed pole or the equipment from being damaged due to shed pole separation errors.

[0005] Technical solution: To achieve the above-mentioned purpose, the agricultural small greenhouse construction equipment shed pole continuous pole throwing device of the application comprises a shed pole containing bin, a shed pole separation mechanism, a shed pole conveying mechanism and a control system; the shed pole separation mechanism comprises left and right two groups of separation components, each group of separation components comprises a separation piece and a driving unit for driving the separation piece to move up and down in the shed pole containing bin, and the driving unit can be a pneumatic cylinder or an electric push rod;

[0006] The shed pole conveying mechanism comprises two groups of parallelly arranged belts, and a plurality of interval blocks are equidistantly installed on each group of belts;

[0007] The shed pole separation mechanism and the shed pole conveying mechanism are provided with a connection detection mechanism therebetween;

[0008] The connection detection mechanism comprises left and right two clamping mechanisms, a slide rail for guiding the clamping mechanisms, and a horizontal pulling unit connecting the clamping mechanisms, a tension sensor is arranged between the horizontal pulling unit and the clamping mechanisms, and the tension sensor is connected to the control system;

[0009] The clamping mechanism comprises a sliding seat capable of sliding along the slide rail, the sliding seat is provided with a first clamping block and a second clamping block oppositely installed thereon, the first clamping block is capable of translating up and down relative to the sliding seat under the driving of a translation driving unit; the second clamping block is capable of translating left and right relative to the sliding seat, and a spring is arranged between the two clamping blocks, and the lower side of the second clamping block is provided with a V-shaped protruding portion.

[0010] The clamping mechanism is located above the separation piece and is staggered with the separation piece, and the clamping mechanism is located on the side of the belt; by adopting the above structure, during operation, the driving unit of the shed pole separation mechanism drives the separation piece to top, the separation piece drives the shed pole to move upward, when the shed pole moves upward, the shed pole contacts the protruding portion of the second clamping block and pushes the second clamping block away to compress the spring, after the shed pole reaches above the protruding portion, the spring resets to make the first clamping block and the second clamping block clamp the shed pole. Then, the two horizontal pulling units apply opposite pulling forces to the two clamping mechanisms, when the two clamping mechanisms clamp the same shed pole, the two tension sensors both generate a larger pulling force value, thereafter, the translation driving unit drives the first clamping block to move upward, the spring continues to release the elastic force, and the second clamping block pushes the shed pole to the gap between the adjacent two interval blocks on the belt.

[0011] Further, the first clamping block has a structure of thick top and thin bottom, and a first transition slope between the thick section and the thin section; the lower end of the thin section has a second transition slope which can contact the upper slope of the convex part. During operation, the first transition slope, the inward side of the thin section and the upper slope of the convex part all play a clamping role on the shed pole, so as to maintain the clamping stability.

[0012] After the detection of the shed pole, the first clamping block moves upward, the second clamping block pushes the shed pole out, then the translation driving unit drives the second clamping block to move downward, during the downward movement of the second clamping block, the second transition slope on the second clamping block contacts the upper slope of the convex part to extrude the second clamping block, so as to make the second clamping block return to the translation movement and compress the spring part.

[0013] Further, the belt has a triangular layout with a vertical extension section and a horizontal extension section. During operation, the shed pole is pushed by the detection mechanism to the gap on the vertical extension section, and then is transferred from the vertical extension section to the horizontal extension section along with the belt, and finally is separated from the end of the horizontal extension section to complete the pole throwing.

[0014] Further, the top end of the separating piece has a slope, and the separating piece moves along the wall of the shed pole containing bin, so that the slope of the top end of the separating piece and the wall form a containing groove for containing the shed pole.

[0015] Further, the second clamping block has a rubber pad on the clamping surface, so as to prevent the shed pole from slipping relative to the clamping mechanism during the horizontal pulling of the horizontal pulling unit on the clamping mechanism.

[0016] Based on the above-mentioned control method of the shed pole continuous throwing device of the agricultural small shed building device, the control method comprises:

[0017] Step S1, controlling the driving unit to make the separating piece rise; during the rising of the separating piece, each separating piece supports a pole end to rise, and the pole end pushes away the convex part to enter between the first clamping block and the second clamping block during the rising of the pole end;

[0018] Step S2, controlling the horizontal pulling unit to horizontally pull the clamping mechanism, obtaining the pulling force value generated by the pulling force sensor, and judging whether the pulling force value is greater than a preset threshold value;

[0019] Step S3, when the pulling force value is greater than the preset threshold value, controlling the translation driving unit to operate to make the first clamping block rise, so that the shed pole leaves the clamping mechanism and enters the gap of the shed pole conveying mechanism, and then controlling the translation driving unit to operate to make the first clamping block descend;

[0020] Step S4, when the pulling force value is less than the preset threshold value, the alarm unit issues an alarm and the device stops operating.

[0021] Beneficial effects: the agricultural small greenhouse construction equipment shed pole continuous pole throwing device and its control method has the following beneficial effects:

[0022] (1) In the present application, by setting the connection detection mechanism, the shed pole separated by the shed pole separation mechanism can be clamped at both ends and detected, and it is judged whether the two clamping mechanisms clamp the two ends of the same shed pole, to prevent the two separating pieces from ejecting the same shed pole due to the bending of the shed pole, and to avoid the phenomenon of subsequent shed pole disorder, bending and even equipment damage.

[0023] (2) In the process of separating the shed pole from the shed pole storage bin by the shed pole separation mechanism, the clamping mechanism can assist in clamping the end of the shed pole, so that the operation process is smooth, and in the process of descending and then rising of the subsequent separating piece, the translation driving unit can directly pull horizontally for detection and push the detected horizontal pole to the shed pole conveying mechanism, increasing the compactness of the timing and improving the efficiency of the system operation.

DETAILED DESCRIPTION

[0033] The application will be further described below in conjunction with the accompanying drawings.

[0034] As Figure 1 and Figure 2 shown, the pole continuous feeding device for the agricultural small greenhouse building device includes a pole storage bin 1, a pole separation mechanism 2, a pole conveying mechanism 3, and a control system; the pole separation mechanism 2 includes left and right two groups of separation assemblies, as Figure 4 shown, each group of separation assemblies includes a separation piece 21 and a driving unit 22 for driving the separation piece 21 to move up and down in the pole storage bin 1, and the driving unit 22 can be a pneumatic cylinder or an electric push rod;

[0035] The pole conveying mechanism 3 includes two groups of parallelly arranged belts 31, and a plurality of spacer blocks 32 are equidistantly installed on each of the belts 31; the belts 31 are driven to move step by step by a driving motor.

[0036] As Figure 3 shown, the pole separation mechanism 2 and the pole conveying mechanism 3 are provided with a connection detection mechanism 4 therebetween;

[0037] As Figure 5 and Figure 6 shown, the connection detection mechanism 4 includes left and right two clamping mechanisms 41, a slide rail 42 for guiding the clamping mechanisms 41, and a transverse pulling unit 43 connecting the clamping mechanisms 41, and a tension sensor 44 is arranged between the transverse pulling unit 43 and the clamping mechanisms 41, and the tension sensor 44 is connected to the control system;

[0038] As Figure 5 shown, the clamping mechanism 41 includes a sliding seat 411 capable of sliding along the slide rail 42, and the sliding seat 411 has a first clamping block 412 and a second clamping block 413 oppositely installed thereon, the first clamping block 412 is capable of translating up and down relative to the sliding seat 411 under the driving of a translation driving unit 414; the second clamping block 413 is capable of translating left and right relative to the sliding seat 411, and a spring 415 is arranged therebetween, and the lower side of the second clamping block 413 has a V-shaped protrusion a.

[0039] The clamping mechanism 41 is located above the separating piece 21 and staggered with each other, and the clamping mechanism 41 is located on the side of the belt 31; by adopting the above structure, during operation, the driving unit 22 of the shed pole separating mechanism 2 drives the separating piece 21 to top, the separating piece 21 drives the shed pole to move upward, when the shed pole moves upward, the shed pole contacts the protruding part a of the second clamping block 413, and the second clamping block 413 is pushed away to make the spring 415 compressed, after the shed pole reaches above the protruding part a, the spring 415 resets to make the first clamping block 412 and the second clamping block 413 clamp the shed pole, as shown in the figure. Figure 6 Then, the two horizontal pulling units 43 apply opposite pulling forces to the two clamping mechanisms 41, when the two clamping mechanisms 41 clamp the same shed pole, the two pulling force sensors 44 all generate a larger pulling force value, thereafter, the translation driving unit 414 drives the first clamping block 412 to move upward, the spring 415 continues to release the elastic force, and the second clamping block 413 pushes the shed pole to the gap between the adjacent two interval blocks 32 on the belt 31, as shown in the figure. Figure 7 If the two clamping mechanisms 41 do not clamp the same shed pole, then the two pulling force sensors 44 all generate a smaller pulling force value, at this time, the control system makes the alarm unit issue an alarm and makes the device stop running through the connection.

[0040] In the present application, by arranging the connection detection mechanism 4, the shed pole separated by the shed pole separating mechanism 2 can be clamped at both ends and detected to judge whether the two clamping mechanisms 41 clamp the two ends of the same shed pole, so as to prevent the two separating pieces 21 from ejecting the same shed pole due to the bending of the shed pole, and avoid the phenomenon of subsequent shed pole disorder, bending and even equipment damage.

[0041] During the process of separating the shed pole from the shed pole containing bin 1 by the shed pole separating mechanism 2, the clamping mechanism 41 can assist in completing the clamping operation of the end of the shed pole, so that the operation process is smooth, and during the subsequent descending and ascending process of the separating piece 21, the translation driving unit 414 can directly horizontally pull for detection and push the horizontal rod that passes the detection to the shed pole conveying mechanism 3, which increases the compactness of the time sequence, improves the rhythm of system operation, and improves the efficiency.

[0042] Preferably, the first clamping block 412 has an upper thick and lower thin structure, and a first transition slope b is arranged between the thick body segment and the thin body segment; the lower end of the thin body segment has a second transition slope c, which can contact the upper slope of the protruding part a. During operation, the first transition slope b, the inward side surface of the thin body segment and the upper slope of the protruding part a all play a clamping role on the shed pole, which can maintain the clamping stability.

[0043] After the detection of the shed pole is completed, the first clamping block 412 moves upward, the second clamping block 413 pushes the shed pole out, and then the translation driving unit 414 drives the second clamping block 413 to move downward. During the downward movement of the second clamping block 413, the second transition slope c on the second clamping block 413 is in contact with the upper slope of the protruding part a, so as to extrude the second clamping block 413, make the second clamping block 413 retreat from the translation movement, and partially compress the spring 415.

[0044] Preferably, the belt 31 is in a triangular layout, which has a vertical extension section 31a and a horizontal extension section 31b. During operation, the shed pole is pushed by the detection mechanism 4 into the gap on the vertical extension section 31a, and then is transferred from the vertical extension section 31a to the horizontal extension section 31b along with the operation of the belt 31, and finally is separated from the end of the horizontal extension section 31b to complete the pole throwing.

[0045] By making the belt have the vertical extension section 31a and the horizontal extension section 31b, the continuity of the shed pole conveying can be achieved, and the pole throwing operation does not need to be performed multiple times, so that the failure rate can be reduced.

[0046] Preferably, as shown in the drawings, the top end of the separating piece 21 has a slope, and the separating piece 21 moves along the wall of the shed pole accommodating bin 1, so that the slope at the top end of the separating piece 21 and the wall form an accommodating groove for accommodating the shed pole. Figure 6

[0047] Preferably, the clamping surface of the second clamping block 413 has a rubber pad, so that the shed pole can be prevented from slipping relative to the clamping mechanism 41 during the horizontal pulling of the horizontal pulling unit 43 on the clamping mechanism 41.

[0048] Based on the above-mentioned control method of the shed pole continuous throwing device of the agricultural small shed erecting device, the control method comprises the following steps:

[0049] In step S1, the driving unit 22 is controlled to drive the separating piece 21 to move upward, and during the upward movement of the separating piece 21, each separating piece 21 supports a pole end to move upward, and during the upward movement of the pole end, the protruding part a is extruded to enter between the first clamping block 412 and the second clamping block 413.

[0050] In step S2, the horizontal pulling unit 43 is controlled to horizontally pull the clamping mechanism 41, the pulling force value generated by the pulling force sensor 44 is obtained, and whether the pulling force value is greater than a preset threshold value is judged.

[0051] In step S3, when the pulling force value is greater than the preset threshold value, the translation driving unit 414 is controlled to drive the first clamping block 412 to move upward, so that the shed pole is separated from the clamping mechanism 41 and enters the gap of the shed pole conveying mechanism 3, and then the translation driving unit 414 is controlled to drive the first clamping block 412 to move downward.

[0052] ​Step S4, when the tension value is less than a preset threshold, the alarm unit is caused to issue an alarm and the device is caused to stop running.

[0053] The above only describes the preferred embodiments of the present application, and it should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered within the protection scope of the present application.
